AlphaGo loses to Lee Sedol in Game 4

Google DeepMind Challenge Match
Seoul
13 March 2016

AlphaGo created a big central area, which Lee Sedol cleverly found a way to take apart to make the game close. AlphaGo played some strange moves when it thought it was behind, seemingly to test Lee. However these lost the machine some points and, despite being in overtime, Lee played very accurately and eventually at about 08:45 GMT AlphaGo resigned. Human and South Korean pride have thus risen!


Some more detailed commentary and pictures will be available on the GoGameGuru website.

Live streaming of the event will continue again for the final match in the 5-game series, on Tuesday at 4am GMT.
