The option that I'd have researched is:

- spot semeai
- solve them with a dedicated solver
- if a move needs to be played to decide the semeai, favour that move
in playouts (i.e. play first with a certain chance).
- if a move is played in the semeai that requires a reply to keep
winning, favour that reply in playouts.

I don't say it would work any better. Just that it would have been
first on my list to try.
