Re: Buggy pgn output from a CEGT & CCRL gui

<snipped> Some gui(s) used by both CCRL and CEGT produces pgns that violate an important pgn principle. [/code] I do not understand what is the importance of the principle that you give. I see no big problem if irrelevant information is posted. If the reason is size of the pgn then I think that it i...

Re: Material imbalance evaluation

One should also realize that uMax cannot recognize the Bishop pair, so the value for the Bishop includes also the averaged bonus for the fact that it might be one of a pair. This should be taken into account when comparing with the piece values in other programs, that give a separate bonus for poss...

Re: Material imbalance evaluation

I just did an interesting experiment in uMax concerning piece values. The standard version always used the 'classical' values 1,3,3,5,9. As uMax fails to correct for piece-square points of the captured piece, this makes trades of B vs N, B or N vs 3P, 2B vs R+P completely equal, and therefore often...

Re: Shredder 10.1 now released

<snipped> Shredder is very, very good. He has made a big leap in performance. And I even think he is on a par with Rybka 2.3 or even stronger in some positions. I do not claim something bad about shredder but being stronger than rybka2.3 in some positions is an easy target because rybka2.3 has bugs...

Perhaps he means that Black scores 80%?
White scored 80% in the games that Dann posted.
