The two moves that mattered
Move 37 — AlphaGo, Game 2
A shoulder hit on the fifth line that broke centuries of Go wisdom. Beautiful, and alien.
DeepMind’s estimate: a human plays this ≈ 1 in 10,000
Move 78 — Lee Sedol, Game 4
The “hand of God.” A wedge in the center that found AlphaGo’s blind spot and won the only human game.
More than 200,000,000 viewers worldwide watched the match.
