Karpov vs Kasparov
[Event "World Championship"] [Site "?"] [Round "11"] [White "Karpov"] [Black "Kasparov"] [Result "0-1"] [ECO "D85"] [Opening "Gruenfeld: Exchange, 5.e4"] 1. d4 Nf6 2. c4 g6 3. Nc3 d5 {The Grunfeld Defense is a hypermodern opening. The strategic idea for Black, is to cede the center, then launch a counterattack against it, throwing White on the defensive.} 4. cxd5 Nxd5 5. e4 Nxc3 6. bxc3 Bg7 7. Bc4 c5 {Challenging White's center. 8.dxc5 would be a horrible blunder due to Black's response of 8. ... Bxc3+.} 8. Ne2 Nc6 9. Be3 O-O {White has set up his forces to over protect his d4 pawn. Black on the other hand is putting maximum pressure against this square.} 10. O-O Bg4 11. f3 {Black hopes that the Pawn advance to f3 will provide an avenue of attack via the a7-g1 diagonal.} 11... Na5 12. Bxf7+ Rxf7 13. fxg4 Rxf1+ 14. Kxf1 { The pawn is not the most important thing here. For year theoreticians held that this line was harmless, with Black obtaining significant counterplay due to the hole at c4. Karpov has overturned this verdict, at least temporarily.} 14... Qd6 15. Kg1 Qe6 {My queen is well placed on this square. It puts pressure on e4, a2, c4 and g4 squares.} 16. Qd3 Qc4 {Exchanging queens would ease my defensive burden. 16...Qxg4 17.Rf1 For the price of the returned pawn, White would have play on the f-file and the a2-g8 diagonal.} 17. Qxc4+ { If 17. Qd2 then Black plays his Queen to e6 or a6 and threatens the Knight to c4.} 17... Nxc4 18. Bf2 cxd4 19. cxd4 {My queenside pawn majority should insure the possibility of an eventual passed pawn.} 19... e5 {My last move has two points. First it greatly reduces the scope of the White pieces, and if Black can successfully post his Knight on d6, then e4 is very weak. But it gives Karpov a passed pawn, and limits the scope of the Bg7.} 20. d5 Bh6 21. h4 {Karpov tries to cut off the Black bishop with g5.} 21... Bd2 22. Rd1 Ba5 23. Rc1 b5 24. Rc2 Nd6 25. Ng3 Nc4 26. Nf1 Nd6 27. Ng3 Nc4 {A draw from this position would be satisfactory for me. The match score was even at this time, and the position is somewhat equal.} 28. g5 Kf7 29. Nf1 {Karpov wants the full point, but objectively he doesn't have a sufficient advantage to be so ambitious. The extra pawn is the useless one at g2, and the passed pawn at d5 is no threat at all.} 29... Nd6 30. Ng3 Nc4 31. Kf1 Ke7 32. Bc5+ Kf7 33. Rf2+ Kg7 {White tries another avenue of attack but it cannot lead to success because there is no way for the knight to help out.} 34. Rf6 Bb6 35. Rc6 { Karpov somehow failed to realize that the rook is trapped at c6. My next move seals the victory.} 35... Na5 36. Bxb6 { Any move of the rook along the 6th rank would have left the bishop undefended.} 36... Nxc6 37. Bc7 Rf8+ 38. Ke2 Rf7 39. Bd6 { 39.dxc6 Rxc7 I could win this in my sleep!} 39... Rd7 40. Bc5 Na5 41. Nf1 Rc7 42. Bd6 Rc2+ 43. Kd3 Rxa2 { Karpov could have resigned here with a clear conscience.} 44. Ne3 Kf7 45. Ng4 Nc4 46. Nxe5+ Nxe5+ 47. Bxe5 b4 {Passed pawns must be pushed!} 48. Bf6 b3 49. e5 Rxg2 50. e6+ Kf8 0-1
