On CGOS 9x9 games i _feel_ that increasing the level gives really more
strengh (twinbot at level 12 is ranked 30 ELO lower than at level 14, =4% 
of win probability).
Maybe this is not due to semeai_nodes, but on a 9x9 it seems probable that
this is important.

I wonder if playing with more semeai nodes would not gives some other
testcases where we see more differences than the actual regression suite.
