Maybe Yamato refered to the situation of seki. I believe my approach can solve all the normal situations. Attached is a simple example that Black's best move is to pass (the result is B+0.5).

My approach in such condition works well. The reason is: If Black fills his own territory, or suicide one stone in White's territory, then all the playouts will claim White's win if White passes in UCT tree.

Zen also considers the difference of Japanese rules and Chinese rules
in
the playouts. However it is unstable when the pass is the only winning
move. I wonder if MFG can handle it correctly.
