True, and if Fritz really intended to play for the draw then it would have been okay. The problem is fritz didn't "understand" that it was going into a solid draw, its evaluation is simply broken. Maybe the result would have been the same regardless for this game, but obviously you should not expect to see a program as strong as fritz evaluate so poorly. Bad evaluation will cost you points in the long run, for sure. -S. >Regards, > Terry
