[Event "Belgrade"] [Site "?"] [Round "21"] [White "Fischer"] [Black "Spassky"] [Result "1-0"] [ECO "B32"] [Opening "Sicilian: Open, 2...Nc6"] 1. e4 c5 2. Nf3 Nc6 3. d4 cxd4 4. Nxd4 e6 5. Nb5 d6 6. c4 Nf6 7. N5c3 Be7 8. g3 {This seems to be a new idea. The bishop is usually developed at e2.} 8... O-O 9. Bg2 a6 10. O-O Rb8 {This prepares a break with b7-b5, which had to be delayed because of pressure on the long diagonal.} 11. Na3 Qc7 { 11...b6 is a more convincing defence, setting up a hedgehog.} 12. Be3 Bd7 13. Rc1 {White is setting up threats of Nb5 and Nd5.} 13... Ne5 14. h3 Rfc8 15. f4 Ng6 { This is not the normal position for a knight in this setup, but it is playable. } 16. Qd2 {16.f5 Ne5 would provide Black with a useful outpost.} 16... Be8 { 16...b6 might be better played immediately.} 17. Rfd1 b6 18. Qf2 h6 19. Kh2 { A useful waiting move in a position in which no immediate action is useful.} 19... Qa7 {The idea is to prepare to establish a battery on the long diagonal with Bc6 and Qb7.} 20. Qe2 Qc7 {Perhaps Spassky decided that Nc3-d5 was no big deal, but in any event 20...Bc6 would have been a useful move.} 21. Bf3 Bc6 22. Nab1 Qb7 23. Nd2 b5 24. cxb5 axb5 25. b4 {It is necessary to stop Black's b-pawn from advancing and taking control of valuable territory.} 25... Qa8 { Now that there are weaknesses on the a-file, this is a good place for the queen. 25...Ra8 also comes into consideration.} 26. Rc2 d5 {This is gener ally a strong strategic move in the Sicilian, but there was an interesting alternative in 26...Qa3!?} 27. e5 Ne4 28. Bxe4 dxe4 29. Bc5 {This is very strong, achieving the strategic goal of closing the c-file. Spassky now counts on the pressure on the long diagonal and his active pieces.} 29... Bxc5 30. bxc5 Rd8 31. Re1 {31.Ndxe4? Rxd1 32.Qxd1 Bxe4} 31... Ne7 { The knight prepares to occupy d5.} 32. Ncxe4 Nf5 { 32...Qa4 is an interesting option, leading to unclear complications.} 33. Nb3 Nd4 34. Nxd4 Rxd4 35. Nd6 Qa4 36. f5 {An important thrust!} 36... Ra8 37. Rb2 Qa3 {This is better than 37...Rb4.} 38. fxe6 fxe6 39. Nxb5 Bxb5 40. Qxb5 Rd3 { Spassky targets g3.} 41. Rg2 Qc3 42. Ree2 Ra3 43. Rc2 Qxe5 44. Rce2 Re3 45. Rxe3 Rxe3 46. a4 Rc3 47. c6 Qd6 {The c-pawn just marches along...} 48. c7 Rxc7 {This is the decisive mistake. Black should have played 48. ..Qxc7 49.Qe8+ Kh7 50.Qxe6 and tried to grovel in the endgame.} 49. Qb8+ Kh7 50. a5 h5 { 50...Rc6 51.Qxd6 Rxd6 52.Ra2 Ra6 53.Kg2 and White will win.} 51. h4 Qc5 52. a6 Rf7 53. Qb1+ Kh6 54. Qa2 Re7 55. Qd2+ Kg6 56. Re2 Kh7 57. Qc2+ Qxc2 58. Rxc2 Kg6 59. Ra2 {Simple technique brings the game to a close.} 59... Ra7 60. Ra5 e5 61. Kg2 Kf6 62. Kf2 Ke6 63. Ke3 Kf5 64. Kf3 g6 65. Ra3 g5 66. hxg5 Kxg5 67. Ke4 1-0
