Yes, it eventually finds the right move, but that's not the issue; after four minutes it still comes up with only -0.45. Why does it gives a more realistic score (less than 2 pawns) if you force one move and wait for a small fraction of a second (a few plies)? I've only tried this position with Ruffian 1.0.5, and it gives less than -2.00 from ply 1. Something's not right here, if you ask me. Jaime
