Yes <snipped> > and if yes: which programs do NOT make this type of mistake? Gandalf does not do preprocessing and I believe that there are a lot of programs that do not do this kind of mistake. My experience with chessmaster6000,hiarcs7.32 and Junior also suggest that they are better than Fritz5 in avoiding preproccesing. I believe that Fritz5 does more preprocessing than most programs. I have not Fritz6a but I read that Fritz6 is clearly better in avoiding preprocessing and this is one of the reasons thast fritz6a is better. Uri
