Hmm, I thought based on your paper that Erica uses a sort of a hybrid -
probabilistic simulation completely, but with all but 3x3 feature filled
in only around the last move anyway. So, one could say, Zen-like, but
with "3x3-based tenuki sampling" or whatever you want to call it. :-)
Has this changed recently?
