1. e4 c5 2. Nf3 e6 3. d4 cxd4 4. Nxd4 a6 5. Bd3 Nf6 6. O-O Qc7 7. Be3 d6 8. c4 g6 9. f4 Bg7 10. h3 O-O 11. f5 Nc6 12. Nxc6 bxc6 13. Nc3 Rb8 14. Rb1 c5 15. Qd2 Bb7 16. Bh6 Bc6 17. Bxg7 Kxg7 18. Rf2 Nd7 19. Rbf1 Ne5 20. f6+ Kh8 21. g4 Rg8 22. g5 h5 23. gxh6 Kh7 24. Rg2 Qd8 25. Qe3 Qf8 26. b3 Qxh6 27. Qe2 g5 28. Nd5 Bxd5 29. exd5+ Kh8 30. dxe6 fxe6 31. f7 Rgf8 32. Rf6 Qh4 33. Rxe6 Nxd3 34. Qxd3 Rxf7 35. Qxd6 Qd4+ 36. Qxd4+ cxd4 37. Rh6+ Kg7 38. Rxa6 Re8 39. Rxg5+ Kf8 40. Rg2 Re1+ 41. Kh2 d3 42. Ra8+ Ke7 43. Ra7+ Kf8 44. Rxf7+ Kxf7 45. Kg3 Re3+ 46. Kf4 Re2 47. Rg3 Rf2+ 48. Ke4 d2 49. Rd3 Rh2 50. a4??

It turns out that White still has a winning position after this, but it all becomes harder.

50... Rxh3! 51. Rxd2 Rxb3 52. c5

52. Ra2 is simpler.

52... Ke7 53. Kd5 Ra3 54. Rd4 Kd7 55. Rb4?

Only this lets the win slip. 55. Rf4, 55. Rg4, and 55. Rh4 are the only moves that win (Nalimov tablebases).

55... Kc7= 56. Kc4 Kc6 57. Rb6+ Kc7 58. Rb4 Ra1 59. Kb5 Rc1?

Now White would be winning again after (59... Rc1) 60. a5.

59... Kb7 draws, as does R to anywhere from d1 to h1.

1/2-1/2
