Crafty has specific eval code that says if it is down a piece, even with three pawns for it, it isn't going to be happy unless all the pieces are gone except for that one extra piece for the opponent. In every game I have ever played with a computer, being down a piece with a couple of rooks bishops and queens on the board has resulted in the side that is down a piece losing the game. I've tried to stop this. Perhaps here Qh5 is a good move, but my eval dropped sharply after that. I thought that Rebel would win this after it had such a wall of pawns left on the kingside, but it never seemed to try to get them moving, and a wall of pawns on the 2nd/3rd ranks is not nearly so impressive as that same wall of pawns on the 5th-6th... Interesting decision by Anand to start that Bd6 sequence.
