  1. Kb7 a6! (but not 62...b5? 63. K×a7 b4 64.Bc4 Nb5+ 65.Kb8=) 63. B×a6 Nb5!-+ with decisive zugzwang! 50. K×h4 Nf5+ 51.Kg4 N×e3+ 52.Kf3 Nd5 53.a5! The simplest, although 53.Ke4 Nc3+ 54.Kd4 is also sufficient to draw.
  2. ba 54.Ke4= Kd6 55.Kd4 Nf6 56.Bb7 Kc7 57.Bf3 Kb6 58.Kc4 Nd7 59.Be2 Nc5 60.Kc3 Ne4+ 61.Kb3 Kc5 62.Bd3 Nd2+ 63.Kc3 Nf3 64.Kb3 Nd4+ 65.Ka4 Kb6 66.Ka3 Ne6 67.Bc4 Nc5 68.Bf1 Kc7 69.Be2 Kd6 70.Bc4 Ke5 71.Be2 Kd4 72.Bf1 Draw.
  3. Qd2+? Re2 58.Qd6 (no better is 58.Qg5 Ree3=) 58...R×e6! White, of course, overlooked this shot. The capture of the rook leads to perpetual check: 59. Q×e6 R×g3+ 60.Kh2 Rg2+, etc.
  4. D) In the game there followed 54.Qe6+? Kh7 55.Qd7+ Bg7 56.Kf2 Qh4+ 57.Ke2 Qf6/-+/.
  5. Black's king is sheltered from checks; Levon Aronian ultimately realized his extra pawn. But here in the line 54.Bd6‼ B×d6 (54...Bg7 55. B×c5=) 55.Qe6+ Kh7 56.Qd7+ Kg8 (alas, not 56...Kh6⁇ in view of 57.g5+) 57.Qe6+ the matter would end with perpetual check. 167. Kamsky -Aronian Wijk aan Zee 2006 168. Leko -Khalifman Istanbul ol 2000
  6. As in the previous example, the possibility of forcing a draw by perpetual check by tactical means went unnoticed. The grandmaster chose another continuation and eventually lost. Black is saved by 56...Bb5‼ (with the threat of 57...Bc4+) 57.ab R×b5+ 58.Ka4 (58.Kc2? Re2+) 58...Ra5+. In the game there followed 56...Re4? 57. N×d7 K×d7 58.R×h4±. counterproductive: 38.R×e5+⁇ R×e5 39. B×e5 K×e5 40.Kg3 Kd4-+.
  7. An inexplicable delay. There was an elementary win after 47.Kf6 Ke3 48. B×g6. 47...Ke2 48.Kg5 Here the game was adjourned. Black, after thinking for ten minutes, sealed a move. The natural 48...Kf3 would lead to an easy draw: 49. B×g6 Bd7 50. B×h5+ K×g3 51.Bg6 (51.Bd1 Be8=) 51...Bg4=.
  8. However Dragutin Sahovic sealed 48...Kf2⁇, but then resigned without resuming in view of 49. B×g6 Bd7 50.Kf4! Bg4 51.Bf5 (also strong is 51. B×h5 B×h5 52.g4 Bf7 53.h5+-) 51...Bd1 52.g4 hg 53. B×g4 Bb3 54.h5+-.
  9. Sandor -Szily Hungary ch 1953 53...Kd2⁇
  10. An absurd move, since after winning the rook for the e-pawn, the king will have to go back and every tempo may turn out to be decisive. More to the point was 53...Kd3! 54.Kg3 (nothing is changed by 54.Rd5+ Ke4! 55.Rd8 e2 56.Re8+ Kd3, and on 54.Kf3 there follows 54...Rf1+) 54...e2 55.g5 e1Q+ 56.R×e1 R×e1 57.Kf4 Kd4 58.Kf5 Kd5 59.Kf6 Kd6 60.g6 Rf1+. 54.Kg3 The error of Black's previous move could also shown by 54.Rd5+ Ke2 (54...Kc3 55.Kf3=) 55.Kg3= or 55.g5=.
  11. As Jonathan Mestel noted, there was still a draw after 42.Rd6 or 42.Rc6. Worse is 42.Rg7+⁈ Kd8 43.R×a6 Re7 44.Rd6+ Ke8 (44...Kc8? 45.R×e7 g3 46.Rd2! B×d2 47.R×e4+-) 45.Rg8+ Kf7 46.Rh8. (D)
  12. Kg7 (the hasty 46...g3? is wrong: 47.g6+ Kg7 48.Rh7+ Kf8 49.Rd8+) 47. Rdh6 g3 (but not 47... B×g5? 48.R8h7+ Kf8 49.R×e7 B×e7 50.Re6 g3 51.b4+-) 48.R8h7+ Kf8 49.Rh8+ Kf7 50.R8h7+ (there is nothing else better: 50.Rh2 Rd7; 50.Ke1 g2; 50.g6+ Kf6 51.g7+ K×g7 52.R8h7+ Kg8 53.Rh8+ Kf7 54.R8h7+ Ke8 55.R×e7+ K×e7 56.Rg6 Bf2) 50...Ke8 51.Rh8+ Kd7 52.Rh2 Kc7 53.Rc2 Rd7-+ (analysis from British Chess Magazine, 1999/8). White sealed the move 42.Re6+?. -Prior to the resumption of play, the noted Soviet GM told his opponent, that his sealed move was 42.Re6+ and confidently rattled off the following "forced" variation: 43...Kd7 43.R×e8 (43.Rc6 Re5) 43... K×e8 44.Re6+ Kd7 45.R×e4 and White wins. Indeed this position is won, yet GM Kotov undoubtedly knew that instead of 43... K×e8⁇ Black can play 43...g3‼ and it is Black who wins. However, GM Kotov's ploy worked: Lambert saw no reason to doubt the honesty of the GM's variation and therefore resigned! (Edmar Mednis).
  13. Kc4 Kc6! Hopeless is 64...Re5? 65.Kd4! Rb5 (65...Re4+ 66.Kd5 R×b4 67.Ke6+-) 66.Rc3! R×b4+ (on any king move it is possible to reply 67.Rc5) 67.Ke5 Rb5+ 68.Ke6. 65.Rb3 Great precision in defending is demanded in the line 65.Re3⁉ Rd8! 66.b5+ Kb6 67.Rf3 (67.Re6+ Kb7 68.Kc5 Rf8⁉ 69.Re7+ Kb8, with the idea of 70...f4=, is not dangerous) 67...Rg8! 68.Kd5 K×b5 69.Ke6. On 69...Kc5? White wins, though not without some difficult: 70.Kf7! Rg4 71.Kf6 Kd5 (71...Rg8
  14. R×f5+ Kd6 73.Rg5+-; 71...Kd6 72.Rd3+ and 73. K×f5+-) 72. K×f5 Rg8 73.Rd3+! Kc4 74.Ra3! Kb4 75.Rf3 Rf8+ 76.Kg4! Rg8+ 77.Kh5 Kc5 (77...Rh8+
  15. Kg6 Rg8+ 79.Kh7 Rg5 80.Rf4+ Kc5 81.g4 Kd6 82.Kh6+-) 78.g4 Rh8+ 79.Kg6 Rg8+ 80.Kf5 Kd6 (80...Rf8+ 81.Ke4 Rg8 82.Rf5+ Kd6 83.g5+-)
  16. Rd3+! Ke7 82.g5, and Black cannot avoid Lucena's Position. Only 69...Kc4‼ saves the game: 70.Kf7 (70. K×f5 Kd4 or 70...Rf8+ 71.Kg4 Rg8+)
  17. Rg5! 71.Kf6 Rg8=, and White cannot eliminate the pawn on f5 with check, as after 69...Kc5?. 65...Re5 Also possible is 65...Rd8⁉. 66.b5+ Kb6 67.Kd4 67...Re4+? The decisive error. The white king should not have been allowed to advance. After 67...Rc5! the win is not obvious: 68.Ke3 Rc4 69.Kf3 Rg4 70.Rb1 Rc4, or 68.Rb1 Rc2! (transferring the rook to f2 is the only way to secure the f5-pawn) 69.Ke5 Rf2 70.Rb3 Rf1 71.Kf6 Rf2 72.Kg5 Rf1.
  18. Kd5 Re8 69.Kd6 (69.Rf3) 69...Re1 70.Rf3 K×b5 (the more stubborn 70...Re8 71.R×f5 Rg8 72.Rf3 K×b5 also does not save Black: 71.R×f5 Rg8 72.Rf3 K×b5) 71.R×f5+ Kc4 72.g4 Kd4 73.g5 Rg1 74.Ke6 Ke4 75.Kf6 Ra1 76.g6 Ra7 77.Re5+ Kf4 78.Re7 Black resigned. 317. Romanishin -Anand New York cm (7) 1994
  19. Black's only hope to make any progress lies with h7-h5 and, if necessary, Rh6. As Viswanathan Anand noticed, this could have been prevented rather easily by 73.Rc8! h5 (if 73...Kb7, then at least 74.Rh8 h6 75.Ke5 Kc6 76.Rh7 Kc5 77.Re7=) 74.Rh8 Rg5 75.Rh6!=. Poldauf 23
