For what it's worth, I did have MCP8 finish the game using standard tournament
time controls (3min./move), and Black did win! Your are correct about the
position being very interesting because MCP8 kept formulating, then rejecting,
plan after plan. Anyhow, here it is:
M-Chess Pro 8.0, P200-S, 96MEG
3 min./move, learning enabled
Completion of the game between Chessmaster 6000 and WCrafty 16.3:
