The Empty Board: Philosophical Reflections on Go #15

Friday June 26, 2020

By William Cobb

I was chatting with the young man to whom I am teaching go the other day and I remarked that he was beginning to make a lot more plays that were like those of a real go player. His reply was that that might be true but in fact he felt like most of the time he had no idea what was going on.  It struck me immediately that I feel that way a lot of the time also. Moreover, often when I did think I knew what was going on I was mistaken. This feeling of being caught up in a rapidly shifting and somewhat puzzling situation is an inescapable characteristic of the game of go. This, of course, is another of the many ways in which playing go is like living life. Hopefully, with time and experience you begin to get some idea of what is going on in life. You recognize more of the actual opportunities facing you and you get a more realistic idea of what you are likely to be able to do in particular situations. Plus you also develop a better sense of what to expect from others.

Lately we’ve all been dealing with a host of realities we had not really been expecting though we knew such things were possible. It is very frustrating, not unlike playing an even game against a player who is much stronger than you. The new restrictions on living are too much like being told you can play a game of go but you have to hold the stones two inches above the board, drop them, and not move them afterwards. It would be hard to enjoy playing that way just as it is hard to enjoying living the way we have to now. Actually, the present situation has made playing go seem more like a very orderly activity—certainly one that involves virtually no frustrations. The lack of clarity about what is really going on in a game is now rather comforting in comparison with just living life.

50 years aGO — June 1970

Thursday June 25, 2020

Keith Arnold, hka, with Patrick Bannister

On June 4 the Nihon Kiin Igo Festival was held.  There were a variety of events, but the greatest excitement was created by the 2nd place finish in the All-Japan Ladies Amateur Championship of an 11-year-old prodigy, Ashida Isoko (pictured)  She would enter the pro ranks in 1975. Today she’s a 6d player with Kansai Ki’in. Her biggest tournament victory so far was taking 1st place in the Kakusei in 1985.

On June 9, veteran player Hashimoto Utaro completed his victory in the Asahi Pro Best Ten (picture) with three straight wins over Kato Masao. (game records: Game 1; Game 2; Game 3).  He held off other young players – Rin Kaiho, Ishida Yoshio and Otake Hideo in the course of this triumph.

Go Review reports that William Pinckard returned to Japan and was furthering his go studies at Iwamoto’s Go Salon and had achieved 2 dan.

Finally, on June 14, the North American Honinbo match was held via telephone.  New York’s Takao Matsuda turned back the challenge of the West Coast’s Shigeo Matsubara.

The Power Report: Korea dominates opening rounds of 25th LG Cup; Iyama makes good start Honinbo defence; Iyama leads Meijin League; Kisei S League starts

Monday June 22, 2020

by John Power, Japan correspondent for the E-Journal

Korea dominates opening rounds of 25th LG Cup

After a gap of two months caused by the shutdown to stop the spread of the coronavirus Covid-19, professional go activity resumed in Japan in June with the holding of two major events. On June 1, the 25th LG Cup King of Go, a Korean-sponsored international tournament, started its opening round. With international travel restrictions still in effect throughout north Asia, the games were played on the Net. Moreover, the 16 games were spread over three days, presumably to ensure there was no overcrowding in the local venues. This year Korean players did well in the international qualifying tournament, also held on the Net, so half of the 32 players in the first round were Korean. They were joined by nine players from China, five from Japan, and two from Chinese Taipei. Each game featured a Korean player. With 18 players last year, China scored ten wins in the first round; with two fewer players, Korea did almost as well this year, winning nine games. Japan had two more players than last year, thanks to Son Makoto and Onishi Ryuhei winning seats in the qualifying tournament, but, like Chinese Taipei, were unable to pick up a win. Onishi came closest, losing by just half a point. As an elementary-school pupil, Onishi spent some time studying in a Korean dojo, and he remembered that his opponent, Lee Taehyun, often reviewed his games for him.

   In the second round, Korea won six games to China’s two, but one of the Chinese wins went to Ke Jie, so Korea won’t be counting its chickens just yet. The next round will be played in November.

   Games were played at the headquarters of the respective go associations. Players were spread out to maintain social distancing and there were extra cameras, so that the opposing countries could monitor the playing room. With no opponent on the other side of the go board, players were able to dispense with their masks. The time allowance is three hours each, followed by byo-yomi of 45 seconds x five times. Komi is 6.5. There is no break for lunch.

Round 1

(June 1)  Byun Sangil 9P (Korea) (W) beat Murakawa Daisuke 9P (Japan) by resig.; Kang Dongyun 9P (Korea) (W) beat Kyo Kagen 8P (Japan) by resig.; Park Junghwan 9P (Korea) (W) beat Ichiriki Ryo 8P (Japan) by resig.; Lee Donghoon 9P (Korea) (B) beat Son Makoto 7P (Japan) by resig.; Lee Taehyun 7P (Korea) (B) beat Onishi Ryuhei 5P (Japan) by half a point; Shin Minjoon 9P (Korea) (B) beat Wang Yuanjun 9P (Chinese Taipei) by resig.

(June 2) Tang Weixing 9P (China) (B) beat Kim Jiseok 9P (Korea) by resig.; Lian Xiao 9P (China) (B) beat Lee Younggu 9P (Korea) by resig.; Yang Dingxin 9P  (China) (B) beat Seol Hyunjoon 5P (Korea) by resig.; Ke Jie 9P (China) (B) beat Park Kunho 4P (Korea) by resig.; Hong Kipyo 8P (Korea) (B) beat Li Xuanhao 5P by resig.

(June 3) Zhao Chenyu 8P (B) beat Choi Jeong 9P (Korea) by resig.; Ding Hao 5P (China) (W) beat Park Seunghwa 8P (Korea) by resig.; Shin Jinseo 9P (Korea) (W) beat Fan Yunro 8P (China) by resig.; Gu Jihao 9P (China) (W) beat Kim Sanghyun 2P (Korea) by 4.5 points.

Round 2 (June 5, 8)

(June 5) Kang (W) beat Tang by resig.; Lee (B) beat Lian by resig.; Shin Minjoon (B) beat Ding by resig.; Yang (W) beat Lee by resig.

(June 8) Ke (W) beat Shin Jinseo by resig.; Park (W) beat Hong by resig.; Byun (W) beat Zhao by resig.; Weon (W) beat Gu by 1.5 points. 

Taking Shibano’s temperature

   If official go activity as such in Japan resumed on June 1 with the LG Cup Net games, the first pre-virus old-style face-to-face game was played on June 2 and 3. This was the first game of the 75th Honinbo title match and, despite fears about too many unplayed title games piling up, it was only a couple of weeks behind schedule. It was held, as originally planned, at the Tokiwa Hotel in Kofu City, Yamanashi Prefecture, but minus all the “trimmings.” Usually securing a title-match game is a coup for a provincial city or town, and the local dignitaries and notable go players do their best to make a big occasion of it. They stage an elaborate welcome party for the players and their large “entourage” of go officials and reporters and also hold side events, such as tournaments for children, public commentaries on the title game, and sightseeing for the players. None of that took place this time, but at least the face-to-face game got played, though everyone wore masks and had their temperatures checked. 

Iyama makes good start Honinbo defence

   Shibano drew black in the nigiri, but the game was dominated by Iyama. He showed excellent judgment in deciding that he could afford to sacrifice a large group. Shibano resigned after 182 moves.

   The second game was originally scheduled to be held in the Kokura Castle Garden in Kita-Kyushu City, but it was switched to the Nihon Ki-in in Tokyo (I haven’t seen an explanation of the reason). It was played on June 13 and 14; taking black, Iyama won by resignation after 143 moves.

   The third game will be played at the Takarazuka Hotel in Takarazuka City on June 22 and 23.

Iyama leads Meijin League

   Iyama Yuta and Shibano Toramaru have just started their first best-of-seven title match, but the chances look good there will a second one in the autumn, as Iyama, on 5-0, has kept his sole lead in the 45th Meijin League. At present, the main threat to him would seem to be Ichiriki Ryo 8P, the only player with only one loss. However, he still has four games to go and his loss was to Iyama, so he will need outside help to catch up. Incidentally, after losing every game in the Honinbo League, Yamashita finally picked up his first win in the Meijin League. Results since my last report follow. 

(June 4) Hane Naoki Gosei (W) beat Rin Kanketsu 8P by 5.5 points. 

(June 8) Yamashita Keigo 9P (W) beat Cho U 9P by 11.5 points; Iyama Yuta Kisei (W) beat Hane by resig.

(June 11) Kono Rin 9P (W) beat Kyo Kagen 8P by half a point. 

Kisei S League starts   

   The first game in the 45th Kisei S League was played on June 11. It was between the players promoted from the 44th A League. Ichiriki Ryo (W) beat Cho U by resig.

Retirement

Sanno Hirotaka 9P retired as of May 29. He was born on May 29, 1940 in Hiroshima Prefecture. In 1952, he became a disciple of Segoe Kensaku, Hon. 9P. He made 1-dan in 1957 and reached 9-dan in 1979. He reached the landmark of 500 wins in 2006. He made instruction tours of Europe and the US in 1964. He is a fan of Shusaku and contributed a number of game commentaries to “Invincible.”

Tonight: Redmond on Mutsuura Yuta 7P vs Iyama Yuta Kisei, Honinbo, Tengen (9P)

Sunday June 14, 2020

Tune in to the AGA’s Twitch channel at 8p tonight for Michael Redmond 9Ps live commentary on the “Golden Panda Cup” tournament game between Mutsuura Yuta 7P and Iyama Yuta Kisei, Honinbo, Tengen (9P). Hosted by Pandanet, the tournament setup is similar to Nongshim in that there are three teams of five players, and player 1 from team A plays team B, winner plays team C, etc. with the winning player continuing into the next round and losing teams supplying the next player. Mutsuura was a player in the Shibano (Meijin, Oza) team and Iyama was the captain of the Iyama team. This was game 5 of the tournament, and Mutsuura 7P already had 3 wins. He took out former Gosei Kyo Kagen in round 2, and continued to beat Xie Imin and Fujisawa Rina in 3rd and 4th rounds. The Iyama and Ichiriki teams had lost two players each while the Shibano team was untouched. “The Iyama team apparently figured they needed their top player to stop Mutsuura and maybe hoped Iyama could take it away from there,” says Redmond. After winning this game Mutuura was the MVP, called the Golden Panda in this tournament.

Redmond launches new AlphaGo video commentary series

Monday June 8, 2020

In the first days of 2017, rumors started to ricochet around the online go community. A mysterious online player had been making huge waves by defeating dozens of top professionals on go sites in Asia in recent days. “Master” first appeared on December 29, 2016, registering from Korea. Achieving 30 consecutive wins against many former and current world go champions, Master defeated Park Junghwan four times and Ke Jie twice. After that, Master appeared on a different go site and logged another 30 consecutive wins. That made it 60 games in a row with no losses. Was AlphaGo the Master?

Michael Redmond had been on holiday when the games were being played but word had of course spread swiftly through the professional community about the mysterious online player racking up win after win. “That kind of record was simply mindblowing,” he says, “and even before I got the game files off the internet it was clear that something new was happening. Anyone – or anything – that could win 60 straight games could probably give a 2-stone handicap, and these were top professionals who were losing to a player no-one had ever heard of.” The 60 Master games were not only evidence that AlphaGo had attained a whole new level of play, but an incredibly rich “treasure trove for professionals,” says Redmond.

Working again with American Go E-Journal Managing Editor Chris Garlock, Redmond is launching a new series of videos in which he’ll focus on the key points of each of the 60 Master games in brief videos, most of which will be 15 minutes or less. The commentaries will also be the basis for Volume 2 of AlphaGo to Zero: The Complete Games, “as well as a chance to introduce viewers to the professional go players who tackled Master,” notes Garlock.

The first video will be released on Tuesday, June 9 on Redmond’s YouTube channel and the series will be linked on the AGA’s YouTube channel  as well. Stephen Hu is producing the series.

The human player in this first game is 15-year-old Pan Tingyu 1P, who finished #1 in the Chinese professional qualification tournament in 2015. Pan has Black and plays a modern version of the mini-Chinese, and AlphaGo shows a new move in the upper left corner, which has since become the standard move for White in the Chinese opening pattern.

NOTE: The AlphaGo vs AlphaGo series, now up to Game 41, will continue through Game 55.

50 years aGO – May 1970

Saturday May 30, 2020

by Keith L. Arnold, hka, with Patrick Bannister

May was dominated by Rin Kaiho’s defense of the Honinbo Title against challenger Sakata Eio. Already down a game, Sakata lost a bitter half pointer in the second game (top right) on May 7-8.

Those of you fortunate enough to travel (travel, I remember travel) to Japan will recognize this drawing (top left) – on May 8 the Nihon Kiin unveiled the plans for its “new” headquarters.

In the middle of the month Rin and Sakata squared off again (bottom right), and with a third straight loss on May 15-16, Sakata’s back was against the wall.

As of May 21, Fujisawa Shuko was leading the Meijin League (bottom left), with a 4-1 record, thanks to Takagawa Kaku’s victory over Kajiwara Takeo, giving them both matching 4-2 records.

Finally, the May 27 game brought the swiftest of ends to Sakata’s Honinbo challenge, losing in four straight games.

AlphaGo vs. AlphaGo; Game 41: Michael’s mom and some exciting fighting

Friday May 29, 2020

Michael Redmond 9p, hosted by the AGA E-Journal’s Chris Garlock, reviews the 41st game of the amazing AlphaGo vs. AlphaGo selfplay games. The 50-game series was published by Deepmind after AlphaGo’s victory over world champion Ke Jie 9p in May 2017.

In this commentary, originally broadcast live on the AGA’s Twitch channel on April 26, Redmond talks about a special video his mother made about the first time a young Michael met Kaoru Iwamoto, “who did so much to promote go overseas.” Today’s game starts with the Chinese Opening, “which is a little unusual for AI’s, we’ll see a few 3-3 invasions and of course some exciting fighting involving some groups where you’ll be wondering if they’re dead or alive.”

Also, tune in this Sunday on Twitch at 7p EDT for another live commentary, this one on the Ichiriki-Shibano game from Pandanet’s recent “Golden Panda Cup”

The Power Report: Professional go to resume & more reports

Thursday May 28, 2020

by John Power, Japan correspondent for the E-Journal

Professional go to resume

When the Japanese government declared an emergency on April 7, the Nihon Ki-in and the Kansai Ki-in fell in line and cancelled face-to-face go activity. The emergency was lifted on May 25, and on the same day the Nihon Ki-in announced that it would resume tournament activity on June 1, as will the Kansai Ki-in. However, some precautions will be observed.

  1. The temperatures of players will be measured.
  2. Players will wear masks.
  3. Attention will be paid to air circulation.
  4. There will be a limit to the number of games being played so that venues don’t become overcrowded. First of all, the first round of an international tournament, the 25th LG Cup, will be played on the net on June 1. The Japanese participants will play their games at the Nihon Ki-in Two domestic title matches were affected by the shut-down. The first game of the 75th Honinbo title match will be played in Kofu City, Yamanashi Prefecture, on June 2 and 3. Shibano Toramaru Meijin will be challenging Iyama Yuta Honinbo. Games 3 to 5 from the 58th Judan tournament which is being fought between Murakawa Daisuke Judan and Shibano Toramaru, have been rescheduled for June 17 and June 26 at the Nihon Ki-in and, if the match goes the full distance, July 3 at the Kansai Ki-in. The match is tied 1-1.

Tong wins Net tournament

On February 19, I published a report on a new net tournament, the 1st Wild Fox Contest for Supremacy, in which Iyama Yuta had won his way to the final and made a good start, winning the first game by half a point with white. However, in the second, his opponent, Tong Mengcheng 8P, returned the courtesy, winning by the same margin. The game was played on April 14. In the third game, played on April 22, Tong drew black and won by 3.5 points. First prize was 500,000 yuan (about $70,000). About 59,000 spectators followed the final game. Iyama had to be content with second place, but this is the best result a Japanese representative has scored recently. His cumulative score against eight Chinese opponents was 9-2. (Note: in English, the server seems to be called just “Fox.”)

Ohashi wins first tournament

The Young Bamboo Cup is a small-scale tournament for players 40 and under at the Kansai Headquarters of the Nihon Ki-in. The tournament is open to 16 players, which comes close to matching the number of players at this branch who meet the age condition. If there are more than 16 applicants, preliminaries are held; if fewer, the organizers can nominate extra players. The tournament was founded in 2018, but has already concluded its fourth term. The semifinals and final were held on April 7. In one semifinal, Ohashi Naruya 7P beat Utani Shunta 2P; in the other, Muramoto Wataru 2P beat Otani Naoki 3P. In the final, Ohashi (B) beat Muramoto by 9.5 points. First prize is 200,000 yen (about $18,570), and second is 100,000 yen. This is admittedly a minor title, but the 29-year-old Ohashi was very happy to win it. He commented: “This is my first victory. I hadn’t received any trophies since becoming a professional, so I’m extremely happy. Other tournaments have been postponed for the time being because of the corona virus, but I’ll be able to hole up at home cheerfully. Don’t tell anyone, but I was so excited after the win that I couldn’t sleep until the morning.”

Onishi and Son qualify for LG Cup

As mentioned in a previous report, the organizers of the 25th LG Cup cancelled the international qualifying tournament scheduled to be held in Seoul in April and instead allocated seats to the different professional organizations to use as they wished. Japan has three seeded places, taken by Murakawa Daisuke Judan, Ichiriki Ryo 8P and Kyo Kagen 8P, and was allotted two more places. These were decided by a net tournament among eight young players held on April 6 and 7. Onishi Ryuhei 5P won one side of the mini-tournament and Son Makoto 7P the other. They will play their first-round games at the Nihon Ki-in on June 1.

Ichiriki eliminated from MLily Cup

The quarterfinals of the 4th MLily Cup were held on the net, the first time ever for a major international tournament, on April 27. Ichiriki Ryo 8P was the only player standing in the way of complete Chinese domination of this Chinese-sponsored tournament, but his winning run came to an end in this round. Taking white, Xie Ke 8P beat him by resignation. Even so, this was Ichiriki’s best result so far in a major. Other results follow (full details are not available): Mi Yuting 9P beat Xie Erhao 9P; Ke Jie 9P beat Fan Tingyu 9P; Xu Jiayang 8P beat Meng Tailing 7P.

Go players marry

There is yet another professional couple. On February 10, O Keii 3P, the daughter of O Rissei, former Kisei, and Yamamori Tadanao 7P tied the knot. They are both members of the Nagoya branch of the Nihon Ki-in.

Retirements

Ezura Yuichi retired as of April 30. Born on January 15, 1943 in Tokyo, he became 1-dan in 1962 and reached 8-dan in 1995. On his retirement, he was promoted to 9-dan.

Aragaki Takeshi retired on the same date. Born in Okinawa on June 4, 1956, he became a disciple of Sakata Eio and qualified as professional 1-dan at the Tokyo Nihon Ki-in in 1971. He reached 9-dan in 1994.

Obituary: Honda Sachiko

Honda Sachiko 7P died of old age on May 1. Born on December 30, 1930, she was 89. She was the middle one of the famous three Honda sisters, her older sister being Sugiuchi Kazuko (born on March 6, 1927, and still active) and her younger sister Kusunoki Teruko 8P (born on September 3, 1939; retired in 2019). Honda was born in Shizuoka Prefecture. She became a disciple of Kitani Minoru 9P and made 1-dan in 1947. She was promoted to 6-dan in 1981 and retired in 2000, and was then promoted to 7-dan. She won the Women’s Championship five times and the Women’s Honinbo title twice. In 1961, she made a two-month instruction tour of the U.S. along with her sister Teruko and Kitani Reiko, and in 1974 toured Europe with Kobayashi Chizu. As one of three go-playing sisters, it seems apposite that she took the three Mukai sisters–Mimura Kaori 3P (born in 1981, wife of Mimura Tomoyasu 9P), Nagashima Kozue 2P (born in 1984; not married to a professional), and Chiaki 5P (born in 1987, wife of Sugimoto Akira 8P, but she plays under her maiden name)—as disciples.
