The decisive victory by the AlphaGo program in what might be the world's most complicated board game provided further proof that computers can be developed to handle some difficult tasks better than humans.

"I thought I was close to winning," Ke told a press conference after his defeat. "I was too nervous so I made wrong moves. I guess that is a major weak point of human beings."

While praising the program as "the God of Go," Ke said, "I also feel a little regret because today I think played well."

Google, in cooperation with Chinese authorities, organized the Future of Go Summit in the town of Wuzhen, near Shanghai. Internet users outside China were able to see the first match between the program and the 19-year-old Ke on Tuesday, as well as the second game, through a live feed on Google-owned YouTube.

But despite huge interest, most Chinese people could not as Google services are blocked and authorities barred domestic broadcasters and online media from carrying live streams of the games.

According to Chinese journalists, they received directives from authorities that domestic organizations must avoid broadcasting the event live or mentioning Google's name in their reporting.
