[D] 8/7p/8/1pP1kp2/1P1n1P2/P3pP2/4B2P/5K2 b - - 0 1 bm Kd5
Kd5 draws, Kxf4 loses. I really like this one - proving the loss after Kxf4 is
not trivial but to find Kd5 is still very doable for a human amateur player - a
positional decision.
Fritz is very impressive here and finds it in under a minute on a PIII1200
notebook.
