AlphaGo, the Go-playing AI computer program developed by Google's DeepMind, outsmarted the combined power of five of the world's best Go players in a team Go game on Friday afternoon.

The five Chinese nine-dan professional Go players - Chen Yaoye, Zhou Ruiyang, Mi Yuting, Shi Yue and Tang Weixing - consulted each other on every move. Zhou, whose nickname is AlphaYang due to his deep understanding of the AI, was chosen as the team leader and positioned the stones on the board during regulation time. Tang put down the stones in overtime, almost working on his own, as his teammates appeared ready to face defeat.

Both sides were allotted two and a half hours and three 60-second timeouts. 

It seems that the five Go professionals were sometimes disagreeing with each other over the positioning of the stones throughout the game. As a result, they might not have taken full advantage of their combined strengths.

The match, as part of the Future of Go Summit in Wuzhen, East China's Zhejiang Province, has further cemented AlphaGo's position as the unbeatable master in the ancient Chinese board game.

At a pair Go game on Friday morning, AlphaGo and eight-time world champion Gu Li was defeated by the AI computer program and Lian Xiao, one of the top Chinese Go players. 

The AI also triumphed over Chinese Go master Ke Jie in two one-on-one games on Tuesday and Thursday, securing its victory over the 19-year-old reigning world champion in a three-game match. Ke will go up against AlphaGo in the final game on Saturday, the very last chance for a human player to beat the AI at the summit.
