Game 3 - March 12, 2016

“It’s arguable that in the first two games Lee Sedol was playing differently than his true style, trying to find a weakness in the computer. Today Lee was definitely playing his own game, from his strong opening to the complicated moves in the final kō. AlphaGo was ready for everything, including the kō fights, and was able to take the win. I’d like to congratulate the people who actually made this accomplishment possible, because it’s a work of art.”

“Lee Sedol played well. As a professional player myself, I’d like to show my respect to his three consecutive games against AlphaGo, which played almost perfectly. Lee made a few diverse moves at the end of today’s game to understand more about AlphaGo. I look forward to remaining games as well.”

AlphaGo has just won its third straight game, claiming overall match victory against the best Go player of the last decade, Lee Sedol. Playing as white, AlphaGo won by resignation after 176 moves. Lee used up all of his time and two periods of byō-yomi overtime, while AlphaGo had 8:31 left on the clock.AlphaGo created a large territory on the board but Lee Sedol used a few innovative tactics to start a huge all-or-nothing kō fight and complicate the situation. In the resulting kō fight, AlphaGo prevailed.All five games will be played to determine the final match score. The next game, Game Four, will be on Sunday, March 13, and the final game, Game Five, will be on Tuesday, March 15.
