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

Monday March 19, 2018

by John Power, special Japan correspondent for the E-Journal2018.03.19_56jyudan1_4

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. 2018.03.19_56jyudan1_5Murakawa’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

Monday March 19, 2018

IMG_1292Robert 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

San Diego club promotes go at Cherry Blossom Festival

Sunday March 18, 2018

For the seventh year in a row, the San Diego Go Club had several tables for demonstrating and teaching go during the annual 2018.03.18_san-diego-cherry-blossomCherry 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.

Chicago Math Teachers Learn Go

Saturday March 17, 2018

IMG_20180210_105212038“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

Monday March 12, 2018

As a young player, Michael Redmond was in the legendary Rin Kaiho’s study group –where Rin’s wife served them all a meal 2018.03.11_redmond-rin-goseibefore 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.

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.
