The Power Report (2/2): Iyama wins first Judan game; 73rd Honinbo League; 43rd Meijin League

3 ore 53 min fa

by John Power, special Japan correspondent for the E-Journal

Iyama wins first Judan game: The Judan best-of-five got off to a start on March 6. It was played at the same venue as the Women’s Meijin game, as detailed above. These two titles share a sponsor, the Sankei Nerwspaper, and it has been the practice in recent years to link them in this way. The challenger is Murakawa Daisuke 8P, who has been the top young player at the Kansai Ki-in for some time now. This is his fourth title match with Iyama. His first challenge was the only successful one: he scored 3-2 and took the 62nd Oza title from Iyama in 2014, but the following year he lost it to him 0-3. He also lost the 41st Gosei title match to Iyama by the same margin in 2016. This is the reverse of the usual pattern, in which a young player fails in his first challenge but does better later. Murakawa’s record so far against Iyama is three wins to 14 losses: his only wins have come in their first title-match clash.
In the first Judan game, Murakawa drew black in the nigiri. The tenor of the game was set quite early when Iyama played a cleverly timed sequence that turned an earlier move of his into an efficient forcing move. After that, the game developed peacefully for a while, but that was misleading; in the end, it turned into a capturing race between two large groups. This was won by Iyama, so Murakawa had to resign after 156 moves. The second game will be played on March 22.

73rd Honinbo League: The Honinbo League is one round and one game away from finishing. As before, Ida Atsushi 8P has the provisional lead, but he hasn’t yet played his sixth-round game against Yamashita Keigo 9P. Motoki is on 4-1. Yamashita on 3-2, and Ko Iso 8P on 4-2. One of these three will be the challenger. Results of recent games are listed below.
(March 1) Ko Iso 8P (B) beat Shibano Toramaru 7P by resig.
(March 8) Motoki Katsuya 8P (B) beat Yo Seiki 7P by resig.; Kobayashi Satoru 9P (B) beat Hane Naoki 9P by resig.

43rd Meijin League: After four rounds of the league, two players share the lead: Cho U 9P and Shibano Toramaru 7P. both 2-0 (both have already had their byes). Recent results:
(March 1) Hane Naoki 9P (W) beat Yamashita Keigo 9P by resig.; Cho U 9P (W) beat Murakawa Daisuke 8P by resig.
(March 8) Kono Rin 8P (B) beat Takao Shinji 9P by resig.
(March 15) Shibano beat Yo Seiki (don’t have details yet).

To 3-dan: Tanimiya Ayako (40 wins; as of Feb. 27). Tanimiya earned her promotion after 37 years as 2-dan.

From the Archives: Go Seigen vs Robert Ryder 1971 game record

5 ore 53 min fa

Robert M. Ryder, an active AGA administrator, kept meticulous organizational records as well as careful records of what seems to be the majority of his games. He played many others, and some names are easily recognized, as in this record of a game he played with Go Seigen in Murray Hill, New Jersey in November of 1971. Anyone familiar with Go Seigen’s visit or Robert Ryder’s activity in the AGA is encouraged to contact AGA Archivist Karoline Li at

AlphaGo vs. AlphaGo; Game 17: Fun with kos

22 ore 53 min fa

Michael Redmond 9p, hosted by the AGA E-Journal’s Chris Garlock, reviews the 17th game of the amazing AlphaGo vs. AlphaGoselfplay games. “There’s a bit of fun with kos,” says Redmond. “And there’s a new move that’s become popular in pro play. It’s an interesting and close game and AlphaGo finds a very unusual way to finish it off.”

“Master versus Master games are my favorite go videos” says Alek Erickson. “I love these self-play games,” agrees Melinda Green. “Amazing game and beautiful analysis,” adds GerSHAK.

The Power Report (1/2): Korea wins Nong Shim Cup; Fujisawa defends 30th Women’s Meijin; Kato & Iyama win Pair Go

Dom, 18/03/2018 - 23:00

by John Power, special Japan correspondent for the E-Journal

Korea wins Nong Shim Cup:
  The final round of the 19th Nong Shim Spicy Noodles Cup was held in Shanghai from February 26 to March 1. Recently, victory in this three-way team tournament had been monopolized by China, but this time they were thwarted by Korea.
To recap, the first Korean player, Shin Min-jun 6P, gave his team a great start by winning all four games in the opening round, held from September 19 to 22. In the second round, held from November 24 to 28, he picked up two more wins before losing to Dang Yifei of China (at right in photo). Dang closed out this round with two more wins, so only two players had any success in the first two rounds.
In the first game of the final round, Game 10, Dang played Iyama Yuta 9P of Japan, who was his country’s last hope. Dang (W) won by resignation, so this was another international failure for Iyama, following on his loss in the LG final. In Game 11, played on February 27, Dang (W) beat Shin Jinseo 8P of Korea by resignation so he extended his winning streak to five games. In game 12 (February 28), Kim Jiseok 9P of Korea (W) scored a dramatic win over Dang by just half a point, so he prevented Dang from matching Shin’s record. In game 13, played on March 1, Kim (B) beat China’s top board, Ke Jie 9P by resignation. This secured Korea its first victory in the Nong Shim Cup since the 14th term without having to call upon their top board, Park Junghwan. Korea scored eight wins to three losses, China 5-5, and Japan 0-5. Japan came third for the 12thyear in a row, but it was only the second time it failed to pick up even one win.

Fujisawa defends 30th Women’s Meijin: Recently, most of the women’s title matches have featured Xie Yimin playing Fujisawa Rina, but this year’s Women’s Meijin title match was different, with a member of an older generation trying to make a comeback. The challenger was Yashiro Kumiko (below left), who won a couple of titles over a decade ago, and the defender was Fujisawa Rina, who holds three of the top five women’s titles. The first game was played on February 28 in the Arisu Building at the Heian Jogakuin University, an Anglican-linked women’s university also known as St. Agnes’ University. The Arisu Building is a former nobleman’s resident that is on the campus. According to Go Weekly, Fujisawa’s play “overflowed with fighting spirit.” She held the initiative throughout and forced a resignation after 196 moves (she had white). The second game, which was played on the campus of the Osaka University of Commerce on March 7, developed differently, with Yashiro taking the lead. However, she let Fujisawa pull off an upset late in the game and win by 3.5 points. This meant that Fujisawa defended her title with straight wins. Surprisingly, this is her first successful defence, which is not what you would expect of a player who not so long ago held four of the top five women’s titles. First prize is 3,500,000 yen (about $32,000).

Kato & Iyama win Pair Go: The final of the Professional Pair Go Championship 2018 was held at the Nihon Ki-in in Ichigaya, Tokyo, on March 4. This is a knockout tournament, with 16 pairs competing. Reaching the final were the Kato Keiko 6P/Iyama Yuta 9P pair and the Suzuki Ayumi 7 P/Ko Iso 9P pair. The latter drew black in the nigiri, but lost a game full of hectic fighting. They resigned after 218 moves.

Tomorrow: Iyama wins first Judan game; 73rd Honinbo League; 43rd Meijin League


San Diego club promotes go at Cherry Blossom Festival

Dom, 18/03/2018 - 21:00

For the seventh year in a row, the San Diego Go Club had several tables for demonstrating and teaching go during the annual Cherry Blossom Festival this weekend at the Japanese Friendship Garden in Balboa Park. This year the festival stretched over three days: Friday – Sunday. The club was given a choice spot, just inside the entrance, right next to a crowd favorite: the large well-stocked koi pond. Thousands of people streamed through the garden, even coming through a light rain on Saturday (Note: plastic go stones do not float on wet vinyl go boards.)

Club members played demonstration games against go playing visitors as well as taught go to people who had heard of the game but never played. Dozens of copies of “A Way to Go,” the go pamphlet given to AGA chapters every year by the AGF, were distributed. The club added several new potential players to its email list.

Ki Choi tops Davis/Sacramento Go Club Spring Tournament

Dom, 18/03/2018 - 17:00

Chicago Math Teachers Learn Go

Sab, 17/03/2018 - 21:59

“As an educator, I have been advocating using go as a math manipulative in schools, and dreaming about the day that students in every classroom will learn go,” writes 2015 AGF Teacher of the Year Xinming Simon Guo. At the Metropolitan Mathematics Conference of Workshops, an annual event for math educators in the greater Chicago area, professor Xiuwen Wu and Guo organized a workshop for teachers in February. “Teachers in the workshop had never heard about go. We first showed teachers how to play, and then they explored how the game is related to math standards in schools. After several games on mini boards, I shared the most important conclusion from our prior research — about 60% of math content from kindergarten to third grade can be covered in just one game. I also showed some authentic classroom videos on kids learning and playing go for further discussion.”

“My co-speaker professor Wu shared her experience on how to use go in  teacher preparation methods courses, and shared pre-service teachers’ suggestions on how to integrate go in math instruction. Finally, she highlighted the benefits of this game-based learning method, including student ownership of learning, wide coverage of math standards, low cost and easy maintenance. Classroom teachers, especially in early elementary grades, are in the ideal position to implement this teaching method. We need to raise awareness among educators involved in making decisions about effective math learning tools and materials, including teachers, school administrators, district education directors and superintendents. As educators learn about go, they will come to see the ease with which teachers can use the game to teach every learner a multitude of math concepts and skills,” adds Guo. - Paul Barchilon, EJ Youth Editor.  Photo by Xinming Simon Guo


Redmond Reviews: Michael Redmond 9P vs Rin Kaiho 9P

Lun, 12/03/2018 - 05:52

As a young player, Michael Redmond was in the legendary Rin Kaiho’s study group –where Rin’s wife served them all a meal before they commenced playing go –) but in this week’s video game commentary, Redmond faces Rin in a Gosei tournament game, Redmond’s first tournament game of the year. “It was an unusual chance to get to play against such a famous player so early,” says Redmond, “and very special, as well.” Chris Garlock of the AGA E-Journal hosts; click here for the video.

“It’s amazing how one small mistake in midgame can make the difference between a white collapse and white advantage,” says Keldor314. “Go is just scary that way.”

“Another great review, thanks,” says Ewen Pearson. “Just joined the AGA. Are there SGFs for all of Michael Redmond’s reviews on If so where are they?” Click here for all the Redmond Reviews.

S&S news: “Rethinking Opening Strategy” #1 new release; Iwamoto classic returns

Ven, 09/03/2018 - 00:00

Slate & Shell’s new book, “Rethinking Opening Strategy: AlphaGo’s Impact on Pro Play” by Yuan Zhou, was recently the number one new release in board games on Amazon, reports publisher Bill Cobb. “It is selling like hot cakes” Cobb tells the E-Journal.

In other Slate and Shell news, Iwamoto Kaoru’s classic book “Invasion in Common Go Positions,” is available again. This book was originally published as part of “Keshi and Uchikomi: Reduction and Invasion in Go.” After substantial revision, the “Keshi” section was republished as “Invasions.” This definitive work analyzes both how to invade common situations in go games and how to defend against such invasions. “These are normal situations that regularly occur, making the discussion useful in everyday play,” says Cobb.



Historic go at Princeton’s Fine Hall

Gio, 08/03/2018 - 21:00

In the January 10 edition of the Princeton Alumni Weekly, there is an article by Elyse Graham called “Adventures in Fine Hall: The weirdness of math’s golden age.”  She writes of the hijinks of the great mathematicians of the 1930s gathering in the Princeton University Mathematics Department and the Institute of Advanced Studies: Albert Einstein, John von Neumann, Kurt Friedrich Gödel, Hermann Klaus Hugo Weyl.

Speaking of Fine Hall, the center of mathematics at Princeton, she writes, “To blow off steam, many students got into games, as players and creators both…. During the day, a visitor to the common room might see the nation’s mathematical brain trust absorbed in games of Go, bridge, double solitaire, or chess, played classic or whimsical variants.” She also writes that “A favorite was a double-blind variant of chess called Kriegspiel,” which Terry Benson has adapted for go at his Crazy Go nights each year at the U.S. Go Congress. “The boast went out that Fine Hall ‘could produce a champion in any game that was played sitting down.’”

1971 Honinbo Tournament Game 2 video released

Mar, 06/03/2018 - 18:00

A new video compresses the second game of the historic 1971 Honinbo Tournament into a compelling 4 1/2 minute sequence, complete with music by the Blue Dot Sessions. Ishida Yoshio, just 22, entered the Honinbo League for the first time that year, won it, and went on to beat the established Honinbo, Rin Kaiho, in the title match. The second game is thought to be the most exciting of the match. “The focus of this project was to highlight the wonderful graphic beauty of a flowing go game rather than a analysis of the moves,” says video creator Mike Garland.


AlphaGo Zero vs. Master; Game 7: The magic show

Mar, 06/03/2018 - 04:42

AG Zero comes up with a new variation to handle Master’s shimari, “and then there’s a bit of a magic show, in which Zero does all sorts of stuff inside Master’s moyo,” says Michael Redmond 9P in his commentary. “It’s pretty hard to believe.”

“The relaxed and fun atmosphere (Redmond and Garlock) have when doing these reviews is great,” says Rory Mitchell. “It keeps things light amidst all the intense thinking required, and ultimately makes these videos very rewatchable.” Adds GerSHAK, “Absolutely BEAUTIFUL game to watch. Loved the post-game summary of white’s most exciting moves, too.”
