AlphaGo posted a second straight win against Lee Sedol 9P on Thursday in Seoul. "Yesterday I was surprised but today it's more than that — I am speechless," said Lee in the post-game press conference. "I admit that it was a very clear loss on my part. From the very beginning of the game I did not feel like there was a point that I was leading." DeepMind founder Demis Hassabis was "speechless" too. "I think it's testament to Lee Sedol's incredible skills," he said. "We're very pleased that AlphaGo played some quite surprising and beautiful moves, according to the commentators, which was amazing to see."

The complex, tense game ran nearly five hours and appeared to offer validation of AlphaGo's evaluative ability, the main roadblock to proficiency for previous go programs. Hassabis said that AlphaGo was confident in victory from the midway point of the game, even though the professional commentators couldn't tell which player was ahead.

Lee, the winner of 18 world championships, must now win all three remaining games to win the million-dollar prize.
