We've tried several things around that:

1) play the semeai first
- spot semeais (not that hard after all, from statistics on simulations)
- solve them with a dedicated solver
- play the moves which simplify the semeai before the rest of the
Monte-Carlo part

2) discard simulations
- spot semeais
- solve them with a dedicated solver
- discard simulations which propose a result which is not consistent with
the dedicated solver

3) add expertise (positive for semeais that should be played immediately,
negative for others)

Some of the experiments are here:

and there's nothing which works, even on very simple semeais :-) as many
people in this mailing list have tried similar things and failed as well I
start thinking that I'll die of
old age before someone solves this :-)    (and I congratulate in advance the
person who will
solve that :-) )

Best regards,
Olivier
