Subject: Why does Fritz (unlike Crafty) NOT understand the draw.

Hi to all,

Yesterday eve I held a match between Fritz 7 and Crafty 19.10. It came to a
(completely drawn endgame) with Bishops of opposite colors, and 4 pawns each.
Both also had 1 doubled pawn.

If any of the two Kings abandonned his pawns, then at least one of them would be
grabbed. The pawns were all blocking each other. (I deleted the game
unfortunately). None of the two programs had a real plan, but Fritz did not see
the equality of the position.

Crafty's evaluation changed from +0.15 (advantage to Fritz) to 0.00 in a few
moves. Fritz however continued to believe that it was better with +0.50 (for no
particular reason as far as I could see) and wanted to continue the play, even
though he had no plan at all. He just wanted to walk around in circles with his
King, and move his Bishop around the board aimlessly.

Why was Crafty able to see that there was no way to win, whereas Fritz did not
seem to have a clue?

Regards,

Geert
