80... Kc7 |
Didn't see it, or maybe he didn't want it. Now black gets put on the back rank. | ||||||||
| | |||||||||
|
81. Rb7+ Kc8 |
Note that White has to guard against Rxe4 , which will allow black to take the white rook! | ||||||||
| | |||||||||
|
82. Rg7 Rd1 83. Bd5 Rc1 84. Kd6 |
Black's king is becoming very restricted, but he only needs to make it through move 96 for the draw... | ||||||||

84... Kb8 |
Accurate; other moves allow mate or lose material. | ||||||||
| | |||||||||
|
85. Rb7+ Kc8 86. Ra7 |
Threatening mate with Ra8#; black's response defends against this threat but misses the other one... | ||||||||
| | |||||||||
|
86... Rb1 |
?? After all his great play, this blunder costs black the game in dreadful fashion. The last hope was Kd8!, leading to the famous "philidor position" in the R B vs. R, which is a win for the strong side, but it takes something like 13 or 15 moves to do it in -- enough for black to hold on here! | ||||||||

87. Rf7 |
And there's no good defense now! Running with 87. ...Kb8 leads to 88. Rf8 Ka7 89. Ra8 Kb6 90. Rb8 , winning the rook, and there's nowhere for the rook to move to defend against Rf8# without losing material. | ||||||||
| | |||||||||
|
87... Rb6+ |
As good a try as any, but easily parried. | ||||||||
| | |||||||||
|
88. Bc6 |
There's no hope for a stalemate, either. The line is very simple from here... | ||||||||
| | |||||||||
|
88... Kb8 |
Running doesn't help for anything but a single move. | ||||||||
| | |||||||||
|
89. Rf8+ |
And black resigns, for it's a mate in 1 after 89. Rf8 Ka7 90. Ra8#. This endgame almost never comes up, but it was fun to learn about it and awfully exciting to win from the strong side! To those of you who stuck with it, thanks for your fortitude, and I hope you enjoyed it! -Ethan | ||||||||
