Sumire v. Iyama at New Ryusei

Sumire suffers setbacks but recovers
   As reported on June 4, Nakamura Sumire saw her winning streak come to an end and in fact suffered successive losses to two 9-dans. Although she won what was her third successive game against a 9-dan, she then lost four games in a row, the worst losing streak of her career so far. However, she is now balancing losses with wins, including her first win in an international tournament against a formidable opponent.

(June 3) Sumire (W) beat Nakane Naoyuki 9p by 1.5 points Prelim. B, 60th Judan tournament).
(June 4) Sumire beat Iwasaki Seito (2 stones) by 4. This was an unofficial game. Iwasaki is blind in his right eye and has 0.01 vision in his left eye. With the cooperation of the Nihon Ki-in, he has become an insei. He started out in April in D Class, but quickly moved up to C Class. He attends a school for the blind, and, like Sumire, is in the first year of middle school. He plays on a board, called “aigo,” adapted for use by players with vision disabilities. A 2-hour commentary (in Japanese) on the game can be found here.

(June 10) Sumire lost to Takeshita Ryoya 1p (Prelim. B, 47th Gosei).
(June 15) Sumire (W) lost to Nyu Eiko 3p by 6.5 points (semifinal, 8th Hollyhock Cup?see article above). Reaching the final four is Sumire’s best result in a tournament so far. 
(July 1) Sumire (B) lost to Shuto Shun 8p by 1.5 (46th Kisei, C League).
(July 5) Sumire (W) lost to Koyama Terumi 6p by 3.5 (Round 2, main tournament, 40th Women’s Honinbo.) This was her fourth loss in a row.
(July 8) Sumire (W) beat Ueno Risa 1p by resig. (Round 1, main tournament, 6th Senko Cup). This was her first win in an official game for five weeks. 
(July 15). Sumire (B) beat Muramoto Wataru 3p by resig. (Prelim. A, 60th Judan. This game was played at the Kansai headquarters of the Nihon Ki-in.)
(July 18) Sumire (W) beat Kim Jaeyoung 6p (Korea) by half a point. (Sumire was given a sponsor’s wild-card seed in the 4th Wu Qingyuan [Go Seigen] Cup; see report above. Kim won this tournament in its first year, so this is an excellent result for Sumire and her first international win.)
(July 19) Sumire (W) lost to Zhou Hongyu 6p (China) by resig. (Round 2 of tournament above.)
(July 22) Sumire (B) beat Endo Yoshifumi 8p by 2.5 (Prelim. C, 70th Oza.)
(July 29) Sumire (W) lost to Iyama Yuta Kisei in round one of the New Ryusei tournament. This is an unofficial tournament, presumably because of its very short time allowance. Players start with one minute and get an extra five seconds every time they play a move (a system known as Fischer time, after its inventor Bobby Fischer). There are 32 participants in a knock-out; Sumire was chosen as one of two special seeds. After the game, she commented that she was “cut to pieces.” (The above information comes from the Net. The Nihon Ki-in is withholding news of the result until the game is televised on August 28.)
(August 2) Sumire beat Antti Tormanen 1p (Prelim. C, Tengen) (details not yet available).   
Sumire still has the second-most wins of all Nihon Ki-in pros but no longer the best winning percentage; see below. However, I have a problem. Go Weekly (and the Nihon Ki-in HP) gave her score as 29-8 as of July 16, compared to 26-8 as of July 9, but I can find only one result, listed above, for that week. A Net site that tracks her results didn’t have the two “missing” games either.

Most wins (as of July 31)
1. Ueno Asami, Women’s Kisei: 35-13
2. Nakamura Sumire: 31-10 (75.6%) (note that the last two games given above are not included)
3. Fukuoka Kotaro 2p: 27-4 (86.6%). Fukuoka was on a winning streak that stopped at 13, so he is level with Sumire for the best winning streak so far this year.
4. Fujisawa Rina: 23-10; Motoki Katsuya 8p: 23-11; Kyo Kagen Judan: 23-12; Nyu Eiko 3p: 23-28. Tsuneishi Takashi 4p: 22-2 (at 91.6%, the best winning percentage); Ichiriki Ryo Tengen: 22-5 (his 12-game winning streak stopped a few weeks earlier); Seki Kotaro 4p: 22-7.
   At present, there are four women players in the top ten.

Best winning streak
11: Tsuneishi Takashi
9: Otake Yu. Sumire’s father, Shinya 9P, briefly entered the list with 5-in-a-row, but was unable to keep his streak going.
