Tang wins again in Samsung Cup

The 2019 Samsung Cup (the 23rd) was held at a Samsung training center in Taejon, Korea, from August 30 to September 6. It culminated in a best-of-three final in which Tang Weixing 9P of China beat his compatriot Yang Dingxin 9P 2-1. Apparently Tang had been in a bit of a slump recently, which explains why he was rated only no. 28 in China, but he has always done well in this tournament. After making his international debut by beating Lee Sedol 2-0 to win the 2013 Samsung Cup, he took second place in 2014 and 2017, and in-between won the 8th Ing Cup in 20126.

Japan had only three participants in this 64-player tournament: seeded players Iyama Yuta 9P and Kyo Kagen (Xu Jiayuan) 8P were joined by Cho Sonjin 9P, who won a seat in the senior division in the qualifying tournament. All were eliminated in the first round. Actually Iyama had a very good position against Tang Weixing, so much so that the Japanese team captain Ryu Shikun commented that the game was “hard to lose” for him. However, complicated fighting continued during byo-yomi and Iyama slipped up with move 171. He resigned after move 180. Actually Tang is known for his tenacity and has a good winning percentage in games in which AI programs adjudge him as being behind. Kyo lost to Li Qincheng of China. Li won the 3rd Globis Cup in 2016 and the 28th TV Asia Cup in the same year. The latter win earned him promotion from 2-dan to 9-dan, the biggest leap in rank any professional has made. Cho Sonjin lost to Tao Xinran 7P of China.

Kisei leagues

Kono wins S League

The final game of the S League, played on Sept. 26, was like a final, as the winner would win the league. Taking white, Kono Rin 9P (W) beat Kyo Kagen (Xu Jiayuan) by half a point. Kyo, on 3-1, had held the sole lead in the league going into this game, so this was a come-from-behind victory for Kono. Kyo didn’t even have the consolation of taking second place, which would have got him into the final knock-out section; as he was ranked no. 4, he was pipped by no. 3, Takao Shinji. Four players ended up on 3-2, but there are no play-offs in the Kisei leagues, so Kono, ranked no. 2, took first place.

The A League was won by Ichiriki Ryo 8P who scored seven wins in a row. Cho U was in second place on 4-3; both these players will move up to the S League. Three other players ended on 4-3: Yo Seiki 8P, who came third, Shida Tatsuya 8P, who came fourth, and Shibano Toramaru, then 8P, who will drop to the C League. This is one of Shibano’s rare failures recently. The B1 League was won by Yoda Norimoto 9P on 5-2 and the B2 League by Motoki Katsuya 7P on 6-1. Motoki beat Yoda in the play-off. The C League was won by Suzuki Shinji 7P on 5-0.

The challenger will now be decided by an irregular knock-out. The first game was played on October 9 between Suzuki and Motoki. Taking black, Suzuki won by 5.5 points; next he will play Ichiriki; the winner will play Takao; the winner will play Kono Rin in a “best-of-three” in which Kono starts off with one win. It is very hard for someone beside the winner of the S League to become the challenger. Results in the S League since my last report are given below.

(July 14) Kyo Kagen Gosei (W) beat Yamashita Keigo 9P by 5.5 points.

(August 6) Kyo Kagen (W) beat So Yokoku 9P by resig.

(August 22). Takao Shinji 9P (B) beat Yamashita by 6.5 points; Murakawa Daisuke Judan (W) beat Kono Rin 9P by resig.

(September 5) So Yokoku 9P (W) beat Takao Shinji by 2.5 points; Yamashita (W) beat Murakawa Daisuke Judan by resig.

Nakamura Sumire wins more official games

Ten-year-old Nakamura Sumire picked up her third official win in a game played on September 16. In a game in Preliminary C of the 59th Judan tournament, playing white, she beat Furuta Naoyoshi 4P by 1.5 points after 235 moves. The players are both members of the Kansai branch of the Nihon Ki-in, so the game was played at its headquarters. The game was not going well for her, but she pulled off an upset in the endgame. This is actually her first win in a tournament open to all professionals and her first experience of a three-hour time allowance, which is the mainstream for pro tournaments. On September 30, Sumire played her first game in the main section of the 23rd Women’s Kisei tournament; as detailed in my report of August 22, she set a record by becoming the youngest player to reach the main section of a tournament. The game was played in the Ryusei Studio in the basement of the Nihon Ki-in in Ichigaya in Tokyo. She faced a tough opponent in Mannami Nao 4P, who until recently held a women’s title, the 3rd Senko Cup. Sumire has an aggressive style; she attacked early and seized the initiative, getting a promising game. However, her momentum led her to make an overplay that let Mannami counterattack and stage an upset. Sumire resigned after 227 moves.

On October 2, Sumire played a game in Round One of Preliminary C of the 76th Honinbo tournament. Taking white against Yamamoto Kentaro 5P, she won by resignation after 232 moves. From here, nine successive wins will give Sumire a seat in the league that starts in autumn 2020. Sumire’s official record is now 4-2, which is not only eminently respectable but is also evidence that her selection under the new system was not premature.

Sumire is quite possibly the most popular Nihon Ki-in player just now, so she is often invited to go events. She played an exhibition game at the 9th Hankyu Railway Go Festival in Osaka for Enjoying the Cool of the Evening, held on August 14 & 15. A game pitting Sumire against Hane Ayaka 1P, the daughter of Hane Naoki who also became a professional this year, was one of the main attractions. Taking white, she won by resignation after 150 moves. On move 24, she played an AI innovation, which impressed the commentator on the game, Kobayashi Satoru 9P.

Sumire played another exhibition game at a festival, held on August 25, celebrating the 40th anniversary of the founding of the Nihon Ki-in Hiroshima Prefecture Headquarters. Taking white, she played her first game with Fujisawa Rina, holder of four women’s titles. Sumire went on the attack in the middle game and at one stage was doing quite well–an AI program rated her winning chances at 85%. However, she made a bad threat in a ko fight, so the tide turned against her. She resigned after 187 moves.

Finally, Sumire played two games in a preliminary round for Kansai women players of the 14th Hiroshima Aluminum Cup Young Carp Tournament, an unofficial tournament. In the first round, she played another game with Hane Ayaka (W), which the latter lost on time. In the next round, she lost by resignation to Miyamoto Chiharu 1P (W)
