AlphaGo wins third consecutive victory

By Park Si-soo, Lee Han-soo

Google-developed artificial intelligence AlphaGo defeated the world go champion Lee Se-dol on Saturday, extending its winning streak to three games in the historic five-game tournament. Lee threw in the towel after 176 moves.

AlphaGo's victory once again stunned and disappointed many people who had hoped the South Korean go champ representing humankind would fight back and redeem his tarnished reputation in the third round.

The match made it clear what ― not who ― will win the $1 million prize money. And there is one last question left unanswered: Will Lee be able to defeat AlphaGo at least once?

Nothing is certain, at least for now. But given that AlphaGo completely crushed Lee in the first three games, chances for Lee to win any of the two remaining games is increasingly slim.

"We are a bit stunned and astonished by how Lee countered AlphaGo's movement in the beginning," said Demis Hassabis, founder of DeepMind, a Google affiliate that developed AlphaGo, during a media briefing after the game. "Lee Se-dol was able to counter the computer that could process thousands of moves per second during all three rounds with only his brain."

Lee looked disappointed at his three consecutive losses.

"I don't know what to say and I would like to say sorry, because I couldn't show you my better results," he said. "I think even if I go back I probably cannot defeat AlphaGo and I think the competition was already settled in the second match."

He said, "Humans have psychological issues while AlphaGo does not. Nevertheless, I think I will be able to discover AlphaGo's weak points in the fourth and fifth match.

The fourth match between Lee and AlphaGo will take place at 1:00 p.m. Sunday (KST).
