Subject: CM9 mystery?

Author: Kurt Utzinger

Date: 14:14:41 09/14/02

Zugeordnete Felder 1.g4 - Cheron 0724
[D]8/8/K6p/6p1/8/8/k5PP/8 w - - 0 1

In this position the old TheKing 3.12d under Fritz7-GUI finds the winning move
1.g4 within 7s. CM9 with the same amount of hashtables (32 MB) needs 3m7s, but
CM9 with only 4 MB hashtables is the fastest with 3s. A real mystery for me, all
on P4 1800/512.
