Any bishop move allows Bg7 and what looks to me to be a dead draw. Obviously 1. BxB is out of the question. King moves are futile, and promoting on h8 to anything other than a knight is useless. The knight seems harmless enough after 1. h8(N) Bxg7 there is little future hope for the white pawns to grow up and be Queens. Since I ruled out everything, I'm obviously missing something, like the solution.
Originally posted by Caro KannWhy does black leave the a1-h8 diagonal in your variation after 1. ...Bg7? Is this forced? It seems to me that black, once on the diagonal, can temporize endlessly. The only white pawn capable of making a threat is the e-pawn, and as long as black maintains the diagonal, the pawn can't advance. If it goes to e5, black's bishop can capture it with impunity.
