Dirk,

I believe we already analyzed this positions with many different programs
a while back. If I remember correctly, Roland Pfister (author of "Patzer")
said that "Patzer" solved it very quickly but maybe for the wrong reason ...

Anyway, "DarkThought" spots the trouble with Bxa8 in iteration #12
(fail-low with large negative score) after roughly a minute on a 600MHz
Alpha-21164a. It locks onto g4 in the same iteration after another 30 sec,
i.e., after 1:30 min overall.
