In fact in game 2, white 172 was described [1] as the losing move, because it would have started a ko. (I suspect the game was already lost, and that lesser MCTS programs would have managed correct play from there, but it would still have been useful to see.) (By the way, in game 2, black 43 and 45 were described as "a little heavy". It did seem (to my weak eyes) to turn out poorly. I'm curious if this was a real mistake by AlphaGo, or if it was already happy it was leading, and this was the one it felt led to the safest win? I really hope the AlphaGo team will publish what it thought its winrate was after each move.)
