I wonder what is the knowledge of shredder in the evaluation function that other programs do not have. Does shredder know to evaluate the last endgame hiarcs8-smirin correctly? My impression based on analysis with shredder5.32 is that it only after understanding that the pawn d6 is trapped by search it understands that black has better chances but I cannot be sure that the latest shredder is not better.
