Move-response information fits perfectly into the mc flow. But it doesn't fully reflect the logic of a semeai with libs, shared libs, lib extensions, approach moves, and eyes of various sizes. So it can only be of limited value. Incremental updating of information sounds like a idea good though. That might even eliminate or atleast reduce the need for top-level analysis. In any case, just improving the playouts won't be good enough. Semeai information must be available in the tree to reduce useless permutations.

It is expensive to solve semeai during every playout, but what if semeai solutions were done once per game move (or even less frequently), and the information obtained were then amortized over many playouts?

The top-level analysis would solve the semeai, and create a self-updating set of move-response triggers. The tricky bit is that the indicated behavior must correctly adapt to all possible moves during a complete playout, in a manner which does not interfere with other simultaneous playouts.
