Top pro titles: A primer

Saturday August 21, 2021

73rd Honinbo title match (2018), Iyama Yuta 9p v. Yamashita Keigo 9p.

Most western go players are probably familiar with the top professional titles in Japan, but less so with those in China and Korea. Here’s a quick primer.  

The top three tournaments in Japan are the Kisei, Meijin, and Honinbo, all currently held by Iyama Yuta 9p, who’s been dominant for some years. The Honinbo is the oldest pro title in the world, first held in 1941: the current occurrence of the contest for that title is the 77th. The other four big Japanese titles are Gosei, Oza, Judan, and Tengen.  They also have been running for many years, and in terms of a long, stable tournament history, Japan is the best in the world.

The oldest title in Korea is the Myeongin, equivalent to the Japanese Meijin and to the Chinese Mingren. Currently being contested for the 44th time, it was discontinued for several years, but is being actively fought for this year. The last previous winner was Lee Sedol 9p in 2016. The final match this year is a five-game contest between Shin Jinseo 9p, who holds several other Korean titles and is currently considered number one in Korea, and Byun Sangil 9p. Shin Jinseo also holds several other Korean national titles and the Asian TV Cup. He defeated Ding Hao 6p of China for the latter title.

The oldest title in China is the Tianyuan, which was contested for the thirty-fifth time this year: Gu Zihao 9p defeated the previous holder of the title, Yang Dingxin 9p, by a score of 2-1. The next oldest Chinese national title is the Mingren, which was won most recently by Mi Yuting 9p. Ke Jie 9p, who has won more international titles than any other player currently active, has not done as well at the national level, but he does hold four national titles currently, including the Changqi Cup, which is one of the more prestigious titles, and the Qisheng. As a result he is considered number one in China.

There are also pro titles in Taiwan, of course, though the Taiwanese pros have not had much success at the international level. This is partly because the best Taiwanese players usually moved to Japan to play very early in their careers. Some of these have done quite well in Japan, such as the well-known Cho U 9p, Rin Kaiho 9p, and O Rissei 9p, all of whom have held some of the top Japanese titles. In fact, O Rissei 9p recently won the 1st Shinan International Senior Baduk Cup, playing for Taiwan and defeating such famous older players as Japan’s Kobayshi Koichi 9p and China’s Yu Bin 9p as well as Seo Bongsoo 9p of Korea. Both Cho U and O Rissei won the Japanese Kisei title three times in a row when they were playing as members of the Nihon Ki-in. O Meien is also a native of Taiwan who joined the Nihon Ki-in and won the Honinbo title in 2000 and 2001.

The Power Report: Kisei S League; Iyama plays in top Chinese league

Monday August 16, 2021

by John Power, Japan correspondent for the E-Journal

Kisei S League
   Two players were undefeated in the 46th Kisei S League on 3-0, so their clash on July 26 was the key game of the league to date. Ichiriki Ryo beat Yo Seiki, so the former took the sole lead. On 2-1, Murakawa Daisuke is still in the running if Ichiriki falters and he wins his remaining two games, as he is ranked above Ichiriki and there are no play-offs within the league. For the same
reason, Yo, though on 3-1, is out of the running, but he could come second and make the knock-out tournament to decide the challenger. Takao Shinji is also in the running for second place. Results since my last report follow.

(May 31) Yo Seiki 8p (B) beat Takao Shinji 9p by resig.
(June 10) Yo (W) beat Kono Rin 9p by resig.
(June 17). Ichiriki Ryo Tengen (W) beat Murakawa Daisuke 9p by resig.; Takao (B) beat Yamashita Keigo 9p by 3.5.
(July 15) Takao (W) beat Kono by resig.
(July 26) Ichiriki (W) beat Yo Seiki by resig.

   In the A League, Onishi Ryuhei 7p and Shibano Toramaru Oza share the lead on 4-2. In the B1 League, Shida Tatsuya 7p has the sole lead with 5-1. In the B2 League, So Yokoku 9p and Son Makoto 7p share the lead on 5-1. In the C League, four players have started with three straight wins: Yamashiro Hiroshi 9p, Numadate Sakiya 7p, Otake Yu 5p, and Yuki Satoshi 9p. Scores of the female players in this league are: Fujisawa Rina, Women’s Honinbo, 1-2; Xie Yimin 6p 1-1; Nakamura Sumire 2p 0-2.

Iyama plays in top Chinese league
   The Chinese A Class League, a large-scale team tournament, probably represents the top level of go competition in the world. Unfortunately, information about it is hard to come by for people who do not know Chinese, but the ejournal published an excellent article by Yuan Zhou on July 20. This year Japan’s top player, Iyama Yuta, is participating for the first time, and he played his first game on June 12. This happened to be the day after he suffered his third
 successive loss in the Honinbo title match. Iyama is a member of the Zhejiang Ticai team, and his opponent was Xie Ke, one of China’s top players, who represented the Supoer Hangzhou team. Taking black, Iyama scored a good win, keeping the initiative throughout the game. This game was actually in the 10th round of the league; so far his team has three wins, four losses, and three draws, and is running 10th out of 16 teams. By the way, earlier in the year, Shiban
o Toramaru and Ichiriki Ryo both played a game in this league but lost.

The Power Report: Iyama defends Honinbo title, matches Cho’s record; 4th Wu Qingyuan Cup

Monday August 9, 2021

by John Power, Japan correspondent for the E-Journal

Iyama Yuta celebrates 10th consecutive Honinbo win
Yu Zhiying 7p (China)

Iyama defends Honinbo title, matches Cho’s record
   As of our previous report (June 4), the 76th Honinbo title match between Iyama Yuta, also known as Honinbo Monyu, and Shibano Toramaru Oza was tied 1-1. When the defending champion won the first game, Shibano fans would have been worried that this match might follow the path of last year’s Honinbo and Meijin title matches, both of which were one-sided, ending in 4-1 victories for Iyama. However, Shibano roared back in the second game, crushing Iyama in 96 moves.
   The third game was played at the Hotel Agora Osaka Moriguchi in Moriguchi City, Osaka Prefecture, on June 1 and 2. Taking black, the challenger, Shibano Toramaru Oza won by resignation after 149 moves. In the opening, Shibano staked out a large moyo. Iyama was confident he could erase it, but a large group of his inside the moyo got into trouble. When he was unable to save it, he had to resign. This was another convincing win for Shibano, who incidentally took a lead over Iyama for the first time in a best-of-seven.
   The fourth game was held at the Art Hotel Kokura New Tagawa on June 10 and 11. This game also featured aggressive fighting and once again Shibano came out on top, capturing a large group. Iyama (black) resigned after just 124 moves. O Meien 9P, the newspaper commentator, said: “I felt Shibano’s reading was awesome. Iyama can’t often have been outread like this. It was a convincing win for Shibano.” This was the first time Iyama had fallen behind 1-3 in the Honinbo title.
   Game Five was the first kadoban (a game that can lose a series) for Iyama.It was played at the Matsumoto Hotel Kagetsu in Matsumoto City, Nagano Prefecture, on June 21 and 22. The game started peacefully. In the middle game, a kind of trade took place, with Iyama (white) capturing a group in exchange for letting Shibano put a large white group into ko. The game was dominated by this ko, which went on for 90 moves. In the end, Shibano captured the group, but was forced to let White take a fair bit of profit with his ko threat. Shibano resigned after White 218. Yamashita Keigo, the newspaper commentator, said: “There’s no move that I can clearly label as bad among the Honinbo’s moves.” This convincing win by Iyama changed the flow of the match.
   Game Six was played at the Todaya hotel in Toba City, Mie Prefecture, on June 29 and 30. Iyama (B) took a small lead on the first day. In the middle game, the lead became confused, but Iyama was saved by a mistake made by Shibano, who resigned after move 153. Iyama saved his second kadoban and tied the match. He now seemed to have better momentum than the challenger.
   The final game was held at the Tokiwa Hotel, Kofu City, Yamanashi Prefecture,  on July 6 and 7. Iyama drew white in the nigiri. He convincingly outplayed Shibano and won by resignation after 180 moves. He made an excellent recovery after losing three games in a row by returning the courtesy to his opponent. Having won the title ten years in a row, he matched Cho Chikun’s record. Shibano missed out on his chance to become the youngest tournament Honinbo. First prize is 28 million yen (about $254,500).

4th Wu Qingyuan Cup
   The opening rounds of the 4th Wu Qingyuan (Go Seigen) Cup World Women’s Go Tournament were held on the Net on July 18 to 20 with 16 players competing. Of these, three Chinese players and one Korean survived to make the semifinals. For Japanese fans, the highlight of the tournament was Nakamura Sumire’s scoring her first international win. The best performer for Japan was Fujisawa Rina, who picked up two wins. The dates of the semifinals and final have not yet been decided. Below are the results so far.

Round 1 (July 18). Fang 4p (China) (B) beat Stephanie Yin 1p (US) by resig.; Oh Yujin 7p (Korea) (W) beat Natalia Kovaleva 5d (Russia) by resig.; Cho Seunga 3p (Korea) (W) beat Hei Jiajia 7p (Ch. Taipei) by resig.; Li Xinyi 3p (China) (W) beat Manuela Marz 3d (Germany) by resig.; Lu Minquan 6p (China) (B) beat Xie Yimin 6p (Japan) by 1.5; Ueno Asami 4p (Japan) (W) beat Luo Yuhua 3p (Ch. Taipei) by 0.5; Suzuki Ayumi 7p (Japan) (W) beat Feng Yun 9p (US) by resig.; Nakamura Sumire 2p (Japan) (W) beat Kim Jaeyoung 6p (Korea) by 0.5.
Round 2 (July 19). Fujisawa Rina 5p (W) beat Li by 2.5; Yu Zhiying 7p (China) (W) beat Ueno by resig.; Wang Chenxing 5p (China) (W) beat Suzuki by resig.; Zhou Hongyu 6p (China) (W) beat Nakamura by resig.; Choi Jeong 9p (Korea) (W) beat Lu by resig.; Fang (B) beat Rui Naiwei 9p (China) by resig.; Cho (B) beat Tang 4p (China) by 1.5; Oh (W) beat Li He 5p (China) by 2.5.
Quarterfinals (July 20) Yu (W) beat Fujisawa by resig.; Fang (W) beat Cho by resig.; Wang (W) beat Oh by resig.; Choi (B) beat Zhou by resig.
Semifinal pairings (date undecided). Wang v. Yu; Choi v. Fang

Inside the Chinese A League

Tuesday July 20, 2021

by Yuan Zhou    

There’s a very important professional go event that western go players probably don’t know much about. Known in English as “The Chinese A League” and started in 1999, the annual format changes, but currently it consists of sixteen teams, each of which is associated with a particular city that is the home of the corporate sponsor of the team. Divided into two groups of eight teams each, they play each other twice in a round robin event that is extremely popular among Chinese go fans. The teams contain six pro players each, and teams in the stronger “A” league (there is also a “B” league) are allowed to add one foreign pro to their team (this is expensive, of course). Each encounter involves four games between the two teams so only four of the six play each time. Three of the games involve relatively long basic times, two hours each, but one game is fast play, one minute per move. This latter difference is to accommodate having one of the games in each meet shown on TV. After the round robin season, the two teams with the best records have a play-off to determine the ultimate winner, and the two with the worst records have a play-off to see which gets eliminated from the League.

Ke Jie 9p of China

This event means that Chinese pros are regularly involved in very high-level games during the year, which is made even more valuable by having top foreign pros involved. For example, in the most recent running of this event, the foreign players included Shin Jinseo 9p of Korea (known as “AI Shin” because of his devotion to studying the AI strategies and considered by many to be Number One in Korea), Shin Minjun 9p who is challenging for first place in Korea, Park Junghwan 9p of Korea, as well as Lee Donghoon 9p and Kim Jiseok 9p of Korea, and also Iyama Yuta 9p who holds the top titles in Japan, Ichiriki Ryo 9p of Japan who is challenging Iyama these days, and Shibano Toramaru 9p.

This extraordinary amount of high-level competition, combined with exclusive access to the best of the AI programs, Fine Arts, is probably the main reason Chinese pros are currently dominating the international go scene, winning most of the titles. If you look at the list of title holders on the go news web site mentioned below, you will see the overwhelming number are Chinese.

Because of the high level of expertise and the decent basic playing time, these Chinese A League games are some of the best in the world every year. I have provided commentaries of several of them over the years in the E-Journal. You can access reports of these games on the go news site, where some of the game records can also be downloaded.

Chinese Weiqi Association publishes Chinese-English Dictionary of Weiqi Terms

Friday February 26, 2021

Bob Bacon reports that earlier this month, several Chinese news organizations such as Xinhua Net and SINA English reported that the People’s Publishing House and the Chinese Weiqi Association have jointly published the Chinese-English Dictionary of Weiqi Terms. With 643 definitions over six chapters, the dictionary took seven years to compile and was first used during the World Weiqi Summit in Rizhao, China in 2019. “‘As a spiritual symbol of Chinese culture, as well as an internationally recognized public product with positive effects, Weiqi has special requirements in terms of language. It has its own way of thinking, terminology paradigm and communication mode. An important aspect of the Chinese Weiqi Association’s goal is to promote a unified and standardized Weiqi language,’ said Lin Jianchao, chairman of Chinese Weiqi Association.” Informal sources indicate that while the resource is not yet available publicly, it will be made available soon.
