The awful frustration of a teenage Go champion playing Google's AlphaGo

This is the face of desperation. Ke Jie, the world's best human Go player, lost two games against a new version of Google's AlphaGo on May 25. This means AlphaGo has already secured victory in the three-part match. The third game will take place Saturday (May 27), during the ongoing "Future of Go" summit in Wuzhen, China, where the game was born. The 19-year old Chinese player looked exasperated during his second match against Google's artificial intelligence player.
