[D] 6k1/6p1/6K1/7P/8/5B2/8/8 w - - 0 1 Zappa (incl. 1.1) has the old 'bad bishop in the corner' trick that humans have used to embarrass computers for years. However, this position has a twist: White can play Be4 Kh8 Kf7 g5 (only move) hxg6. This gets White's pawn off the h-file. Of course, it also stalemates Black, but you can't have everything. Zappa doesn't detect stalemate in eval(), so its strategy is always "shuffle N-5 moves, then play Be4 Kh8 Kf7 g5 hxg6 and get the pawn of the square, and Black has no move to find he's stalemated". Crafty detects stalemate in the evaluation, so it gets this one. kburcham++ anthony
