Mar-27-07 | | euripides: <sheaf> Interesting. I guess the right move order is Kg5-h6 and then g5 (not immediately h4 when black has fxg4 lengthening the diagonal) followed by h4 which does indeed look dangerous. |

Mar-27-07 | | sheaf: damn those spelling mistakes...i hate reading my own posts. |
|
Mar-27-07 | | rankbeginner: Yes, the black king must be prevented from the f5 square. I have a new idea: the computer (WinBoard) found it, but then it floundered after that. After 39 ... Bg6,
white should play
40. Kf4
Black to play:
How can black continue now?

|
Mar-27-07 | | euripides: If Black plays h6 White might try Be5 threatening Bg7. If the king comes to f7 to stop that White could try arranging the c4 break, perhaps bringing his king to d3 to support it. |
|
Mar-27-07 | | rankbeginner: Yes, Euripes, that's a good idea. That's another thing Black must be careful about in this position: the white bishop moving to e5. |
|
Mar-27-07 | | rankbeginner: I'm going to try to win this position against WinBoard: not the strongest chess engine, but all I've got. |

Mar-27-07 | | rankbeginner: Yes, that looks like it's holding, Trog.
White should play 40. Kf4 |
|
Mar-27-07 | | Troglodyte: <rankbeginner> What's the point of 40. ♔f4? show me what you have in mind, black can just play 40... ♗c2 |

Mar-27-07 | | acirce: <However, Anand hit back in the rapid game, where he first won the opening battle and then a highly promising endgame. In a Marshall Gambit of the Ruy Lopez, Aronian believed that he was fine after 21…Nd5, at least that was what his second in Linares, Vladimir Potkin had told him. Anand begged to differ. He had studied the line as well and had stopped after 25.Bxg5 with the conclusion that White was much better. Perhaps Aronian could have defended better in the opposite-coloured bishops endgame, but as it Anand coolly hauled in the point after 57 moves.> http://www.amberchess.com/2007Round... |

and white wins |

Mar-27-07 | | Troglodyte: <rankbeginner> Ok.. the computer just made a blatant blunder with 55... ♗a2(??) when it could have just moved his King around. |
|
Mar-27-07 | | Ulhumbrus: White has two ways to attack Black's side of the position in the ending. One way consists of the potential threat of c4!! and the other consists of an endgame attack on the King side. It may be that an attempt to defend the potential threat of c4 hinders fatally Black's defence on the King side, while an attempt to defend the King side reduces fatally Black's ability to defend against the threat of c4. Thus White combines the threat of c4 with a King side attack so that in defending one threat Black is handicapped fatally in the way of defending the other. The potential threat of c4!! suggests that the way to win an ending of opposite coloured bishops is to find a diabolical combination. |

Mar-27-07 | | Justawoodpusher: Hello <rankbeginner>, I tried the same idea as <Troglodyte>, 40...Bc2 and found no convincing way for white to win up to now. Black just plays waiting moves with the bishop till white advances the g pawn. This black has to take. Afterwards black has to make sure that the white king doesn't reach the queen side. |
|
Mar-27-07 | | micartouse: The Marshall has always been known among GMs as Anand's personal property. Do not trespass. |
|
Mar-27-07 | | KamikazeAttack: I agree. Anad really understands the Marshall. So does Michael Adamns. |
|
Mar-27-07 | | Marmot PFL: So does Kramnik, and Aronian. Anand must take these rapid games seriously if he shows one of his opening discoveries. |
|
Mar-27-07 | | sheaf: <marmot pfl> 21.. ND5 was part of aronians preparation, it just happenend that anand had also studied this position. |
|
Mar-27-07 | | rankbeginner: Troglodyte and Justawoodpusher:
You are right: the computer blundered and let white win easily. With best play, there is no easy way to break through.
I'm going to look more at this, and let you know if I find a win. I still have a feeling that there might be something subtle in that position.I might also try to get a better chess engine: something like Crafty.
Thanks for your input! ... RB |

Mar-27-07 | | scacchi: It's very, very , really very hard to stop Anand when, in an apparent nivelated game, he decides to take the initiative. |
|
Mar-28-07 | | ahmadov: In this game Aronian had managed to escape a loss...
Anand vs Aronian, 2007 |
|
Mar-28-07 | | Ulhumbrus: In the final position on 57...h5 58 Kd3 Ke6 59 b5 axb5 60 a6 the a pawn cannot be stopped, and White wins. |
|
Mar-29-07 | | Major Dude: I would have loved to see Anand play Fischer rapid chess. |
