What you're saying is that Fritz's evaluator has large systematic errors. But as long as it's OK at ranking positions in the search tree, it can still play good moves. In the absence of an immediate draw, only the relative evaluations of positions matter, not the absolute evaluations, and systematic errors don't hurt. Jay
