AlphaGo-AlphaGo Game 4: Reminders of Go Seigen, escalating trades and semeais, and a final ko

Friday August 4, 2017

“With this game I get to talk about some moves in AlphaGo’s opening that remind me of the great player Go Seigen,” says Michael Redmond 9p 2017.08.04_alphago-alphago-game4in his game commentary on AlphaGo-AlphaGo Game 4. “The territory is very close throughout the game, while fighting in the center gradually escalates with trades and semeais to be calculated and discarded, and even during a final ko to kill a huge Black group, the correct variations leads to a half point difference.”

AlphaGo-AlphaGo Game 3: Three 3-3 invasions, a big moyo and a fight that fills the center of the board

Thursday August 3, 2017

This exciting game features an astonishing three invasions at the 3-3 point, prompting Michael Redmond 9p to note that “This version of AlphaGo 2017.08.03_AlphaGo vs. Alphago Game 3will invade here at any time when there is no urgent fighting going on. AlphaGo played an early invasion at the 3-3 in just two of the 60 Master series games, but that was shocking, as it defied the common knowledge of pros that such an early invasion should be bad. In this 50-game series AlphaGo played an early 3-3 invasion about 40 times.”

“Black plays a big moyo game, and then chases an eyeless White group into Black’s moyo, to start a fight that fills the center of the board,” adds Redmond.

Wednesday August 2, 2017

“In this game AlphaGo shows great flexibility in the early stages, and also its ability to calculate extremely complicated fights later in the game,” 2017.08.02_AlphaGo vs. Alphago2says Michael Redmond 9P in his commentary on Game 2 in the AlphaGo-AlphaGo self-played series. Click here for his video commentary, hosted by the AGA E-Journal’s Chris Garlock, and follow along with the sgf below, which includes the extra variations Redmond refers to in the video. “Against Black’s sanrensei, White plays two unusual moves at 10 and 16 to create a unique opening,” says Redmond. “As the fighting starts, White makes a surprising sacrifice, abandoning a group to take the offensive in the center.

Redmond’s AlphaGo-AlphaGo commentaries launched

Tuesday August 1, 2017

In the first in a new series of AlphaGo video commentaries, Michael Redmond 9p, hosted by the AGA E-Journal’s Chris Garlock, reviews Game 1 of the amazing AlphaGo vs. AlphaGo selfplay games. The 50-game series was published by Deepmind after AlphaGo’s victory over 2017.08.01_AlphaGo vs. Alphago with Michael Redmond 9p Game 1world champion Ke Jie 9p in May 2017. Games 2-4 will be released this week, leading up to this year’s U.S. Go Congress in San Diego, which starts on Saturday.

“In the Master series earlier this year, AlphaGo first showed its big shimaris, and often played to dominate the center of the board in the early opening, using its famous shoulder hits to do so,” says Redmond. The Master version “had an early advantage in almost all of the games,” Redmond says, “and I was impressed with its ability to simplify complicated middle game positions and bring the game to an early outcome. Less convincing was the way Master handled complicated joseki. It also had a disturbing habit of losing several points in the endgame to win by the smallest possible margin.”

“With this new self-played series,” says Redmond, “I wanted to see how these traits had survived AlphaGo’s evolution; five months is a long period of time for a self-teaching AI. The exciting news is that Alphago has changed dramatically.” Click here, to find out how in the video commentary and see below for Redmond’s extensively commented sgf file. The videos are produced by Michael Wanek and Andrew Jackson; sgf editing support by Myron Souris.

Sunday May 14, 2017

“In this game from 1670 Honinbo Dosaku plays White against Yasui Chitetsu, his major rival in the Yasui house,” says Michael Redmond 9p in this video commentary, hosted by Chris Garlock of the AGA E-Journal. “In this game I will comment on Dosaku’s brilliant sabaki in the early middlegame, in a position that I find to resemble the way Master invaded the Chinese opening in games 22 and 48.”

Episode 2: Honinbo Dosaku 9P v. Kikukawa is the latest in the new series of video commentaries with Michael Redmond 9P and Chris Garlock, Managing Editor of the American Go E-Journal.

In today’s commentary, Redmond and Garlock take a look at a 347-year-old game that not only features the move that 2017.03.08_Redmond's Reviews Episode 2Kobayashi Koichi 9P said changed his life, but includes moves that Master — the latest version of AlphaGo — played in its recent 60-win sweep of top professionals. Go history in the making!

Honinbo Dosaku (1645~1702) was by far the strongest player of his time, and is still considered to be one of the strongest players in go history. He made important contributions to go strategy for the opening, laying the foundations for the following golden period of progress for go.
