The nature of the search is to return the line with the highest score. Probably the most natural approach to accomplish what you want is to award a bonus for simplification, making the move leading to the simpler position worth more than one that doesn't. IIRC, Crafty does do something along those lines (or maybe I'm thinking of "avoiding bad trades"). -- James
