Passed pawns are a problem for EVERY program. Maybe CSTal evaluates them correctly but I don't know any other program which handles and evals them right. >3th position(from game 30 of the match): >8/1r2kpp1/b1p1p3/P1P1P1bp/3P4/2B3PP/P1N5/4R1K1 w - - 0 1 > >white has 2 pawns advantage and it is enough compensation for the positional >advantage of black. >I think that the game should be drawn but Hiarcs7 lost this game with white. > >I did not analyze the game to find the losing mistake. To me this position is not clear. There is much dynamics in it with the bishop pair and the weak pawn d4. >4th position(from game 32 of the match): >3r2k1/4bppp/p1n1pn2/8/Pp2N3/1B2B3/1PP2PPP/4R1K1 w - - 0 1 >again Hiarcs7 with white should not lose but it lost the game. Uri, Of course this SHOULD not be lost. Like many other positions. Like many other positions Hiarcs WON. An equal position is no forced draw. It has equal chances for both sides. But from time to time one side makes at least one bad move so that te opponent wins. This is nothing unusual. If it weren't so we would see almost no wins. What I want to say is that because of 2, 3, 4 or 5 examples out of a match don't show much. Ignore for a moment that I disagree with your idea that Hiarcs made bad positional moves (mistakes) or Fritz5 played better positional moves. What would change my mind if Hiarcs loses more games than these few because of such inappropriate endgame play. If H7 loses 4x because of this but wins 20x in other endgames while Fritz wins these 4 and loses the other 20, well, what would you say? And BTW you can interpret almost every loss as positional blunder at a certain point.
