You might try the turn-based servers, where 1 move/day is considered a 
fast game. The downside is that each game can take months. Also, I don't 
think there are automated interfaces.

I was about to say, "First 5 moves? What can go wrong?" Then I looked at 
the games. 

I think you mentioned that the moves are selected based on a weighted 
combination of Gnugo's move valuations and your minimax search based score 
estimates. Would it help to adjust those weights during the course of the 
game? In the extreme case, you let Gnugo play the first five or ten moves 
by itself, then take over once the fighting starts.

No problem. Including that result, the win rate becomes 79% (58%-93%),
score remains W+31 (W+12 - W+50), and p = 0.0033 on the binomial
distribution. Doesn't change much.
