IE you use it to relocate the bishop to a better square. It is bad if you play it just because you can (in this case because taking it traps and loses your queen). For Fritz, it was apparently the latter as it later went back to where it was before the move was played... And that does look stupid... > no if you play it thinking in f7-f5-f4 because this bishop (on b8 later) >will help in that case, specially for that Xg3 square (after f4e3), the problem >is that Fritz didn't realize the plan and then place te bishop back on e7.

IE after Nf3 Fritz took over four minutes to play Nf6. That was odd. It then apparently went back into book after c4 by Kasparov and the game was off to the races, except that Fritz tried the a6 rather than Nbd7 move from the game-1 setup. However a critical part of a computer chess program is the ability to avoid releasing tension by either playing a pawn capture in the center, or advancing a pawn so that it becomes blocked. DF seemed to have problems in this area. Since it does, it would be better to avoid playing such openings, which is one way to "hide" the basic problem to an extent... >and i hate that because it make no sense, having the chance of match your >program against such a oponent is a great oportunity because Kasparov (also >Kramnik, Karpov and Anand) can show you the weakness of your program even in the >case He lost the game, and everybody can learn from that.
