14. 0-0 Rfc8 15. Rfc1 Qd8 16. Nb5 Nd7 17. Kh1 Nc5 18. Qe3 Qf8

19. Rd2? Now, for the sake of Black’s dark-squared Bishop, all White’s heavy places are on the same diagonal. 19. Rd1 was obviously better.
19. ... Bd7 20. Nc3? Another mistake, skewering himself. Best was 20. Qg1! Bxb5 21. cxb5 a3!⩱ leaving Black with a slightly superior game.
20. ... Ne6 21. Nd5. This implies the loss of the Exchange, but 21. f4 f6 22. Bh4 Nxf4! was not appealing either.
21. ... Nxg5 22. Qxg5 Bh6 23. Qxe7 Bxd2 24. Rd1 Be6 25. Qxf8+. 25. Rxd2 Bxd5 transposes to the game.
25. ... Kxf8 26. Rxd2 Bxd5 27. Rxd5 Rc6. The ending should be winning for Black.

28. Kg1 Rb6 29. Rd2 a3 30. bxa3 (30. b3? Rxb3!−+)
30. ... Rxa3 31. Bd1 Ke7 32. Bb3 Ra5 33. Re2 Re5 34. f4 Rc5 35. Kf2 g5 36. f5 Kf6 37. Ke3 Ke5 38. Kd3 Ra6 39. Rf2 h6 40. Ke3 Ra3 41. Rd2 Ra6 42. Kd3 Rac6 43. Ba4 Rc7 44. Bb5 Re7 45. Ke3 Rec7 46.

68. ... Rxb3+. Finally Black returns the Exchange, forcing what should be a winning Rook endgame.
69. Kxb3 Rxe4 70. Rd5+ Kc6 71. Rd2 Rf4 72. Kb4 Rxf5 73. a5 Rf4 74. h3 f5 75. Kc3 g4 76. hxg4 fxg4 77. Rd5

77. ... Rf2? 77. ... g3! 78. Rh5 Rf3+! gains a crucial tempo on the King, winning by force.
78. Rh5 Rxg2 79. Rxh4 g3 80. Rg4 Rg1 81. Rg5 g2 82. Kb2. Of course. Now it’s a draw.
82. ... Kd7 83. Rg3 Ke6 84. Rg5 Kf6 85. Rg8 Ke5 86. Rg4 Kf5 87. Rg7 Ke4 88. Rg6 Ke3 89. Re6+ Kf4 90. Rg6 Ke4 91. Ka2 Rc1 92. Rxg2 Rxc4 93. Kb3 Rc5 94. Kb4 Kd5 95. Rg5+ Kd4 96. Rg4+ Kd3 97.
