Alexander Kure posted a position from a game he played: [d]8/p3b3/1k6/4p2p/K1Pp2pP/3P2P1/3N4/8 b - - 0 1 He played Bxh4 and gave the following winning line: 1...Bxh4 2. gxh4 g3 3. Nf3 g2 4. Kb4 a5 5. Kb3 Kc5 6. Ng1 e4 7. dxe4 a4 and the 3 black passers are too much for white to handle. however 1...Bxh4 2. gxh4 g3 3. c5 is an intersting try. Kure wrote: 3. c5 Kc6 4. Kb4 g2 5. Nf3 Kc7! and white is in a kind of zugzwang position, e.g. 6. Kc4 a5 7. Kb3 Kb7! is winning for black. but I doubt that. A possible continuation is 8.Nf3-g1 Kb7-c6 9.Kb3-c4 a5-a4 10.Kc4-b4 e5-e4 11.Kb4xa4 e4xd3 12.Ka4-b3 Kc6xc5 13.Kb3-b2 and draw... Vincent of course already proved it, that it is winning for black, but won't probably tell us, since we poor guys can only look at a programs output and have no understanding of chess :-( So I fear we have to prove it ourselve. What are xour opinions? Note: There are zugzwang motives, so don't simply look on the evaluation, but play the lines further to see what happens.
