AlphaGo Zero vs. Master with Michael Redmond 9p: Game 8

Saturday April 14, 2018

Michael Redmond 9p, hosted by the AGA E-Journal’s Chris Garlock, reviews the eighth game of the new AlphaGo Zero vs. 2018.04.14_AG Zero-Master8Master series.

“Zero just doesn’t care about its opponent’s moyo,” says Redmond. “It can do anything inside the moyo. Human pros who have tried to emulate this strategy have just crashed almost every time. Miserably. But Zero has no trouble dealing with its weak groups, so in this game we’re going to see a lot of dancing around inside Master’s moyo. Plus a really weird endgame.” Redmond also has some interesting observations about the similarities — and differences — between top human players and AI players.

Friday April 13, 2018

Join Chris Garlock and Michael Redmond 9p for Episode 10 of Redmond’s Reviews. In this game, Michael plays against 2018.04.07_redmond-mizokamiMizokami 9p in the Kisei – First Tournament. “Mizokami is a very tenacious, steady player who I’ve had no success against in the past,” says Redmond, “but my new style works better this time.” Viewer Dontbtme calls it a “very interesting and inspiring game, showing (once again) how go is a game so deep it’s got room enough for even pros to make many mistakes and then recover.”

The Janice Kim Files: On Ranks

Monday April 9, 2018

by Janice Kim 3P2018.04.08-janiceKim

When I was a student at the Korean Baduk Academy, I was firmly ensconced in the “B League” at 6 “gup”, or “kyu”. The way the ranking system worked is that a 6 kyu would give a 5 kyu only three points of komi for White, rather than 5.5 or 6.5 points. It then went no komi, 3 points reverse komi, then 6 points, then 9 points reverse komi. The two-stone handicap gap was considered so big, you didn’t get there until a 6 kyu was playing against a 1 dan (that’s 1 dan pro). Clearly one rank did not equal one stone.

The general go-playing population, even in Korea, didn’t know or use this kind of system. At best, you’d see the strongest players say something about being “1 gup.” There was whispering that there was such a thing as an amateur dan, but it was hard to confirm the rumor, unless you met someone who had “Amateur 4 Dan” or something like that printed on a business card. This was a signal that this person might do something completely bizarre in Korean society, like sit in a seat of honor at a banquet. Also that this person had no intention of ever exceeding this rank. Or else his family owned the banquet hall, and was paying for the whole shebang.

That’s why “gup” doesn’t exactly translate to “kyu.” Basically, strap in to your seat if the person says he or she is any “gup”. This is reminding me of when I was introduced as a “Korean 3 dan pro” to Yoda 9 dan at a banquet. He looked mildly interested, perhaps concerned, until someone whispered, “Not one of those Korean 3 dan pros.” Note that being female had nothing to do with it, it just had to be established I was not Lee Sedol, who was also 3 dan pro at the time.

On my visa renewal application, there’s a question in English, “What is your purpose for being in Korea?” I painstakingly write out “Professional Baduk researcher” in my childish Korean script. My aunt sees this, scowls, and crosses it out. Then, in her easy way, she fits in a neat sentence that I’m learning how to play. I’m almost incapable of saying or writing anything in Korean now. This is an utter disaster when anyone, naturally, assumes that I can communicate or translate from Korean to English or vice-versa. Imagine translating this into Korean. You’d have to cross the whole thing out, and say “She’s struggling to explain an existential crisis.”

It was so hard, during the peak of the AlphaGo phenomenon, to talk about things. For example, one did not want to tearfully start screaming, “You don’t understand how big a two-stone handicap gap is, that’s not even something we ever did!” when somebody started suggesting handicaps for pros against AlphaGo. Don’t get me started on winning percentages, like people of a certain skill level couldn’t just be relied on to calculate their reverse komi or whatever in a game, and play sub-optimally to win. Or like AlphaGo had invented something novel in not caring about the size of the win, or altering the strategy depending on the situation.

So there I am on the bus, which could preface a significant chunk of my entire waking life in Korea. Somebody is looking at me with my nose in my life and death book, and announces, “That’s easy.” I’m startled. Is it possible that I’m missing something obvious? I thought it was really hard. “Black lives”, my seat mate says. Well, yes. It says that right on the problem. But how?

Sensing my confusion, my seat mate starts turning pages. “Black lives. Black lives. White lives.” Then he hits one of my game records stuck in the pages of the book, where I’ve dutifully recorded my rank as “6 gup”. He smiles, looking at the shape of the finished game, which now suddenly looks pretty silly, with large territories like empty continents on a flat earth. “Black loses.”

I’m suddenly furious. When we get to my stop, I insist, practically pulling on the man’s sleeves, that he get off at the same stop, and accompany me to the Korean Baduk Association building. There I crush him in a game, in the most stupid and mindless way possible. He apologies profusely, and runs, literally runs, for the door.

The 6 gup, full of ego and self-doubt, crushes this nice man, guilty of nothing more than trying to be helpful to the young girl looking at a go book on the bus. The 3 dan teaches this man how to play go, but he already knows how. There is a game-changing difference between them. Like a 2-stone handicap.

Here’s a link to the Blue Oyster Cult song “Shooting Shark.” The lyrics are funny, especially if viewed entirely in a go context. I picked a video that didn’t have inappropriate content, although G-d knows anyone can write anything in the comments.

The Empty Board: Philosophical Reflections on Go

Tuesday April 3, 2018

by William Cobb2018.04.03_P1230835-tri-tone

“Go is like life.” It’s a common claim—and true. But go is also like death. Every game comes to an end and every player eventually plays their last game. Is that a bad thing? With individual games, even if you lost, you always made some good moves and there’s always next time. But what about that final game? Does the fact that it’s inevitable mean that playing is a waste of time? Of course not. Each game is an end in itself. You don’t have to play forever for them to be one of the best parts of life. The same goes for all of life’s games. The fact that they come to an end and there is no continuation does not undermine the enjoyment or the significance of life. A lot of people seem to be confused about that.

The Power Report (2): Iyama wins NHK Cup; Meijin League; Honinbo League; Iyama extends lead in Judan

Monday April 2, 2018

by John Power, special Japan correspondent for the E-Journal2018.04.02_65nhk_1

Iyama wins NHK Cup:
The final of the 65thNHK Cup was telecast on March 18. Playing black, Iyama Yuta, the current titleholder, defeated Shida Tatsuya 7P by half a point. Shida narrowly missed out on his first title. He took the lead in the middle game, but Iyama fought back tenaciously and eventually overhauled him. After that, the tables were turned, with Shida threatening to undo the upset, but Iyama just managed to fend him off. He is the fourth player to win the title in successive years. This is his 50th title (actually, the game was recorded just before he defended the Kisei title, so that is really his 50th).

Meijin League: Here are the details for the result given in my previous report: Shibano Toramaru 7P (W) beat Yo Seiki 7P by resig.

Honinbo League: An important game was played on March 22. Yamashita Keigo (W) beat Ida Atsushi by resig. Previously, Ida had enjoyed the sole lead, but now he and Yamashita and Ko Iso 8P were tied on 4-2. The final round will be played on April 5. Yamashita and Ko will play each other, and Ida will play Shibano Toramaru.

Iyama extends lead in Judan: The second game of the 56th Judan title match was held at the Toda City Culture Hall in 2018.04.02_56jyudan2_9-2Toda City, Saitama Prefecture, on March 22. Iyama Judan (B) fought aggressively and took an early lead. Murakawa Daisuke 8P, the challenger, recovered and made the game closer. He then made an aggressive invasion, but his group was killed, so he had to resign after 215 moves. This was Iyama’s second straight win, so Murakawa is faced with a kadoban. The third game is scheduled for March 12.

Promotion
To 3-dan: Komatsu Daiki (40 wins, as of March 23) (Komatsu is the son of Komatsu Hideki 9P and Komatsu Hideko 4P.)

Power Report (1): Yu wins Senko Cup; Park repeats in World Go Championship

Sunday April 1, 2018

by John Power, special Japan correspondent for the E-Journal

Yu wins Senko Cup: The Senko Cup World Women’s Go Tournament 2018, to give it its full name, is a new international 2018.04.01_Senko 3rd playoff Rina R Choi Ltournament founded by the sponsors of the Japanese Senko Cup. The main sponsor is Senko Group Holdings, whose main business seems to be transportation; they are supported by Asahi Kasei, Sekisui House, and JAL, among others. At present, the Senko Cup has the top prize money for domestic women’s tournaments of eight million yen. One of the aims of founding the international tournament is to give local players more international experience. There are eight participants, four from the host country (two of whom are actually from Taiwan), and one each from China, Korea, Taiwan, and Europe. First prize is ten million yen (about $95,000), with three million yen for second, two million for third, and one million for fourth. The inaugural tournament was won by Yu Zhiying of China, a 20–year-old who has established herself as the world’s top woman player these days. In the final, Hei Jia-jia lost on time, but she was behind anyway. Full results follow:
Round 1 (March 14). Fujisawa Rina 3P (Japan) (B) beat Natalia Kovaleva 5D (Russia) by resig.; Yu Zhiying 6P (China) (B) beat Xie Yimin 6P (Japan) by resig.; Choi Jeong 9P (Korea) (W) beat Mukai Chiaki 5P (Japan) by resig.; Hei Jia-jia (Joanne Missingham) 7P (Taiwan) beat Nyu Eiko 2P (Japan) by resig.
Semifinals (March 15). Hei (W) beat Fujisawa by 1.5 points; Yu (B) beat Choi by resig.
Final (March 16). Yu (W) beat Hei on time.
Play-off for 3rd place (March 16). Choi (W, at right) beat Fujisawa (left) by resig.

Park repeats in World Go Championship: This is another new international tournament, started last year by the Nihon2018.04.01_Park right Iyama L Ki-in with the support of sponsors such as NTT DoCoMo, Mitsui Sumitomo Card, and others. First prize is 20 million yen (about $190,000). In the inaugural tournament, there were four competitors: three players and one computer program. The format was an all-play-all league, and they finished in the order of Park Junghwan (Korea) (3-0), Mi Yuting (China) (2-1), DeepZenGo (1-2), and Iyama Yuta (0-3). Incidentally, the prize then was 30 million yen. In the second championship, which is called World Go Championship 2018, there were six players, with two from Japan, two from Korea (with Park being seeded), and one each from China and Chinese Taipei. Top honors again went to Park Junghwan, who beat Ke Jie in the semifinal and Iyama Yuta in the final. The time allowance is three hours each, with the last five minutes being allotted to byo-yomi. Results are given below:
Round 1 (March 17). Yamashita Keigo 9P (Japan) (W) beat Wang Yuanjun 8P (Chinese Taipei) by resig.; Ke Jie 9P (China) (W) beat Shin Jinseo 8P (Korea) by resig.
(Semifinals) (March 18). Park Junghwan 9P (Korea) beat Ke Jie by resig.; Iyama Yuta 9P (Japan) (B) beat Yamashita by resig.
(Final) (March 19). Park (W, at right) beat Iyama (left) by resig.
In this tournament, Park was seeded into the semfinals as the previous winner. Iyama was seeded on the wishes of the sponsors. Yamashita earned his place by winning a qualifying tournament. Shin (aged 18) earned his place as the second-ranked player in Korea and Wang (22) as the top-rated player in Chinese Taipei. Seeding the previous winner is common (for example, the TV Asia tournament does it), but not everyone approved of the seeding of Iyama. Ke Jie commented at the press conference: “I was surprised by the seeding.” However, it was just the luck of the draw that matched Ke and Park, the world’s top-rated players (apparently, Park has recently regained the number-one position) in the semifinal. After his loss in the final, Iyama’s career record against Park was 2-4.

Tomorrow: Iyama wins NHK Cup; Meijin League; Honinbo League; Iyama extends lead in Judan

AlphaGo Zero vs. AlphaGo Lee: Game 1

Thursday March 29, 2018

Michael Redmond 9p, hosted by the AGA E-Journal’s Chris Garlock, reviews the first game of the new AlphaGo Zero vs. AlphaGo Lee series. In this game, we see AlphaGo Lee “playing very human-like moves,” says Redmond. Zero “builds a big moyo and then turns it into territory,” which Redmond says “doesn’t usually happen in these games. Usually a lot of stuff 2018.03.23_ag-zero-vs-ag-lee-game1-screenshothappens before it gets into (making) territory.”

“Refreshing change of pace with this game,” says Rory Mitchell. “Thanks for the wonderful videos,” says Ryan Smith. “These are the highlight of my week.”

The Power Report (2/2): Iyama wins first Judan game; 73rd Honinbo League; 43rd Meijin League

Monday March 19, 2018

by John Power, special Japan correspondent for the E-Journal2018.03.19_56jyudan1_4

Iyama wins first Judan game: The Judan best-of-five got off to a start on March 6. It was played at the same venue as the Women’s Meijin game, as detailed above. These two titles share a sponsor, the Sankei Nerwspaper, and it has been the practice in recent years to link them in this way. The challenger is Murakawa Daisuke 8P, who has been the top young player at the Kansai Ki-in for some time now. This is his fourth title match with Iyama. His first challenge was the only successful one: he scored 3-2 and took the 62nd Oza title from Iyama in 2014, but the following year he lost it to him 0-3. He also lost the 41st Gosei title match to Iyama by the same margin in 2016. This is the reverse of the usual pattern, in which a young player fails in his first challenge but does better later. 2018.03.19_56jyudan1_5Murakawa’s record so far against Iyama is three wins to 14 losses: his only wins have come in their first title-match clash.
In the first Judan game, Murakawa drew black in the nigiri. The tenor of the game was set quite early when Iyama played a cleverly timed sequence that turned an earlier move of his into an efficient forcing move. After that, the game developed peacefully for a while, but that was misleading; in the end, it turned into a capturing race between two large groups. This was won by Iyama, so Murakawa had to resign after 156 moves. The second game will be played on March 22.

73rd Honinbo League: The Honinbo League is one round and one game away from finishing. As before, Ida Atsushi 8P has the provisional lead, but he hasn’t yet played his sixth-round game against Yamashita Keigo 9P. Motoki is on 4-1. Yamashita on 3-2, and Ko Iso 8P on 4-2. One of these three will be the challenger. Results of recent games are listed below.
(March 1) Ko Iso 8P (B) beat Shibano Toramaru 7P by resig.
(March 8) Motoki Katsuya 8P (B) beat Yo Seiki 7P by resig.; Kobayashi Satoru 9P (B) beat Hane Naoki 9P by resig.

43rd Meijin League: After four rounds of the league, two players share the lead: Cho U 9P and Shibano Toramaru 7P. both 2-0 (both have already had their byes). Recent results:
(March 1) Hane Naoki 9P (W) beat Yamashita Keigo 9P by resig.; Cho U 9P (W) beat Murakawa Daisuke 8P by resig.
(March 8) Kono Rin 8P (B) beat Takao Shinji 9P by resig.
(March 15) Shibano beat Yo Seiki (don’t have details yet).

Promotion
To 3-dan: Tanimiya Ayako (40 wins; as of Feb. 27). Tanimiya earned her promotion after 37 years as 2-dan.
