[Event "Belgrade"] [Site "?"] [Round "13"] [White "Fischer"] [Black "Spassky"] [ECO "B31"] [Opening "Sicilian: Rossolimo, 3...g6 4.Bxc6"] 1. e4 c5 2. Nf3 Nc6 3. Bb5 g6 4. Bxc6 bxc6 5. O-O Bg7 6. Re1 f6 { Here Spassky deviates from game 11, where 6...e5 7.b4! proved problematic.} 7. c3 {Preparing a classical central advance. 7.b3!? comes into consideration, and seems more appropriate for the position, given Black's doubled pawns.} 7... Nh6 8. d4 cxd4 9. cxd4 O-O 10. Nc3 d6 {Black's position has a couple of holes on the light squares, but these do not seem to be serious weaknesses.} 11. Qa4 {This allows Black to exchange queens almost by force, which gives him a comfortable position. 11.Qc2 seems more promising.} 11... Qb6 12. Nd2 { An ugly little move, which hopes to drive Black's queen from its strong position. 12.h3 Nf7 13.Be3? Qxb2 14.Qxc6??Bb7} 12... Nf7 13. Nc4 Qa6 { 13...Qxd4?? would be a horrible blunder: 14.Be3 Qd3 15.Rad1 and the queen is lost.} 14. Be3 Qxa4 15. Nxa4 f5 { This essential move activates Black's bishop pair.} 16. exf5 {16.f3 fxe4 17. fxe4 Bd7 gives Black a fluid position with a great deal of counterplay.} 16... Bxf5 {16...gxf5 is an interesting alternative.} 17. Rac1 Rfc8 {This is a dynami cally balanced position, with each side having to worry about a weak pawn (d4, c6).} 18. Na5 Bd7 19. b3 Rab8 20. Nc3 Kf8 21. a3 Nh6 {The knight will be transferred to a strong position at f5. 21...c5 22.dxc5 dxc5 23.Nd5! is clearly favorable for White.} 22. b4 Nf5 23. Red1 Ke8 {23...Nxe3 24.fxe3 Bh6 25.Kf2 gives Black two bishops against two knights, but the bishops lack natural targets.} 24. Ne4 Rb5 { Spassky realizes that the knight on f5 is a major asset.} 25. h3 h5 { Black does not want the horse to be chased away!} 26. Rd2 a6 27. Kf1 Rd5 28. Rcd1 Rb5 {The position is fully equal and the rest of the game contains mostly minor thrusts and parries of little interest.} 29. Ke2 Be6 30. Rc1 Kd7 31. Nc3 Rbb8 32. Kf1 h4 33. Ke2 Bf6 34. Ne4 Bd5 35. Kd3 {35.Nxf6+ exf6 36.f3 Re8 37. Rd3 Nxe3 38.Rxe3 Rxe3+ 39.Kxe3 Re8+ gives Black better chances, because the Na4 is dominated by the Bd5.} 35... Bg7 36. Rdc2 Rc7 37. Re1 Rf8 38. f3 Rb8 39. Nc3 Bg8 40. Ne2 Bf7 41. Bd2 Bf6 42. Rec1 Rbc8 43. Nc4 { This threatens Nb6+ and brings the game to a drawn conclusion.} 43... Rb7 44. Na5 Rbc7 45. Nc4 Rb7 *
