[Event "Moscow"] [Site "?"] [Round "0"] [White "Kasparov"] [Black "Sax"] [Result "1-0"] [ECO "D85"] [Opening "Gruenfeld: Exchange, 5.e4"] 1. d4 Nf6 2. c4 g6 3. Nc3 d5 { I have enjoyed playing this from both sides of the board.} 4. cxd5 Nxd5 5. e4 Nxc3 6. bxc3 Bg7 7. Bc4 {Also very popular is 7.Nf3.} 7... O-O 8. Be3 b6 { Attacking the center immediately with 8...c5 is more thematic.} 9. h4 Bb7 { 9...Nc6 10.h5 Na5 11.hxg6 allows White a winning kingside attack.} 10. Qf3 { This move reinforces White's center and is a plus for leaving the knight at g1. } 10... Qd7 11. Ne2 h5 12. Bg5 Nc6 13. Nf4 {White intends to play 14.Nxg6 taking advantage of the pin on the a2-g8 diagonal.} 13... e6 { 13...Na5 would allow White to win material.} 14. Rd1 Na5 15. Bd3 { White's strong center guarantees a lasting initiative.} 15... e5 {15...c5 16. Nxh5 gxh5 17.Bf6 Bxf6 18.Qxf6 Qd8 19.Qh6 With the idea of lifting the rook to g3 via h3 with a winning attack for White} 16. dxe5 Bxe5 17. O-O {White is much better in this position since Black's kingside has been seriously weakened with pawn h5, while Black's pieces are misplaced in particular the knight on a5.} 17... Qg4 {17...Qa4 18.g4 with a formidable kingside attack.} 18. Qe3 Rfe8 19. Be2 Bxf4 {19...Qc8 20.Nd5 Bxd5 21.Rxd5 when White stands much better because of his two bishops and kingside initiative.} 20. Bxf4 Nc4 {Embarking on an interesting combination which unfortunately fails to a counter not easily foreseen. Black refrained from 20...Qxh4 21.e5 because of his weakened dark squares.} 21. Bxc4 Rxe4 22. f3 Qxf4 23. Bxf7+ Kg7 { 23...Kxf7 allows White to win material by the use of a pin.} 24. Qd3 { White has achieved an ending in which Black will be hard pressed to maintain material parity.} 24... Qe3+ 25. Qxe3 Rxe3 26. Rd7 {This gains the seventh rank while threatening a discovered check with the bishop.} 26... Kh6 { 26...Rxc3 would drop a piece.} 27. Rxc7 Ba6 28. Rd1 Bd3 29. Rd2 Bf5 30. Kf2 Re5 31. Rd5 {As a general rule when one is ahead in material you should try to exchange pieces and not pawns, since the pawns will be able to promote later in the game.} 31... Rxd5 32. Bxd5 Rd8 33. c4 b5 34. Ke3 a5 35. Kf4 Bb1 36. g4 { The Black king finds itself in a mating net, the threat being 37.g5+ mate.} 36... hxg4 37. fxg4 Rf8+ 38. Kg3 { Black resigned since to avoid mate he must part with further material.} 1-0
