AlphaGo vs AlphaGo Game 5: An AI-like opening, then one fight at a time and a beautiful endgame

Saturday September 2, 2017

“In the opening this game looks very AI-like to me, in that I think the order of moves is not consistent,” says Michael Redmond 9p in his game 2017.09.02_alphago-game5commentary on AlphaGo-AlphaGo Game 5. “In the middle game Black controls the center of the board. Our reading skills are tested as Black invades White’s moyo, and then White lives with three weak groups inside Black’s sphere of influence. Unlike in other games we’ve seen so far in this series, the middle game fights are one at a time instead of all over the place, like in Game 2, for example. It’s more organized, you might say, so in that way, it’s easier for me to explain what’s going on. The game winds up with a very nice endgame, in fact I think it’s a beautiful endgame.”

As usual, the commentary in the sgf file here includes variations not covered in the video commentary, and for the first time, the sgf commentary now includes additional comments transcribed from the video. Both include the news that Redmond and Garlock are now working on an e-book about the AlphaGo-AlphaGo games. Redmond and Garlock discuss their plans for more AlphaGo-AlphaGo commentaries in this brief video.
