Iyama loses Oza, keeps Tengen
Iyama Yuta started the year with five titles, but ended it with only three. Like the previous year, he lost two titles, but he remains the number one player even in his 30s.
The fourth game of the 67th Oza title match was played at the Ginbaso inn in Nishiura Hot Spring in Gamagori City, Aichi Prefecture, on November 29. Taking white, Shibano Toramaru Meijin (left) beat Iyama Yuta (right) by half a point. This gave him a lead of 3-1, so he took the title. The first half of the game focused on a struggle by Black to secure life for a group inside White’s sphere of influence. Shibano’s attack was more severe than Iyama had expected: he seemed to read more deeply in this fight. He discarded a group while capturing the tail of Black’s group in sente, so he took the lead here. However, he made a slip later that let Black catch up. The game was decided by the final half-point ko: Black didn’t have enough threats to win it.
This is Shibano’s second title, so he has clearly established himself as Japan’s number two. Shibano: “There were many difficult positions and tough fights [in the series]. I was lucky to win.” Iyama: “Shibano has developed into a player who can represent Japan. I expect even bigger things from him. [As for being reduced to three titles,] I would like to commend myself for having been able to secure good results over a long period. Going by my recent form, this loss can’t be helped.”
Iyama came to the fourth game of the 45th Tengen title match in the same position as in the Oza: down 1-2 to a youthful challenger. Kyo Kagen (aged 21) was also the player who put an end to his second grand slam when he beat Iyama 3-0 in the 43rd Gosei title. The 4th game was played at the Hotel New Awaji, a hot spring hotel in Sumoto City, Hyogo Prefecture, on December 9. Taking black, Iyama forced a resignation after 177 moves. This game started with the large avalanche joseki, which was the king of the josekis in the 70s. Kyo got a bad result, with his outside influence not being a match for Black’s territory. Kyo narrowed the gap with some good play later, but Iyama kept the initiative and scored a comfortable win.
The fifth game was played at the Tokushima Grandvrio Hotel in Tokushima City, Tokushima Prefecture, on December 18. Kyo drew black in the nigiri. The game was a spectacular one: Kyo fell behind, so he started a fight to the death between two large groups; Iyama outplayed him, saving his group and securing the lead. The game ended in a large capturing race that Kyo lost, so he resigned after move 234.
Incidentally, ever since he won the Honinbo title in 2012, Iyama has always held at least three titles.
Nakamura Sumire beats 9-dan, is top new 1-dan

Ten-year-old Sumire is continuing to enjoy good results, scoring a win against a 9-dan, but her winning streak against male professionals has come to an end. Details of her games since my previous report are given below, but first let’s look at an honor she earned off the go board. A meeting of go-linked media representatives to choose the 37th Japan Igo Journalists Club Prize was held at the Nihon Ki-in in Tokyo on November 26, and, not surprisingly, the unanimous choice was Sumire. There were other landmark performances by young players—for example, Shibano Toramaru’s becoming the first teenaged Meijin and Ueno Asami’s becoming the first woman to reach the final of a tournament open to male and female players—but they did not match the impact Sumire had on both the go world and the general public. The citation read: “[Sumire] attracted attention as the youngest professional in history and has had outstanding results since becoming 1-dan. Her success is worthy of the Special Promotion System.”
In a game in the second round of the 45th Kisei preliminary tournament, played at the Nagoya branch of the Nihon Ki-in on November 28, Sumire (W) beat Baba Shigeru 9P (aged 71) by resignation after 260 moves. This took her official record to 13-5 and was her seventh win in a row against male players. After the game, she said: “I thought it was bad for me.” Baba commented: “She played tenaciously at the end. I think the lead changed hands two or three times in the endgame.” Three more wins in the Kisei will secure a seat in the C League, which would be quite a coup.
The sponsors of the 2nd Wu Qingyuan (Go Seigen) tournament arranged as a side event a best-of-three match between Sumire and Wu Yiming 2P of China. It had the grand title of the Japan-China Women Super New Stars Invitational Best-of-Three. The result was a 2-0 win for Wu, who had just turned 13. This victory won her a seeded place in the 3rd Cup next year. The games were played in the Wu Qingyuan Hall in Fuzhou City, which is the hometown of Wu Qingyuan, in Fujian Province on December 2 and 3. Taking black, Wu won the first game by resignation; in the second game, Wu (W) won by 2.5 points. Sumire’s parents accompanied her on the trip, and her father, Shinya 9P, commented: “Overall, she showed all her strength. This result reflects her present level.” Sumire again attracted a lot of attention and a photo of her was used for the cover of the weiqi magazine Weiqi Universe. Incidentally, her opponent Wu became 1-dan last year in the Chinese qualifying tournament; she was one of 14 women who were successful. This year another 12 women made it, but Wu is still the youngest female player in China. (These games are not counted by the Nihon Ki-in as official games; just guessing, but the reason might be that, as invitational games, they are not in a tournament open to other women players.)
On December 9, Sumire played Hane Ayaka 1P in the preliminary tournament for the 7th Aizu Central Hospital Women’s Hollyhock Cup. Taking black, Sumire won by 7.5 points after 290 moves. Her record against Hane, daughter of Hane Naoki Gosei, is now 2-0. She needs two more wins to get a seat in the main tournament. The game was played at the Nagoya Nihon Ki-in.
On the 12th, Sumire played Komatsu Daiki 3P in Preliminary B of the 59th Judan tournament. Taking black, she lost by resignation after 202 moves. This put an end to her winning streak against male players.
On December 16, Sumire played Nyu Eiko 2P in one of the finals of the preliminary round of the 45th King of the New Stars tournament. Nyu (W) won by 6.5 points. The game was played at the Nihon Ki-in in Tokyo.
On December 19, Sumire played Takatsu Masaaki 1P in the preliminary tournament of the 45th Kisei tournament. Taking white, Sumire won by resignation after 294 moves.
On December 23, Sumire played Tafu Kae 3-dan of the Kansai Ki-on in the preliminary round of the 5th Senko Cup. Taking white, she won by resignation after 224 moves. The game was played at the Kansai Ki-in. Two more wins will secure her a seat in the main tournament, in which the top 16 women players compete.
Sumire’s last official game of the year was played at the Kansai headquarters of the Nihon Ki-in in preliminary C of the 46th Meijin tournament on December 26. Her opponent was Yamada Wakio 7P, younger brother of Yamada Shiho 7P, whom she beat in October (their younger brother is Yamada Kimio 9P). Taking white, she secured a resignation after 144 moves. Actually her opponent had the lead, but, according to Ishii Kunio 9P, “as if entranced, he played a move he shouldn’t have,” so she pulled off an upset. This result was reported on at least 11 different news sites on the Net,
Sumire’s record for the first “year” (actually nine months) of her career was 17-7, a winning record of 70.8%. These stats were the best of the 13 new 1-dans who debuted in 2019. That’s a remarkable performance, and no one can claim to have foreseen it. In an interview after the award ceremony for the above-mentioned press prize, held on December 17, Sumire commented: “I won more than I expected, so I’m happy Becoming a pro and being able to travel to China and Taiwan for games was great. I’ll do my best to get stronger next year.” Her first 2020 game is on January 13. She plans to attend a summer camp in Japan at the end of December and to make a study trip to Korea in the new year.
Choi wins 2nd Wu Qingyuan Cup
The semifinals and finals of the 2nd Wu Qingyuan Cup World Women’s Championship were held in the Wu Qingyuan Hall in Fuzhou City in Fujian Province. Fuzhou was the birthplace of Wu Qingyuan (Go Seigen). As reported in the June 23 issue of this journal, three Chinese and one Korean made the best four. In the semifinals, held on November 30, Choi Jeong 9P (Korea) beat Li He 5P and Wang Chenxing 5P beat Rui Naiwei 9P. The latter was apparently an epic game. The 28-year-old Wang became well known when she won the 4th Bingsheng Cup in 2013. She married Liu Xing 7P and after having a baby in 2017, became famous for taking it with her around the country as she played in the women’s team league. The 55-year-old Rui, who has won 13 women’s titles, seemed to have a sure win, but Wang fought back, securing a four-approach-move ko, usually quite disadvantageous (she had to add four stones before it became an immediate ko), for a group of hers that had been captured. Somehow she pulled off an upset. Rui was bitterly disappointed: as a disciple of Wu’s, she would have loved to win this tournament.
The final is a best-of-three. On December 2, Choi (W) beat Chen by resig. and on the 3rd, Choi (B) again won by resig., so she took the title 2-0. First prize is worth 500,000 yuan (about $71,500). Choi has also won the Bingsheng title four times. She confirmed her standing as the world’s number one woman player.
