Alphago beats the number one human Go player in first of three matches

Deeplearning AI Alphago has defeated Ke Jie, the world's number one human Go player, in the first game of a three-part match.

Despite defeat, Ke's strategy suggested that the 19-year-old Chinese prodigy has actually learned from AlphaGo's often unorthodox approach.

AlphaGo won by just half a point, the closest margin possible, but that's characteristic of its playing style. The AI doesn't appear to care about the margin of victory, instead choosing moves that it has determined are the most likely to lead to a win. The result was technically close, but AlphaGo looked like winning from a relatively early stage in the game.

#AlphaGo wins game 1! Ke Jie fought bravely and some wonderful moves were played.

Interesting that Ke Jie has decided to play an very early 3-3 point as he knows #AlphaGo likes to play there.
