Fillboard also doesn't help Many Faces. Perhaps because I already have more randomness than mogo in the playouts.

CrazyStone certainly used to work like this when it was around the top. In mogo with the "fillboard" option, plenty of moves are possible (but not all). Even without fillboard, the number of possible moves is >1. The randomness introduced by "fillboard" (and Arpad is at the origin of this idea) made a very big improvement of mogo. The "portability" of this modification (which is incredibly efficient in mogo in spite of the fact that it takes less than 5 lines) is still an open problem to me. Incidentally, I guess CrazyStone is still around the top in 19x19 at least, unless the top has strongly moved recently :-) Olivier
