Crafty is one of the engines that has quite a hard time with this position as is Ruffian (that has even more problems). So I think it is about knowledge, or maybe about tuning?! Which one is the rule, which one the exception? Position 1 or 2? For non-master humans after the queen trade both positions look won for white at first sight I think. Crafty was playing the white pieces in this game and lost, I don't have the PGN though.
