I'd be surprised if programs see a win at normal game-type >time controls (other than 'postal' games). This position is a simple win for black. For example: 1... Kf5 2.Ba1 Bf1 3.Bb2 Be2 4.Ba1 h2 5.Kxh2 Kf4 5.Kg2 Bxf3 6.Kf2 Ke4 7.Ke1 Kd3 and black wins the white bishop and the game. White may defend in a different way, but without any hope. A human will win this position easyly. Crafty does very poor on this kind of positions. So it's output here is not very usefull. Look at H. Exner's pawn endgame test, pos12 8/6Bp/6p1/2k1p3/4PPP1/1pb4P/8/2K5 b - - bm b2; or on the famous position from Topalov-Shirov 8/8/4kpp1/3p1b2/p6P/2B5/6P1/6K1 b - - 0 47 Kind regards Bernhard
