Former AGA Board Chair David Weimer tipped us off about a forthcoming book with a go-themed cover. International Relations Theory, The Game-Theoretic Approach is by Andrew H. Kydd, a colleague of Weimer’s in the Political Science Department at the University of Wisconsin-Madison in Madison, WI. “Written for advanced undergraduate and graduate students, this is the first textbook on international relations theory to take a specifically game theoretic approach to the subject,” according to the book’s description on the Cambridge University Press website. “International relations theory is presented and analysed using simple games, which allow students to grasp the concepts and mechanisms involved with the rationalist approach without the distraction of complicated math.” The book is due out in March.
In-seong Hwang 8D’s online go school starts its fourth American season – and 11th European season – next month and is accepting new students now. Click here for details on the American Yunguseng Dojang and here for the European Yunguseng Dojang. A well-known top player in Europe, Hwang Inseong 8D trained at the Korean Yunguseng Academy, studied Go in Myong-ji University and worked for a baduk TV channel as commentator. The program consists of interactive online lectures, student league-play and game reviews on KGS. Students have access to all past lectures and reviews — more than 100 lectures and over 2,000 game review videos — as well as “personal go reports” to help students assess the progress they are making and the areas which need most work. “After just one year, the American league already has the biggest number of players, thanks to the members who bring their friends,” says Hwang. “Since we have more members, the next season league will be much more interesting and competitive!” Click here for details on the program, schedule and pricing.

The 2015 European Go Congress will be held in Liberec, the Czech Republic, from July 25th to August 8th. “I´d like to invite American go players to join us,” says Vladimir Danek, chief of the EGC 2015 Organizing Committee and president of the Czech Go Association. “The motto of this Go Congress is ‘Go, Fun and Relaxation’“ says Danek. “We want to make the Congress attractive for everybody.” Click here to check out their cool video. Liberec is 100 km north of Prague, “very close to Germany and Poland,” Danek adds. The Congress site is the Babylon Center, which, in addition to conference halls, hotel and restaurants, has attractions including the Aquapark, iQpark, bowling, golf simulator and other activities. “The large open terrace on the roof of Babylon will be a great place for meeting friends and playing friendly games,” Danek promises. Although the EGC runs for two weeks, “you can also play for just one week or visit us for a couple of days,” says Danek. Registration goes up after January 1.

Gato Go: “This photo (left) is from the Facebook page of one of the Ecuadorian players I met in Quito,” writes Bob Gilman.
In a surprise victory, Murakawa Daisuke 8P defeated Iyama Yuta 9P on December 16 to win the 62nd Oza. The Oza is Murakawa’s first major title. This is the first time a player from the Kansai Kiin has won the Oza since Hashimoto Shoji 9P did so 33 years ago in 1981. The final game was played in Toba, Mie Prefecture, Japan. The upset attracted a lot of attention in Japan, because former Oza Iyama Yuta currently dominates the domestic Japanese go scene.

“It’s interesting to read about the work of University of Edinburgh to use machine learning to improve the level of playing in computers, (Scottish Neural Network Takes Computer Go to Next Level 12/16/2014 EJ)” writes Nin Lei, Distinguished Engineer and CTO, Analytics and Big Data, STG IBM Systems and Technology Group. “However, the title in their article creates an impression that their research is creating a program that can beat the best human players. If their probability of guessing their next move is only 44%, then their chance of guessing it wrong is 56%. In a sequence of 10 moves, the chance of getting the complete sequence correctly is 0.44 ** 10, which is a very small number.” Noting that checkers “has been solved via machine learning,” Lei says that “it appears it is promising for go as well.” But because machine learning predicates that there is a pattern in the underlying data set, Lei warns that “it could be so complex that machine learning can only attain a certain level of accuracy. It seems to me a program needs to have very high level of accuracy before it can play a good game at strong human level.” Lei also says that “Since machine learning is based on pattern recognition, I wonder if a professional can trick the program by using moves that may not be optimally locally but will create patterns that the program has not seen before. I applaud the work they are doing,” Lei concludes. “It is innovative by using a different approach than the existing strong computer programs. It will be interesting to find out if someday they can come up with an algorithm that can improve the accuracy significantly.”
12/22: the chance of getting the complete sequence correctly has been corrected to 0.44 ** 10 (from 0.56).
Another series of classic go books has just been released by BadukTV, reports Shawn Ray (Clossius). The first set of four books was “The Profound and Mysterious,” a life-and-death exercise book written between 1347 and 1349, during the Yuan dynasty. The second and just-released series is “The Art of Closing,” a 6-book set filled with ancient problems put together by previous masters and translated by Cho Hye-yeon. “It is a level below that of ‘The Profound and Mysterious’ so players 5-kyu and stronger should be able to benefit greatly from it,” Ray tells the E-Journal. “Though I think anyone can take a lesson or two from it.” Click here to buy both as a bundle of all 10 of the books.

“One of the last bastions of human mastery over computers is about to fall to the relentless onslaught of machine learning algorithms,” according to a December 15 report in the MIT Technology review. Why Neural Networks Look Set to Thrash the Best Human Go Players for the First Time reviews the work of Christopher Clark and Amos Storkey at the University of Edinburgh in Scotland, who “have applied the same machine learning techniques that have transformed face recognition algorithms to the problem of finding the next move in a game of Go.”
“The question that these guys have trained a deep convolutional neural network to answer is: given a snapshot of a game between two Go experts, is it possible to predict the next move in the game?…Clark and Storkey used over 160,000 games between experts to generate a database of 16.5 million positions along with their next move. They used almost 15 million of these position-move pairs to train an eight-layer convolutional neural network to recognize which move these expert players made next…the trained network was able to predict the next move up to 44 percent of the time, ‘surpassing previous state of the art on this task by significant margins.’”
After just a few days training, Clark and Storkey’s neural network beat GNU Go almost 90 percent of the time in a run of 200 games, but against Fuego 1.1, it fared less well, winning only just over 10 percent of its games.
“There is no suggestion from Clark and Storkey that this approach will beat the best Go players in the world,” the report concludes. “But surely, it is only a matter of time before even Go players will have to bow to their computerized overlords.”
Thanks to John Goon for passing this along.

Go makes an appearance in the Netflix series “Borgia,” which is not to be confused with the similar series “The Borgias.” In the 29th minute of the third episode (“1497″) of the third season, Cesare Borgia , the illegitimate son of Pope Alexander VI (r. 1492-1503), uses “the game of strategy from the Orient, go,” to give a plan for his conquest of northern Italian states. He uses a thick go board with legs and colored glass beads to demonstrate his point. “The goal is to add as few men as possible; out-thinking your opponent rather than out-fighting him.” The winner does not eradicate his opponent, but rather entices him to surrender.

As noted in yesterday’s report, the US team beat Europe in the SportAccord World Mind Games Round 3 team match on December 13; click here for Ranka’s details on that match, and here for the interview with Danny Ko, one of the victorious American players.
Round 4 action on December 14 began with two games that would draw the line between the medal winners and non-winners in the women’s section. Both players from Chinese Taipei came up short: Joanne Missingham lost in just 111 moves to Kim Chaeyoung (Korea), while Cathy Chang narrowly lost to famed veteran Rui Naiwei of China; click here for the game commentary. In the afternoon, Rui Naiwei lost by half a point to Kim Chaeyoung who now goes on to play Yu Zhiying for the gold medal.
Chinese Taipei got off to a good start in the fourth round of the men’s team when Lin Li-Hsiang defeated eighteen-year old Chinese superstar Mi Yuting. Chinese Taipei’s upset hopes were dampened, however, when their leading player Chen Shih-Iuan lost a tightly fought game to China’s leading player Shi Yue on board one, and were then dashed when Tuo Jiaxi convincingly defeated Chang Che-Hao on board three. China now has four straight wins, and their remaining match is against North America. While China was struggling past Chinese Taipei, the North American team lost to the Korean team 0-3, so China’s chances of completing a clean sweep of all their matches when they play North America appear quite good.
Europe had no better luck against Japan than North America had against Korea. The Europeans fought hard, but Yuki Satoshi beat Fan Hui by a comfortable 7.5 points, Ida Atsushi beat Aleksandr Dinershteyn by a 14.5 points, and Seto Taiki beat Ilya Shikshin by resignation. Edited from longer reports on Ranka Online. Click here for the complete report on Round 4.

Update: The US team beat Europe in the team match on December 13; see report and links below for details.
The morning event on the second day of the SportAccord World Mind Games on December 12 was the second round of the women’s double knockout. The outcome was victory for both Chinese and both Koreans. Choi Jeong needed less than two hours to defeat Natalia Kovaleva by a wide margin. In a somewhat closer game China’s rookie King Yu Zhiying defeated Japan’s Women’s Honinbo Fujisawa Rina. Japan’s Okuda Aya then bowed in resignation to China’s Rui Naiwei after a long ko fight, and Joanne Missingham (right), trailing by a fraction of a stone with only two one-point moves left to play, resigned to Kim Chaeyoung.
In the men’s team matches, Korea’s Kang Dongyoon fell to China’s Tuo Jiaxi on Board 3, followed by Korean youngster Na Hyun’s loss to Mi Yuting of China, clinching the round for China. Park Younghoon saved face for Korea by playing to a narrow but secure victory over China’s top rated Shi Yue.
The Chinese women did equally well in round 3 of the women’s competition in the afternoon, with Yu Zhiying prevailing over Choi Jeong and Rui Naiwei defeating Kim Chaeyoung by the same fractional margin by which Kim had won in the morning. Four games were also played in the losers’ bracket, with good results for Chinese Taipei and mixed results for the rest of the world: Fujisawa Rina defeated Natalia Kovaleva; Joanne Missingham defeated Okuda Aya; Chinese Taipei’s Cathy Chang defeated North America’s Irene Sha; and in an all-Russian game, Svetlana Shikshina defeated Dina Burdakova. The losers of these four games have now been eliminated. Only the two Chinese players remain undefeated, and they will meet each other in round 4.
Preliminary Round 4 results from play on December 13: Joanne Missingham d. Jeong Choi of South Korea, Svetlana Shikshina of Russia lost to Chang Kai-Hsin and Yu Zhiying beat seasoned campaigner Rui Naiwei. In the men’s team event, China beat Japan across two boards, with Tuo Jiaxi and Yue Shi winning for China while Atsushi Ida won for Japan. The USA men’s team beat Europe across two boards, Huren Yang 1P beating Alexandr Dinershteyn 3P and Danny Ko 7D beating Ilya Shikshin 7D, while Fan Hui 2P defeated Mingjiu Jiang 7P.
