Subject: Difficult endgame position

Author: Enrique Irazoqui

Date: 03:06:40 06/07/00

Fritz 6b takes 18' 26'' on a P600E with 184MB hash to pick 1.h6, but it doesn't
see the winning line yet after one hour of being stuck at ply 20/43, eval -0.12.
How long does it take for other programs to play h6 with a winning evaluation?
