There's still one problem...
The description of HB04 says "Old version 0.4 of HouseBot. Uses MC/UCB, no
UCT".  In reality, it does not do MC (or UCB) at all.  It votes on moves
based on simple heuristics such as descending to protect a group's skirt,
placing stones in atari, forming benson unconditional life, etc...  It's
1-ply logic like UCB, but has absolutely no MC element.  That's why it plays
blazingly fast...  Games of HB04 vs. IdiotBot have been known to finish in
seconds.
