My score went from +4 to about .3 at depth=13, the move played was not best, but when crafty failed high on Qf4 (the second move in the move list) it simply could not get a score back in time. If you start crafty from scratch, it fails low on Rxd7, and changed to Bb2 which is also +4. But in the game, it had already searched a lot before it got here and the move ordering was different due to hashing. Rxd7 does seem to be bad however. > >Nimzo vs. Crafty >[D]8/8/1pp5/3k1p1p/Pp1p1P2/1P4PP/2P2K2/8 w - - > >Nimzo played Kf3 here and ended up losing. Ke2 might draw here.
