AlphaGo beats Lee Sedol in third consecutive Go game

Google's AlphaGo computer program has won a third and decisive encounter with a top-ranked player of the Chinese board game Go in a victory marking significant developments in artificial intelligence. Lee Sedol, who is the world's second best player of the strategy game, lost three games in a row in Seoul this week, with the latest AlphaGo victory on Saturday handing Google the best-of-five match. "I've never played a game where I felt this amount of pressure, and I wasn't able to overcome this pressure," Lee said at a post-game press conference. Go has simple rules, but is highly intuitive and complex in practice. Mastering it has been an exceptionally difficult task for even the world's best IT designers.
