Well, Crafty is Dr. Hyatt's program, but starting from:
r1r2k2/1p4pQ/1n1bp2p/p2n1p2/P2P2Nq/1B5P/1P3PP1/R1BR2K1 w - -
Crafty prefers Ne3 right away, and sticks to Ne3, until disaster is seen at ply
13. At ply 13, Crafty chooses Bxd5 momentarily, then switches to Re1. Crafty
never considers Nxh6. Ignore the times. I used "start/low crafty2.exe", which
gives Crafty very little horsepower.
