I did not try something like plays globally until the xxx move then locally. Perhaps it should help. Hmm its probably rather difficult to find the balance, local answer are very often needed. Good stuff would be : when no local answer is needed, then take initiative and play one big/global

Hello, Also on 19x19 mogos plays also some very slow moves in the beginning of 7 handicap game. I guess that using (average_score / standard_deviation_of_score) instead of (winning_probability) should solve both problems at the same time. yes you're right, MoGo is very weak in the opening

But is there other conditions? Could I pass really early and trick Mango into passing if I wanted to? A very simple approach works like this: 1. When winning very convincingly in Chinese, play quickly. 2. When losing convincingly, resign. Your opponent, when losing has 2 options.
