I'm posting the whole game of an engine-engine match I played on my PC. White
was Hiarcs 7.32, Black was Chess Tiger 14.0, both were using 128 MB Ram. The
time conrol was 40'/40+40'/40+40'
The strange move is move 121. The position looks to me like a drawn game. Hiarcs
thought for 25 seconds to a search depth 13, evaluated Ka6 as 0.0, made his
move, and oops! -- he'd overlooked a mate in 1.
I've tried duplicating this error in vain. In analysis mode Hiarcs sees the
Mate. Has anyone else noticed similar things happening with Hiarcs?
