Top Go player ponders AlphaGo matchup

The world's top weiqi (or Go) player, Ke Jie, believes he has got what it takes to beat the artificial intelligence program AlphaGo, which has just thrashed South Korean grandmaster Lee See-dol, but Ke admits his chances of winning are shrinking as AlphaGo "learns" at a stunning pace.

Developed by Google's London-based AI subsidiary DeepMind, AlphaGo ended its historic tournament against Lee on Tuesday. It clinched the competition between man and machine by winning the final match of the ancient Chinese board game and taking the seven-day series 4-1.

Ke, the youngest player to win three world titles, had claimed "AlphaGo can't beat me" before the much-hyped contest. After the dust had settled, he was still relatively confident.
