At longer time controls crafty will find fxg5. >I am not quite following this. This game was played by you against another >program (not crafty)?

I then set up this position in WinBoard, fired up crafty in analysis mode and played the moves it seemed to like. I used analysis mode rather than normal play because I wanted to see the lines and eval it was thinking about. That display is better in analysis mode rather than normal play. -- GCP
