Two bishop moves


Here is a nice game won by the future grandmaster Peter Leko when he was only 12 years old. Keep an eye on White's light-squared bishop!

Leko,P (2460) - Ruzele,D (2340)
Debrecen 1992
French Defence C11

1.e4 e6 2.d4 d5 3.Nc3 Nf6 4.e5 Nfd7 5.f4 c5 6.Nf3 Nc6 7.Be3 cxd4 8.Nxd4 Bc5 9.Qd2 Bxd4 10.Bxd4 Nxd4 11.Qxd4 Qb6

This plan involving massive exchanges on d4 was introduced by Gideon Stahlberg in 1960. Over the years it has attracted sporadic attention, notably from Mikhail Gurevich and Viktor Korchnoi. At the grandmaster level it is a fairly safe way to play for a draw with the Black pieces, but anyone at a lower level is not going to have an enjoyable time. By the way, Stahlberg lost that first game -- to Mikhail Tal.

12.0–0–0 Qxd4 13.Rxd4 Ke7 14.h4!

A nice, thematic move. If unopposed, White will set up his pawns on e5, f4 g4, and h5, and threaten a breakthrough at an appropriate moment. Black's next move opposes this plan but it has the disadvantage of fixing his kingside pawns on light squares.

14...h5

Leko mentioned 14...f6 in Informant 56, but this lets White get a clear advantage after 15.exf6+ gxf6 16.f5! Nb6 17.fxe6 Bxe6 18.Bd3.

15.Be2 Nb8 16.Rd2 Bd7 17.Rhd1 g6

This must be played sooner or later; otherwise Black will be unable to move his rook from h8.

18.b3! Bc6!?

And not 18...Nc6 on account of 19.Ne4! with advantage to White, for example, 19...Rhd8 20.Nd6 b6 21.c4! and Black is in difficulties.

19.Bf3 Nd7 20.Ne2 Rhc8

Pressure along the c-file is Black's only active plan. Almost everything else will create weaknesses. But with White's king on hand to defend the queenside it is unlikely that Black will achieve anything concrete.

21.Nd4 Rc7 22.Kb2 Nb6 23.Rd3!

Not 23.a4? Bxa4! 24.bxa4 Nc4+ followed by 24...Nxd2 with decent play for Black.

23...Bd7 24.a4! a5 25.Be2

White has taken control of the key square b5 and now has possibilities on both wings.

25...Rac8 26.Rh3 Bc6 27.Rg1 Rh8

It was probably better to recycle the knight with 27...Nd7.

28.Rc3!

Threatening to attack the pawn on a5.

28...Nd7 29.Rh1 Rcc8 30.Rhh3 Rhg8

By alternating play on both wings, White has brought all his pieces to active positions while Black has been forced into passivity. It is now time to strike.


31.Ba6!

A nice combination of tactics and strategy, opening up the position and exposing Black to further attack. "A weakness of the dark squares is also a weakness of the light squares," wrote David Bronstein.

31...f6

Black is losing a pawn, so he tries to gain some activity. If 31...Nb8 then 32.Nxc6+ Rxc6 33.Bxb7 Rxc3 34.Rxc3 Kd7 35.Ka3 with the idea of 36.b4 with a winning position for White.

32.exf6+ Nxf6 33.Nxc6+

Now that e6 has been weakened, it was also possible to play 33.Rce3 Ne4 34.Bd3 Nc5 35.Rhg3 with continuing pressure for White.

33...Rxc6 34.Bxb7 Rb6 35.Rc7+ Kd6 36.Rhc3 Ne4

In Informant Leko gave the line 36...Rb8 37.Rf7 Ne4 38.Rcc7 as winning for White, but there is a huge flaw in this: 38...Nc5! 39.Bc8 Nxa4+ 40.Kc1 Nc5 and Black is suddenly much better.

After 36...Rb8 the right idea is 37.Bc8! d4 38.R3c4 Kd5 39.Re7, when Black is more or less in zugzwang; for example, 39...Ke4 (or 39...Ne4 40.Kc1 Nc5 41.Rc7 Ne4 42.Bd7) 40.Rxe6+ Rxe6 41.Bxe6 Kxf4 42.Bf7 Rd8 43.Bxg6 Kg3 44.Rc5 Kxh4 45.Rf5 Nd5 46.Bxh5 Ne3 47.Rxa5 Nxg2 48.Be2 and White must be winning.

37.R3c6+ Rxc6 38.Rxc6+ Kd7 39.Ra6! Kc7

Leko gave 39...Nc5 40.Rb6! and wins. One should also mention 39...Rf8, on which there could follow 40.Bc6+ Kc7 41.Bb5 Rxf4 42.Rxe6 Rg4 43.Be8 Rxg2 44.Rc6+ Kb8 45.Rxg6 Rh2 46.Ra6 Rxh4 47.Rxa5 Nf6 48.Bf7 d4 49.b4 Rh3 50.Rf5 and wins.


40.Ba8! Rf8 41.c4! Rxf4 42.cxd5 e5 43.Rxa5

Another way forward was 43.Rxg6 Rxh4 44.Re6 Nf2 45.Kc2, etc.

43...Rxh4

If 43...Rf2+ 44.Ka3 Rxg2 then 45.d6+.

44.d6+! Nxd6

Or 44...Kxd6 45.Ra6+ Kc7 46.Rxg6 Nd6 47.Rg5.

45.Rxe5 Kb8

If 45...Rxa4 then 46.Rc5+, etc.

46.Bd5 Rg4 47.a5 Rd4 48.Bf3 Nf5 49.Kc3 Rf4 50.Re4 Rh4 51.Rxh4 Nxh4 52.Be4 1–0

In many ways a typical game from the modern era. Strategically, White's play was not too complicated, but the key to success was the exploitation of Black's weaknesses with exactly calculated tactical play. White got his attack in first and Black's counterplay was just too slow. Bobby Fischer won a lot of games this way!

Geller vs Suetin, Moscow Team Ch. 1981


Today we present a little-known but pleasing attacking game by the Ukrainian grandmaster Efim Geller, a perennial world championship candidate but arguably never a serious contender for the title. His opponent, the second-tier Russian grandmaster Alexei Suetin, famously had his face slapped by Mrs Rona Petrosian after failing to match the depth and accuracy of Bobby Fischer's adjournament analysis during the 1971 Candidates Final in Buenos Aires. However, Suetin's book A Contemporary Approach to the Middlegame is an acknowledged classic, so we'll cut him some slack and thank him for his unintended role in Fischer's ascent to the throne in 1972.

A personal view: when forced to defend against 1.e4, the Sicilian Defence is best deployed against the relatively weak or the very strong. Anyone possessing a modicum of chessic common sense knows that playing 1...c5 demands a good theoretical knowledge base, a storehouse of experience, and a willingness to take calculated risks. All fine if you have those things, but otherwise you're just asking for trouble. If proper preparation prevents poor performance, then mutatis mutandis insufficient investigation involves inevitable inadequacy.

Despite his reputation as something of an also-ran, Efim Geller made a number of contributions to opening theory, one of which is seen in our game today. Most Black warriors are pleasantly surprised by the appearance of the move c2-c3 in the Sicilian Defence because it takes away the natural square from White's queen knight, thereby diminishing the first player's control over the squares e4 and d5. It also signals that White is perhaps a denizen of the lower chess classes. Of course Black will usually try to punish this lacklustre approach with a well-timed d7-d5, but in today's game there is something about his previous moves ...a6 and ...Bc5 that doesn't quite square with this simplistic program. Geller had already taken note of this back in 1969 when he successfully introduced 6.c3 against Mark Taimanov in that year's Soviet Championship. So... 12 years on and time for another outing...

Geller – Suetin
Moscow Team Championship 1981
Sicilian Defence B42

1.e4 c5 2.Nf3 e6 3.d4 cxd4 4.Nxd4 a6 5.Bd3 Bc5 6.c3

White can play for an edge with 6.Nb3 Be7 7.Qg4!? g6 8.Qe2 d6 9.0-0 Nd7 and now 10.Na3!? is interesting.

6...Ne7 7.0-0 Nbc6 8.Be3 Qb6?

When Black wants to punish or at least annoy White in the opening, he often forgets about castling and reaches for his queen. This particular expedition cannot end happily. Normal would be 8...d6 9.Nd2 0-0 and Black seems to be OK.

9.Nd2!

I like a game with interesting moments. One guy makes a threat, the other guy makes a move that allows the threat, and then the first guy realises that the threat doesn't work. Have a look:
A. 9...Qxb2? 10.Nc4! Qxc3 11.Rc1 Qb4 12.a3 and wins;
B. 9...Nxd4? 10.cxd4 Bxd4 11.Nc4 Qa7 12.Nd6+ Kf8 13.Qh5 and wins.

9...d5

A freeing move? Not really – Black's king is still in the centre.

10.N2b3! Bxd4 11.cxd4 dxe4

Black should castle and hope for the best.

12.Bxe4 Qd8?!

If 12...Nd5 then 13.Qg4! Kf8 (13...0-0? 14.Bh6 winning the exchange) 14.Qf3 and Black will find it very difficult to untangle himself.

13.Qh5! Nd5 14.Bg5 Nce7 15.Rfe1 h6 16.Rad1 Qd6

In Informant 32 Minic and Sindik gave the cryptic 16...0-0 17.Bxh6! without further comment. White has very good compensation for the piece after 17...gxh6 18.Qxh6 f5 19.Bxd5 Nxd5 20.Rd3 Qf6 21.Rg3+ Kf7 22.Qh7+ Ke8 23.Nc5, but it's not clear that he's actually winning.

After 16...0-0, Black is not in fact threatening to capture the bishop, so White should take the opportunity to bring another piece into action. After 17.Rd3! there are two main variations:
A. 17...f5 18.Bxd5 hxg5 19.Rxe6 Qxd5 20.Rxe7 f4 21.Qg6 Rf7 22.Re5 Qd8 23.Rxg5 and White is winning;
B. 17...Qe8 18.Bxh6 f5 19.Qg5 Rf7 20.Bxd5 Nxd5 21.Rg3 Qe7 22.Qg6 f4 23.Rg4 Qf6 24.Qh5 f3 25.Re5 fxg2 26.f4! and the assault on g7 spells doom for Black.

After the text move 16...Qd6 we are at another interesting moment. Geller knows what to do.



17.Bxe7! Nxe7 18.d5! exd5

Or 18...e5 19.Bb1, etc.

19.Bxd5 Qf6

The alternative 19...Qg6 does not help in view of 20.Bxf7+! Kxf7 21.Rxe7+ and wins.

20.Bxf7+!

Seeing that 20...Qxf7 loses immediately to 21.Rd8+, Black threw in the towel here.

Wonderful play from Geller to down a lower-ranked colleague. Unfortunately for him, his higher-ranked colleagues Korchnoi, Spassky, and Tal did not allow such things to happen.

Alekhine vs Levenfish, Moscow 1920

It is a little-known fact that the winner of the first Soviet Championship in 1920 was none other than Alexander Alekhine. The contemporary title of the event was the First All-Russian Chess Olympiad, and it was only after 1922 – when the Soviet Union was formally established – that it was subsumed as part of the continuing series. Alekhine, of course, left his homeland in 1921, never to return. After his match victory over Capablanca in 1927, he reportedly made some anti-Soviet statements to a gathering of emigre Russians in Paris. His former compatriots immediately declared him persona non grata, and he was not rehabilitated until after the death of Stalin.

Along the way to winning the title in 1920, Alekhine had to survive a very difficult encounter with Grigory Levenfish (who won the title himself in 1937). Today we present an extract from Sergei Voronkov's 2007 book Masterpieces and Dramas from the Soviet Championships, 1920-1937. We pick up the action after Levenfish's 31st move ...Kg8-h7. From now on the commentary is by Voronkov.



32.Kg4!!


“The only way to draw,” exclaims Alekhine [in his 1921 book Schachleben in Sowjet-Russland - tr]. “If first 32.Qd3+ g6 and now 33.Kg4, then 33...f5+ 34.exf6 h5+ and wins.”


Alexander Kotov in his book Alekhine's Chess Heritage (1982) shows exactly how: “After the only move 35.Kh4! (35.Kg5 Rc5+) the win is achieved as follows: 35...Qxf6+ 36.Kh3 Qb2! 37.Kh4! Kh6! 38.Rh8+! Kg7!”


Go ahead and laugh, but this is just not true! You don't believe me?


If we extend the variation with the five exclamation marks for one more move – 39.Qd8! – the draw becomes obvious: 39...Rc8 40.Rg8+ Kh7 41.Qxc8 Qxh2+ 42.Kg5 Qxg3+ 43.Kf6 Qxf4+ 44.Ke7 Qe4+. Or 39..Qf6+ 40.Qxf6+ Kxf6 41.Rf8+ Ke7 42.Ra8 Rxh2+ 43.Kg5 Rg2 44.Rxa7, etc.


What's more, the alternative move 35.Kg5, which must seemingly be rejected in horror due to the “fatal” check 35...Rc5+, is in fact winning for White:

36.f5 Rxf5+ 37.Qxf5!! (and not 37.Kh4 Qxh2 mate) 37...gxf5 38.Rd7+ Kg8 39.Kg6! and it suddenly becomes clear that Black can avoid immediate mate only by giving up his queen! (By the way, I was very proud of my discoveries until I found out they had already been made in 2002 by the trainer L. Veretnovy from Krasnoyarsk.)

The most striking thing of all is that Alekhine's variation is doubly wrong. In the first place, as we have seen, it leads not to a win, but to a loss! In the second place, after 32.Qd3+ g6 33.Kg4 f5+, Levenfish in annotating the game in the Newsletter of the Petrograd Commune had already indicated a simple drawing line: 34.Kf3! Rc3 35.Rd7+ Kh8 36.Rd8+ with perpetual check. However, he too thought that 34.exf6 would lose on account of 34...h5+.

32...Rxh2

“Such a pity!” is Levenfish's lament in his book Selected Games and Reminiscences. “By continuing 32...h5+ 33.Kxh5 (33.Kxg5 f6+) 33...Rxh2+ 34.Kg4 Qg2 35.Qd3+ (if 35.Rd7 then 35...Rh6!) 35...g6 36.Rd7 (or 36.Kg5 Kg7 37.Rd7 Rh5+ 38.Kg4 Rh4+! and mates) 36...Kh6! 37.Rxf7 Rh4+! 38.Kxh4 Qh2+ 39.Kg4 Qh5#, Black would have brought this combative game to a beautiful conclusion.”

Indeed, it's a beautiful conclusion. Why then did Alekhine, in citing the alternative variation 32...g6 33.Rh8+! Kxh8 34.Qd8+ Kh7 35.Qe7! with a draw, restrict himself to the laconic comment, “If 32...h5+ then simply 33.Kxh5!” Was he mistaken yet again?

No, this time his analysis was accurate. It turns out that White is not obliged to play 36.Rd7? (also bad is 36.Rf8? Qh3+ 37.Kf3 Rg2 38.Rxf7+ Kh6 39.Ke4 Rxg3). One of Levenfish's parenthetical variations in fact leads to a draw: 36.Kg5! Kg7, and as before not 37.Rd7? but 37.Qa3! Rh5+ 38.Kg4 Qd2+ (or 38...Kh7 39.Rh8+ Kxh8 40.Qf8+ Kh7 41.Qxf7+ Kh6 42.Qf8+) 39.Qf3 Qh2 40.Qa3 with a repetition of moves.

33.Qd3+ g6 34.Rd7! Kg7

If 34...Rh4+? then 35.Kf3!

35.Rxf7+

Draw.

With this we conclude our extract from Voronkov's book.

Bird vs Chigorin, Vienna 1882, Part Two


Last time we presented the game Bird – Chigorin, Vienna 1882, with analysis by Solomon Lipschutz and supplemental comments by Mikhail Chigorin. Today we present the same game with annotations from the modern era by the Soviet grandmaster Evgeny Vasyukov, extracted from his 1973 book Mikhail Chigorin, co-authored with Alexander Narkevich and Alexander Nikitin.

Bird – Chigorin, Vienna 1882 Two Knights Defence C59

1.e4 e5 2.Nf3 Nc6 3.Bc4 Nf6 4.Ng5 d5 5.exd5 Na5 6.Bb5+ c6 7.dxc6 bxc6 8.Be2 h6 9.Nf3 e4 10.Ne5 Qc7 11.Ng4

This retreat is not considered the strongest. Instead of making the useful developing move 11.d4 or reinforcing his central position with 11.f4, White trades off his only active piece.

11...Bxg4 12.Bxg4 Bd6

A standard move in this system, and strong enough here because it stops White from castling. But 70 years after this game was played, one of our best masters of attack Rashid Nezhmetdinov suggested an even stronger plan in which both h2 and f2 are subjected to attack: 12...Bc5! 13.Be2 Rd8 14.c3 Nb7 15.0-0 h5! 16.d4 exd3 17.Bxd3 Ng4! The game Ciocaltea – Nezhmetdinov, Bucharest 1954, continued 18.Qe2+ Kf8 19.g3 Qd7 20.Be4 h4 21.Bf4 Nxh2! and Black won shortly.

13.h3

In a 1953 training game against Smyslov, Bronstein retreated his bishop to h3 with the idea of relocating it to g2. However this manoeuvre requires a lot of time and allows Black to increase the pressure: 13.Bh3 0-0 14.g3 Nd5 15.0-0 Rae8 16.d3 e3.

13...O-O 14.Nc3

Steinitz considered that 14.b3 was necessary here, hindering the transfer of Black's knight to the centre. But this move, which does nothing to aid White's development, can hardly change the nature of the struggle. Black would develop strong pressure on the central files, for example: 14...Be5 15.Nc3 Rad8 16.Bb2 e3! 17.fxe3 Bxc3 18.Bxc3 Ne4!

14...Nc4 15.b3?
White is playing the opening rather carelessly. Developing the bishop on b2 is a mistaken idea. The main events are bound to take place over on the kingside, where Black has directed all of his pieces. Therefore the following plan of development deserved attention: 15.Be2 Ne5 16.d3! (16.d4 Ng6 17.0-0 Nh4) 16...exd3 17.cxd3 Rad8 18.0-0. Of course, even here Black's edge in development would guarantee him the initiative, but it would be far easier for White to defend than in the game.

15...Ne5 16.Bb2 Rfe8 17.O-O

It is too late for White to retreat his bishop (17.Be2 Nf3+! 18.Kf1 Nh4) so he hurries to get his king out of the centre. However, this loses a pawn.

17...Nexg4 18.hxg4 Qd7 19.Qe2

Defending the pawn on g4 would lead to the creation of other weaknesses: 19.f3 Bc5+ 20.Kh1 Rad8 21.Na4 Bd4!

19...Nxg4



Diagram

A critical moment. With material being equal White can hardly count upon a successful defence. But can he capture the pawn on e4? This makes use of the fact that after 20.Nxe4 Black cannot play 20...f5 because of 21.Qc4+. The risk appears to be substantial. The pin on the knight is very unpleasant and enables Black to obtain the advantage in two ways: 20.Nxe4 Bh2+ 21.Kh1 Bc7 22.f3 f5 23.Qc4+ Kh8 24.Nf2! Qd6 (for example, 25.Nxg4 fxg4 26.f4 Qg6) or 20...Qf5 21.f3 (sacrificing the queen does not work: 21.Nxd6 Qh5 22.Qxg4 Qxg4 23.Nxe8 Rxe8 24.Rfe1 Rxe1+ 25.Rxe1 Qf5 26.d3 Qa5!) 21...Qh5! 22.fxg4 Qh2+ 23.Kf2 Qf4+ 24.Kg1 Rxe4 25.Rxf4 Rxe2 26.Rf2 Re4 (Chigorin). Nevertheless, if White wants to choose the least of evils, he should try to find salvation in this endgame. In declining to take the pawn he dooms himself to a prospectless defence.

20.g3 Qf5 21.Kg2 Re6 22.Rae1

Exchanging the e-pawn with 22.f3 exf3+ (22...Qe5 23.f4!) 23.Qxf3 does not save White from the attack after 23...Qg6!

22...Rae8 23.Rh1 h5!

Winning the exchange with 23...Qxf3+ 24.Qxf3 exf3+ 25.Kxf3 Rxe1 26.Rxe1 Rxe1 27.Kxg4 Be5 would also guarantee Black victory, but it would take much longer. He still has ways of strengthening the attack, and Chigorin decides to press on with them. The threat now is 24...Qf3+, winning a rook since the knight on g4 is defended.

24.Ref1 Qg6! 25.Nd1

Diagram

Black has apparently retreated his queen in order to make way for his f-pawn, and here in fact 25...f5 26.Ne3 f4 would also give him an irresistible attack. But Chigorin demonstrates an unexpected combinative possibility.

25...e3!

Now it becomes clear that the square g3 cannot be defended against intrusion by the Black queen, since after 26.Nxe3 Nxe3+ 27.dxe3 there follows 27...Rxe3 28.Qxh5 Rxg3+ and mate on the following move.

26.Bd4 Nxf2 27.Rxf2 Qxg3+ 28.Kf1 exf2 29.Ne3 c5 30.Bc3 Rxe3! 31.dxe3 Rxe3 32.Qd1 h4 33.Bd2 h3!

White resigned (0-1).

Here we conclude our extract from Vasyukov's 1973 analysis as well as our two-part excursion into master chess of the late 19th century.

Bird vs Chigorin, Vienna 1882, Part One


The Russian master Mikhail Chigorin compiled an amazing record on the Black side of the Two Knights Defence. Over the course of his career he employed this counterattacking system in a total of 17 games, mostly against the world's elite. He scored 13 wins, 1 draw, and only 3 losses for a winning percentage of 79%, far in excess of the standard 45% that Black can expect from the starting position. In particular his great rival Wilhelm Steinitz was bested by a score of four games to one.

Why was Chigorin so successful with the Two Knights Defence? In the first place, he was a fine attacking player with a strikingly modern feel for the initiative and the importance of piece activity. He was also aided by the generally low reputation enjoyed by the Two Knights Defence in those days. This reputation was based in large part on the writings of his rival Steinitz, who famously believed that “a pawn is worth a little trouble.” In particular, Steinitz believed that Black did not have the right to sacrifice a pawn in the opening. For his part, Chigorin didn't care what Steinitz (or anyone else) thought was right or wrong. He saw the assets in Black's position and worked hard to make them count.

Today we present a lesser-known but particularly fine example of Chigorin's play in the Two Knights Defence – his game with the English master Henry Bird from the great Vienna tournament of 1882. This event, by the way, was won by Steinitz after a playoff match with Simon Winawer. Chigorin finished 12th and Bird 15th out of 18 participants.

The Bird-Chigorin encounter did not go unnoticed by the contemporary chess press. It appeared in the Russian magazine Shakhmatny Vestnik in 1885, and later in The Chess-Player's Manual by Gossip and Lipschutz (1888). It also came to the attention of Wilhelm Steinitz, who included it in Part 1 of his two-volume opus The Modern Chess Instructor (1889).

While preparing his 1950 commemorative book on Chigorin, Nikolai Grekov gained access to the Russian master's archives, including a copy of The Modern Chess Instructor. There he found some pencilled comments to the Bird-Chigorin game in which Chigorin expressed disdain for aspects of Steinitz's analysis. Needless to say, these comments were included in Grekov's book in order to demonstrate that, even in analysis, Chigorin could hold his own against his rival.

In preparing this article I had occasion to refer directly to The Modern Chess Instructor, where I found the following caveat by Steinitz, which had been conveniently omitted from Grekov's book: “Our notes to this game are chiefly quoted from the Appendix to Gossip's Manual by S. Lipschutz.” Chigorin would have known this, so his disdain would have been largely directed at Lipschutz instead of Steinitz. However, Steinitz was ultimately responsible for the content of his book. In our article today, the comments by Steinitz/Lipschutz have been slightly edited for clarity. Chigorin's pencilled comments appear in italics, and there are two further comments of his from Shakhmatny Vestnik.

Bird-Chigorin, Vienna 1882 Two Knights Defence C59

1.e4 e5 2.Nf3 Nc6 3.Bc4 Nf6 4.Ng5 d5 5.exd5 Na5 6.Bb5+ c6 7.dxc6 bxc6 8.Be2 h6 9.Nf3 e4 10.Ne5 Qc7 11.Ng4

11.d4 exd3 (and if one does not capture en passant?) 12.Nxd3 Bd6 13.Nd2 followed by Nf3 would give White an excellent game with a pawn ahead. For should Black then attempt 13...Bxh2, then would follow 14.g3 Bxg3 15.fxg3 Qxg3+ 16.Nf2 and should win.

11...Bxg4 12.Bxg4 Bd6 13.h3 O-O 14.Nc3

White would have done better first to prevent the entrance of the hostile knight by 14.b3. Rubbish; then comes 14...Be5 15.Nc3 e3 16.fxe3 Bxc3, etc.

14...Nc4 15.b3 Ne5 16.Bb2 Rfe8 17.O-O

17.Be2 Nd3+ (or 17...Nf3+ 18.Kf1, etc.) (Just so: “et cetera.” And how will things turn out for White after 18...Nh4?) 18.cxd3 exd3 19.0-0 was far more favourable for White.

17...Nexg4 18.hxg4 Qd7 19.Qe2

If 19.f3 Bc5+ 20.Kh1 Qe7 with a winning attack.

19...Nxg4 20.g3

20.Nxe4 Qf5 21.f3 Qh5 22.fxg4 Qh2+ 23.Kf2 Qf4+ (or 23...Qh4+ 24.g3 Bxg3+ 25.Kg2 and should win; if here 24...Qh2+ 25.Kf3 Qxe2+ 26.Kxe2 Rxe4+ 27.Kf3 with a pawn ahead) 24.Kg1 was by far better play, for Black's best plan would be now to draw by perpetual check. What on earth for? After 24...Rxe4 25.Rxf4 Rxe2 26.Rf2 Re4! Black's position is better – perhaps significantly so.

20...Qf5 21.Kg2 Re6 22.Rae1

Ill-judged. 22.Rh1 followed by 23.Raf1 was much better.

22...Rae8 23.Rh1 h5!

Black could win the exchange by playing 23...Qf3+ but after 24.Qxf3 (24.Kg1 Bxg3!) exf3+ 25.Kxf3 Rxe1 26.Rxe1 Rxe1 27.Kxg4 play would continue for quite some time. Now, having defended his knight, Black threatens 24...Qf3+ (Chigorin, Shakhmatny Vestnik, 1885).

24.Ref1 Qg6 25.Nd1

Premature. 25.Rh3 was necessary for the defence. Black was threatening 25...e3 26.dxe3 Nxe3 (Chigorin, Shakhmatny Vestnik, 1885).

(diagram)

25...e3!

A real master coup which forces the victory in elegant style.

26.Bd4

If 26.dxe3 Nxe3+ 27.Nxe3 Rxe3 threatening 28...Rxg3+ and wins.

26...Nxf2 27.Rxf2 Qxg3+ 28.Kf1 exf2 29.Ne3 c5 30.Bc3 Rxe3

Beautiful play, which finishes off the quickest way.

31.dxe3 Rxe3 32.Qd1 h4

32...Rxc3 followed by 33...Kf8 (if White reply 33.Qxh5) was also good enough.

33.Bd2 h3

White resigned (0-1)

Next time we will present this game with more modern annotations. Stay tuned!

Alonso vs Suttles, Gijon 1965



Here is an early tournament game by GM Duncan Suttles, which remained undiscovered at the time of publication of Chess on the Edge, the monumental three-volume work by FM Bruce Harper and GM Yasser Seirawan.

Jose Ramon Alonso - Duncan Suttles, Gijon 1965 Modern Defence [A42]

1.d4 g6 2.c4 Bg7 3.Nc3 d6 4.e4 Nc6 5.Be3 e5 6.Nge2 Nh6 7.d5 Ne7 8.f3 f5 9.Qd2 Nf7 10.h4

White has no real attacking prospects on the kingside, so perhaps he is merely looking for complications. If so, he has met a worthy associate in Mr Suttles!

10...c5

Radically forestalling a possible c4-c5 pawn break by White.

11.Ng1 h5 12.Nh3 f4 13.Bf2 Bh6 14.Bd3 a6 15.Ke2

Black is not well-placed for a queenside attack, so White should consider castling long, perhaps following up with Rdg1 and g2-g3!?

15...Bd7 16.a4 Qa5 17.b4 cxb4 18.Na2 Rc8 19.Rhb1 Bxh3 20.gxh3 Qxa4

With White's king still in the centre, Black should not be thinking about exchanging queens.

21.Rxb4?!

Stronger was 21.Qxb4! with queenside pressure for White.

21...Qd7 22.Rab1 Nd8

Here Black could make White's life difficult with 22...Qxh3! and if 23.Rxb7 then 23...g5!

23.Rb6 Rc7 24.c5 Nc8 25.cxd6 Nxd6 26.Qb2 N8f7 27.Rg1 Rg8 28.Nc3 Bf8 29.Qb3 Be7

Here too 29...Qxh3 would have posed problems for White.

30.Na4 (diagram) 30...Qxh3!?

But now it seems better to play 30...Qc8 and if 31.Qb1 then simply 31...Kf8 with advantage to Black.

31.Nc5 Rxc5?

This looks like a time trouble error. 31...Bxh4! was still good for Black. Now things turn around dramatically.

32.Bxc5 Bxh4 33.Rxb7 Nxb7 34.Qxb7 Nd8 35.Qh7! Rf8 36.Qxg6+ Rf7 37.Bxa6 Qh2+ 38.Rg2 1-0

In many ways a typical Suttles game: strategically deep, but tactically... not so deep!

Ljubojevic vs Beliavsky, Tilburg 1981
















The former Soviet champion Alexander Beliavsky scored a memorable victory in the Tilburg 1981 international tournament. The field comprised most of the world's elite, including future world champion Garry Kasparov as well as the former champions Boris Spassky and Tigran Petrosian. In fact, the only leading players who were not present at Tilburg were Anatoly Karpov and Viktor Korchnoi. They were otherwise occupied in a world title match in Italy.

No one wins a tournament of this calibre without some luck. In particular Beliavsky had to survive a mutual time scramble in his game with Ljubomir Ljubojevic before finally achieving a draw. Curiously, Beliavsky's annotations to this game in Informant 32 leave a few unanswered questions. Today we will look at the exciting conclusion of this game, supplementing Beliavsky's annotations with a few extracts from my notebook.

In the first diagrammed position, the time control at move 40 is looming, and things are complicated. Beliavsky as Black has just played 35...Rf6, threatening 36...Bf2. Ljubojevic correctly decides to bail out by offering the exchange of queens.


36.Qg3 Qxg3 37.Nxg3 Nxh3!?


A clever psychological blow. Whenever the opponent puts a piece en prise, it is natural to believe that taking it must be wrong...

38.Rf1?

White is defending comfortably after 38.gxh3 Rxg3 39.Bg4! Rf2 40.Rxb7 Bc5 41.b4! and now Black has nothing better than 41...Rgg2 and a draw by repetition (Beliavsky).

38...Nf2+ 39.Kh2 (second diagram) 39...d5?


Beliavsky gave 39...Rf4! (threatening 40.Rxb7 Rh4+ 41.Kg1 Nh3+and wins) 40.Nf5 Rg5 41.Bxf7(?) and now 41...Rgxf5 wins immediately since the bishop is also attacked. However, White can defend more stubbornly with 41.Be2! Rgxf5 42.g3! Rg4!? 43.Kg2 Rxa5 44.Rxf2! Rgg5 45.Rxf7 although Black still has the advantage after 45...b5.

More convincing is 39...Rg5! If 40.Rxb7 then 40...Bd4 intending 41...Be5, while if 40.Be2 then 40...Rfg6, with a decisive attack on White's knight in both cases.

Beliavsky gave 39...d5 the question mark. But it might deserve two because it does more than throw away the win.

40.Rxb7?

Fate has given Ljubojevic a chance of his own. He can win the exchange with 40.e5! since the attacked rook is short of squares. Black can recover the material with a counterattack: 40...Bb8! 41.exf6 Ne4 42.Bxf7 Rg4 but after 43.Rxb7 Rh4+ 44.Kg1 Bxg3 45.Rf3 Bh2+ 46.Kf1 Nd2+ 47.Ke2 Nxf3 48.gxf3 White's a-pawn is extremely dangerous and should cost Black the game.

40...Bd4?


The final mistake, after which the game peters out to a draw. Beliavsky gave 40...Bc5 41.Rxf7 Rxf7 42.Bxf7 Rg7 43.exd5 Bd6 44.Be6 Bxg3+ 45.Kg1 cxd5 46.Rxf2 Bxf2+ 47.Kxf2 Rb7 with a slight edge to Black, but for some he reason he failed to notice the defensive shot 40...Bb8!, winning material. White is practically forced to play 41.Rxb8 Rxb8 42.exd5 cxd5 43.a6 Rxb2 and can make things difficult with the further 44.Ra1 Rb8 45.a7 but it is hard to believe that Black is not winning after 45...Ra8.

After the text move 40...Bd4, Ljubojevic played the simple


41.Rxf7

forcing off a pair of rooks. The game ended in a draw a few moves later.

Capablanca on Moscow 1925


The following interview with J.R. Capablanca was conducted by a Berlin newspaper in 1925. The World Champion had stopped while en route from the recently-concluded Moscow tournament.

...We were received in the capital of the Soviet Union with genuine Russian hospitality, straight from the heart, and the Soviet Government did everything to make the participants' visit to their country as pleasant as possible. During our entire stay in Moscow we were the guests of the government, and were at all times treated with great courtesy. For example, we were freed from all hotel expenses, even the most trifling ones, and accommodation in Moscow as well as the train trip to Russia and back was paid for by the Soviet Government on behalf of all the players.

All of the tournament participants were pleasantly surprised by the extraordinary enthusiasm for chess displayed by all levels of the Russian population. As is well-known, the competition was held in the magnificent Hotel Меtropol, and with such a weight of spectators that the enormous tournament hall appeared to be too small. It was constantly overflowing, and was made to contain three and even four times its capacity, while the tickets for each round were were sold out days in advance. For me this is an indicator of the Russians' genuine enthusiasm for chess, which one could even describe as a passion.

The Soviet Government gives chess a important place in its system. By way of illustration, a formal reception for the players was arranged by Mr Krylenko, the general public prosecutor of the USSR. Mr Krylenko, along with fulfilling his important duties in the field of justice, is also the head of the Chess Section for the entire Soviet Union.

Bogoljubow's victory was met with the greatest enthusiasm by his fellow countrymen. A crowd followed him through the streets, and everywhere he went he was met with deafening applause.

As to the techniques and methods of the Moscow tournament, I will refrain for the time being from making any judgements in this respect. I can only express the view that this tournament has confirmed once again the old assertion that in an international competition there can be no absolute, mathematical certainty as to its outcome. Even where the greatest players are taking part, there is still the possibility that a third party will overtake them. This is what happened in Moscow. In general, the strength of all the participants was well-known to everyone, and everyone had a full opportunity to display their abilities. In my case, I had already had the chance to cross swords with Bogoljubow, in London [1922] and New York [1924].

In any case, the young chessplayers of the USSR survived their baptism of fire in Moscow in excellent fashion, and showed that they are worthy of the hopes placed upon them for the future.

Torre, the youngest participant in Moscow, is improving from tournament to tournament right before one's eyes.

It is still not clear whether I will be able to play in the Semmering International Tournament, which is set to take place in March, 1926. But this tournament also promises to be very interesting, with such players as Alekhine and Tartakover in the lists...

Levenfish on Moscow 1925



Today we offer another extract from Grigory Levenfish's 1967 book Selected Games and Reminiscences.

...The Moscow International Tournament was set to begin on November 9th. The organizing committee did not repeat the mistakes made in connection with the St Petersburg tournament of 1914. The preparatory work had already begun in April, and the entry consisted of 10 Soviet and 11 foreign masters. The committee managed to secure the participation of the world champion Capablanca, the ex-champion Lasker, as well as Rubinstein, Reti, Marshall, Tartakower, and Spielmann, so the entry was truly a strong one.

The Fountain Hall of the Hotel Metropol was chosen as the playing site. This hall is not directly connected to the outside atmosphere. The ventilation system had been designed for approximately 200 restaurant patrons, but during the tournament the number of spectators approached 1,000. The fountain only made the situation worse, and the “climate” can only be described as damp and tropical. Capablanca, who was used to the heat of Havana, told me he would not object if the participants were allowed to wear bathing costumes during play. The order was given to make the ventilation system more powerful, but that was going to take more than a week, and meanwhile the players had to tolerate the heat and the noise. Rubinstein and Spielmann in particular had trouble adapting to the conditions. On the other hand Bogoljubow felt fine, being the picture of health to start with. In the second half of the tournament I managed to acclimatise myself to some extent, but it was already too late. I finished the tournament in 15th place, winning two prizes: one for the best result over the last five rounds, and the other for the best score against the foreign players.

I was amazed by Lasker's adaptability. At the age of 57 he played the whole tournament with great energy and ended up in second place.

All in all the tournament went extremely well. Every day a huge crowd of people would surround the booking office in search of tickets, and the mounted police had to be called in to maintain order.

In the end Bogoljubow achieved the very best result of his chess career. For some time he considered it necessary to go along with Soviet chess organisers, even though he had been living in Triberg continuously since 1914. But when the All-Union Chess Section suggested that Bogoljubow refrain from competing in certain events abroad, he refused to comply and was excluded from the ranks of Soviet chessplayers.

Earlier I referred to the extraordinary interest in the tournament shown by the public. In spite of the high admission price it was not easy to find tickets. However, among the spectators one could spot a number of flashily-dressed women – apparently the wives of new capitalists – who did not understand anything about chess, but who thought it important to make an appearance at such a popular and well-attended gathering. The hot-blooded Capablanca was especially popular with these women, and after the tournament he was able to relate more than one adventure reminiscent of The Decameron...

Levenfish on St Petersburg 1914


We offer without commentary an extract from Grigory Levenfish's 1967 book Selected Games and Reminiscences. Grandmaster Levenfish died in 1961 and his memoirs were published posthumously.

...The organizing committee managed to attract a very strong complement of grandmasters. The first to accept his invitation was Lasker, the World Champion, mainly because he was offered a special appearance fee. Next were the two challengers for the chess crown: Capablanca and Rubinstein. Then Tarrasch, Marshall, Janowski, Bernstein, the two winners of the preliminary masters tournament Alekhine and Nimzowitsch, and finally the veterans Blackburne and Gunsberg. Unfortunately, Duras, Maroczy and Schlechter declined their invitations. There were to be five prizes awarded.

Would the 45-year-old Lasker be able to compete with the young Capablanca, who had astonished all of Europe with his successes, and with Rubinstein, the winner of a series of strong international tournaments? These were the main questions stirring the interest of chessplayers throughout the world.

I assisted the organizing committee in finding accommodation for the players. Rubinstein arrived a week before the tournament and was given quarters in the European Hotel. After just two days he expressed dissatisfaction with his room, saying he was disturbed by the noise of the elevator. One of the Committee members then offered Rubinstein the choice of any room in his apartment. There were six rooms in all, and the host was a bachelor who lived alone. Rubinstein duly moved there, but again he was unsatisfied. He found the apartment so quiet as to be oppressive, and he had to be transferred back to the hotel. It was clear to me that Akiba's nervous system had become weakened, and this did not bode well for the future.

The Moscow lawyer O.S. Bernstein had been Rubinstein's main competitor in the Vilna tournament [1912] and in his playing strength he did not give anything away to his rivals. But Bernstein had not spent much time on chess and his theoretical preparation was manifestly inadequate. He lost the decisive game with Tarrasch right in the opening, and with White at that.

The Riga player Nimzowitsch had achieved a major success in the San Sebastian tournament of 1912, where he was in the running for first prize right up to the last round.

No one was placing any special hopes on Alekhine, as this was his first opportunity to cross swords with world-class grandmasters. In fact he achieved only a modest result against Lasker and Capablanca, but he played with great success against the other grandmasters. As it turned out, Alekhine was the only player from Russia in the group of finalists.

The play of Capablanca made an unforgettable impression on me. He too was making his first appearance in such a strong tournament, but even so he appeared to be playing quite effortlessly. In the preliminary rounds he won game after game. He played exceptionally well in his first encounter with Lasker. An amazing pawn sacrifice led to the win of material, and it was only a very deep defence that saved Lasker from defeat.

At this tournament I saw Tarrasch for the first time. After he lost his match to Lasker, his native arrogance had been knocked down somewhat; nevertheless his impertinent and self-assured manner made an unpleasant impression. His service to the cause of popularising chess is indisputable. Two whole generations have studied his books, and it is no coincidence that he was given the title Praeceptor Germaniae. His strategy was dogmatic, but his tactics were excellent. His game against Nimzowitsch took the first prize for brilliancy.

The Russian emigre Janowski had moved to France and was living in Paris. He was certainly the most elegant of the participants, both in appearance and in his manner of play. During the period from 1900 to 1907 he achieved his greatest successes; but his matches with Lasker and Marshall showed conclusively that his talent had declined. Janowski had become too enamoured with games of chance, and did not have the time or patience for chess.

Marshall's appearance did not correspond with one's image of the typical Yankee. It is possible that a dash of Indian blood was showing its traces. His credo was the attack, which he conducted with great energy and patience, often overpowering weaker opponents. In tournaments of mixed strength Marshall won a number of high prizes, but in grandmaster tournaments and especially in matches against the strongest players, where his ingenious combinations were seen off by sturdy defence, he was not able to achieve much success.

Blackburne, the “patriarch” of the tournament, possessed a similar style. It was no accident that in his heyday his comrades-in-arms had nicknamed him “the Black Death.” Blackburne won a number of prizes in tournaments, but was defeated by lopsided scores in matches against Lasker, Steinitz, and Zukertort. Despite his age, Blackburne fought hard for every point. He defeated Nimzowitsch brilliantly, and in an inferior endgame he outwitted Rubinstein himself and achieved a draw.

In the 1890s Gunsberg had a reputation as one of the strongest chessplayers in the world. He drew a match with Chigorin and lost narrowly to Steinitz after a dour struggle. But an extended break from practical play had had a sharply telling effect on his mastery, and he lost games without a struggle. One must remark upon Gunsberg's patience. It is not easy to endure a series of losses, but Gunsberg remained unruffled and politely congratulated each one who defeated him.

The sensation of the tournament was the complete failure of Rubinstein. In terms of quality, his play was quite unrecognisable. Against all expectations, Rubinstein did not qualify for the final group of five players. Capablanca took the lead easily and finished the first stage with 8 points out of 10 games. There was a bitter struggle for the remaining places. In the eighth round Lasker lost somewhat fortuitously to Bernstein, and in the ninth round he was on the edge of defeat against Tarrasch. The fate of Rubinstein could easily have overtaken Lasker as well. Tarrasch started a joke: while the five qualifiers were playing the final, Rubinstein and Lasker were going to play a match for the World Championship. But in the final rounds Lasker improved his standing, and together with Tarrasch, he finished in second place with 6½ points. The fourth and fifth places were shared by Alekhine and Marshall with 6 points.

In the final stage of the tournament Lasker demonstrated exceptional mastery. It is enough to recall that in 8 games against Capablanca, Alekhine, Tarrasch, and Marshall, he scored 7 (!) points and captured first prize. Capablanca was half a point back. The big surprise was Alekhine's third-place finish. It had become obvious that Alekhine was moving confidently into the first rank of grandmasters.

The tournament produced many fine specimens of chess artistry, and one can only regret that so far no collection of games from this first-class event has been published in Russian...

Petrosian vs Spassky, Leningrad 1960


The tenth world champion Boris Spassky has written very little about chess. No game collection -- just some contributions to the Santa Monica 1966 tournament book, a contribution to a book on the Sicilian Najdorf, a few articles in obscure Soviet magazines, and that's about it. In this context he once described himself as a “lazy Russian bear.”

While browsing through the 1960 Soviet Yearbook the other day, I came across a rare set of annotations by Spassky, these to his game with Tigran Petrosian from the 27th USSR Championship in Leningrad. The lazy Russian bear had come out of hibernation!

Curiously, this is one of only three decisive games between Spassky and Petrosian from tournament play. Petrosian won again at the 1971 Alekhine Memorial in Moscow, and Spassky took a measure of revenge at the 1975 USSR Team Championship in Riga.

From now on the comments are by Boris Spassky.

Petrosian,T - Spassky,B
27th USSR Championship
Leningrad 1960


Before this game the two opponents had met eight times and even though most of the games had featured a sharp struggle, each one had ended in a draw. This time both players again went for a win and finally managed to break out of the “vicious circle” of draws.

1.d4 Nf6 2.Nf3 g6 3.c4 Bg7 4.Nc3 0–0 5.e4 d6 6.Be2 e5 7.0–0

This was a bit of a surprise for me. In this position Petrosian usually plays 7.d5.

7...Nbd7 8.Re1 c6 9.d5

With this move White closes the centre and also significantly reduces the activity of his opponent's dark-squared bishop. This advance is usually connected with a pawn storm on the queenside. At the same time one should also note the negative aspects of the move. Because Black now obtains a comfortable post for his knight – the square c5 – and because the pawn tension around the square e5 has been released, Black can now advantageously prepare the advance f7-f5.

9...Nc5 10.Bf1 a5 11.Bg5

The beginning of a definite plan. By pinning the Black knight, White prevents his opponent from preparing the advance f7-f5. At the same time he intends to transfer his own knight from f3 to d2 and later to b3. And if Black drives the enemy bishop to g3 by playing h7-h6 and g6-g5, then White will be able to bring it back into play after f2-f3. However, in the present situation this plan does not turn out successfully because of Black's 13th move.

11...h6 12.Bh4 g5 13.Bg3 Bg4! 14.Re3

White prepares to move his queen out of the pin. If he does this immediately by playing, say, 14.Qc2, then 14...Bxf3 15.gxf3 is very unpleasant for White because the bishop on g3 is left out of play. However, the move in the game involves a loss of time and with his 14th move Black begins an active plan of attack against e4, the stronghold of White's position.

14...b5! 15.dxc6

The strongest continuation. After 15.cxb5 cxd5 16.Nxd5 (if 16.exd5 then 16...e4, etc.) 16...Nfxe4 Black obtains good play.

15...b4 16.Nb5

16.Nd5 is also not dangerous for Black because of 16...Nfxe4 17.c7 Qe8 with good play.

16...Nfxe4 (diagram)

A very complicated position has arisen, one that is not easy to assess. White has a passed c-pawn and a strong knight on b5 threatening the backward pawn on d6. Black for his part has compensation in the form of a pawn majority in the centre and the strong position of his minor pieces. In addition White has to reckon with the advance of the enemy f-pawn.

17.c7

It was better to play 17.Bd3 immediately, and if 17...f5 then to sacrifice the exchange with 18.Bxe4 fxe4 19.Rxe4 Nxe4 20.Qd5 followed by 21.Qxe4 with approximately equal chances due the strong position of the knight on b5 and the dangerous passed c-pawn.

17...Qe7?

A mistake, relinquishing Black's advantage. Correct was 17...Qd7! If White replies 18.Bd3 then there follows 18...f5. In this situation the exchange sacrifice is not good for White; for example 19.Bxe4 19...fxe4 20.Rxe4 Nxe4 21.Qd5+ Be6 22.Qxe4 d5! with advantage. Instead of 20.Rxe4 White can play 20.h3 but even then 20...Be6 (20...Bh5 21.Nxe5!) 21.Nd2 d5 would give Black the better game.

If White does not take on e4 but plays 19.Bc2, then 19...Nf6 is possible. In view of the threat of f5-f4 White would have to sacrifice a piece with 20.Qxd6 Qxd6 21.Nxd6. However, after 21...e4 and 22…f4 Black would get the advantage.

18.Bd3 Nxg3

The exchange of an active knight for a bishop that has no prospects appears to be illogical. On the other hand it is not clear how Black can fight for an advantage. For example, if 18...f5 then 19.Bxe4 fxe4 20.Rxe4 Nxe4 21.Qd5+ gives White satisfactory play. Or 18...Nf6 19.Nxd6! and the queen cannot take the knight because of 20.Bh7+.

With the move in the game I marked out a plan that was based on an incorrect assessment of the position.

19.hxg3 f5

Black overestimates the strength of his centre pawns. After the game Petrosian suggested 19...Rac8 followed by 20...Rxc7. In that case Black would have a pawn and two active bishops for the exchange.

20.Bc2!

Consolidating White's advantage. The attack on the d6-pawn is very unpleasant. What should Black do now? If 20...e4 then 21.Qd5+ Kh8 22.Nfd4 with the threat of 23.f3 and White stands better. Or 20...Ra6 21.Qd5+ Kh8 22.Nh2 f4 (22...Bh5 23.Bxf5!) 23.Nxg4 fxe3 24.Nxe3 with an excellent position for the sacrificed exchange.

20...f4 21.gxf4 gxf4 22.Re1 Ra6 23.Be4 h5?

This “active” move only worsens Black's position. It was time to think about how to get rid of the enemy pawn on c7. Deserving attention was 23...Bd7 with the threat of Bxb5 25.cxb5 Rb6. In that case Black could successfully carry on the struggle.

24.Qc2 Qf6 25.Nd2 h4

The advance of this pawn holds absolutely no danger for White.

26.f3 Bc8 27.Bd5+ Kh8 28.Ne4

White has established a blockade on the central squares, and as a result Black's forces are completely paralysed.

28...Qh6

Still laying some hopes on the h-pawn.

29.Re2 h3 30.gxh3 Rf5 31.Rh2 a4 32.h4 b3 33.axb3 axb3 34.Qd1 Rxa1 35.Qxa1 Black resigns (1-0)

White threatens 36.Nexd6. Black can only parry this threat with 35...Nxe4. Then 36.Bxe4 Rf8 37.Qd1 puts him in a completely helpless position.

Defensive tactics


Here is a late middlegame position of a type that arises so often in mixed tournaments. One side clearly has the initiative because of greater piece activity, but a decisive tactic has not quite materialised. In this particular case both players have pawn weaknesses but Black is on move and should be thinking about putting White to the test. But what's the best way forward?

This was the challenge facing Efim Geller (Black) in his game with Yuri Balashov from the 1969 Soviet Championship in Moscow. If it were White's turn to play, he would oppose rooks with 1.Re1 and take a large step towards neutralising Black's initiative. Geller understood this very well and was ready with an active idea:

1...Re2

The attack on the g-pawn makes things difficult for White, as the following variations show:

a) 2.Be1 Rxc2+ 3.Kxc2 Rxa2+ followed by 4...Rxg2 and Black wins easily;

b) 2.Rg1 Bd4 3.Re1 Rxg2, etc.;

c) 2.g3 Rf2 3.f4 (3.Re1 Rxf3) 3...b5 4.Re1 h5! 5.Re7 Rf1+! 6.Re1 Rxe1+ 7.Bxe1 h4 8.Kb1 ( 8.Rc5 Rxa2 9.Rxf5 Ra1+ 10.Kd2 b4–+) 8...Re4 9.Bd2 h3 and White is in continuing difficulties.

But there is a hidden resource that saves the game for White, and Balashov finds it:

2.Re1!! Rxg2 3.Rc8+ Kf7 4.Rc7+ Kf8

Unfortunately for Geller, Black can no longer play for a win. If 4...Kg6 5.Re6+ Kh5 and now White has the surprise shot 6.Rxg7!, which wins immediately because 6...Rxg7 runs into 7.Rh6#.

After the further moves

5.Rc8+ Kf7 6.Rc7+

the players agreed to a draw.

In the starting position Black has two other tries:

a) 1....Kf7 2.Re1 Rxe1+ 3.Bxe1 Be5 4.g3 f4, but White can defend with 5.gxf4 Bxf4+ 6.Kb2 Be5+ 7.Bc3 Rb4+ 8.Kc1 Bf4+ 9.Bd2 Ke6 10.Bxf4 Rxf4 11.Rc3;

b) 1...b5 2.Re1 Rxe1+ 3.Bxe1 Rc4 4.Rxc4 bxc4 5.Kc2 Kf7 6.g3 and a draw is the correct outcome.

The conclusion is that Black has a temporary initiative but no real advantage.

Despite his reputation as the scourge of world champions, Efim Geller had his hands full with Yuri Balashov, losing four games, drawing ten, and scoring just a single win against the Moscow grandmaster.

Magnus goes astray



Judging from his current position near the top of the chess world, the Norwegian GM Magnus Carlsen doesn't make too many unforced errors. But an instructive counterexample occurred in his game with the Russian GM Peter Svidler from an international tournament in the Athens suburb of Kallithea in 2008.

In the first diagram, Magnus is playing White and is on move. Objectively, the most reasonable plan is to attack Black's g-pawn with 19.dxe6 fxe6 20.h4, bringing White's kingside pieces into action with the minimum of delay. But Magnus tries a different idea.

19.g3?

The idea behind this move is clear enough. White intends to mobilize his pawn majority with gain of time by attacking Black's bishop with f3-f4. But there is a flaw – a forcing variation that interrupts the smooth flow of White's game:

19...exd5 20.exd5 Bc2! 21.Rc1 Bg6

Things have obvously gone wrong for White, and no easy remedy is available. There are only two moves to keep White in the game. One is 22.g4, which is met simply by 22...Bxh5, and the other is the text move:

22.f4

Now if Black's bishop retreats from e5, White can protect his knight with 23.Be2.

22...Bxh5! 23.fxe5 Nd7! (second diagram)

As a result of the adventure inaugurated by 19.g3, White's pawn centre is now lifeless and exposed. At the grandmaster level one could regard Black's remaining task as a matter of technique.

The conclusion is that Magnus did not seek out Black's strongest reply when he decided on the move 19.g3? This represents a psychological failing that is far more common below the master level.

Fritz vs Fred


Fred, of course, is Fred Reinfeld. Fritz is our well-known German friend. Fred Reinfeld died in 1964, while Fritz wasn't “born” until 1992.

There is something of Fred in all human players. We don't see everything there is to see on the chessboard. Fritz doesn't either, but he's a machine – a machine that is tactically perfect within a certain range. Today we're going to turn him loose on one of Fred's annotations.

The diagram position comes from the game Tarrasch-Blackburne, Hastings 1895, and was annotated by Fred in his book Tarrasch's Best Games of Chess, published by Chatto & Windus in 1947. Blackburne is being attacked, and his last move was the reckless 26...g5. Tarrasch was ready:

27.Rxh6!

“A really elegant solution,” writes Fred. Fritz agrees, although he also points out that White can win with the prosaic 27.Bxg5 hxg5 28.Qxg5+ Kf8 29.b4! Na6 30.Bg6 Rd7 31.a3 Nc7 32.h4!, when Black is in a huge bind and cannot stop the march of White's h-pawn. A personal view perhaps, but I suspect that Siegbert Tarrasch's arch-rival Aron Nimzowitsch would have played the position this way.

27...gxh4?!

This loses in simple fashion, but what else can Black do? Fred points out that that White is mating by force after 27...Rxh6 28.Bxg5 Qc7 29.Bf6+! Very nice.

More stubborn was 27...Kxh6, and here is where things get interesting. Fred attaches one of his many exclamation marks to the move 28.Bxg5+, says that White wins, and begins to ramble on about Blackburne's poor handling of the French Defence. Fritz agrees that White can win after 28.Bxg5+, but shows that he must play accurately after 28...Qxg5!. Here is how the win is achieved: 29.Rf6+ Kh5 30.Qh3+ Qh4 31.g4+ Kg5 32.Qe3+ Kxg4 33.Rf4+ Kh5 34.Rxh4+ Kxh4 35.Qg3+ Kh5 36.Qf3+! Kh4 37.Qf6+ Kg4 38.Qg7+ Kf3 39.Kg1! (the star move, helping to close the net around Black's king) 39...Rxh2 (no better is 39...Bc6 40.Qg3+ Ke2 41.Qf2#) 40.Qf6+ Kg4 41.Qxd8 Rxc2 42.Qd1+ Kf5 43.Qxc2+ Kxe5 44.Qh2+ Ke4 45.Qe2+ Kd4 46.Qf2+ Kc3 47.Qxc5 and Black must resign. I don't think Fred saw any of this.

Instead of 28.Bxg5+, White has the more practical 28.Rf6+!? Kg7 29.Qxg5+ Kf8 30.Rh6!, leaving him with two extra pawns and an easy win after 30...Qxg5 31.Rxh8+ Qg8 32.Rxg8+ Kxg8 33.Bxd8. I found this myself, long before I met Fritz.

28.Rxh8

Now Black is getting mated no matter what he does, and therefore Blackburne resigned (1-0)

Alekhine on New York 1927





Alexander Alekhine's book of the New York 1927 international tournament is an acknowledged classic in European countries but is almost unknown in North America. The reason is simple: the book was published in German, and a proper translation has never been made available in English. Today we are going to remedy that situation to a small degree by presenting Alekhine's annotations to one of the more interesting games of the tournament: the first-round encounter between Frank Marshall and Aron Nimzowitsch.

Before this game, Marshall's lifetime score against Nimzowitsch stood at 2 wins, 3 losses, and 4 draws. He had won their last encounter (at Marienbad 1925) and was probably eager to level the scores, especially since he had the White pieces here. His choice of the Exchange Variation of the French Defence was a strange one for this purpose, although he gave it a typically aggressive interpretation. Nimzowitsch handled Marshall's attacking ideas in his own deeply positional style, and the result was an impressive victory, at least on the surface...

The commentary in standard font is by Alekhine from his book Das New Yorker Schachturnier 1927, while the commentary in italics is by Nimzowitsch from his book Chess Praxis. There are some interesting points of disagreement!

Marshall -- Nimzowitsch
New York 1927 (1)
French Defence C01


1.e4 e6 2.d4 d5 3.Nc3 Bb4 4.exd5 exd5 5.Nf3

With this move White voluntarily gives up any pretensions to an opening advantage; moreover, by exchanging on c3 at a convenient moment, Black obtains chances of creating an enduring weakness in White's position in the form of doubled pawns. The immediate 5.Bd3 is therefore played more often.

5...Ne7 6.Bd3 Nbc6 7.h3

If 7.0-0 immediately, then 7...Bg4 would not be very pleasant for White. The asymmetrical development of the king's knights has not turned out in White's favour.

7...Be6

Nimzowitsch is emboldened by his opponent's unsuccessful handling of the opening and he therefore avoids the natural exchanging manoeuvre 7...Bf5 in favour of a plan that is complicated and interesting, but also not completely correct.

8.O-O Qd7 9.Bf4

Simpler was 9.Ne2 with approximately equal play. However, the move in the game is also not to be criticised – it actually gives good practical results because it provokes the opponent into some risky experimentation.

9...Bxc3

Over the past few years, play against weak doubled pawns has become one of Nimzowitsch's favourite strategic motifs; and he plays such positions, which he knows how to obtain in the most varied openings, with particular virtuosity. However, in the present case he is not on the right track because the insecure position of his own king is bound to interfere with the exploitation of his opponent's weak points. Of course, with the move 9...Bd6 he could have easily equalised the game.

10.bxc3 f6

In order to safeguard the bishop against a possible Nf3-g5 – the prophylactic meaning of 7...Be6 is thus clear. White now tried an attack on the open b-file, but it is not surprising that it failed, on account of the dynamic weakness of the double complex.

A necessary consequence of his previous move. Because the king bishop has disappeared from the board, the dark squares must be defended as far as possible by pawns – but now the square e6 has been weakened.

11.Rb1 g5 12.Bg3 O-O-O (first diagram)

Looks risky, but is part of the plan initiated on the 9th move.

The king takes on the defence of the pawns on b7 and c7.

Generally speaking, the role of the king in defence has been seriously underestimated for a long time, particularly after the sad fiasco suffered by the efforts of the older Steinitz to use the king – with many other pieces still on the board – as an inducement for his opponents to attack. It is only the period since the Great War that has brought changes in this regard; see, for example, the games of the match in Buenos Aires, where even in the middlegame the kings often served to protect certain squares where a breakthrough was threatened; in other words, they played an active role well before the endgame.

Of course, Black's last few moves – by their directness and, in a certain sense, their strategic novelty – make a very favourable impression on anyone who believes in the evolution of chess strategy and its extension to new depths. Therefore it is almost vexatious to discover – after a very close examination of the position – that this plan is not only not the best, but that the correct response by the opponent – and not a difficult one to find at that – would actually put Black in a highly unenviable situation.

In view of all this it was better to forgo 11...g5 and play instead the more modest 11...Nd8 followed by 0-0, etc.

13.Qe2?

Marshall's equilibrium has been disturbed by his opponent's boldness, and he commits – both here, and later on – a series of inaccuracies that are difficult to remedy. For example, instead of the queen move – which carries only the crude and easily-parried threat of 14.Ba6 – a less-stereotyped plan of attack was appropriate: 13.Nd2! If, say, 13...Nb8; then 14.Nb3 b6 15.Qe2 – this time with really unpleasant threats. It would therefore be better for Black to reply to 13.Nd2 with 13...Na5 with the aim of exchanging off the enemy knight on its way to c5. However, notwithstanding that this exchange would restore White's pawn position on the queenside and would therefore demonstrate the insufficiency of the plan begun by the move 9...Bxc3, White would in any case be under no obligation to play the immediate 14.Nb3; very strong instead would be Qd1-c1 (followed by Qc1-a3 when appropriate) and only then the move of the knight. It is not difficult to convince oneself that by adopting such a plan of play White would obtain an enduring initiative. Now, on the other hand, he gradually runs into difficulties.

13...Rde8!

Not 13...Rdg8 because a flank attack is best undermined by a concentration in the centre and not by a counter-attack on a wing.

Defence (by clearing the square d8 for the king) and counterattack at the same time.

14.Rfe1

If 14.Ba6 then 14...bxa6 15.Qxa6+ Kd8 16.Rb7 Nf5! 17.Rxc7 Qxc7 18.Bxc7+ Kxc7 with an easy win.

14...Nf5 15.Bxf5(?)

The move 15.Ba6 proves insufficient after 15...bxa6.

It is only through the absence of this bishop that White's queenside pawns become really weak – and this promises White a difficult endgame. In spite of the obvious danger, more chances were offered by 15.Bh2.

15...Bxf5 16.Qb5 Nd8 17.Qc5?

The decisive mistake, giving Black an opportunity to set up – with tempo – a solid defensive position on the queenside. By playing 17.Qa5! Marshall could have prevented this, since if 17...Kb8 then 18.c4! and the resulting complications are not unfavourable for White.

17...b6 18.Qa3 Kb7 19.Qb3

The beginning of a tragedy: the square c2 can hardly be defended otherwise.

19...Nc6

Already a blockader makes for c4 where it will demonstrate the weakness of the doubled pawn.

20.Nd2

On the 13th move this would have been the start of a very promising attack, but now it is just a modest defence against the threat of a knight invasion on c4. The storm clouds are gathering.

20...Na5 21.Qb2 Rxe1+ 22.Rxe1 Re8

The double exchange of rooks is connected with a purely tactical idea (to say nothing of the fact that Black does not need these pieces in order to realise his advantage): Black eliminates the threat of Nb3-c5+ (after Nd2-b3) and at the same time he avoids the exchange of knights, which would otherwise be forced.

23.Rxe8 Qxe8 24.Qb1

What else could White do? If 24.Kf1, for example, then 24...Qa4 would be very strong.

24...Kc8(?)

Here 24...Qe2 was also good.

Time pressure, obviously; otherwise one cannot understand why Black did not play 24...Qe2! Then after 25.Qc1 White would be practically stalemated, while in case of 25.Nb3 Nc4 26.Nc5+ Kc8 27.Nd3 Nd2! Black would win material and also retain the attack.

25.Qd1 Qe6

Also strong was 25...Qc6.

26.Nb3 Nc4 27.Nd2 Na3 28.Nf1 Nxc2

Now Black has an ending with a pawn plus but bishops of opposite colours, and many of the onlookers prognosticated a draw.

Because of the presence of opposite-coloured bishops, White could perhaps reconcile himself to the loss of this pawn, if not for the structural weaknesses on his queenside. But now he can only wait while his opponent prepares the fatal blow.

29.Qh5 Bd3 30.Qd1 Qe4

Not 30...Qe2 at once because of 31.Qxe2 and 32.Ne3.

31.Nd2

If 31.f3 then 31...Qe2 is sound.

31...Qe2 32.Qxe2

After 32.Qc1 Ne1! White would gradually perish from suffocation.

32...Bxe2 33.f4 Na3 34.fxg5 fxg5 35.Kf2

Otherwise Black plays 35...Nb5 followed by Be2-d3, etc.

35...Bh5 36.Be5 g4 37.hxg4

Black can only welcome pawn exchanges because on the other wing he has enough material for a win. Therefore from the practical point of view it was better to play 37.h4.

37...Bxg4 38.Ke3 Bf5 39.Bg7 (second diagram) 39...Be6!

Threatening to win a pawn with 40...Nb5, which if played immediately would be premature on account of the possible reply c3-c4. White, being obviously in time pressure (the 40th move!) does not notice the threats, and after this the endgame does not present his opponent any difficulties whatsoever. However, Black would also win after 40.Kd3!, for example: 40...Kd7 41.Bf8 Bf5+ 42.Ke3 Nc2+ 43.Kf4 Bg6 44.Ke5 Ne3, etc.

40.Bf8? Nb5 41.Nb1 a5

Here 41...Bf5 was also playable: 42.a4 Bxb1 43.axb5 Ba2 44.Kf4 Bc4 45.Ke5 Kd7 46.Bb4 c6 47.bxc6+ Kxc6 and the king migrates to b3.

Also possible was 41...Bf5, since if 42.a4 Bxb1 43.axb5, after which the simplest way for Black is Kc8-d7 followed by c7-c6 (in case of Ke3-f4-e5). After the exchange of pawns his king gets to c4.

42.Kd2

A winning line, not unlike that shown in the preceding note would be: 42.Kf4 Bf7 43.a4 Bg6 44.axb5 Bxb1 45.Ke5 Ba7 46.Ke6 Bc4 with 47...Kb7 and 48...c6, etc.

42...Bf5 43.Na3 Nxa3 44.Bxa3 Bb1 45.Bf8 Bxa2

Marshall could have quietly spared himself the following 15 moves.

46.Bg7 Bc4 47.Ke3 Kb7 48.Bf6 Ka6 49.Kd2

If 49.Bd8, Black has a win, the king penetrating to b3, e.g., 49.Bd8 Kb5 50.Bxc7 Kc4 51.Bxb6 a4, with 52...Kb3, and wins as the a-pawn cannot be stopped. This variation shows the enduring weakness of the dead and gone double complex. For in the passed a-pawn is mirrored the weakness of the defunct White a-pawn, and in the blocked long diagonal f6-a1 is manifested, in memoriam, the obstructive effect of the pawn formation c3 and d4. White might have resigned here.

49...Bf1 50.g3 Kb5 51.Kc1 Kc4 52.Kb2 c5 53.Be5 cxd4 54.Bxd4 b5 55.Bb6 a4 56.Ba5 d4 57.cxd4 b4 58.Bb6 a3+ 59.Ka2 Kb5 60.Bc5 Ka4 White resigned. 0-1
