re:Famous Alekhine-Capablanca game 40. Rb6! - Why wins? - 2006/11/27 13:16
After 40. Rxb6 ab 41.Rb7 Bc7 the white rook is completely imobilized.
White threatens to bring his king up and win it. Black can only stop this plan by bringing his king to the queenside, as well. Now, the black king gets there, first, and then white will play hxg4 h(or f)xg4 g3!--now all the black pawns are immobilized.
White can then use his b-pawn to seize the opposition, at which point black will have to allow either a decisive king infiltration on the kingside, or allowing the white king to gobble the black rook.
Black can avoid this only by giving back the exchange at the right moment: (after 41.Bc7) And I'm doing this without a board, so forgive a mistake here) 41.... Ke7 42.Kd3 Kd7 43.Kc4 Rxc7 44.bc Kxc7 45.Kc6!
White takes the opposition, which he can hold regardless of black's pawn moves (e.g. a5, b3; f4, h3; h3, f3 etc) and black has to allow a decisive penetration on the kingside or the loss of his a-pawn.
Or, at least, that how I think it would finish up. It's entirely possible I'm making some crucial error here, especially because this is all done without a board, and it's not like I never make mistakes even when I'm using a board and a comptuer and... well, you get it..
