I was very impressed by the energetic play of GM Alexander Moiseenko in his game with GM Adam Horvath from the 2005 Saint-Vincent Open. Moiseenko got things going with a strong opening novelty, moved into gambit mode by sacrificing material for a lasting initiative, and then finished off his opponent with some nice tactical play.
1.d4 d5 2.c4 Nc6 3.Nc3 dxc4 4.d5 Ne5 5.f4 Ng4
This is a very sharp line of Chigorin's Defence. Black must be well-prepared in order to survive.
6.e4 e5 7.Nf3 Bc5 (first diagram)

8.Bxc4!
Here is Moiseenko's novelty, in place of the more usual 8.Qa4+. It looks like a mistake at first glance but things turn out otherwise.
8...Qe7
If 8...Nf2 9.Qb3 Nf6 10.Rf1 N6xe4 11.Ng5! and now 11...Nxc3 12.bxc3 0-0 13.Rxf2 h6 14.Nf3 Bxf2+ 15.Kxf2 e4 16.Ne5 Qh4+ 17.Kg1 Qe1+ 18.Bf1 leaves White on top.
9.Nxe5 Nxe5
After 9...N8f6 10.Bb5+ Kf8 11.Qf3 Nxe5 12.fxe5 Qxe5 would transpose to the game but instead of 11...Nxe5 Black might consider 11...Bd4!? with interesting play.
10.fxe5 Qxe5 11.Bb5+ Kf8 12.Qf3 Nf6 13.Bf4 Qd4 14.h3 Bd7
If 14...Bb4 15.Bd3 Bxc3+ 16.bxc3 Qxc3+ 17.Kf2 and White has excellent compensation for the sacrificed material.
15.Bd3 Bb4 16.a3
Perhaps 16.Be3 Qe5 17.0-0 Bd6 18.Ne2 was stronger.
16...Bxc3+ 17.bxc3 Qxc3+ 18.Kf2 (second diagram)

9.Nxe5 Nxe5

16...Bxc3+ 17.bxc3 Qxc3+ 18.Kf2 (second diagram)
18...Re8
I like 18...Qd4+ 19.Qe3 (if 19.Kg3 Nh5+ 20.Qxh5 Qxd3+ 21.Kh2 Qxe4 22.Bxc7 Qf5! and it is hard to imagine White eking out any winning chances) 19...Qxe3+ 20.Kxe3 Re8 21.Kf3 c6 22.d6 c5 23.Rac1 b6 24.Rhe1 h5! when it is still anyone's game.
19.Rhe1 c6 20.Kf1 h6 21.Bd6+ Kg8 22.Rab1 Bc8 23.Rbc1 Qd4 24.Bc5 Qe5 25.Bxa7 Bd7 26.Bf2 cxd5 27.exd5 Qxd5 (third diagram)
Over the preceding moves Black has not managed to neutralise White's pressure and the awkward position of his king is now a decisive factor. It's White to play and win by force!
28.Rxe8+ Bxe8 29.Qxd5 Nxd5 30.Rc8 Nf6 31.Bd4 Kf8 32.Bc5+ Kg8 33.Be7
The culmination of White's forced manoeuvre. Black must lose a piece and so he resigned here.
1-0
