Vas was right to be ashamed of Rybka's >>endgame, there are things to fix there still. >> Hi George, yes, overall evalution is superb (except for the endgame) and differs in many cases from engines not based on so much chess knowledge. I am starting to ask myself if only a strong chessplayer like Vasik could design such an engine adding his undoubtedly also good programming skills. Another observation: Rybka is aware of good pawn structures, but does not care to have bad ones like backward pawns when getting compensation. From the games I watched typical maneuvres are also creating good outposts for pieces. I saw several times like it neatly places the rooks on the sixth rank when they could not be exchanged, hampering the opponent considerably. With "very positional" default games are reminding GM play. But CEGT testers are also planning to test at least another setting. Probably "very tactical". Best Regards Heinz
