I understood from the discussion that they discovered bugs including bugs in the evaluation in games 1 and 2 of the match against kasparov and fixed them for the rest of the match. Maybe I undertsood wrong and I did not read Hsu's book. I do not want to support Hsu after he left computer chess. I think to buy it only if Hsu returns to computer chess. > >Should I say Fritz has big evaluation 'bugs' because it completely misevaluates >many positions? Should that be cause to say Fritz has worse evaluation than >some other program(s)? No It is different. Fritz may evaluate wrong something because of lack of knowledge but I believe that the demage from wrong knowledge is often bigger than the demage from lack of knowledge. Uri
