I found a draft of what I believe was one of the computer-go
postings. I'll summarize again for anyone who missed it (and I'm not
sure I posted it.) :
I did do a 7x7 test against gnugo. I used a komi of 8.5 which I
believe is a win for black with perfect play. I base this on the
fact that when I used komi 9.5 everything reversed dramatically in
white's favor.
Boardsize: 7x7
Komi: 8.5
Opponent: gg-3.7.9
K-nodes Score when Black Score when White Combined score

Lazarus never loses as black when doing at least 32k play-outs.
Even with white, Lazarus manages to win most of the games at the
highest level - which shows enormous scalability - being able to win in
a lost position.
At the lowest levels Lazarus rarely wins with either color.
Not a lot of games but enough to show that there is not much point
continuing with 7x7.
