Google's AI Just Won its Second Match Against Go World Champion Lee Sedol

By Jamie Condliffe on at

In the second of a series of matches, Google’s AI has again beaten the world champion of Go, Lee Sedol. The best-of-five tournament now requires the AI to win just once more to be crowned champion.

Despite the first game, played yesterday, being described as “close” by Google, the AI is clearly giving the current world champion a run for his money. Quite literally: The overall winner of the five-game series will walk away with $1 million.

The AI, called AlphaGo, had already beat the three-time European Go champion Fan Hui over the course of five matches, but Sedol was largely considered to be a much harder challenge, having dominated the world of Go for much of his professional career.

But the chances of a victory for Sedol are slipping from his grasp. Three more games remain to be played, on the 12th, 13th and 15th of March. Sedol will have to win all of them to beat AlphaGo.
