All mcts programs have trouble with the positions near the end. The group in the center has miai for two eyes. Same for the group at the top. The upper left side group has one big eye shape. For all three groups the playouts sometimes kill them. The black stones are pretty solid, so the playouts let them survivie. SO even at the end, zen has 50% win rate, MFGO has 60%, and pache has 70% win rate for blasck.
The CS game doesnt have this problem.
