[Event "World Championship"] [Site "?"] [Round "19"] [White "Kasparov"] [Black "Karpov"] [ECO "E21"] [Opening "Nimzo-Indian: Three Knights"] 1. d4 Nf6 2. c4 e6 3. Nc3 Bb4 4. Nf3 Ne4 {An unusual move, especially from Karpov, a Classical player. Still, he clearly wanted to disrupt the opening, to neutralize anything I might have prepared.} 5. Qc2 f5 6. g3 Nc6 {This was co mpletely new. 6...b6 7.Bg2 Bb7 This would have transposed into a Classical Dutch defense.} 7. Bg2 O-O 8. O-O Bxc3 9. bxc3 Na5 {Karpov is combining some of the ideas he had used in previous games from this match. But I have two trump cards, a lead in development and the bishop pair .} 10. c5 d6 11. c4 { This is a strong pawn sacrifice. If Karpov accepts, then 12,Ba3 is a goodreply. } 11... b6 {But declining the sacrifice was incorrect. Probably Karpov thought that I was going to play 12.Nd2, but I have better uses for that square.} 12. Bd2 Nxd2 {12...dxc5 13.Bxa5 bxa5 14.Rfd1 White has much better prospects.} 13. Nxd2 d5 {All the commentators seemed to disapprove of this move, but in fact the error was in the entire opening strategy. At this point he was already in deep trouble.} 14. cxd5 exd5 15. e3 Be6 {Black is doomed to passive play while White can easily improve the position of the major pieces.} 16. Qc3 Rf7 17. Rfc1 Rb8 18. Rab1 Re7 19. a4 Bf7 20. Bf1 h6 21. Bd3 Qd7 22. Qc2 Be6 { 22...g6 would have been a little stronger.} 23. Bb5 Qd8 24. Rd1 g5 {Finally Kar pov gets tired of waiting and launches a counterattack. But there is no piece support for the pawnstorm.} 25. Nf3 {I will plant this knight at e5. In addition, I will be able to place my bishop at e4, though that takes quite a bit of preparation.} 25... Rg7 26. Ne5 f4 27. Bf1 { The bishop did its job on the queenside. Now I need it in the center.} 27... Qf6 28. Bg2 Rd8 29. e4 {It is time to open up the game. I am effectively a piece ahead, since the enemy knight is stranded at a5.} 29... dxe4 30. Bxe4 Re7 31. Qc3 Bd5 32. Re1 Kg7 33. Ng4 {Now the weakness at g5 is felt.} 33... Qf7 34. Bxd5 Rxd5 35. Rxe7 Qxe7 36. Re1 Qd8 37. Ne5 Qf6 38. cxb6 {Opening more lines.} 38... Qxb6 {38...cxb6 39.Qc7+ Kg8 40.Ng4 Qg7 41.Re8+ Kh7 42.Re7} 39. gxf4 { Open lines on the queenside. Open lines in the center. Open lines on the kingside!} 39... Rxd4 {A blunder in time pressure, but the game would not have lasted long anyway. 39...gxf4 40.Qf3 Qe6 41.Kh1 Rxd4 42.Qg2+ Kh7 43.Rg1} 40. Nf3 Nb3 41. Rb1 Qf6 { The game was adjourned here, but I played my move in public anyway.} 42. Qxc7+ *
