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.

The Forklift


From humble beginnings in the early 1950s, chess-playing computers have now surpassed the strongest human players. Less than $100 is needed to buy one of the electronic warriors that gave so much trouble to GMs Garry Kasparov, Vladimir Kramnik, and Michael Adams in specially-arranged test matches.

Twenty years ago, when chess computers were first approaching master strength, an initiative was started to prohibit them from entering human tournaments. It was argued that trying to defeat a machine at chess would eventually be as futile as trying to win a powerlifting contest against a forklift.

In 2009, a FIDE Category 6 tournament with a mostly human entry was won by a mobile phone.

These days many authorities proclaim the futility of trying to defeat a top chess-playing program. Instead it is recommended that players use such programs to analyse their own games and identify and perhaps correct their mistakes.

I recently acquired a copy of Fritz 12, the newest version of one of the best-selling chess programs of all time. Never mind the advice from the experts. When the DVD arrived at my study, I installed the program, set the time control for 5 minutes each, and banged out my first move 1.e4. Here is the resulting game:

Dadian-Fritz 12, G/5, Port Coquitlam 2010

1.e4 c6 2.d4 d5 3.exd5 cxd5 4.Bd3 Nc6 5.c3 Nf6 6.Bf4 g6 7.Nf3 Bg7 8.0-0 0-0 9.h3 a6 10.a4 Nh5 11.Bh2 Bh6 12.Re1 Bf4 13.Bxf4 Nxf4 14.Bc2 f6 15.Qd2 (diagram) 15...e5 16.dxe5 fxe5 17.Nxe5 Qg5 18.Ng4 h5 19.Ne3 Ne5 20.Kf1 Bxh3 21.gxh3 Nf3 0-1

Well, that was a sobering experience. I thought the exchange variation of the Caro-Kann was supposed to be a safe way for White to play, but I guess not.

Of course my first big mistake was 16.dxe5, which opened the f-file and also allowed Black's queen to get to g5. Replace 16.dxe5 with 16.Qe3 and White should be fine.

On the very next move I made my second big mistake 17.Nxe5, which allowed Black to set up a winning attack with 17...Qg5. Instead of taking the e-pawn there was the interesting option of counterplay with 17.Bb3.

After 17...Qg5 I managed to grovel for a few moves but the issue was settled after 20...Bxh3!

I suppose there is some risk of embarrassment in publishing this game, but here I will appeal to the reader's conscience.

Seven Brutalities 7


My opponent in this game is a rated expert with an aggressive style of play who has victimised a number of masters, myself included. I decided to play the Scandinavian Defence because unless White knows some exact theory he can easily overreach himself. However it soon becomes evident that White is playing for a draw.

P.Burke - D. Scoones
Labour Day Open, Langley 2007
Scandinavian Defence B01

1.e4 d5 2.exd5 Nf6 3.Nc3 Nxd5 4.Nxd5?!

This ill-considered exchange gives Black's queen a central position from which she cannot be easily dislodged. More common is 4.Bc4 Nb6 5.Bb3 when Black must tread very carefully.

4...Qxd5 5.Nf3

If 5.Qf3 the best remedy is 5...Qe6+ 6.Qe2 Nc6 7.Qxe6 Bxe6 8.Bb5 Bd5! 9.Nf3 0–0–0 which favours Black after 10.Bxc6 Bxc6 11.d3 e5 12.Be3 Bd6.

5...Nc6 6.d4 Bg4 7.Be2 0–0–0 8.Be3

White's best try is 8.0–0 Nxd4 9.Nxd4 Bxe2 10.Qxe2 Qxd4 11.Rb1!? with some compensation for the pawn.

8...e5 9.0–0 exd4 10.Nxd4 Bxe2 11.Nxe2 (diagram)

Time for an assessment. Black has an edge in development and before it fades away he must try to turn it into something more concrete.

11...Qc4!?

The alternative 11...Qb5 12.Nc3 Qxb2 13.Nd5 Qe5 wins a pawn but this would give my opponent an open file against my king and some cheapo potential.

12.Bd2

If 12.b3 Rxd1 ( 12...Qh4!?) 13.bxc4 Rxa1 14.Rxa1 Ne5 with continuing problems for White.

12...Bd6 13.b3 Qh4 14.g3 Qh3 15.Kh1 Qf5

Also possible was 15...h5 16.Ng1 Qf5.

16.f3 Rhe8 17.a3 Bc5

Here Black can play 17...Bxa3!? with the idea of 18.Rxa3 Qd5 but as before I did not want to give my opponent any open lines against my king unless his queen is exchanged or at least driven to a passive position.

18.Nf4 Ne5

A preventive move directed against 19.Nd3, blocking the d-file.

19.Qc1 g5 20.Ng2 f6

Also possible was 20...Nxf3 21.Bxg5 Re2 22.Qf4 Qxg5 23.Rxf3 Qxf4 24.Nxf4 Rxc2.

21.Be3 Bxe3 22.Qxe3 Nc6 23.Qf2 Nd4 24.Ne3 Qc5

Time for another assessment. In order to meet Black's concrete threats White has had to make a number of pawn moves but that has not relieved the pressure. Black has a definite advantage but notching the full point will not be simple... unless White makes further mistakes...

25.b4?

Stronger was 25.Rad1 Qxa3 26.Rd3 Qc5 27.c4 with some counterplay for White. The text also gives up a pawn but has the added drawback of allowing an effective simplifying combination.

25...Qc3 26.Rfe1 Rxe3!

Black has a winning rook ending after 27.Qxe3 Qxe3 28.Rxe3 Nxc2 29.Rae1 h5 30.R1e2 Nxe3 31.Rxe3 Rd1+ 32.Kg2 Rd2+ 33.Kg1 Kd7. My opponent decided he had seen enough and stopped the clocks.

0–1

Seven Brutalities 6


I was looking for some revenge here because my opponent had won our only previous encounter. When an opportunity arose for an interesting knight sacrifice, it didn't take me long to make the big decision. Because Black could have resigned on move 25 I have decided to call this game a miniature, even though it went slightly over the limit!

Scoones,D - Neufahrt,G

Labour Day Open, Victoria 1989

English Opening A10

1.c4 g6 2.Nc3 Bg7 3.g3 c6 4.Bg2 d6 5.d4 Nd7 6.e3 f5?!

This is not the best reaction to White's restrained system of development. It is unlikely that Black will successfully challenge White on the central light squares and there are even fewer prospects of getting in an effective break with ...f5-f4. Preferable was 6...Ngf6.

7.Nge2 e5 8.b3 Ne7 9.a4?!

An unnecessary precaution. Today I would play an immediate 9.Ba3 and now: a) 9...exd4 10.exd4 Nf6 11.0-0 0-0 12.Re1; or b) 9...Nf6 10.dxe5 dxe5 11.Qxd8+ Kxd8 12.Rd1+ Ke8 13.Bd6; with advantage to White in both cases.

9...e4

Rather ambitious since White is well-placed to attack Black's pawn centre. It was better to castle first and decide on a plan later.

10.f3 d5

Black meets the attack on his advanced e-pawn by building up his pawn centre. There were two other approaches: a) ignoring the attack and seeking active play with 10...0–0 11.fxe4 fxe4 12.Nxe4 d5, but after 13.Nf2 there might not be enough compensation for the pawn; b) exchanging on f3 and giving White a backward e-pawn with 10...exf3 11.Bxf3 Nf6, but this allows White to retain an edge after 12.0–0 0–0 13.Qd3 Qc7 14.Ba3 Bd7 15.b4. The move in the game is best, if only because it is the most consistent.

11.cxd5 cxd5 12.Ba3 Nf6 13.Nf4!?

With this move White threatens to win the d-pawn with 14.Bxe7 – unless Black is willing to displace his king. Neufahrt decides to call White's bluff. But who is bluffing whom?

13...g5!? (diagram)

14.fxe4!

After 14.Bxe7 Kxe7! 15.Nfe2 Kf7 Black's king position is a minor inconvenience that is more than compensated by his strong pawn centre. But White's true intention was the move in the game, offering the sacrifice of a piece for interesting play.

14...gxf4

Black is not forced to accept the offer. Playable is 14...fxe4 15.Nh5 0-0 16.0-0 Be6, although White can perhaps maintain some initiative with 17.Nb5. In view of what happens in the game, this was what Black should have played. But Neufahrt is never one to back down from a challenge!

In making this sacrifice I did not calculate all of the variations to the end. It was enough to see that in the major lines White must have sufficient compensation for the piece. Add to this the multitude of threats and the practical difficulties imposed by the clock and it was clear that Black's defensive task would be a difficult one.

15.e5 Ne4?!

This would be the best move if Black had already castled. In that case the exchange on e4 would not be a good idea for White because of the weakened light squares around his king. It was better to play 15...Ng4, when there are two main variations: a) 16.exf4 Ne3 (stronger than 16...Be6 17.Qd3 0–0 18.h3 Nh6 19.Bxe7 Qxe7 20.Bxd5 etc.) 17.Qh5+ Ng6 18.Kf2 Nxg2 19.Kxg2 a6 20.Rac1; b) 16.Bxe7 Qxe7 17.Nxd5 Qf7 18.exf4 Be6 19.Qd3 0–0 20.Nc3 Bxb3 21.h3 Nh6 22.Rb1 Bc4 23.Qe3 Rab8 24.Kf2. In both cases White has good compensation for the sacrificed piece.

16.Bxe4 fxe4 17.Qh5+ Ng6

Exchanging queens with 17...Kf8 18.gxf4 Qe8 19.Qxe8+ Kxe8 does not bring Black any happiness after 20.Bxe7 Kxe7 21.Nxd5+ Kd8 22.Rc1 Bf5 23.Rg1 Bf8 24.Rg5.

18.exf4 Qd7

If 18...Qa5 19.Rc1 Bd7 20.0–0 Bc6 then 21.Bc5 Bf8 22.b4 Qd8 23.Bxf8 Rxf8 24.f5 with a winning position for White.

19.Nb5 Bf8?!

Black is ahead in material and under some pressure so it's very natural to want to exchange pieces. But a defender's tactical operations must be accurate and this one is nothing of the kind. A better try was 19...Qg4 20.Nd6+ Kd8 21.Qxg4 Bxg4 and now White can keep the advantage with 22.h3! (stronger than 22.Nxb7+) 22...Bf3 23.Rh2!

20.e6!

Black must have overlooked this retort. The pawn cannot be captured because of Nb5-c7+, winning the queen.

20...Qd8 21.Bxf8 Kxf8

No better was 21...Rxf8 22.f5 and along with his other advantages White recovers the sacrificed piece.

22.f5 a6 23.fxg6 axb5 24.0–0+ Kg8

Or 24...Ke7 25.Rf7+ Kd6 26.Rc1, slamming all the doors on the Black king.

25.g7! Kxg7 26.Rf7+ 1–0

This loss must have dented my opponent's morale because I won all the rest of our encounters. As Larsen once wrote, some games bring more than one point!

Seven Brutalities 5


The safety of one's king is an important factor in chess, but when assessing a position one must take a concrete approach and consider other factors as well. Sometimes there is an opportunity to win material or gain another advantage at the cost of some inconvenience to one's king. If this inconvenience amounts to only a few checks then the king was obviously not unsafe at all. Here is a game illustrating this concept.

Scoones D – Zimmer E
Victoria Winter Open 1983
Queen's Gambit Accepted D24
1.d4 d5 2.Nf3 Nf6 3.c4 dxc4 4.Nc3 a6 5.e4 e6 6.Bxc4 b5 7.Bd3 c5 8.e5 Nd5 9.Ne4 c4 10.Bb1 Nd7 11.Nfg5 Bb4+ 12.Bd2 Bxd2+ (diagram) 13.Kxd2 Qa5+ 14.Kc1 c3 15.bxc3 Nxc3 16.Qf3 Qa3+ 17.Kc2 Qa4+ 18.Kxc3 Qc4+ 19.Kb2 Qxd4+ 20.Qc3 Qd5 21.Nd6+ Ke7 22.Be4 1-0

The sharp variation beginning with 4.Nc3 was analysed by IM John Watson in a long article in the early 1980s, the main line going 4...a6 5.e4 b5 6.e5 Nd5 7.a4 c6 8.axb5 Nxc3 9.bxc3 cxb5 10.Ng5. At this point another 1983 game Scoones-Hunt saw Black go wrong with 10...e6? The idea was a good one: to meet 11.Qf3 with 11...Ra7, saving the rook and simultaneously defending f7. The problem was the shot 11.Nxf7! when Black was already busted. Instead of Hunt's 10...e6? Black must play 10...f6!? 11.Qf3 Ra7 with an extra pawn in exchange for White's lead in development.

In the main game, Black avoided complications with 5...e6, which allowed White to regain his pawn immediately.

White should meet 8...Nd5 with 9.Bg5! aiming for a favourable exchange of dark-squared bishops since after 9.Ne4?! Black could have tried 9...cxd4 10.a4 Nb4 with complications. Instead, 9...c4 took all of the pressure off White's centre.

After 11...Bb4+ 12.Bd2 Bxd2+ White could not resist the cheeky 13.Kxd2!? even though retaking with the queen was objectively stronger. The point was the obvious continuation 13...Qa5+ 14.Kc1 when the complications appear to favour White. Instead of 13...Qa5+?! Black could have played 13...Kf8!, defusing the knight check on d6.

Black went seriously wrong with 14...Nxc3?, allowing White to gain a decisive advantage with the double attack 15.Qf3. He could have stayed in the game with 14...Qa3+ 15.Kd2 b4.

After 20.Qc3 Black's checks quickly ran out and when 22.Be4 was played he decided he had seen enough.

Seven Brutalities 4


Sitting down to the board to begin play, you never know when you are going to be involved in a so-called miniature game (of 25 moves or less). If your opponent is relatively weak there could be some advance clue, but when you're up against a strong player there's no way of foreseeing the result, much less the number of moves you will play. It's just a roll of the dice.

Reeve J - Scoones D
Labour Day Open 1975
Spanish Game C68
1.e4 e5 2.Nf3 Nc6 3.Bb5 a6 4.Bxc6 dxc6 5.0-0 Bd6 6.d4 exd4 7.Qxd4 f6 8.Nbd2 Be6 9.Nb3 b6 10.Be3 Ne7 11.Qd2 c5 12.Rad1 Ng6 13.Qe2 Qe7 14.c4 0-0 15.Nfd2 (diagram) 15...f5 16.exf5 Bxf5 17.Rfe1 Rae8 18.Nb1 Qh4 19.g3 Qh3 20.Qf1 Qh5 21.Nc3 Ne5 0-1

Jeff Reeve is a strong master who has won many impressive games on the White side of the Ruy Lopez Exchange Variation. Before our last-round matchup in the 1975 Labour Day Open in Vancouver I was fiddling with a pocket set, trying to find something that would keep me in the game for awhile. Of course it was always going to be a sideline, and on this occasion my eye fell on the rare move 5...Bd6. I was sure my opponent would continue with 6.d4, which I intended to meet with 6...exd4 (7...f6 returns to one of the main lines) 7.Qxd4 f6.

On d6 the bishop is often vulnerable to exchange with Nd2-c4. But in looking at the position after 8.Nbd2 it occurred to me that Black could play the useful developing move 8...Be6. If White carries on with 9.Nc4 then Black wins a pawn with a minor tactic: 9...Bxh2+! followed by 10...Qxd4 and 11...Bxc4.

White sidestepped this variation with 8.Nb3 but his knight was left in an offside position. After 13...0-0 Black had completed his development and was very comfortable.

After this White began to drift, which can be seen from the sequence 14.c4?! 0-0 15.Nfd2?!, which merely decentralises a key defender. Black struck immediately with 15...f5!, guaranteeing himself a clear advantage after 16.exf5 Bxf5.

In the sequel the key strategic factor is Black's unopposed light-squared bishop. After 18.Nb1? Qh4 19.g3, fatal weaknesses had appeared in White's kingside. The centralising move 21...Ne5 leads forcefully to the win of at least the exchange. White decided he had seen enough and called it a day.

Seven Brutalities 3



At the time of this encounter, my opponent was a young B-class player. Today he is a rated master.

Scoones D - Vitko G
Portland 1976
Sicilian Defence B22
1.e4 c5 2.c3 Nf6 3.e5 Nd5 4.d4 cxd4 5.Qxd4 e6 6.Nf3 Nc6 7.Qe4 d6 8.Nbd2 Qc7 9.Nc4 dxe5 10.Ncxe5 Nxe5 11.Nxe5 (first diagram) 11...Nxc3 12.bxc3 Qxc3+ 13.Kd1 Qxa1 14.Bb5+ Ke7 15.Qb4+ Kf6 16.Ng4+ Kg6 17.Qe4+ Kh5 (second diagram) 18.Nf6+ Qxf6 19.Be2+ 1-0


Theory and practice have established that 7...f5!? is the strongest reply to White's move 7.Qe4. I think anyone coming upon this position for the first time would have a hard time agreeing to take on a backward d-pawn. It looks far more natural to exchange White's advanced e-pawn than to set it up as a future target.

In the position of the first diagram Black should play the defensive move 11...a6, preventing a bishop check on b5. Instead he is drawn into a tactical operation that wins the exchange. Unfortunately, it also leaves Black dangerously behind in development. After 13...Qxa1 White is able to strike immediately.

Instead of 15...Kf6 Black can play 15...Kd8 but this does not get him out of trouble. White follows up with 16.Nxf7+ Kc7 17.Qc4+ Kb8 18.Kc2! intending a decisive bishop check on f4. Black can then resign with a clear conscience.

After 17.Qe4+ Black may have been planning to put up a defence with 17...f5. Unfortunately for him this fails to the non-standard mating move 18.Be8.

White's final task is to jettison his knight in order to clear the way for his bishop. That is accomplished with the desperado move 18.Nf6+. After 18...Qxf6 the attractive switchback 19.Be2+ ends the game immediately.

Seven Brutalities 2


No one can win a game of chess unless the opponent goes wrong, so it might be said that inducing error is one of the primary tasks facing the tournament player. This assumes of course that one's technique is up to exploiting the error. There are many ways to send the opponent down the path to danger, and a popular one is playing an unexpected opening variation.

A few months before this game I had spent some time looking through a monograph on the Schliemann Defence by the Hungarian master Tibor Florian. I was reasonably prepared for the main lines, but got a pleasant surprise when my opponent wandered into a sideline that had first been seen in the nineteenth century.

Forbes G - Scoones D
B.C. Championship (1) 1977
Spanish Game C63
1.e4 e5 2.Nf3 Nc6 3.Bb5 f5 4.d4?!
The correct move here is 4.Nc3.
4...fxe4 5.Nxe5 Nxe5 6.dxe5 c6 (diagram) 7.Bc4?!
White has already gone wrong but this accelerates the negative trend. For better or worse the piece sacrifice 7.Nc3!? must be tried. I remember having an improvement on Florian's analysis but I can't remember what it was.
7...Qa5+ 8.Nc3 Qxe5 9.Bxg8 Rxg8 10.Qe2 d5 11.f4 Qf6 12.Bd2 Qh4+ 13.g3 Qh3
White is a pawn down and is being overrun on the light squares. No further commentary is required.
14.Nd1 Bg4 15.Nf2?! Bxe2 16.Nxh3 Bf3 17.Rg1 Bc5 0-1

It is always great to start a tournament with a quick win, especially as Black!

Seven Brutalities 1


Here is the first of seven miniature games taken from various stages of my so-called career. Each game features some hard-hitting tactical play... hence the title, borrowed from an old article in Joel Benjamin's magazine Chess Chow. (My favourite chess magazine of all time, by the way. After it folded unexpectedly I was depressed for months.)

Scoones D - Holzknecht A
Victoria 2005
Pirc Defence B08
1.d4 Nf6 2.Nf3 d6 3.Nc3 g6 4.e4 Bg7 5.Be2 0-0 6.0-0 Nc6 7.d5 Ne5 8.Nxe5 dxe5 9.Be3 Bd7 10.f3 Nh5 11.Qd2 e6 12.Bc4 exd5 13.Nxd5 c6 (diagram) 14.Bg5! 1-0

Al Holzknecht is a local expert who plays resolutely for a draw whenever he is up against higher-rated players. Needless to say, this approach does not always produce the desired result. This game is no exception.

7...Ne5 is hardly the best way for Black. Such theory as exists on this position says Black should retract his last move with 8...Nb8, as in the old game Leonhardt-Chigorin, Carlsbad 1907(!) In fact I have played 8...Nb8 myself with success.

The decentralising 10...Nh5 might have worked out if Black had continued with 12...Nf4!? If White accepts the pawn sacrifice Black gets excellent compensation through dominating the central dark squares.

Instead, Black exchanges pawns with the aim of clearing up the situation in the centre. Unfortunately, 13...c6? is not the correct follow-up, as White demonstrates. But even after the stronger 13...Be6 14.Rfd1 the position is better for White.

After 14.Bg5! Black is losing at least a pawn on account of his awkwardly placed queen and the unavailability of the defensive move 14...f6. Still, resignation was a pleasant surprise!

Impetuosity






One of my very favourite chess servers is Playchess.com. In order to join Playchess you must own ChessBase or one of its related playing programs such as Fritz, Shredder or Junior. Because of this prerequisite there are always strong players logged in and not surprisingly they are from all over the world.

As far as I know, ratings are calculated using the Glicko system. This system does not correspond exactly with the Elo system but is thought by its developer to be more accurate in terms of ranking and expected results.

Anyone who has played much anonymous speed chess knows that when you encounter a wide range of players you will eventually get an opportunity to win a miniature game with a combination straight out of Chernev or Reinfeld. Yesterday I got such an opportunity.

I am White in the first diagrammed position, which arose after the moves 1.e4 c5 2.Nf3 Nc6 3.d4 cxd4 4.Nxd4 d6 5.c4 Nf6 6.Nc3 Nxd4 7.Qxd4 Bd7 8.Be2 Bc6 9.0-0 Qc7?! Black's last move was not the best one. The reply was 10.Nd5! putting the question to the queen, to which my opponent replied 10...Bxd5 11.cxd5 Qc5?

Chasing after exchanges is a classic psychological failing. Here the consequences are immediate after White's next move 12.Qa4+!, which is very difficult for Black to meet. Moving his king is obviously out of the question, so he is forced to interpose with 12...Nd7. White now follows up with 13.Be3 Qc7 14.Rac1 Qd8, leading to the second diagram.

Black has lost so much time with his queen that White is already winning by force. Two unusual bishop moves do the trick: 15.Bg4! g6 16.Bb6!

Because of the mate on d7 it is obvious that 16...axb6 is the only move to save Black's queen. But with the rook on a8 now under attack White is able to conclude matters with 17.Bxd7+ Qxd7 18.Qxa8+.

Black was forced to resign here. After 18...Qd8 White has a pleasant choice between the simple 19.Rc8 and the more accurate 19.Qa4+ b5 20.Qxb5+ Qd7 21.Rc8 mate.

Is this Legal?



There I was, drinking my tea this morning, getting ready to go to work. I was up a bit earlier than usual, so there was time to get onto one of the chess servers for a quick game. I didn't realise just how quick... but of course one can never know this. My opponent was a Russian chap. His rating wasn't high, but respectable. A five-minute game, and I am Black:

1.e4 d5 2.exd5 Nf6 3.c4 c6 4.dxc6
If you are going to take this pawn, you have to know what you are doing.
4...Nxc6 5.d3 e5 6.Bg5
To the cognoscenti, the first sign that White is drifting.
6...Bc5 7.Nc3
Intuition is a funny thing. Here I knew my invisible opponent wanted to gang up on my pinned knight, so I made a move that helped his knight find the "right" square for this project.
7...Be6!?
No points, by the way, for 7...Bxf2+? 8.Kxf2 Ng4+ and now 9.Qxg4! leaves White a piece ahead when all the captures are over.
8.Ne4?
Taking on f6 and then playing 9.Ne4 doesn't help White after 9...Bb4+ 10.Nc3 Rd8 with unpleasant pressure (or pleasant pressure, depending on your perspective.)
8...Nxe4!
Again, no points for other moves.
9.Bxd8 Bxf2+ 10.Ke2 Nd4 mate.

Yes, I know: it's just Legal's mate with reversed colours. Nothing too special... except that I could not find a single previous example of this in any of the big databases!
