49... h3? This complicates matters considerably, but the win is not gone yet. Much better is 49... Bd5! threatening immediate mate, and if 50. gxh4 then crispest is 50... f4! and mate cannot be avoided. 50. Ra6+! And now Black has to step carefully to avoid stalemate. 50... Kf7 51. Rf6+ Ke7 52. Re6+ Kd7 53. Rd6+ Kc7 54. Rc6+ Kb7 55. Rc7+ Kb8?? Now the win is gone. It was essential to play 55... Ka8! 56. Ra7+ (56. Rc8+ Rb8) 56... Kb8 57. Ra8+ (57. Rb7+ Rxb7) 57... Kc7! and the king escapes: 58. Rc8+ Kd6 59. Rd8+ Kc5 60. Rc8+ Kd4 61. Rd8+ Kc3 62. Rd3+ Kc2 63. Rc3+ Kb1. 56... Ka7 comes to the same thing after 57. Ra8+ Kb6 58. Rb8+ 57. Rb8+ And now Black must give up a rook to avoid stalemate. 57... Kxb8 In fact Black wouldn't risk much after 57... Kc6 58. Rxb2 Bd5 , but there is no way of breaking through 1/2-1/2 |
