AlphaGo prevails over Ke Jie 9P in first round of 3-game match

Tuesday May 23, 2017

In an exciting game played out to the last dame, the latest version of AlphaGo defeated Ke Jie 9P by half a point on2017.05.23_AlphaGo China  Rd1 Tuesday in the first round of a 3-game match in Wuzhen, China, part of the Future of Go Summit. The Summit features several formats, including pair go, team go, and a 1:1 match with the world’s number one player Ke Jie.

“Ke Jie fought bravely and some wonderful moves were played,” said Deepmind’s Demis Hassabis. “Interesting game, but it didn’t seem like Ke Jie ever had a real chance,” tweeted SmartGo programmer Anders Kierulf, an assessment that seemed shared by commentator Michael Redmond 9P, whose analysis from fairly early in the game had AlphaGo leading. However, Ke Jie was clearly prepared with a strategy — his second move was on a 3-3 point — and the complex game kept go fans riveted to their screens around the world and, in the US, into the wee hours of Tuesday morning as the endgame played out, providing plenty of fodder for the English language commentary team, which, in addition to Redmond, included Hajin Lee 4P, Stephanie Yin 1p and Andrew Jackson 4d.

The Future of A.I. Forum will take place on Wednesday, the second AlphaGo-Ke Jie on Thursday, pair and team go on Friday, and the third AlphaGo-Ke Jie match on Saturday. (use this Time Zone Converter to determine local dates/times)
