interesting that Shredder 9 has huge problems with this position. If you force
Be2 Shredder 9 realizes pretty soon that white wins. Fruit 2.0 has no problem
with this position and gets a winning score pretty soon (on Pentium M 1.6 GHz):
8/8/8/1k6/4p1B1/8/P2K1p2/8 w - -
Engine: Really Shredder 9? (128 MB)
