The semeai analysis partially uses the same move generation as the owl
analysis but it also tries some other moves (typically liberties of
the opponent) and sometimes changes the move ordering. Node limits can
also cause a move found by owl never to be tested by semeai.

It's probably a reasonable idea but it might have issues with e.g.
caching. Feel free to try to implement it.
