Go Spotting: Leibniz calls go “ingenious and quite difficult”

“I easily believe that the magnitude of the Board and the quantity of pieces render this game quite ingenious and quite difficult,” wrote the 2015.06.06_Leibniz_WeiqiGerman polymath and philosopher Gottfried Wilhelm von Leibniz about go in 1710. Leibniz, in “Miscellanea Berolinensia” goes on to note “the singular principle” of go is not “the death of the enemy, but only to push him to the limits of the Table,” which, while not perhaps technically accurate, certainly gets at the heart of the game, though he goes on to draw the questionable conclusion that the game’s inventor “abhorrent of murder, wished to obtain a victory not soiled by blood.” Leibniz learned about go from the book “Christian Expedition among the Chinese,” by Nicolas Trigault, a missionary to China in 1600s.

The Power Report (III): Aizu Central Hospital Cup; 2nd Mlily Cup; O Meien wins 1,000 games

by John Power, Japan Correspondent for the E-Journal2015.06.08_Aizu O & Xie

Aizu Central Hospital Cup: Xie Yimin (right), Women’s Meijin, will meet O Keii 2P (left), the daughter of O Rissei 9P, in the final of the 2nd Aizu Central Hospital Cup. In the semifinals, played on June 7, Xie (W) beat the previous winner Fujisawa Rina 2P by resignation and O (B) beat Kato Keiko 6P by 4.5 points. The final, the only two-day game in women’s go, will be held on July 2 and 3.

2nd Mlily Cup: Nineteen Japanese players took part in the open preliminary tournament for the 2nd Mlily Cup, held at the Chinese Qiyuan (Ki-in) in Beijing from May 22 to 26. They were made up of ten male professionals, five female professionals, and four amateurs. No Japanese players won a seat in the main tournament, but Yo Seiki 7P, Fujisawa Rina 2P and Xie Yimin 6P did reach the semifinals. In the second round, Fujisawa scored a memorable win over the world’s top-rated woman player, Choe Cheong 5P of Korea. Fujisawa, playing white, had fallen behind but found a brilliancy, a move that looked like a suicide move but which turned the game around. Fujisawa commented that Choe, who is two years her senior, is definitely stronger than her, but she was happy to pick up a win.

O Meien wins 1,000 games: A win on June 4 was O Meien’s 1,000th as a pro. He is the 16th player at the Nihon Ki-in to reach this landmark, and it took him 38 years two months. With 571 losses, two jigos and two no-results, his winning percentage is 63.7.

Promotion: To 8-dan: Kitano Ryo (150 wins) (as of May 29)

Correction: In my report about Otake Hideo’s decoration (5/3 EJ), I wrote that he was the 23rd go player to be so honoured. Go Weekly subsequently amended the list it published; actually 25 players have won decorations.

One broken leg and a Taiwanese import – 20th LG Cup

The 20th LG Cup kicked off with the round of 32 on June 8, 2015 in Kangwon, Korea.

Fans eschew Won Seongjin 9 dan for Lee Sedol 9 dan and Lee Changho 9 dan at the 20th LG Cup gala.

As always, a lavish banquet proceeded official matches. Young fans didn’t waste any time acquiring autographs from their favorite Go celebrities.

Poor Choi Cheolhan turned up in a wheelchair having recently injured his leg in a perhaps not so friendly football match.

He must have been in a lot of pain throughout his games as he is still waiting on the final surgery.

Round of 32

Not even a fractured ankle can stop Choi Cheolhan 9 dan take on Ke Jie 9 dan at the 20th LG Cup.

Not even a fractured ankle could stop Choi Cheolhan 9 dan from taking on Ke Jie 9 dan at the 20th LG Cup.

Korea dominated the first day of play, winning 10 out of the 16 matches.

However, the two big Lees, Lee Changho 9p and Lee Sedol 9p, were both eliminated.

The only Japanese professional to survive was Kansai Kiin’s Yo Seiki (Taiwanese name – Yu Zhengqi) 7p.

Interestingly, Yo first turned pro in Taiwan before deciding to pursue a career on the Japanese professional circuit.

Taiwanese professional, Lin Junyan 6p also made it through the first day, defeating sentimental favorite, Lee Changho 9p.

Much to Chinese fans’ dismay, after the first day, only 4 Chinese players remained still in play.

Round of 16

China’s luck vastly improved during the next round with Tuo Jiaxi 9p, Shi Yue 9p and Ke Jie 9p all entering the quarter finals. Kim Jiseok 9p got his revenge on Gu Li 9p after their 10th Chunlan Cup semifinal match.

Yo Seiki 7p continued to fly the flag strongly for the Kansai Kiin, defeating Korean youngster Lee Donghun 5p.

Korea will enter the quarter finals with some of its strongest pros.

Kang Dongyun 9p was too strong for the Korean amateur 5d An Jungki (who qualified through the preliminaries) and Wong Seongjin 9p snuffed out Taiwan’s hopes by defeating Lin Junyan 6p.

Over in the battle of the Parks, Park Younghun 9p emerged victorious over Park Junghwan 9p.

Three-player teams from China, Korea, Japan, and Chinese Taipei competed. The teams finished in the order just given. Representing Japan were Fujisawa Rina 2P, Xie Yimin 6P, and Kaneko Maki 1P. Results are given below.
(Round 1) China beat Japan 3-1; Korea beat Chinese Taipei 3-0. (Round 2) Japan beat Chinese Taipei 3-0; China beat Korea 2-1. (Round 3) Korea beat Japan 3-0; China beat Chinese Taipei 3-0. So Yokoku 9P accompanied the Japanese team as coach. A conversation he had with the top board for China, Yu Zhiying 5P, gives an idea of what goes into becoming a top player. As a member of the national team, Yu studies at the Chinese Qiyuan from 9 to 5, Monday to Friday. At night, she plays Net games, with her norm being 3.5 games a night. Even on days when she has official games, she still completes her norm. She said she plays about 1,700 games a year. So commented that Fujisawa and Xie are also studying hard. In an interview with the Chinese press, Fujisawa said that she studies eight to ten hours a day, at least six days a week. The other members of the Chinese team were Song Rongrui 5P and Rui Naiwei 9P. The Korean players were Choe Cheong 5P, Kim Hye-min 7P, and Pak Ji-yon 3P. Choe inflicted the sole loss suffered by China, defeating Yu on the top board. As of May, Choe was the top-ranked woman player in the world (#193 on the geocities site).

Yo Seiki wins Okage Cup: The O-kage (gratitude) Cup is sponsored by a group of tourism-related shops in the street leading to Ise Shrine. It is open to players 30 and under and so far has been won by Cho Riyu (2010), Anzai Nobuaki (2011 and 2012), and Ichiriki Ryo (2013 and 2014). This year, the main tournament (for the best 16) was held in Ise City on May 14 And 15. In the final, Yo Seiki 7P of the Kansai Ki-in (W) beat Ichiriki by resignation.

Hane senior wins 1,200 games: On May 21, Hane Yasumasa 9P became the sixth player at the Nihon Ki-in to reach the landmark of 1,200 wins. It took him 57 years one month (he will turn 71 on June 25). With 641 losses and 5 jigos, his winning percentage is 65.2. He won the Oza title in 1990. He is the father of Hane Naoki.

Go Spotting: What esports have to learn from go

While esports have becomes hugely popular in recent years, garnering large audiences, broadcast on ESPN and major sponsorships, they may 2015.06.07_esportsstill have something to learn from the ancient game of go. That’s the premise of “Go: The First Generation of Competitive Games,” an article published recently in “1337,” major e-sports trade magazine. “Despite similarities, go and esports are worlds apart in terms of perception,” writes Michael Cohen. “While go is intertwined with some national cultures, esports faces the stigmatization of video games as a whole.” Noting that go is “accepted by all generations as a legitimate game of mental strength and strategy, as well as a tool for teaching life values to children and adults alike,” Cohen suggests that go “may also be a predictor of what esports can hope to become throughout everyday life.” In an ironic turn, “it looks like they’re looking to go for an example for how to make the jump to legitimacy as a reputable pastime, compared to how we look to them for tips on marketing, sponsorship, and promotion,” says AGA VP of operations Andrew Jackson, who sent us the article.

The Power Report (I): Iyama takes 3-0 lead in Honinbo title match

by John Power, Japan Correspondent for the E-Journal2015.06.08_70honinbo3_2

Iyama takes 3-0 lead in Honinbo title match: In the 70th Honinbo title match, Yamashita Keigo is seeking to regain the title that he lost to Iyama Yuta in 2012. He is also seeking revenge for his loss to Iyama in this year’s Kisei title match. As defending champion, Iyama is hoping to maintain his quadruple crown; after losing two titles at the end of last year, he will be anxious to avoid any further reductions to his swag. Also, if he defends his title, it will be his fourth in a row, so he will draw near to qualifying for the title of Honorary Honinbo.

Just as in the Kisei title match, Iyama has made a great start, sweeping the first three games. In the Kisei, Yamashita staged a recovery, winning three games in a row himself. Will he be able to do it again?
The first game was played in the Fugetsuro pavilion in Shizuoka City on May 13 and 14. This was the hometown of Tokugawa Ieyasu, the warlord who founded the Tokugawa Shogunate, and the game was one of the events in the celebration of the 400th anniversary of Ieyasu’s death. The Fugetsuro is located on the estate of the 15th and last shogun, Tokugawa Yoshinobu. Yamashita drew black in the nigiri. He was doing fairly well in the fighting, but a couple of slightly dubious moves let Iyama into the game. Yamashita then made a misreading about a possible capturing race and so failed to play the best move. Although he was still ahead on the board, he couldn’t give the komi, so he resigned after 164 moves.

2015.06.08_70honinbo3_3The second game was played at the Shikimeien garden in Naha City, Okinawa on May 25 and 26. Fierce fighting started in the opening. In the middle game, Yamashita (white) made a fatal blunder and fell behind. Iyama wrapped up the game safely, and Yamashita resigned after 177 moves.

The third game was played at the Jozankei Resort Spa Mori no Uta (Song of the Forest) in Sapporo City, Hokkaido on June 3 and 4. In this game, there was no major fighting — when the first proper fight looked like breaking out, the players settled for a peaceful trade, and when another fight looked like starting, it again ended peacefully. In each case, it was Iyama (white) who made the decision to avoid a fight; it retrospect, it can be said that he was confident he had a lead and he denied Yamashita any chance to exert his strength. The latter resigned after 142 moves.

World Amateur Go Championship: Korea & Chinese Taipei Undefeated After 4 Rounds; US & Canada Both 3-1

Twelve-year-old Jyun-Fu Lai 7d of Chinese Taipei (right) and Korea’s Changhun Kim 6d were the only two undefeated players at the end of the2015.06.08_WAGC_Jyun-Fu-Lai second day of the 2015 World Amateur Go Championships (WAGC) in Bangkok, Thailand on June 8. Indonesia’s 12-year-old Rafif Fitrah 4d had notched a surprise victory over Ondrej Silt 6d (Czech Republic) in the only major upset of the first day of the WAGC on June 7, as both Rounds 1 and 2 concluded with few surprises. Danny Ko (US) is 3-1, defeating Germany, Israel and Indonesia and losing to Chinese Taipei in the second round. Canada’s Juyong Koh is also 3-1, beating Poland, Russia and and Colombia and losing to Korea in the 3rd round. Click here for latest results. The festivities kicked off on Saturday morning with a friendship event and the Annual General Meeting of the International Go Federation (IGF) was held that afternoon (click here for full report). Highlights of the reports included the uncertain future of the Sport Accord World Mind Games (SAWMG), which may move from an annual event to biennial, possibly restarting in 2016 in China. China is likely to again host the World Mind Sport Games, probably in Macau in 2016. China will also host next year’s WAGC, although the exact location is yet to be decided. Also reported was the release of the IGF Facebook page and YouTube channel. In other reports, Poland’s Koichiro Habu 4d missed a critical move that could have allowed him to snatch victory from Canadian Juyong Koh 7d, both playing for their first time at this event.
