According to Chessmaster 6000, Crafty made two successive incorrect plays that
(would have) lost the game:
40... Nc8 should have been Nd5, with a score of -1.46
41... Rb3 should have been Rb1+, with a score of -0.53
After these two moves, White has more than made up for all of the lost material
(3 pawns!), and has complete control of the situation.
Of course, I only let CM think for about 20 seconds per move. If I had let it go
longer, the data would certainly be more accurate and/or useful.
