The Power Report: Sumire’s progress; Takemiya wins 1200 games; Yoshida Mika first woman player to win 700 games

Friday March 5, 2021

Takemiya wins 1200 games
On Jan. 14, Takemiya Masaki 9P (W) beat Hara Sachiko 4P by resig. in a game in the First Tournament (= preliminary) of the 46th Kisei tournament. This made him the 10th member of the Nihon Ki-in to reach the mark of 1,200 wins. He has 764 losses and two jigo, for a winning percentage of 61%, which is 10th best. It took him 55 years nine months, which is ninth quickest. He is also the ninth oldest (he turned 70 on NY’s day).

Sumire’s progress
As of January 1, Nakamura Sumire 1P switched to the Tokyo branch of the Nihon Ki-in. She has made a superb start there with seven wins to just one loss (as of Feb. 18), as detailed below. She actually started off her go year by being featured in the special go program presented by NHK to celebrate the new year (telecast on the 3rd). Taking black with no komi, she played a game with Shibano Toramaru Oza. Before the game, the program delved into the background of the players, showing photographs of them when younger. That was followed by an entertaining “talk show” between Sumire and Hirata Tomoya 7P. The latter shared commentating duties on the game with Kobayashi Satoru and Ueno Asami. In an aggressive game featuring tenukis in the opening and trades in the middle game, Sumire held her own, but Shibano ratcheted up the pressure by complicating the game and forced a resignation after move 168. In the end, she may have been outplayed by Shibano, but the commentators praised her fighting spirit.
(Jan. 7) Sumire played two games in the 32nd Woman’s Meijin Prelim. A. In the morning, taking white, she beat Tsukuda Akiko 5P by resig. to score her fourth win in a row in this tournament. One more win would give her a place in the league. In the afternoon, Ueno Asami, Senko Cup-holder, (B) beat Sumire by 9.5 points.
(Jan. 18). Sumire (B) beat Sakakibara Fumiko 6P by resig. (8th Women’s Hollyhock prelim.)
(Jan. 21) Sumire (W) beat Minematsu Masaki 6P by resig. (Prelim. C, 60th Judan).
(Jan. 25) Sumire (W) beat Iwata Saeka 1P by 1.5 points (prelim., 40th Women’s Honinbo prelim.).
(Feb. 4) Sumire (W) beat Ha Yon-il 6P by 13.5. (First Tournament, 46th Kisei).
(Feb. 11) Sumire (W) beat Tatsumi Akane 3P by 5.5 (Women’s Hollyhock prelim.).
(Feb. 18) Sumire (W) beat Takao Mari 1P by half a point (Women’s Honinbo).
Sumire now has a winning streak of six. Go Weeklytracks players with winning streaks; when hers reached five, her name was included. With six, she is equal third among the twelve players enjoying winning streaks.

Yoshida Mika first woman player to win 700 games
On February 10, in the final game of the 40th Women’s Honinbo preliminary tournament, Yoshida Mika 8P of the Kansai Ki-in (B) beat Mizuno Hiromi 5P, also of the Kansai Ki-in, by resignation. This was her 700th win in official games. She is the first female Japanese pro to reach this mark. Her record is 700 wins to 550 losses and one jigo (tied game). Yoshida turned 50 on Feb. 12.

The Power Report: Kyo to challenge for Judan title; Ichiriki shares lead in Honinbo League

Wednesday March 3, 2021

by John Power, Japan correspondent for the E-Journal

Kyo to challenge for Judan title

Kyo Kagen

The play-off to decide the challenger for the 59th Judan title, held by Shibano Toramaru, was held at the Nihon Ki-in in Tokyo on Jan. 28. Taking black, Kyo Kagen (Xu Jiayuan) 8P beat Yo Seiki (Yu Chengqi) 8P by resig. after 147 moves. This will be Kyo’s chance to take revenge for his loss in last year’s Oza title match. The match starts on March 2.

Incidentally, this tournament acquired an extra sponsor as of January 1: Daiwa House Manufacturing, based in Osaka. (The main sponsor since the tournament was founded has been the Sankei Newspaper.) The official name of the tournament now is: Daiwa House Cup Judan Tournament. There has been no increase in the prize money of 7,000,000 yen so far (the reason may be that the new sponsor joined halfway through the current term).

Ichiriki shares lead in Honinbo League

As the sole undefeated player, Ichiriki Ryo Tengen held the lead after the midway round of the 76th Honinbo League, but a fifth-round setback suffered at the hands of Shibano Toramaru Oza has thrown the lead into a three-way tie, with Ichiriki, Shibano, and Hane Naoki all on 4-1. Results this year:

(Jan. 7) Kyo Kagen 8P (B) beat Ko Iso 8P by resig.
(Jan. 14) Shibano (B) beat Tsuruyama Atsushi 8P by resig.
(Feb. 4) Shibano (W) beat Ichiriki by resig.; Ko Iso (W) beat Sada Atsushi 7P by resig.
(Feb. 11) Hane (W) beat Tsuruyama by resig.
(Feb. 18) Onishi Ryuhei 7P (B) beat Kyo Kagen by resig.

ICYMI: Kim Eunji 2p’s AI cheating incident; Playing Go with Darwin; Remembering John Conway

Monday March 1, 2021

Kim Eunji 2p’s AI cheating incident
Thirteen-year-old professional Go player Kim Eun-ji was suspended from competing for one year in late November after she admitted to using artificial intelligence (AI) to enhance her gameplay in an online Go competition. The Korea Baduk Association took the punitive measure against Kim Eun-ji, a 2-dan professional Go player who had been considered a genius in the Korean Go scene and the youngest professional player, for violating the rules as a professional Go player and on ethics which stipulate that a player cannot receive outside advice in official competitions. Fellow Korean pro Yeonwoo Cho devoted one of her videos to the incident.
– Excerpted from a report in The Korea Times

Playing Go with Darwin
In Playing Go with Darwin (Nautilus 12/16/2020), David Krakauer writes that “Meditating on some subtleties of (Go’s) strategy can, I think, illuminate our understanding of the strategic character of evolution.” He adds that “Go today has become an epitaph on the tombstone in the cemetery of human defeat at the hands of algorithmic progress” and says “Charles Darwin was very likely the first person to have understood nature in terms of a game played across deep time. I have wondered how much further the Chess-playing naturalist might have taken this metaphor if, like Kawabata, he had studied Go.” It’s a fascinating article about how new research elevates evolution from a tactical process to one of strategic possibility. Thanks to Peter Freedman for passing it along.

John Conway

Remembering John Conway
John Conway is one of Three Mathematicians We Lost in 2020 (The New Yorker 12/31/2020), and midway through the story there’s this:
At Princeton, he could usually be found not in his office—which resembled a mathematical apothecary shop hit by a tornado—but in the large and somewhat soulless common room of Fine Hall, the massive looming tower, on the edge of the Princeton campus, that is the home of the mathematics department. The common room would come to life only in the mid to late afternoon, just as things were revving up for the daily “tea,” a small box-cookie reception roughly marking the time when most classes had ended and a few seminars were about to start. Conway would often hold court there, hard to miss, a cross between Rasputin and a Middle Ages minstrel, loudly talking philosophy and mathematics, playing the board game Go, or engaging in some other kind of mathematical competition, surrounded by adoring and admiring students, faculty, and visitors.

The Power Report: Ueno wins Women’s Kisei; Chunlan Cup

Monday March 1, 2021

by John Power, Japan correspondent for the E-Journal

Ueno wins Women’s Kisei

Ueno Asami

Ueno Asami, who is still a teenager (she turned 19 on October 26) has confirmed her ranking as the number two woman player in Japan by becoming a dual title-holder again. In the 24th Women’s Kisei best-of-three title match, she made a bad start but fought back to take the title from veteran player Suzuki Ayumi (aged 37). In the final game, Ueno scored a decisive win, capturing a group when Suzuki made an overaggressive cut in an attempt to maintain territorial parity. After the game, Ueno revealed that she prepared for the third game with intensive study of life-and-death problems, including competing with her younger sister, Risa 1P, to see who could solve 100 problems more quickly—she won three times out of five. On the morning of the game, she followed her usual routine before a game of skipping rope: 777 times (it took her about ten minutes). First prize is 5,000,000 yen (about $48,000 at $1 = 104 yen). She lost this title to Suzuki last year; she also holds the Senko Cup. Results:

Game 1 (Jan. 21). Suzuki (B) by resig.
Game 2 (Jan. 28). Ueno (B) by resig.
Game 3 (Feb. 8). Ueno (W) by resig.

Chunlan Cup

The quarterfinals and semifinals of the 13th Chunlan Cup were held in January (Details of the first two rounds are given in my report of August 25). Like all international events these days, games were played on the net. As in many international tournaments, the final (schedule not yet decided) will be Korea vs. China, pitting the world’s top-rated player, Shin Jinseo 9P of Korea), against Tang Weixing 9P of China. On the site “Go Ratings,” Tang is listed as no. 32 in the world; this is a little hard to understand, as he won the 24th Samsung Cup in 2019 and the 8th Ing Cup in 2016. Results follow.

Quarterfinals (Jan. 18): Ke Jie 9P (China) (B) beat Hsu Hao Hong 6P (Chinese Taipei) by resig.; Tang (W) beat Park Yeonghun 9P (Korea) by resig.; Lian Xiao 9P (China) (B) beat Byan Sangil 9P (Korea) by resig.; Shin (W) beat Fan Yuting 9P (China) by resig.

Semifinals (Jan. 20): Tang (W) beat Ke by resig.; Shin (B) beat Lian by resig.
