I think Zen's play starts to look really impressive. It was hard to
detect the usual relative weaknesses of MCTS bots. Maybe Ha Yongil did
not put open enough simultaneous battlefields.
But the ruthless play in top left, when tsumego is not the current bots'
specialty, or its way of taking profit while harassing the invading
group, are good testimonies of the bots' evolution on the two latter
years I think.
