[Event "World Championship"] [Site "?"] [Round "18"] [White "Kasparov"] [Black "Karpov"] [Result "1-0"] [ECO "C70"] [Opening "Spanish: 4.Ba4"] 1. e4 e5 2. Nf3 Nc6 3. Bb5 {I switch back to the Spanish Game. Karpov responded quickly with a new pawn sacrifice.} 3... a6 4. Ba4 Nf6 5. O-O Be7 6. Re1 b5 7. Bb3 d6 8. c3 O-O 9. h3 Nd7 10. d4 Bf6 11. a4 Bb7 12. Na3 exd4 13. cxd4 {We had been here before, in the final game of the New York leg.} 13... Nb6 14. Bf4 {Best!} 14... bxa4 15. Bxa4 Nxa4 16. Qxa4 {Black has gotten rid of the famous "Spanish bishop", but aside from that he hasn't done much. My pieces occupy better squares. He has no good squares under control, so now he takes over b4 for his knight.} 16... a5 17. Bd2 Re8 18. d5 Nb4 19. Bxb4 { So much for the big square! Well, Karpov has the bishop pair, but the one at b7 certainly doesn't impress.} 19... axb4 20. Qxb4 Rb8 21. Qc4 Qc8 22. Nd4 Ba6 23. Qc3 {OK, so now he has both bishops working as compensation for the pawn and miserable pawn structure. And I am going to make something of the pawn!} 23... c5 { 23...Rb6 24.Nac2 Qb7 25.b3 Bb5 This would have been a tougher nut to crack!} 24. dxc6 Bxd4 25. Qxd4 Qxc6 26. b4 {Here we go!} 26... h6 27. Re3 Re6 28. f3 Rc8 29. Rb3 { Having secured the kingside I can give the queenside my undivided attention.} 29... Bb5 30. Rb2 Qb7 31. Nc2 Qe7 32. Qf2 Rg6 33. Ne3 Qe5 34. Rbb1 {These retre ats are justified by the fact that I must eliminate all counterplay before returning to the advance of the b-pawn.} 34... Bd7 35. Ra5 Qe7 { Maybe 35...Qd4 would have provided more resistance.} 36. Ra7 Qd8 37. Nd5 Kh7 38. Kh2 Rb8 39. f4 Re6 40. Qd4 Qe8 {Here I sealed my move and went home. The rest of the game was simple and I wrapped it up quickly the following day.} 41. Re1 Bc6 42. Qd3 Qf8 43. Rc1 Bxd5 44. exd5+ Rg6 45. Qf5 Kg8 46. Rac7 Rf6 47. Qd7 Rd8 48. Qxd8 Qxd8 49. Rc8 Qf8 50.
