AlphaGo defeats Go champion in first match

Google’s artificial intelligence program AlphaGo defeated Korean Go champion Lee Se-dol in their historic first showdown on Wednesday (9 March 2016).

In a landmark match held at the Four Seasons Hotel in Seoul, the Google AI beat Lee by resignation in 186 moves after a fierce tug of war for more than 3 1/2 hours, The Korea Herald reported. 

“I was really surprised. I didn’t think I could lose,” Lee said at a press conference after the match. 

“I didn’t think AlphaGo would play in such a perfect manner. I like to express my respect to the Google team for making such an amazing program.”

The two players have four more matches to play. The second match on Thursday, in particular, seems important for Lee, the highest ninth dan player with 18 international titles, to take revenge and lead the remaining matches. 

Unlike the relatively peaceful matches with Fan Hui, the first professional Go player to compete with AlphaGo, in October, the Wednesday match was a nip and tuck race.

Unlike expectations, Lee chose black stones to open the race. Under Chinese Go rules, a player playing with white stones receive advantages for playing later. 

After he put his first stone in the right top corner, it took 1 minute and 30 seconds for AlphaGo to make its first move in the left top corner. Its stones were placed by Google DeepMind Programmer and amateur sixth dan player Aja Huang. 

Lee, known for his aggressive and unconventional style of play, put stones in unexpected places at times and AlphaGo seemed confused about his moves. 

But despite some clumsy moves, the AI never seemed distracted and that frustrated Lee at the last moment.  

“AlphaGo’s skill has drastically improved even after its first victory against a human player months ago,” said a commentator during the match. 

Google has not revealed any information behind AlphaGo except the records of the previous five matches with Fan Hui. 

Go, more widely known as “baduk” in Korea, is a territory game that requires intuition and creativity, among others.
