[Event "USSR Championship"] [Site "?"] [Round "0"] [White "Kasparov"] [Black "Gavrikov"] [Result "1-0"] [ECO "D30"] [Opening "QGD: Tarrasch without Nc3"] 1. d4 d5 2. c4 e6 3. Nf3 {This move order gives White more options against the Tarrasch than 3.Nc3, when Black, in addition to the "normal" lines has several sharp and unclear gambit variations to choose from.} 3... c5 {The Tarrasch Defense is well known to Gavrikov who has played it on a regular basis. Black's idea is to take an isolated d-pawn in exchange for active piece play.} 4. cxd5 exd5 5. g3 Nc6 6. Bg2 Nf6 7. O-O Be7 8. dxc5 Bxc5 9. Bg5 { I prefer the pinning of Black's knight to the newer systems involving 9.Nbd2.} 9... O-O 10. Nc3 d4 11. Bxf6 Qxf6 12. Nd5 {It was Jan Timman who first employed this move, securing the central light squares. The older 12.Ne4 presents fewer problems for Black.} 12... Qd8 {This retreat is Black's safest. 12...Qd6 Blocks the a3-f8 diagonal, which may be needed by the dark squared bishop.} 13. Nd2 {Now the light squares are covered by an impressive army of two knights and a bishop, and the b3 and c4 squares are open for occupation by the Nd2.} 13... a6 {It is tempting to regard this move as an outright blunder, even though until this game was played it was considered playable.} 14. Rc1 Ba7 15. Nc4 {Previously this piece had been wandering to the less effective e4 square, where it only got in the way. This new idea was well prepared.} 15... Rb8 {Such timidity is not a permitted luxury in this opening. 15...Bh3 16.Bxh3 Qxd5 17.Bg2 Qe6 is only slightly better for White due to Black's isolated d- pawn.} 16. Nf4 b5 17. Nd6 Qxd6 18. Rxc6 Qd8 {18...Qe5 19.Nd3 Qf5 20.Rd6 is much better for White since Black's pieces are tied down to each others defense.} 19. Qc2 a5 {With the idea of developing the bishop to a6.} 20. Rc1 { White's advantage is mounting and the tripling on the open c-file is the cause of Black's future problems.} 20... Re8 21. Bd5 { The beginning of a fantastic attack based on Black's light squared weaknesses.} 21... Bb6 22. Qb3 {Not a single light squared wasted!} 22... Re7 23. Bf3 { Keep your eye on this piece.} 23... Re5 24. Bh5 g6 {Now White is able to take advantage of Black's f-pawn which is pinned on the a2-g8 diagonal.} 25. Bxg6 { The point. It is not the move itself which deserves our admiration but the incredible build up, the epic journey of that bishop, which just 5 moves ago stood on g2!} 25... hxg6 26. Rxg6+ Kf8 27. Rh6 Ke7 { 27...Kg7 would allow White a brilliant mating attack.} 28. Rcc6 Rf5 {Played wit h the idea of covering the f7 square. 28...Bd7 would allow White a mating continuation.} 29. Qf3 Bc7 {The Black rook is overworked on the 5th rank.} 30. Qe4+ Re5 31. Ng6+ fxg6 32. Rh7+ Kf8 33. Qxg6 { Black resigns as despite his two extra bishops, he cannot avoid mate.} 1-0
