Engines don’t seem to be that good at analyzing. In the Polgar - Kramnik game
at Wijk aan Zee game, just concluded, a 97 move draw, with Judith down by two
pawns (1-3) in an end game with bishops of opposite colors, Shredder 7 with
depth of 30/42 shows Kramnik with a -3.06 lead. The game is a draw, but Shredder
7 can’t figure it out.
Ending position: 8/8/3p1b2/3P4/7p/4k1pK/8/7B b - - 0 1
