Late in the afternoon of December 17, go players at the 2014 SportAccord World Mind Games attended their second awards ceremony in the Beijing International Convention Center. This time the awards for pair go were given out. China’s Yu Zhiying and Mi Yuting collected their second gold medals, Korea’s Choi Jeong and Na Hyun collected their first and second silver medals, respectively, and China’s Cathy Chang (more formally, Chang Kai-Hsin) and Lin Li-Hsiang received their first bronze medals.
Medals were also awarded for individual contract bridge, Basque system chess, super-blitz draughts, checkers, and xiangqi. Four countries picked up their first gold medals here: Monaco, for whom Geir Helgemo came through in open bridge; Cameroon, whose draughts star Jean Marc Ndjofang won the men’s superblitz; Vietnam, whose Ngyuen Hoang-Yen shone in women’s xiangqi; and Italy, which proved to have the world’s top two checkers players.
All told there were 24 separate events in this year’s world mind games, and mind athletes from 20 different countries and territories won medals. Between them, China and Russia took the gold medals in half the events, winning six each. Russia outpointed China in silver medals, but China outpointed Russia in bronze, won medals in a greater number of disciplines (all but draughts), and won the greater total number of medals – by a wide margin if China’s medals in the team and pair events in go and bridge are counted as multiple medals. All of Russia’s medals came in individual competition in chess and draughts. Full results and further details can be found on the SportAccord schedule and results page and news page.
At the closing ceremony at the V-Continent Beijing Parkview Wuzhou hotel, Mr Hai Zhenwen, deputy secretary general of the organizing committee, praised the successful conclusion of the four-year series of SportAccord World Mind Games in Beijing. China’s former ace weightlifter Ma Wenguang, representing SportAccord Asia/Pacific, thanked the city of Beijing and expressed a hope that world mind games would continue elsewhere in the Asia-Pacific area in the future. Mr Vlad Marinescu, Director General of SportAccord, said that he had been humbled at finding himself in the midst of so many geniuses but inspired by the enthusiasm of Beijing’s children, and noted that on the publicity front, this year the games had achieved a 50% growth over last year on all media platforms. Mr Chen Jie, deputy director of the Beijing Municipal Bureau of Sports, thanked the organizers for their hard work, after which he and Mr Marinescu exchanged gifts, and then everyone settled down to a good dinner.

This is the game in which China’s Yu Zhiying and Mi Yuting won the gold meal in pair go by defeating Korea’s Kim Choi Jeong and Na Hyun. Click here for the sgf game file.
Black 37 (A in diagram 1, played by Choi) defends against a double peep at B, but lets white jump to C. Black is playing too safe. She should have capped at 1 in diagram 2. If white peeps, pushes, and cuts as shown in the diagram, black can give up two stones, after which white will be unable to reach the center. Then black can develop on a truly large scale by pressing white down on the lower side as shown (moves from 11 to 15 in diagram 2).
Black 43 (played by Na) was also too conservative. Black should have occupied white 52, the junction point of his framework on the right side and the white framework on the lower side. When white got to play 52, the Chinese pair had a territorial lead.
White 64 may have been an overextension. Black 65 immediately started to threaten white’s thin position. With 66, white began dancing around to protect the weak white stones in this area and the weak white group at the top. But white danced successfully. By the time white played 92, white’s weak stones and group were out of danger.
Black 111 (Na) may have been the decisive mistake. Before playing here, black could have made sente moves at 112 and 150. Instead, white was able to play 112 and 148-150 in sente, gaining approximately seven points.
Black’s last chance was to start the ko at 157, but black lacked the necessary ko threats. Black 159 was inadequate. White simply ended the ko with 160, gaining as much at the top as was lost in the bottom left corner. When black renewed the ko challenge at 183, white accepted by cutting at 184. When Yu took the ko with white 194, Na decided that black’s prospects too poor to continue and were offered to resign, and his partner agreed.

This is the game in which Chinese Taipei’s Chang Kai-Hsin (Cathy Chang) and Lin Li-Hsiang (White) won the bronze gold meal in pair go by defeating Japan’s Fujisawa Rina and Ida Atsushi (Black). Click here for the sgf game file.
The opening pattern up to white 8 has become very popular quite recently and appeared in several SportAccord games.
Up through black 71 (the marked stone in diagram 1) the position is about even. White appears to have more territory, but the white position on the lower side is thin and can easily be invaded, so black is not behind. In fact, if black had played 71 at 1 in diagram 2, black might well have been ahead. White cannot cut black apart. Given the continuation through black 9, black is solidly linked up and the white group cannot make two eyes on the right side, so black will be able to attack it in the center.
The move that Ida Atsushi chose for black 71 was readily answered by white 72, and black 73 let white break up black’s right side territory in sente with 74 and 76. Aside from sling territory, black was placed on the defensive, and would be hampered in going deeper into the white territory at the bottom.
From this point on, the fighting in the center became quite confused. White’s top group seemed to be in trouble, but it could never be killed unconditionally, except at the sacrifice of an even larger black group. When white 168 connected the ko in the top left, white had a clear territorial lead.
By white 186 black’s position had become untenable and the Japanese pair resigned.

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.

This is the game in which the Russian brother-sister pair of Ilya Shikshin and Svetlana Shikshina, both former European champions, defeated Russia’s Natalia Kovaleva and France’s Fan Hui to take fifth place in the mixed pairs competition. Click here for the sgf game file.
White 8 to 16 are one variation of a popular joseki. This variation and others appeared several times during the week of World Mind Games.
White 38 (the marked stone in diagram 1) was a mistake. The critical issue here is the relative strength of the groups in the center. If the white pair had played as shown in diagram 2, their own center group would have had the upper hand, and they would then have been free to deal with the loose black framework on the right side.
If black had captured white 98, the white group in the center would have been in serious trouble. Apparently Ilya decided that invading the bottom right corner first would be a safer way to win, but this is not necessarily true. If white had played 123 in sente before black did so, then given the same continuation on the rest of the board, the final margin would have been only half a point. As it was, black won by 1-3/4 stones, or 2-1/2 points.

The Irish Championship of 2014 is not yet finished, but a date has been set for the event of next year. On the weekend of January 10th – 11th the Top 8 kick-off event will take place at the Ballsbridge Hotel, Dublin. The Annual General meeting will be held on the evening of Saturday the 10th of January. Exact time and venue to be confirmed, but it will either be in or near to the Top 8 venue.
The final round of pair go competition at the 4th SportAccord World Mind Games was played in the morning of December 17. Deputy referee Michael Redmond gave the starting instructions. The gold medal game was televised, so Michael next moved into the broadcast booth to do the live commentary.
That game started well for the Chinese pair, due in particular to a couple of overly conservative Korean moves (Choi Jeong’s black 37 and Na Hyun’s black 43, click here to download the sgf file.) in the opening. The Koreans’ conservative style gave their opponents Yu Zhiying and Mi Yuting a territorial lead. Although the Korean pair gained ground through good play in the center, forcing the Chinese to go on the defensive, the Chinese pair handled their weak stones very well and maintained their advantage. Then as the endgame began the Koreans missed making a couple of valuable sente moves and found themselves definitely behind in territory. Although they tried to catch up in a ko fight, they lacked adequate ammunition, lost the ko, and resigned. China had swept all the gold medals in go. Korea’s silver is at least an improvement on the bronze the Korean pair got last year.
The battle for this year’s bronze was won by Chinese Taipei. The Japanese pair (Fujisawa Rina and Ida Atsushi) began well enough, but gave away territory in order to embark on a long and confused fight that did not turn out well for them, and eventually had to resign. The new pair from Chinese Taipei (Cathy Chang and Lin Li-Hsiang) played very well this year, as a different pair from Chinese Taipei had also done in winning the silver medal last year.
The all-European battle for fifth place was waged for the larger monetary prize (5000 USD) instead of medals. After some initial fighting, it turned into a close but peaceful contest of very large territories. The winners, with one stone or two points to spare, were former European champions Svetlana Shikshina and Ilya Shikshin. Their opponents Natalia Kovaleva and Fan Hui took sixth place (4000 USD).

“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.
China has swept the SportAccord 2014 World Mind Games go competition, winning gold in the men’s team and women’s individual events. Tuo Jiaxi, Mi Yuting and Shi Yue (right) easily dispatched the US team in the final match to clinch their gold medals.
