Sumire extends winning streak, sets new record in promotion to 2-dan: Nakamura Sumire is going from strength to strength: she extended her winning streak to ten games and with the last of these wins, in a game played in the morning on March 15, secured promotion to 2-dan (effective as of the following day). At 12 years zero months of age, she broke a Nihon Ki-in record that had stood for 52 years. It was set by Cho Chikun, who made 2-dan when he was 12 years three months old. She also pushed Iyama Yuta, who became 2-dan at 13 years three months, into third place. On top of that, she took sole first place in the successive-wins list; it’s possible that she is the first woman player to top this list, but I could be wrong. Unfortunately, her streak came to an end in the afternoon of the same day. Sumire commented that she was happy to have made 2-dan while still (barely) an elementary-school pupil (she starts middle school in April). Just for the record, of the 13 Nihon Ki-in pros who debuted in April 2019, Sumire was the fourth to be promoted and the first of the eight female players in this group. Later in March, she also won a special tournament for teenagers (see preceding article). More details are given in the list of results since my last report below.
(March 1). Sumire (W) beat Tahara Yasufumi 7P (28th Agon Kiriyama Cup, Prelim. C). This win was a one-day-early birthday present to herself.
(March 10) Sumire (B) beat Tamura Chiaki 3P by resig. (preliminary, 6th Senko Cup).
(March 11) Sumire (W) beat Tajima Shingo 6P by half a point (First Tournament, Kisei tournament; incidentally, Tajima is a disciple of her father’s).
(March 15) In the morning, Sumire (B) beat Matsubara Taisei 6P by resig. (Prelim. B, Agon Kiriyama Cup). In the afternoon, she lost to Koyama Kuya 4P (W) by resig. in the same tournament. 
(March 18) Sumire (W) beat O Keii 2P by resig. in the 8th Women’s Hollyhock Cup prelim. and qualified for the main tournament.
(March 29) Sumire (B) beat Rafif Shidqi Fitlah 1P by resig. (Prelim. C, 47th Gosei tournament). This was her final game as an elementary-school pupil; her record this year is 13-2, which is not a bad first quarter, and her cumulative record to date is 51 wins to 26 losses. Sumire commented: “It was a difficult game, but at no stage was it bad for me.” Asked about her record, she responded: “It’s nice that I’ve won more games than I expected.” (Fitlah 1P of Indonesia made his debut as a professional in April 2020. He was born on July 12, 2002.)

Note: There was a lot of speculation about when Sumire’s promotion would come, but it was not easy to calculate, as not all games are counted in the list of cumulative wins. Her actual record when she got promoted was 49 wins, 25 losses, but only 30 of the wins counted for promotion. (Eligible domestic tournaments are the top seven open titles, King of the New Stars, Ryusei, Hiroshima Aluminum Cup, Agon Kiriyama Cup, Gratitude Cup, and SGW Golden Mean. Notably missing are women’s titles and the NHK Cup. International tournaments include: Samsung, LG, Bailing, MLily (but not the preliminary tournaments for these four), Nong Shim, Chunlan, Globis, World Go Championship, Xin-Ao, Tianfu Cup (previous two held only once each so far), and National Champion Mountain Range Cup. Notably missing are the Ing Cup, because of unorthodox rules, such as buying extra time with stones, and international women’s titles. (An additional reason for confusion is that tournaments sometimes change status, being made official. The best—or worst, depending on your point of view—example is the Hiroshima Aluminum Cup. Xie Yimin won the first cup, but she missed out on a place in go history as the first woman to win an official tournament open to both males and females because it did not become an official tournament until the sixth term.
