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.

AlphaGo vs. AlphaGo; Game 17: Fun with kos

Sunday March 18, 2018

Michael Redmond 9p, hosted by the AGA E-Journal’s Chris Garlock, reviews the 17th game of the amazing AlphaGo vs. AlphaGo2018.03.16_AG-KJ-self-play17_screengrabselfplay games. “There’s a bit of fun with kos,” says Redmond. “And there’s a new move that’s become popular in pro play. It’s an interesting and close game and AlphaGo finds a very unusual way to finish it off.”

“Master versus Master games are my favorite go videos” says Alek Erickson. “I love these self-play games,” agrees Melinda Green. “Amazing game and beautiful analysis,” adds GerSHAK.

The Power Report (1/2): Korea wins Nong Shim Cup; Fujisawa defends 30th Women’s Meijin; Kato & Iyama win Pair Go

Sunday March 18, 2018

by John Power, special Japan correspondent for the E-Journal2018.03.18_19noshin10_1-2

Korea wins Nong Shim Cup:
  The final round of the 19th Nong Shim Spicy Noodles Cup was held in Shanghai from February 26 to March 1. Recently, victory in this three-way team tournament had been monopolized by China, but this time they were thwarted by Korea.
To recap, the first Korean player, Shin Min-jun 6P, gave his team a great start by winning all four games in the opening round, held from September 19 to 22. In the second round, held from November 24 to 28, he picked up two more wins before losing to Dang Yifei of China (at right in photo). Dang closed out this round with two more wins, so only two players had any success in the first two rounds.
In the first game of the final round, Game 10, Dang played Iyama Yuta 9P of Japan, who was his country’s last hope. Dang (W) won by resignation, so this was another international failure for Iyama, following on his loss in the LG final. In Game 11, played on February 27, Dang (W) beat Shin Jinseo 8P of Korea by resignation so he extended his winning streak to five games. In game 12 (February 28), Kim Jiseok 9P of Korea (W) scored a dramatic win over Dang by just half a point, so he prevented Dang from matching Shin’s record. In game 13, played on March 1, Kim (B) beat China’s top board, Ke Jie 9P by resignation. This secured Korea its first victory in the Nong Shim Cup since the 14th term without having to call upo2018.03.18_30fmeijin2_2n their top board, Park Junghwan. Korea scored eight wins to three losses, China 5-5, and Japan 0-5. Japan came third for the 12thyear in a row, but it was only the second time it failed to pick up even one win.

Fujisawa defends 30th Women’s Meijin: Recently, most of the women’s title matches have featured Xie Yimin playing Fujisawa Rina, but this year’s Women’s Meijin title match was different, with a member of an older generation trying to make a comeback. The challenger was Yashiro Kumiko (below left), who won a couple of titles over a decade ago, and the defender was Fujisawa Rina, who holds three of the top five women’s titles. The first game 2018.03.18_30fmeijin2_3was played on February 28 in the Arisu Building at the Heian Jogakuin University, an Anglican-linked women’s university also known as St. Agnes’ University. The Arisu Building is a former nobleman’s resident that is on the campus. According to Go Weekly, Fujisawa’s play “overflowed with fighting spirit.” She held the initiative throughout and forced a resignation after 196 moves (she had white). The second game, which was played on the campus of the Osaka University of Commerce on March 7, developed differently, with Yashiro taking the lead. However, she let Fujisawa pull off an upset late in the game and win by 3.5 points. This meant that Fujisawa defended her title with straight wins. Surprisingly, this is her first successful defence, which is not what you would expect of a player who not so long ago held four of the top five women’s titles. First prize is 3,500,000 yen (about $32,000).

Kato & Iyama win Pair Go: The final of the Professional Pair Go Championship 2018 was held at the Nihon Ki-in in Ichigaya, Tokyo, on March 4. This is a knockout tournament, with 16 pairs competing. Reaching the final were the Kato Keiko 6P/Iyama Yuta 9P pair and the Suzuki Ayumi 7 P/Ko Iso 9P pair. The latter drew black in the nigiri, but lost a game full of hectic fighting. They resigned after 218 moves.

Tomorrow: Iyama wins first Judan game; 73rd Honinbo League; 43rd Meijin League

Redmond Reviews: Michael Redmond 9P vs Rin Kaiho 9P

Monday March 12, 2018

As a young player, Michael Redmond was in the legendary Rin Kaiho’s study group –where Rin’s wife served them all a meal 2018.03.11_redmond-rin-goseibefore they commenced playing go –) but in this week’s video game commentary, Redmond faces Rin in a Gosei tournament game, Redmond’s first tournament game of the year. “It was an unusual chance to get to play against such a famous player so early,” says Redmond, “and very special, as well.” Chris Garlock of the AGA E-Journal hosts; click here for the video.

“It’s amazing how one small mistake in midgame can make the difference between a white collapse and white advantage,” says Keldor314. “Go is just scary that way.”

“Another great review, thanks,” says Ewen Pearson. “Just joined the AGA. Are there SGFs for all of Michael Redmond’s reviews on usgo.org? If so where are they?” Click here for all the Redmond Reviews.

AlphaGo Zero vs. Master; Game 7: The magic show

Monday March 5, 2018

AG Zero comes up with a new variation to handle Master’s shimari, “and then there’s a bit of a magic show, in which Zero does 2018.03.02_Zero-Master_007all sorts of stuff inside Master’s moyo,” says Michael Redmond 9P in his commentary. “It’s pretty hard to believe.”

“The relaxed and fun atmosphere (Redmond and Garlock) have when doing these reviews is great,” says Rory Mitchell. “It keeps things light amidst all the intense thinking required, and ultimately makes these videos very rewatchable.” Adds GerSHAK, “Absolutely BEAUTIFUL game to watch. Loved the post-game summary of white’s most exciting moves, too.”

AlphaGo Zero vs. Master; Game 6: Don’t worry, play tenuki

Sunday February 25, 2018

AG Zero is back, this time “with a big group that looks like it’s about to die, just floating around in the middle of Master’s moyo”2018.02.25_AG-Zero-Master6 says Michael Redmond 9P in his commentary. “But Zero doesn’t seem to be worried, because it plays away and does all sorts of stuff.”

“Master vs Zero with Zero on black are especially great games,” enthuses viewer Stefan Kaitschick. “Master getting beaten with the common sense moves, while Zero does what it pleases, is something of a horror show.” Adds agazmenlyfzsys, “Alphago zero is just from another dimension.”

The Power Report (3): Meijin League; Marriage between go players; Kido Prizes; Iyama wins Shusai Prize; Promotions

Wednesday February 21, 2018

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

Meijin League: 
The first game in the third round of the 43rd Meijin League was played on February 1. Yo Seiki 7P (W) beat Takao Shinji 9P. Astonishingly, Yo has beaten Takao ten times to just one loss. With the third round almost completed, the only undefeated players are Cho U 9P and Shibano Toramaru; both of them have already had a bye, so their scores are 2-0. Recent results follow.
(Jan. 25) Cho U 9P (B) beat Yamashita Keigo by resig.
(Feb. 1) Yo Seiki (W) beat Takao Shinji by resig.
(Feb. 8) Hane Naoki 9P (B) beat Kono Rin 9P by resig.
(Feb. 15) Shibano Toramaru (W) beat Yamashita by 2.5 points.

Marriage between go players: Go Weekly reported that Mannami Nao 3P (age 32) married Ida Atsushi 8P (age 23) on February 12. Ida is a member of the Nagoya branch of the Nihon Ki-in; Mannami is going to move to Nagoya. Mannami said: “I want to support Ida 8-dan and look after our household.” It seems she plans to follow the lead of Kobayashi Izumi in subordinating her own career to her husband’s. In her case, it may involve some financial loss, as in recent years she has been the most popular woman professional for commentating jobs etc. at go events.

Kido Prizes: The 51st Kido Prizes were announced in the latest issue of Go Weekly. Winners were as follows:
Most Outstanding Player: Iyama Yuta
Outstanding Player: Ichiriki Ryo
New Stars: Mutsuura Yuta (for winning the Agon Kiriyama Cup), Shibano Toramaru (for winning the Ryusei title)
Woman’s Prize: Fujisawa Rina
International Prize: Iyama Yuta
Most wins: Shibano Toramaru (53)
Best winning percentage: Kyo Kagen 7P (80.3%)
Most successive wins: Iyama Yuta, Shibano Toramaru: 16
Most games played: Shibano Toramaru
The most interesting point here is the appearance of three women in the top ten (five in the top 20, 11 in the top 52). In part, this reflects the fact that players like Xie Yimin and Fujisawa Rina do fairly well against male players, but another factor is the increase in the number of women’s titles. This has also led to a big increase in the prize money available (see list below): the two newest women’s tournaments, the Hollyhock Cup, previously known as the Aizu Central Hospital Cup, and the Senko Cup actually having the most prize money. The former, which has completed four terms, is worth 7,000,000 yen to the winner, and the latter, held twice so far, is worth 8,000,000 yen.

Here are some statistics for 2017.
Most wins

  1. Shibano Toramaru: 53 wins, 13 losses
  2. Kyo Kagen: 45-11
  3. Ichiriki Ryo: 44-20

  5. (Ms) Fujisawa Rina: 40-23
  6. Shida Tatsuya 7P: 38-11; Mutsuura Yuta 7P: 38-12
  7. Motoki Katsuya 8P: 36-14
  8. (Ms) Xie Yimin: 34-22

  11. (Ms) Nyu Eiko: 27-23

Best winning percentage

  1. Kyo Kagen: 80.36%
  2. Shibano Toramaru: 80.3%
  3. Iyama Yuta: 77.78%

Most successive wins

  1. Iyama Yuta, Shibano Toramaru: 16
  2. Takei Takashi 7P, Mutsuura Yuta: 13

Most prize money won

  1. Iyama Yuta: \159,814,000 (about $1,480,000)
  2. Ichiriki Ryo: \25,237,300
  3. Takao Shinji: \24,595,000
  4. Fujisawa Rina: \24,049,700
  5. Yamashita Keigo: \21,807,300
  6. Kono Rin: \21,713,400
  7. Motoki Katsuya: \20,977,400

  9. Shiba Toramaru: \18,908,700
  10. Mutsuura Yuta: \16,996,200

Iyama wins Shusai Prize: The 55th Shusai Prize, which honors the outstanding player of the previous year, was awarded to Iyama Yuta. This prize usually goes to the player who wins the top Kido prize; Iyama has received it six times in a row (matching the record of Kobayashi Koichi) and seven times overall (behind Cho Chikun’s nine).
