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.”

The 2017 Space Coast Go Tournament was held on October 14 in the Community Resource Center in Rockledge, Florida.

The Power Report: Iyama defends Meijin, achieves second Grand Slam; Iyama makes good start in Oza; Iyama extends lead in Tengen; Yamashita makes Kisei playoff; Fujisawa evens score; First round completed in 73rd Honinbo League

Sunday October 29, 2017

by John Power, Japan Correspondent for the E-Journal2017.10.29_42 Meijin5 Iyama

Iyama defends Meijin, achieves second Grand Slam: The fifth game in the 42nd Meijin title match was held at the Atami Sekitei inn (below left), one of the traditional venues for the Meijin, in Atami City in Shizuoka 2017.10.29_43meijin5_8Prefecture on October 16 and 17. After winning the first game in the match, the defending champion, Takao Shinji Meijin, had lost three in a row, so he faced his first kadoban. The game got off to a stormy start, with Takao, who had white, capturing a large group of Iyama Yuta’s. Actually Iyama (right) could have made a second eye, but he didn’t like the result, so instead he discarded the group and tried to squeeze on the outside as compensation. As usual, it was a fierce game, and the lead switched back and forth. In the end, Iyama set up a ko to kill the white group surrounding his “captured” group, and Takao had to resign when he ran out of ko threats.

2017.10.29_42meijin5 TakaoLosing this title to Takao (left) last year cost Iyama his simultaneous grand slam, the first in Japanese go history. In the meantime, he defended his other six titles, so regaining the Meijin gave him his second grand slam, a first for. This is a first for go or shogi. Iyama maintained the first one for 197 days. Fans will be looking forward to his extending this. This is his 46th title, which leaves him in sixth place, one behind Kato Masao.

This success earned Iyama a report in the nightly news, which also revealed in passing that his tournament prize money now amounted to 1,000 million ten (about $9 million).

Iyama makes good start in Oza: Just three days after regaining his grand slam, Iyama was busy with maintenance, meeting the challenge of Ichiriki Ryo 7P for the 65th Oza title. The first game was played at the Yokohama Royal Park Hotel in Yokohama City, Kanagawa Prefecture, on October 20. Iyama drew white. The game started with a fierce struggle for the initiative, and fighting continued to the end. Iyama was able to take an edge, leading Ichiriki to resign after 168 moves.

Iyama extends lead in Tengen: The second game of the 43rd Tengen title match was played at the Hotel Emisia Sapporo in Sapporo City, Hokkaido, on October 27. Taking white, Iyama Yuta secured a resignation after 162 moves, making the game almost the same length as the Oza one reported above. Ichiriki Ryo (right) faces his first kadoban in the third game, scheduled for November 24. As least he has the better part of a month to consider how to righten his ship in his double challenge.

Yamashita makes Kisei playoff: The third game in the knock-out to decide the challenger in the 42nd Kisei tournament was played on October 27. Motoki Katsuya 8P had done well, moving up from bottom of the knock-out, as C League winner, past the B and C League winners, but his run came to a stop when he met Yamashita Keigo 9P, second-place-getter in the S League. Taking black, 2017.10.29_female-honinbo2 FujisawaYamashita won by resig. He will meet Ichiriki in the final, though the latter starts with a one-win advantage.

AlphaGo-AlphaGo Game 13: The large knight’s move enclosure workout

Sunday October 29, 2017

“This is a very different game, in that there are three corner enclosures,” says Michael Redmond 9p in his game commentary on AlphaGo-2017.10.27_AG-13AlphaGo Game 13. “Black isn’t playing a kakari, which is different from what human players do now. So we’re going to have kind of a workout in how to deal with the large knight’s move enclosure.”

Grandmaster Morozevich on go, computers and cheating

Sunday October 29, 2017

Alexander Morozevich was once live-rated world no. 1, but at the age of 40 the Russian grandmaster has dropped to world no. 79 and barely2017.10.29_morozevich-barsky plays classical events, reports chess24. In a recent interview he talked about what he’s currently up to, explaining his fascination with go and how he’s watched as computers have conquered that game just as they did chess during his career. “I see very similar processes in what Go is going through and what happened in chess 10-15 years ago…For now it’s not quite formalised, but gradually, I think, they’ll follow the same path that we followed in chess.” In the article, Morozevich also talks about what he sees as the chess world’s reluctance to take cheating seriously, despite computer “doping” being so much more powerful than drugs in other sports.

Inaugural Latin American Go Congress sparkles in Cancun

Wednesday October 25, 2017

Known worldwide for sparkling beaches and water, these attractions were but a pretty side element at the first Latin American Go Congress in Cancun, Mexico from October 13th to 15th. Sixty-four players from 15 countries played in the six-round 19th Ibero American Go 2017.10.25_Latin American Go CongressChampionship (CIG). After a slightly delayed start on the first day (familiar to many U.S. Go Congress participants), TD Milosh Trnka Rodriguez kept the McMahon event moving smoothly. Time limits were short to fit two rounds each day before lunch – generally 35 minutes per player plus 5 x 30 overtime. The overall winner was Kim Hyuneoo of Korea. The Ibero Championship (limited to citizens of the Ibero-American member states) was won by Fernando Aguilar 7d (below left) of Argentina, the perennial top player from the region.

The first Latin American Youth Go Championship was run by Siddhartha Avila of Mexico and had 16 players from six countries divided in two categories. Division A was won by Soomin Oh 2d from Korea and in Division B Shanti Ramírez 12 kyu from Mexico came out on top. In the first Pandanet Go Latin American Team Championship (PGLATC) Mexico bested guest Argentina in a 3-board match with a 2-1 score.

With generous international support, six pros attended: Enda Hideki 9P and Komatsu Daiki 2P from Japan; Cho Hye-yeon 9P and Youngshin Lee 5P from Korea; Mateusz Surma 1P from the European Go Federation; and Eric Lui 1P from the AGA with funding provided by the American Go Foundation. After the main games, the pros provided quick game analysis and each afternoon half of the players took on the pros in simuls. Few of the amateurs won!

aguilar_DSC0186There were lectures on pros games (including an especially lively one analyzing a victory over a fellow 9P by Cho Hye-yeon, 9P) and sessions on teaching go by a leading Korean expert from KIBA, Mr. Kwon Kapyong 8P. And, of course, there was lots of casual play and discussion of games whenever players sat around a board.

The evening events included Crazy Go (with 19 variants) on Friday night run by AGF President Terry Benson. Rengo Kriegspiel was run for the first time in Spanish. As usual, everybody won. On Saturday evening, The Surrounding Game film was screened.
Each of the three evenings included a round of the second Ibero-American Pair Go Championship – with many of the pros and the Congress Director playing – won by Samy Suastegui, 8k of Mexico and Youngshin Lee, 9P of Korea.
The Emporio hotel provided a classy setting for the event. There was an included opening dinner at the hotel, box lunches each day, and plenty of coffee and water. The closing dinner at Porfirios had a classic Mexican atmosphere – good food and mariachi music. There was even a little impromptu singing of Go songs. And a new one – in Spanish – written by Benson and Ester Monroy added to the canon.
Funding for the event came from the International Go Federation, Pandanet, Nihon Ki-in, Korean Baduk Association, American Go Association, American Go Foundation, and Mexico’s National University UNAM.

The Mexican Go Association Congress team led by Emil Garcia and including Marco Hernandez, Temilotzin Ibarra, Ester Monroy, Dafne Rios, with additional support from UNAM students staff and media team gave a good start to the tradition of Latin American Go Congresses.
The site of the 2018 event will be announced before the end of the year with Bogota, Colombia and Buenos Aires, Argentina the likely candidates. For those who like an international Congress diet, there is a new hearty entrée on the menu.
