I use Many Faces' knowledge in the search, but not the playouts. I made them as light and fast as I could. I don't have a way any more to just do playouts without the uct search. In your position after a few thousand playouts, it gets over 95% win for white and 5% win for black (depending on who I make move first).
If I limit the uct search to 1 ply, it thinks white wins 49.5% and black 49% (of the best move for each, always D9) I guess this confirms your assertion (and Don's as well) that light playouts without UCT search can't play well. With UCT search, it seems that light playouts are quite effective.
