I am surprised that the >alpha didn't have time to find this, or at least have time to fail low at >depth-14, which is strange. I see from the pgn file that the alpha used only 75 seconds for playing and if you add pondering time it is 75+38=113 seconds. I think that Crafty simply did not use enough time for this move. The time control was 120 minutes/60 moves. I suspect that Crafty uses more time in 120 minutes per game than in 120 minutes per 60 moves(at least this is the situation under chessbase interface) and it is not logical. Uri
