AlphaGo Zero-AlphaGo Master: Two openings, less variety

Saturday November 11, 2017

“In the set of 20 games between AG Zero and AG Master, there are pretty much just two openings — i.e. identical moves for about the first 202017.11.11_ag-ag-zero-opening moves — one with Zero as Black and one with Master as Black,” says Michael Redmond 9p in this first commentary on the recently released AG Zero games. “This provides an opportunity to examine how Zero differs from Master, as well as how Master differs from earlier versions. ”

“When AGMaster plays against AGZero, it does not show the variety that it had before,” says Redmond. “As AG does not change within a version, I find it hard to accept that it apparently does not have the option to play moves that it played before in identical board positions. In the ‘Master series’, 60 games played against top pros in Dec 2016 to Jan 2017, Master could play the 3-4 point as it’s first move in about 1/4 of the games when it had Black. Incidentally, AGKeJie also could play the 3-4 point in some of it’s games. The fact that Master repeats the same opening every time in these games against AGZero bothers me and makes me question, is this truly the same version of AGMaster that played the Master series, and if so, what caused it to play the same opening every time in this series, when it was allowed to have variety in previous games with identical board positions? The difference in calculated winning percentage between A and B should be extremely small and I would expect it to have little or no effect on the ultimate win-loss record. This set of games would be much more valuable if Master had been allowed to vary in it’s choices for moves.”

Saturday November 11, 2017

Seong-Jin Kim 8d won the EGCC 25th Anniversary Tournament, held October 21-22 at the European Go Cultural Centre (EGCC) in2017.11.11_Seong-jin Kim 8d Simul Amstelveen, the Netherlands. The tournament was the centerpiece of the Center’s 25th anniversary celebrations, which included a series of events held October 20-22, from a European Go Teachers’ Day to simuls and an evening reception.

The festivities began on Friday morning, October 20, with a full day of seminars, discussion, presentations and brainstorming by eighteen go teachers from seven different countries. Rob van Zeijst and Kalli Balduin organized the session, which featured topics like the professionalization of Western go education, the mindset of the teacher and his students, the do’s and don’ts of go teaching, obstacles for go teachers and how to overcome them, and the everlasting question “how to best promote our 2017.11.11_Cleaning EGCCs Go Equipmentsport?”

A reception Friday night was highlighted by distinguished guests, including Hiroshi Yamashiro, vice-president of the Nihon Ki-in, Setsuko Kawahara, minister of the Embassy of Japan in the Netherlands, Maaike van Veeningen, alderman of the city of Amstelveen, Kenji Saito, chairman of the Japanese Chamber of Commerce (JCC) in the Netherlands, Martin Stiassny, president of the European Go Federation and Han Ellenbroek, president of the Dutch Go Association.

The EGCC Anniversary Go Tournament ran Saturday and Sunday, October 21-22, and was preceded by the work of three fanatics who cleaned all the EGCC’s go equipment, a long overdue task. Michał Łukasiewicz, Justyna Klęczar and Kim Ouweleen took several days to clean the Center’s 54 kaya and katsura go boards, as well as thousands of slate and shell go stones (left) and their bowls. On Saturday evening, after an Indonesian style dinner, participants had their choice of several fun side events, including simuls with Artem Kachanovskyi 1p, Cătălin Țăranu 5p, Seong-jin Kim 8d (top right) and Stanisław Frejlak 6d.

The Power Report (2 of 2): Rin Kaiho receives decoration in autumn honors; Ichiriki to challenge for Kisei

Saturday November 11, 2017

by John Power, Japan Correspondent for the E-Journal2017.11.10_Rin Kaiho

Rin Kaiho receives decoration in autumn honors:
Rin Kaiho (Lin Haifeng) 9P has been awarded a decoration by the Japanese government in the autumn honors. Rin (right) was one of the top players in the second half of the 20th century. He has scored 1400 wins as a professional, behind only Cho Chikun, and has won 35 titles, including the Meijin eight times, the Honinbo and Tengen five times each (he is Honorary Tengen), and the Oza, Judan, and Gosei once each. He is a disciple of Go Seigen, who received the same decoration, and has many Taiwanese disciples (though born in Shanghai in 1942, he is a citizen of Taiwan), including Cho U. The success for which Rin is best remembered is defeating Sakata Eio, 2017.11.10_Ichiriki L Yamashita Rconsidered almost invincible at the time, and becoming Meijin at the age of 23, then a youth record. Twenty-six Nihon Ki-in players have received a total of 37 decorations.

Ichiriki to challenge for Kisei: The first game of the play-off to decide the challenger for the 42nd Kisei title was held at the Tokyo headquarters of the Nihon Ki-in on November 9. Taking white, Ichiriki Ryo (left), the winner of the S League, defeated Yamashita Keigo 9P (right), second in the same league, by resignation after 216 moves. As the S League winner, Ichiriki starts the play-off with a one-win advantage, so this win made him 2-0 and made him the challenger to Iyama Yuta Kisei. That means that the two will meet in three successive title matches, making a super-series best-of-17 (a minimum of ten games will be played). Ichiriki is the youngest player to challenge for the Kisei title. Becoming the challenger earned him promotion to 8-dan (as of (November 10). The first game of the title match will be played on January 18 and 19.

Promotion: To 2-dan: Hirose Yuichi (30 wins, as of Nov. 3)

Correction: this post has been updated to reflect the fact that Rin Kaiho has born in 1942, not 1952.

AlphaGo-AlphaGo Game 15: New, different and possibly bad

Friday November 10, 2017

“I don’t like to call it weird, but in this game we’re going to see some new and different stuff that AlphaGo is doing with the joseki that I don’t 2017.11.10_ag-ag-thumb-15really understand and I don’t like it,” says Michael Redmond 9p in his commentary on Game 15. “It’ll be interesting to see if eventually I change my mind, but for now I’m going to say it’s a bad move.” Redmond adds that “We’ll also see another typical AlphaGo move later in the game that’s pretty exciting too.”

Redmond announces new series on AlphaGo Master vs AG Zero

Saturday November 4, 2017

“We were expecting DeepMind to make some sort of an announcement (about a new version of AlphaGo),” says Michael Redmond 9p, “But 802017.11.04_agzupdatethumb games was a big present.” (Self-taught AlphaGo Zero bests all previous versions in record time Redmond discusses AlphaGo Zero with the E-Journal’s Chris Garlock in a brief video announcing the launch of a new series of game commentaries. DeepMind released four sets of games for the self-taught AI, including training games, games against the Fan Hui version, the Lee Sedol version and the Master version, which defeated 60 top human opponents earlier this year. “I’m going to be looking at the games where Master plays Zero, mainly because Master is such a popular version of AlphaGo,” Redmond says. Master’s tactics, including big shimaris and emphasizing the center “people wanted to play, but were afraid because that way of playing is weak in territory. Master showed us some successful ways…and is still having an effect on how professionals play. So it’s going to be really interesting to see Master playing against a stronger version of AlphaGo.”

Monday October 30, 2017

The 2017 Space Coast Go Tournament was held on October 14 in the Community Resource Center in Rockledge, Florida. Rockledge is on the2017.10.29 Space Coast collage mainland near the Kennedy Space Center and Cocoa Beach.  Last year Hurricane Matthew delayed the games; this year Hurricane Irma blew through earlier.  Rockledge suffered a large amount of mostly minor damage.

The three round tournament drew 16 players including folks from Orlando, Sarasota, Port Orange, and the Palm Beaches.  A wide range of ranks split nicely into three groups: Dans, 1 to 8 kyu, and 8 to 28 kyu.

Top honors went to Jonathan Fisher, 4D, who won all three of his games.  Aaron Otero was the winner of the upper kyu division, also with three wins.  Joel Kickbusch, 10k, won two out of three to finish first in the lower kyu division.  He also won the raffle for a new Go set generously donated by Yellow Mountain Imports along with other prizes.  The first three players in each division chose books from Slate and Shell as their prizes.  Bart Lipofsky was the tournament director.
