Yunzi Stones and Lead: An Update

Friday February 14, 2014

“I bought ‘Yunzi Stones’ from Yellow Mountain Imports as a gift for my young children so we can play baduk together,” wrote EJ reader Jason Lee recently. “Later on after ordering, I saw online that this kind of stone can contain lead. So when my order arrived I got a lead test kit from the local hardware store to check them for safety. It turns out that the stones sent to me did contain lead. This is unsafe for my children to use and maybe me too. I wrote about my experience here. Thank you for the great work (the EJ does) for baduk players. I read the website every week.”

The EJ originally reported on this in 2008 (Go Review: Chinese Go Stones 2/4/2008) and we later reported (Yunzi Stones Now Lead-Free 6/23/2008 EJ) that YMI had contacted the manufacturer, who had agreed to eliminate lead from the manufacturing process of yunzi stones, which are special go pieces manufactured in the Chinese province of Yunnan. Apparently the manufacturer did not completely eliminate the lead, instead reducing it below the levels recommended by the Consumer Products Safety Commission; see below for details.

Yellow Mountain Imports responds: “Thanks for reaching out to us. We thought we had resolved this many years back when we had gone through all the reformulation and subsequent tests with the Yunnan Weiqi factory so obviously we were concerned. We take product safety seriously so when we heard these new complaints, we contacted the Yunnan Weiqi Factory immediately. They were equally concerned and arranged for a current official radio spectrometry test. The black stones tested positive at 0.005% (50 parts per million). Lead was also found in the white stones, at an even lower concentration, less than 0.002 (20 ppm). The Yunnan Weiqi Factory reformulated Yunzi stones to be within safe levels as per our request many years ago, while maintaining as much as the original qualities as possible, but it turns out that they cannot eliminate it completely. Lead makes the stones more durable and less brittle. These levels are well below the 0.009 (90 ppm) level recommended by the Consumer Products Safety Commission, but we do not claim that they are lead-free. Anyone who has purchased Yunzi stones and wants to return them can do so and should contact us.” Email customerservice@ymimports.com with any questions or concerns.

Thursday February 13, 2014

Myungwan Kim 9P (left) has opened his own go school, the American Go Institute in the city of Arcadia east of Los Angeles. Kim tells the EJ the Institute offers comprehensive and specialized training programs for kids to approach go and is dedicated to helping and developing kids’ potential. “With expert instruction and a proven training methodology, the Institute provides a true foundation for future success,” Kim said. Kim moved to the US in 2008 to promote go at the behest of the Korea Baduk Association and has been instrumental in starting the AGA’s professional certification program. For the stronger players, the Institute’s methodology involves a great deal of deep reading practice and life and death work in keeping with the latest techniques used in Asian go schools, as well as face-to-face play and review. Beginners are also welcome. In addition to Kim, top level former insei Evan Cho (right) is teaching at the Institute. For more information, call 626-538-4286 or e-mail americangoinstitute@gmail.com.

The Power Report: January Update: Kato to Challenge for Women’s Meijin; Yamashita Leads In Honinbo League; Meijin League; Iyama Misses Shot at Grand Slam; Chisato Cup; Xie Defends Women’s Kisei; Annual Promotions

Thursday February 13, 2014

by John Power, EJ Japan Correspondent

January in Japan: I failed to submit a report last month, so I would like to make up for it with a review of the first month of professional go in Japan this year.

Kato to Challenge for Women’s Meijin: Kato Keiko 6P (right) hung on to her lead in the 26th Women’s Meijin League and will challenge Xie Yimin for the title. In the final round, held on January 9, she beat Okuda Aya 3P (W) by half a point to end up on 5-1, one point clear of the field. The match starts on March 5.   Actually, this was Kato’s first game for three months. As mentioned in an earlier report, she took the winter off to have her second child. This is Kato’s first title match for six years (she lost the 20th Women’s Meijin title to the challenger, who was Xie Yimin).  She won the title the previous term and the 10th Strongest Woman Player title in 2008. She is married to Mizokami Tomochika 8P.
Other results in the final round: Mukai Chiaki, Women’s Honinbo, (W) beat Yoshida Mika 8P by resig.; Suzuki Ayumi 6P (B) beat Chinen Kaori 4P by 3.5 points. Mukai and Suzuki, both on 4-1, took 2nd and 3rd places respectively. The other player to keep her place in the league was Chinen, on 3-3. Okuda (1-5), Yoshida (2-4), and Ishii Akane 2P (2-4) all dropped out.

Yamashita Leads In Honinbo League: A win over Yuki Satoshi at the end of last year gave Yamashita Keigo (left) a share of the lead with Kono Rin in the 69th Honinbo League; both were on 3-0 and were the only undefeated players.  However, in the fourth round, played in January, Yamashita beat league newcomer Yo Seiki while Kono lost to Cho U, so Yamashita now has the sole lead. The other league newcomer, Ida Atsushi,  shares second place with Kono and Cho U. Games played since my last report are given below.
(26 December) Yamashita Keigo 9P (W) beat Yuki Satoshi Judan by resig.
(January 9) Ida Atsushi 7P (B) beat Takao Shinji 9P by half a point.
(January 16) Cho U 9P (W) beat Kono Rin 9P by half a point; Sakai Hideyuki 8P (B) beat Yuki Satoshi by resig.
(January 23) Yamashita (W) beat Yo Seiki 7P by resig.

Meijin League: Three of the four games in the second round of the 39th Meijin League were played on January 9. At this point, Kono Rin (right) has the provisional lead with 2-0, but the winner of the fourth game, between Yamashita Keigo and Takao Shinji, will draw even with him.
(January 9): Kono Rin 9P (B) beat Hane Naoki 9P by resig.; Cho U 9P (W) beat Murakawa Daisuke 7P by resig.; Ko Iso 8P (W) beat Yuki Satoshi Judan by resig.

Iyama Misses Shot at Grand Slam: Recently, with Iyama Yuta (left) holding six titles, there had been a lot of speculation about whether he would become the first player to score a genuine grand slam of the top seven titles, that is, holding them all concurrently instead of cumulatively. In the past, players have not been able to maintain a big tally of concurrent titles for very long because of the wear and tear of constant title matches, so if Iyama is going to have a try at it, the sooner the better. This year he seemed to have a good chance, as he had reached the play-off to decide the challenger for the only top-seven title he didn’t have, the Judan, and his opponent was a player, Takao Shinji, against whom he had a very good record. The play-off was held on Iyama’s home ground, at the Kansai Headquarters of the Nihon Ki-in, on January 23. The game was a difficult one, with a series of swaps, but Takao, playing white, prevailed by 5.5 points. Takao gets a chance to win back the title that he lost to Cho U in 2009. To keep the dream alive, Iyama will have to try again next year, but he must first defend all his titles this year. There is no precedent in Japan for such a long winning streak in title matches. The first game of the title match between Takao and Yuki Satoshi Judan will be played on March 4.

Chisato Cup:  This is a special tournament being held to commemorate the 25th anniversary of the founding of the Chisato corporation, which makes uniforms, helmets, and various other work-related items. Participants were 16 young players recommended by the sponsor. First prize is two million yen. The time allowance is the same as for the NHK Cup, that is, 30 seconds per move plus ten minutes extra time in one-minute units.  The first two rounds were held on January 17th and the following players have reached the semifinals: Suzuki Shinji 4P, Hirata Tomoya 3P, Kimoto Katsuya 2P, and Fujisawa Rina 2P. Fujisawa is the granddaughter of Fujisawa Shuko. The semifinals and final will be held on March 1 and 2.

Xie Defends Women’s Kisei: On her previous challenge, two years ago, Aoki Kikuyo 8P managed to take the Women’s Kisei title from the Xie Yimin (right) , the top woman player in Japan. Xie regained the title last year, but Aoki was back again as challenger. This time she did not do so well, however, and Xie has defended her title with straight wins. The first game was played on January 23; taking white Xie forced a resignation. In the second game, played on January 30, Xie had a different color but the result was the same, a resignation by Aoki. Actually, Aoki had the better of it for most of the first game; after a severe attack, she had a large enemy group at her mercy, but she failed to deliver the coup de grace. This is Xie’s 17th title.

Annual Promotions
In January every year there are a number of promotions for the top prize-money winners of the previous year among players from 1- to 6-dan. The following promotions became effective on February 1.
To 7-dan: Shida Tatsuya (only the top 6-dan is promoted); To 6-dan: Kawada Kohei, Ohashi Naruya; To 5-dan: Tajima Shingo, Sakamoto Yasuo; To 4-dan: Ichiriki Ryo, Muramatsu Hiroki; To 3-dan: Kimoto Katsuya, Adachi Toshimasa; To 2-dan: Kikuchi Masatoshi, Onishi Kenya.
There were also two promotions by the cumulative-wins system. Shimoji Gensho (120 wins) earned promotion to 7-dan as of December 26. With 50 wins, Ms. Makihata Taeko was promoted to 4-dan as of January 31. (Usually the date of the promotion is the day after the game that secured it, as the details have to be confirmed by the Ki-on office.)
Tomorrow: Iyama Leads 3-0 in Kisei Title Match; Kisei Game One Trivia; Yamashita and Cho U Share Lead in Meijin League; Shi Yue Wins New Year’s Tournament; A Promotion and a Retirement

Go Spotting: Alex Wissner-Gross’ TED Talk

Saturday February 8, 2014

Go is cited in a brand new TED Talk video by physicist and computer scientist Alex Wissner-Gross (right). In “A new equation for intelligence,” Wissner-Gross attempts to give a definition and a formula for intelligence. “His main thesis seems to say that ‘Intelligence is a physical process that resists future confinement, and attempts to maximize the options for diversity,’ ” writes James Michali of the Springs Go Club in Colorado, one of several readers who sent this in. “Among several examples to illustrate this thesis, Alex uses the game of go to make his argument concrete,” says Michali.
Thanks also to James Chao and Cynthia Gaty.

The Go Quiz Returns!

Saturday February 8, 2014

by Keith Arnold, HKA
I am delighted to have been asked to return as AGA Quizmaster and look forward to bringing you a whole new batch of weekly brain-teasers that will test your knowledge of the go world and its fascinating history. I will be ably assisted by quiz veteran Phil Waldron 6 dan and Daniel Chou 6 dan; if you notice clever questions of a new style, they will deserve the credit, while all errors (and unfortunate puns) will remain my responsibility.  Please remember to submit your answers on or before Thursday each week. Let the games begin!

Since we’re in a self-referential mood, let’s make our first effort close to home: How many books are in Keith Arnold’s go library?  For the purpose of this question, all languages are allowed, including duplicates as long as they are materially different (translations, revised editions with different covers) as opposed to the deranged “doubles” of an obsessed collector.  Our E-Journal editor – who interviewed me at my home some years ago — will be as surprised as I am that the number of go books finally exceeds my voluminous collection of books regarding the War Between the States. Is the number 600-700, 700-800, 800-900 or more than 900?  Click here to make your guess and, as always, feel free to include your comments, rude or otherwise, as we do award extra points for clever responses. photo: Arnold at the 2012 US Go Congress; photo by Phil Straus
