I agree that it does not understand this position but the same is for CStal +2.59 is too optimistic and I think that the advantage of black is not so big and 0.4 pawn is more realistic <snipped> >What CSTal2.5 evaluates is not real. it evaluates the CHANCES of the position to >use in further moves. I think the chances to win with 1 pawn material advantage with no compensation in the middle game are better. <snipped> > Cstal2.5 >has a different idea. >it likes Kb8. >In reaction fritz evaluates the position now 0.03. Still a draw-score. >Some exchanges follow. I believe that Fritz did not choose the right exchanges. I think that it is better to play 28.Qxc4 Qf3 29.Qa4 and white is not worse because the black king has also probvlems. <snipped> >it is the 32nd move. fritz evaluates 0.06. arround draw. CSTal 2.5 says +2.15. again I think the +2.15 is too optimistic I believe that chess system tal is not going to win this position against better programs. I believe that 59.Rd2 could save the game for Fritz. Fritz simply forgot to move the king to the game. Uri
