Our solution was the following. We have two possible structures:
1) a big set of SGF games;
2) an opening book in which one line contains p,w,l where
* p is a situation
* w is the number of wins
* l is the number of losses
We can convert 1) to 2) easily.
The advantages are:
1) is quite comfortable for interactions with humans or will self-play
games;
2) is much faster to read and to apply for choosing a move with various
formulas (it's quite analog to a MCTS tree).
In particular, self-play for small boards is efficient for building good
opening books - well, I think it's better if you can have human experts, but
if you spend sufficiently many computational power on it you can build a
good opening book by self-play (the algorithm is by the way quite related to
MCTS).
Best regards, hope it helps,
Olivier
