The Power Report: Hoshiai’s first challenge; Ichiriki takes lead in Meijin; Ichiriki wins Kisei S League

Notizie AGA - Mer, 22/09/2021 - 23:04

by John Power, Japan correspondent for the E-Journal

Hoshiai Shiho 3P

Hoshiai to make first challenge
The play-off to decide the challenger to Fujisawa Rina for the 40th Women’s Honinbo was held at the Nihon Ki-in in Tokyo on August 23. Taking black, Hoshiai Shiho 3P (right) beat Koyama Terumi 6P by resignation. She will make her first challenge for a title. She may be a new name for some readers, but actually she is one of the best-known women players in Japan, as she has been serving as the MC of NHK’s TV tournament telecast on Sundays. Hoshiai turned 24 on September 4. The title match begins on September 28. Her opponent, Koyama Terumi, deserves praise for reaching the play-off. In an era of domination by young stars, the 51-year-old Koyama revived memories of her younger days when she won the Women’s Meijin title four times (1996‾98, 2005).

Shiki-sai Ichiriki or Four Seasonal Colors Ichiriki

Ichiriki takes lead in Meijin title match
This year’s 46th Meijin title match features what is undoubtedly the strongest pairing in current tournament go in Japan. Iyama held the top three titles and has continued to lord it over the go world despite entering his 30s. The challenger, Ichiriki Ryo, has been the in-form player in recent months and has looked the most likely to dethrone Iyama. However, although he has won 14 titles, he has not yet won one of the big three, unlike his closest rival, Shibano Toramaru. This match is his chance to rectify that.
The first game of the match was held at its customary venue of the Hotel Chinzanso Tokyo in Bunkyo Ward, Tokyo, on August 26 and 27. Iyama drew white in the nigiri. Both players played aggressively, so the game featured fierce fighting throughout, making this a spectacular start to the title match. However, Ichiriki’s strategy at an important point in the middle game was a little dubious, so Iyama took the lead. Ichiriki made an all-out attempt to capture a large group, but White cut off a black group and won the capturing race with a brilliant combination, one that he apparently worked out 25 moves in advance. Ichiriki resigned after move 212.
The second game was played at the Shiki-sai Ichiriki or Four Seasonal Colors Ichiriki in Koriyama City, Fukushima Prefecture, on September 8 and 9, Ichiriki being written with the same characters, “one strength,” as in the player’s name. Although there’s no connection between the family that founded the inn and Ichiriki’s family, it was a pleasant coincidence for Ichiriki (the venue would have been chosen before the organizers knew who the challenger would be). The game was a real rough-and-tumble affair, with various moves supposed to be bad style, such as empty triangles and moves pushing through a knight’s move, appearing in the messy infighting. Iyama (B) delivered what Go Weekly called “unlimited punches,” with Ichiriki sometimes absorbing the impact, sometimes dodging lightly. Ichiriki had an edge, but in the endgame he missed a move that would have secured a win, so the game became a half-pointer. However, Iyama later made a mistake, so the half point went in Ichiriki’s favor. This was Ichiriki’s first win in a two-day game?he lost 0-4 when he challenged Iyama for the 42nd Kisei title in 2018.
The third game was played at Kakujoro inn in Tahara City, Aichi Prefecture, on 15 & 16 September, with Hane Naoki acting as referee. Ichiriki (B) got into trouble when he came under a severe attack, but he was able to pull off an upset. Iyama resigned after move 225. The fourth game will be played on September 28 and 29.  

Ichiriki wins Kisei S League
In a repeat of his Meijin League performance, Ichiriki Ryo has won the S League of the 46th Kisei tournament without dropping a game. Second place was taken by Yo Seiki 8P of the Kansai Ki-in. Results since my last report are given below.
(Aug. 16) Murakawa Daisuke 9P (W) beat Yamashita Keigo 9P by resig.
(Aug. 23) Ichiriki (B) beat Takao Shinji by resig.
(Sept. 16) Yo Seiki 8P (W) beat Murakawa Daisuke 8P by 2.5 points.
The final-round game between Kono Rin and Yamashita Keigo has yet to be played.

The winners of the other leagues have also been decided, though not all the games have been played yet. In the B League play-off, Son Makoto 7P, who won the B2 League with 6-1, defeated Shida Tatsuya 8P, who won the B1 League with 5-2. The game was played on September 6, and Son, taking black, won by resignation. The knock-out to decide the challenger looks like this: Numadate Sakiya 7P, winner of the C League, plays Son Makoto; the winner then plays Shibano Toramaru, winner of the A League; the winner plays Yo Seiki 8P, who came second in the S League; the winner then plays Ichiriki in a “best-of-three” in which Ichiriki has a one-win advantage, so he needs to win only one game to become the challenger.

With fewer than 12 months remaining in Terpstra’s term, the AGA Board appointed Justin Teng to serve the remainder as Board Member At-Large (through August 31, 2022). “Justin is well known as a strong player and tournament organizer, particularly through his work with youth with the Redmond Cup and Girls Championship,” said Board Chair Lisa Scott. “We are pleased to have him join the AGA Board.”

The Power Report: Ichiriki perfect in Meijin; Ueno into King of the New Stars final; Iyama wins Gosei, 65th title

Notizie AGA - Lun, 20/09/2021 - 23:19

by John Power, Japan correspondent for the E-Journal

Ichiriki

Ichiriki’s perfect record in Meijin League
The final round of the 46th Meijin league was held on August 6. There was no suspense at the top of the league, as Ichiriki had taken an unbeatable lead of 7-0 in the previous round, but at the other end there were issues of demotion still to be decided. Kyo Kagen, Hane Naoki, Yamashita Keigo, and Shibano Toramaru were sure of their places. Yo Seiki, who had a bye in the last round, was the only player sure of dropping out. That meant that out of Kono Rin, Motoki Katsuya, and Anzai Nobuaki, two would have to drop out. Complete results for the final round follow:
Ichiriki Ryo Tengen (W) beat Yamashita Keigo 9P by resig.
Kyo Kagen Judan (W) beat Kono Rin 9P by half a point.
Motoki Katsuya (W) beat Hane Naoki 9P by resig.
Anzai Nobuaki 9P (B) beat Shibano Toramaru Oza by resig.

The position became simplified when Motoki won his game. He improved his score to 4-4 and took 5th place. Anzai needed not just to win but also to have Motoki (and Kono) lose, in which case there would be a play-off with Motoki for the sixth seat. This happens only when the players have the same rank, so this rule applies only to the three newcomers to the league, who are all ranked 7th. That’s why Anzai didn’t get a play-off with Shibano, although they finished on the same score. Shibano’s luck in keeping his place with a 3-5 score is indicative of how the Meijin League favors the status quo. In the Honinbo League, a score of 4-3 is sometimes not enough to keep your place. Incidentally, Kono is enduring one of the worst slumps of his career, the loss above being his 11th in a row. This was his 10th Meijin League in a row and the first time he lost his seat.

Ueno makes King of the New Stars final
On August 9, Ueno Asami, Women’s Kisei, (W) beat Nishi Takenobu 5P in the semifinal of the 46th King of the New Stars tournament by 4.5 points. This made her the second woman player to make the final. The first was Aoki Kikuyo 8P (then 7P) in the 22nd title. The other finalist is Sotoyanagi Sebun 3P; the best-of-three starts on September 20.

Iyama

Iyama wins Gosei, once again
The fourth game of the 46th Gosei title match was held at the Niigata Grand Hotel in Niigata City on August 17. Taking white, Iyama Yuta won by resignation after 198 moves and so survived a kadoban. He played quite aggressively and did not seem to fall behind at any stage. The highlights of the game were two brilliancies played by Iyama. One was a surprising move adding a stone to three captured white stones, but giving White leverage that he used in his second brilliancy. Incidentally, the referee for this game was Cho U. Aged 41, Cho was making his debut in this role. He was also the referee for the first game in the Meijin title match (see below). It’s a little unusual to choose as referees players who are still competing at the top. Cho is slated to play Iyama in the semifinal of the 69th Oza tournament; if he won that game, he would meet Ichiriki in the final to decide the challenger. (As it happened, Iyama beat Cho.) Actually, it’s not just Cho. The other three members of the group popularly called “the top four of the Heisei (1989-2019) era,” that is, Takao Shinji, Hane Naoki, and Yamashita Keigo, are also serving as referees for the Meijin title match.
The fifth game was held at the Nihon Ki-in headquarters in Tokyo on August 29. Iyama drew white in the nigiri and continued where he left off in the fourth game. He took the edge in the middle game, so Ichiriki felt that he had to stake the game on attacking a large white group. When this attack failed, he resigned. The game lasted 180 moves.
Iyama regained the title that he had held for six years in a row (2012‾2017: 37th to 42nd). He lost it to Kyo Kagen in 2018, who lost it to Hane Naoki in 2019, who lost it to Ichiriki Ryo in 2020. Perhaps a new dynasty will start. Iyama once again becomes a quadruple title holder. This is his 65th title, so he moves ahead of Sakata Eio into sole second place on the all-time list:.
Most titles won
1. Cho Chikun: 75
2. Iyama Yuta: 65
3. Sakata Eio: 64
4. Kobayashi Koichi: 60
5. Otake Hideo: 48
6. Kato Masao: 47
7. Cho U: 41
8. Yoda Norimoto: 36
9. Rin Kaiho: 35
10. Xie Yimin: 27

Speaking of which, in case you missed it, AlphaGo vs. AlphaGo Game 51 — which aired live on August 8 — was posted August 20, and features “Tesujis, Semiaias, Forever Kos and Fuzzy Sekis,” according to Damon Skinner. “This game is even more complicated and deep than we imagined.” Mark your calendar now for the next live Redmond game commentary, set for Sunday, October 10, 7p ET on the AGA Twitch channel.

Ōtake Hideo defends the All Japan First Place Title

From August 10 we see Ōtake Hideo 9d in triumph over Katō Masao 7d in the All Japan First Place Title. Ōtake’s 2-0 victory meant that he now had held the title for 4 straight years. (Game records: Game 1, Game 2.)

The first game of the Meijin Title took place on August 20 and 21. Fujisawa Shūkō, the title holder, confidently dominated his young challenger, Rin Kaihō…until he made one of his fateful blunders on move 131, going on to lose the game. Sakata Eio watches as Rin shares his thoughts with a dismayed Shūkō. (Game record: Meijin Game 1.)

Rin Kaihō wins Meijin Game 1

On August 15, the ladies of Koyukai once again took on the best foreign players for the fourth time. The games ended 4-4-2 so for the first time the guests did not win. Wins by notables Manfred Wimmer, Horst Mueller, and James Davies were offset by losses by Richard Bozulich and James Kerwin.

On 29 to 30 August, Nihon Ki’in’s young professional players went on a biking trip at the Cycle Sports Center in Izu, by invitation from the Japan Bicycling Promotional Association (Nihon Jitensha Shinkōkai, which later would be absorbed into the present-day Japan Keirin Autorace Foundation).

Go Spotting: GOD, HUMAN, ANIMAL, MACHINE: Technology, Metaphor, and the Search for Meaning

Notizie AGA - Ven, 27/08/2021 - 03:02

“Imagine sitting down to a game of Go,” writes Becca Rothfeld in The New York Times, “not in a cafe or a park, where you could banter with your adversary or discuss strategy with onlookers, but alone in front of a screen. Your opponent is not a person but an algorithm, AlphaGo, a program created by Google’s machine-learning subsidiary, DeepMind. Squinting into the cool glare of your monitor, you manipulate digital pieces. You touch nothing tangible: You are unable to scrutinize the expressions of your faceless competitor.”

“These, roughly, are the strange and surgical circumstances under which Lee Sedol, one of the best Go players in the world, was vanquished in a best-of-five match in 2016,” Rothfeld writes. “As the essayist and cultural critic Meghan O’Gieblyn reports in her nimble new book, ‘God, Human, Animal, Machine: Technology, Metaphor, and the Search for Meaning,’ one former Go champion watched the game and exclaimed that AlphaGo’s winning maneuver was “not a human move.” Read the rest of the review here.
