| Jul-03-06 | | thatsmate: Can someone explain to me why 57. ...Kf8 doesnt draw/ win for black? I see 57. Kf8. Now white can't move his bishop and pushing the pawn would be stupid, so white's king must move, say 58. Ke8. Black responds with 58. ...h3. Then white has no realistic other choice but to push his pawn, so 59. f7, leading to 59. ...a3. Then white is at a loss- it cannot move any of its peices without losing. What am I not seeing? |

 | | Honza Cervenka: <I see 57. Kf8. Now white can't move his bishop...> Of course, he can move his Bishop on b1 and a2. It is sufficient. Black will run out with Pawn moves pretty soon. The game could continue 57...Kf8 58.Kg6 h3 59.f7 a3 60.Bb1 a2 (or 60...Ke7 61.Kg7 and 62.f8=Q) 61.Bxa2 b1=Q+ 62.Bxb1 Ke7 63.Kg7 etc. |

 | | al wazir: Placing the ♗ on a2 where it could both block black's Q-side ♙s and control f7 and g8 was ingenious, but I don't think it's necessary. Keeping it on the f1-a6 diagonal is sufficient to win. |

| Mar-13-20 | | jith1207: <Keeping it on the f1-a6 diagonal is sufficient to win>: I don't think I get this. How will that help prevent Black's a3 pawn from promoting to a queen? |

| Mar-13-20 | | lentil: I was thinking 45 ... e5 to swap off the W f-pawn and leave W with the wrong-colored rook pawn. (46 fe Kxe5) but 46 f5 e4 47 Bb7+ Ke5 48 Bxe5 and I think the W king can hold the pawns; he can abandon the B because if Black captures it, the W f-pawn is free. |

 | | scutigera: <thatsmate>: Unlike generic versions of this endgame, White can play Kg6 and win because Black can't play Kg8, thanks to the bishop on a2. To fend that off, Black has to pitch the b-pawn, after which White captures it and moves back to a2, blocking Black's a-pawn. White's K will then penetrate on the g-file, unless Black tries a stalemate defense by running to the h-file while White's bishop is busy, in which case White can penetrate on the e-file instead. |
