Subject: A quick endgame test...

Here's a position where postmodernist made a foolish mistake and got squashed by
crafty:

[D]3R4/5k2/1p1p4/1NbP2pp/2P3P1/P7/5rKP/8 w - -  am Kg3

PostModernist takes 13 seconds to latch onto Kh3 on my Athlon 1200, but it
didn't have enough time in this short game. How long does it take your engine to
see that Kh3 is better? Furthermore, after making the losing error, how long
does it take your program to find that Black will win:

[D]3R4/5k2/1p1p4/1NbP2pp/2P3P1/P5K1/5r1P/8 b - - 0 1 bm h4


The whole game is presented below (I believe PM went wrong around move 57, but
I'm not too bothered about that at the moment):
