|Oct-03-05|| ||Chan: "There I played what was evidently the first successful ending in my life. Everyone thought the bishop ending where I was a pawn up would be a draw, but we managed to find an interresting bishop manoeuvre which gave White a forced win"

|Sep-09-10|| ||sisyphus: This game was apparently played in the final match of the USSR youth team championship in Chisinau, Moldova. |
In "The Life and Games of Mikhail Tal," he gives the score after 44.Kf3, which I imagine was sealed before adjournment. Tal provides two brief annotations: <57.B-K2 Zugzwang!> and <60.B-K2 The bishop finishes its dance.>
For the life of me, though, I can't see how Black's position is much worse after the 57th move. My friend Fritz seems to believe 61...Kf6 was the losing move, whereas 61...Kd6 would have held.
|Dec-12-10|| ||misha1992: Looks like 61...kd6 is answered by 62.Bd1 with black to move his bishop on the a8 and h1 diagonal or staying on the a4 e8 diagonal or moving his king c7, d7,e7, d5 or e5. All bad choices, bishop staying on a8 h1 besides f3 drops pawn a4 to king. Bishop stays a4 e8 bishop takes a4 pawn. Any king move besides 62....Kd5(Bf3+) Kd7(Bxa4) white moves 63.Kc5. 62...Kc7 63.Kc5 leaves black choosing choosing which piece to allow white force in the pawn. 63....Kd7 64.Bb5. 63....Kb7 64.Kd6 and whites king and pawn beat the bishop. While moving the bishop on the a8 h1 diagonal allows two wins after B-a8, b7, g2 or h1. 65.Bb5 allowing black to have a pawn or move the king back.65....Bf3(h3) 66.f6 Bxg4 67.f7 and queens. 65.Bb5 Be4 66.Bxa4. If 65.Bb5 Kd8 67.Kd6 followed by promotiom, Bxa4 or both.|
Back to 61....Kd6 62.Bd1. Blacks king now has 62...Ke7(e5) both answered by 63.Kc5 making the bishop choose between staying on a4 e8 diagonal or a8 h1 diagonal both bad where ever the king chooses to go. 62....Ke5 63.Kc5 Bd7(e8) 64.Be2 and blacks a4 pawn falls by 65.Bb5 or 64....Kf4 65.Kd6 and whites king and pawn beat bishop. 63.Kc5 B any (besdes f3) 64.Kb5 and the pawn falls. And finally 62....Ke7 63.Kc5 leaves blacks bishop choosing how to lose the pawn 63....Bd7 64.Kb6 and 65.Bb5. 63....Be8 64.Be2-b3.
All lost for black after 61....Kd6.
Hope this helps it was fun learning this ending!
|Dec-12-10|| ||misha1992: Made mistake 61....Kd6. 62.Bd1 Kc7 63.Kc5 draws because I had the B on d1 not e2 duh! 62....Kc7 63.Bxa4 63....Bf3 64.f6 Kd6 65. f7 Ke7 66.Bd7 Kxf7 and draws after the black king marches back to kingside.|
|Apr-04-17|| ||madmartigan1: I don't see why black must defend both the a8h1 diagonal and the a4d8 diagonal .. this is certainly the case if his pawn is already on a4 but if black leaves the pawn on b5, puts his king on d6, the bishop can just go back and forth on the a4e8 diagonal. White cannot make any progress. Black just needs to prevent the king from getting to a4/b5 or move to the d1h5 diagonal if the white Bishop ever leaves it. Seems like Blacks mistake was 60. a4+|
