Go Spotting: Japanese firefighting jacket

Tuesday November 7, 2017

This 19th-century Japanese firefighting jacket is in the collection at the Seattle Art Museum. “The jacket tells a story from the life of Minamoto2017.11.07_firemans-coat-go-spider-1080px no Yorimitsu (948–1021), a warrior-hero,” according to a recent post on the museum’s blog. “The story is as follows: Yorimitsu was sick, and was resting in bed. He was visited by a priest—but the priest was actually a giant spider (tsuchigumo) in disguise! Yorimitsu, being very clever, sees through the disguise, and attacks the spider with his sword, wounding him. Yorimitsu’s four attendants, called the Four Heavenly Kings, were playing a game of go while guarding him, and leapt up to track the spider back to his den.

This narrative was popular in theatrical productions, and there was a song in Noh theatre specifically about tsuchigumo, the intimidating earth spider. The story appears frequently in woodblock prints in the nineteenth century as well. The jacket shows the moment when the go game was abandoned, with tsuchigumo retreating back to his web. So great was the hurried effort to find the spider that the attendants left behind their personal effects, scattering go pieces in their haste.”

Saturday November 4, 2017

“We were expecting DeepMind to make some sort of an announcement (about a new version of AlphaGo),” says Michael Redmond 9p, “But 802017.11.04_agzupdatethumb games was a big present.” (Self-taught AlphaGo Zero bests all previous versions in record time Redmond discusses AlphaGo Zero with the E-Journal’s Chris Garlock in a brief video announcing the launch of a new series of game commentaries. DeepMind released four sets of games for the self-taught AI, including training games, games against the Fan Hui version, the Lee Sedol version and the Master version, which defeated 60 top human opponents earlier this year. “I’m going to be looking at the games where Master plays Zero, mainly because Master is such a popular version of AlphaGo,” Redmond says. Master’s tactics, including big shimaris and emphasizing the center “people wanted to play, but were afraid because that way of playing is weak in territory. Master showed us some successful ways…and is still having an effect on how professionals play. So it’s going to be really interesting to see Master playing against a stronger version of AlphaGo.”

The Power Report: Iyama defends Meijin, achieves second Grand Slam; Iyama makes good start in Oza; Iyama extends lead in Tengen; Yamashita makes Kisei playoff; Fujisawa evens score; First round completed in 73rd Honinbo League

Iyama defends Meijin, achieves second Grand Slam: The fifth game in the 42nd Meijin title match was held at the Atami Sekitei inn (below left), one of the traditional venues for the Meijin, in Atami City in Shizuoka 2017.10.29_43meijin5_8Prefecture on October 16 and 17. After winning the first game in the match, the defending champion, Takao Shinji Meijin, had lost three in a row, so he faced his first kadoban. The game got off to a stormy start, with Takao, who had white, capturing a large group of Iyama Yuta’s. Actually Iyama (right) could have made a second eye, but he didn’t like the result, so instead he discarded the group and tried to squeeze on the outside as compensation. As usual, it was a fierce game, and the lead switched back and forth. In the end, Iyama set up a ko to kill the white group surrounding his “captured” group, and Takao had to resign when he ran out of ko threats.

2017.10.29_42meijin5 TakaoLosing this title to Takao (left) last year cost Iyama his simultaneous grand slam, the first in Japanese go history. In the meantime, he defended his other six titles, so regaining the Meijin gave him his second grand slam, a first for. This is a first for go or shogi. Iyama maintained the first one for 197 days. Fans will be looking forward to his extending this. This is his 46th title, which leaves him in sixth place, one behind Kato Masao.

Yamashita makes Kisei playoff: The third game in the knock-out to decide the challenger in the 42nd Kisei tournament was played on October 27. Motoki Katsuya 8P had done well, moving up from bottom of the knock-out, as C League winner, past the B and C League winners, but his run came to a stop when he met Yamashita Keigo 9P, second-place-getter in the S League. Taking black, 2017.10.29_female-honinbo2 FujisawaYamashita won by resig. He will meet Ichiriki in the final, though the latter starts with a one-win advantage.

AlphaGo-AlphaGo Game 13: The large knight’s move enclosure workout

Sunday October 29, 2017

“This is a very different game, in that there are three corner enclosures,” says Michael Redmond 9p in his game commentary on AlphaGo-2017.10.27_AG-13AlphaGo Game 13. “Black isn’t playing a kakari, which is different from what human players do now. So we’re going to have kind of a workout in how to deal with the large knight’s move enclosure.”

Grandmaster Morozevich on go, computers and cheating

Sunday October 29, 2017

Alexander Morozevich was once live-rated world no. 1, but at the age of 40 the Russian grandmaster has dropped to world no. 79 and barely2017.10.29_morozevich-barsky plays classical events, reports chess24. In a recent interview he talked about what he’s currently up to, explaining his fascination with go and how he’s watched as computers have conquered that game just as they did chess during his career. “I see very similar processes in what Go is going through and what happened in chess 10-15 years ago…For now it’s not quite formalised, but gradually, I think, they’ll follow the same path that we followed in chess.” In the article, Morozevich also talks about what he sees as the chess world’s reluctance to take cheating seriously, despite computer “doping” being so much more powerful than drugs in other sports.
