1. c4 c5 2. Nf3 b6 3. b3 Nf6 4. e3 Bxf3. Black unnecessarily gives up the Bishop-pair, just to inflict a little damage on White’s Pawn structure. A normal course as 4. ... e6 5. Be2 Be7 looks more reasonable. 5. gxf3 g6 6. Nc3 Bg7 7. Nd5 d6 8. Nxf6+ Bxf6 9. Bxf6 exf6 10. Qc3 Qf5. “Commentators called this a ‘typical Fischerandom move’. Not a naturaò move, but 10. ... Nd7 would fail to 11. Bh3”, Grandmaster Svetozar Gligorić wrote in his book “Shall We Play Fischerandom Chess?”, London, Batsford, 2002, page 117. 11. f4 0-0 12. Bg2 Na6. Nobody could tell it is a game of Fischerandom Chess! 13. 0-0 Nc7 14. d4. “White is first to make the Pawn break in the centre, and it offers him a lasting initiative”, Gligorić wrote (op. cit., p. 118). 14. ... Ne6 15. dxc5 dxc5 16. Rd5 Rxd5 17. cxd5 Nc7 18. Qc4 Ne8. “The absence of Black’s Queen on the sensitive a-side is felt. So Black should have tried 18. ... Qd7!, despite the possibility of the unpleasant break b3-b4”, Gligorić wrote (op. cit., p. 118). 19. Qa4. Now one of the Black’s Pawn on the a-side immediately falls, since 19. ... a5 would fail to 20. Qc6. 19. ... Qc8 20. Qxa7 Qd8 21. a4 f5 22. a5 bxa5 23. Qxc5 Nd6 24. Ra1 Qb8 25. Qxa5. There is no choice because 25. Rxa5 Nb7 would cost the Exchange. 25. ... Qxb3 26. Qc5 Qb8 27. Bf3 Rc8 28. Qd4 Qc7 29. Ra6 Qd8 30. Qb4. “30. Qe5 Nc4 would be ineffective in breaking the blockade. An attractive but unclear alternative was 30. Rc6”, Gligorić wrote (op. cit., p. 119). 30. ... Ne8


31. d6. The sharpest continuation! 31. ... Qd7 32. Be2. This seems to be a careless move which dissipates a skillfully earned superiority. The correct route is 32. Bd1! Rd8 33. Ba4 Qc8 34. Rb6! with Black being squeezed out of the game. 32. ... Rd8 33. Bb5 Qb7. This is the saving clause. 34. Qc5. On 34. Qa5 Rxd6 35. Ra8? (both 35. Rxd6 Nxd6 and 35. Qa4 Qd5 would lead to a draw) 35. ... Rd1+ 36. Bf1 Qf3! 37. Rxe8+ Kg7 38. Qa6 Rd2 39. Qa1+ Kh6 40. Qe1 Qg4+ 41. Kh1 Rd1 42. Qxd1 Qxd1 43. Kg2 Qg4+ 44. Kh1 Qf3+ 45. Kg1 Kg7 Black gets a significantly better position. Another try is 34. d7 Rxd7 35. Qa4 Rd6 36. Ra7 Qf3 37. Be2 Qc6 38. Qxc6 Rxc6 39. Ra8 Kf8 40. Bb5 Re6 and Black’s fortress looks secure. 34. ... Rxd6 35. Rxd6 Nxd6 36. Qxd6 ½ : ½.
