Google's Go-playing AI still undefeated with victory over world number one

Google's Go-playing AI has won its second game against the world's best player of the ancient Asian board game, Chinese 19-year-old Ke Jie, taking the three-game match in the process. In the post-game press conference, Hassabis, who was a child chess prodigy, said: "For the first 100 moves, it was the closest we've ever seen anyone play against the Master version of AlphaGo." "Ke Jie pushed AlphaGo right to the limit," Hassabis added on Twitter. After narrowly losing the first match, a visibly shaken Ke had described AlphaGo's latest version as "godlike". This time, he was more relaxed: "Today's game was different from the first. AlphaGo made some moves which were opposite from my vision of how to maximise the possibility of winning. I also thought I was very close to winning the game in the middle but maybe that's not what AlphaGo was thinking. I'm a little bit sad, it's a bit of a regret because I think I played pretty well."
