The Power Report (2/2): Kisei Leagues; Tournament to decide the Kisei challenger; 74th Honinbo League seats; Yamashita-Iyama pairing in Tengen sets new record

Monday September 24, 2018

by John Power, Japan correspondent for the E-Journal

Kisei Leagues2018.09.24-kisei-league

S League: Below are the results of the games played in the final round of the 43rdKisei S League. On September 13, Takao Shinji 9P (B) beat Yamashita Keigo 9P by half a point. On September 17, Ichiriki Ryo 8P beat Kyo Kagen Gosei by resig. and Kono Rin 9P (B) beat Cho U 9P by 1.5 points. Yamashita had already clinched victory in the league in the fourth round, so this loss did not hurt him. However, Kyo Kagen’s loss was painful, as it meant ceding second place to Kono. There are no play-offs in the Kisei leagues: ranking takes precedence, so Kono qualifies for the final stage (see below). The bottom two players will drop to the A League.

A League: Murakawa Daisuke 8P took first place in the A League, which has eight members. Actually, he “tied” with three other players on 5-2—they were So Yokoku 9P, Yo Seiki 7P, and Shida Tatsuya 7P—but his number one ranking gave him precedence. Murakawa and Yo will be promoted to the S League in the next term (assuming the former does not become Kisei).

B Leagues: There are two B Leagues, each with eight members. A play-off was held on September 17, and Shibano Toramaru 7P (B2 winner on 7-0) (W) beat Akiyama Jiro 9P (B1 winner on 5-2) by resig.

C League: The C League is like a tournament in its own right: it has 32 players and is run by the Swiss System. Onishi Ryohei 3P won it 5-0.

Tournament to decide the Kisei challenger: The league winners above will participate in an irregular knock-out tournament to decide the challenger to Iyama Yuta. It works as follows: Onishi plays Shibano, the winner plays Murakawa, the winner plays Kono, and the winner plays Yamashita. The final with Yamashita is a “best-of-three” in which three games will never be played. The reason is that Yamashita will start off with a one-win advantage, so his opponent has to win two in a row. Otherwise, what would be the point of winning the top League? In theory, though, any of the 62 players in any of the five leagues could become Kisei, so it’s thought that professionals feel more incentive than with the former system.

74th Honinbo League seats: Three of the four vacant seats in the 74th Honinbo League were decided on September 6. Anzai Nobuaki 7P (W) beat O Rissei 9P by half a point; Anzai will make his debut in a league. Hane Naoki 9P (B) beat Takao Shinji 9P by 3.5 points; he makes an immediate comeback after dropping out of the previous league. Ichiriki Ryo 8P (W) beat Sakai Hideyuki 8P by resig.; he also played in the 71stLeague. The final play-off was held on September 10. Kono Rin (B) beat Mutsuura Yuta 7P by resig.; like Ichiriki, Kono last played in the 71stLeague. These players will join Yamashita Keigo 9P

Yamashita-Iyama pairing in Tengen sets new record: In my previous report, I noted that Yamashita Keigo had become the challenger to Iyama Yuta for the Tengen title. Subsequently, Go Weekly pointed out that this will be the 11th title match between these two, which sets a new record. So far, Iyama has lost only once. The previous record was ten, shared among three players in two pairings: Cho Chikun (eight wins) v. Kobayashi Koichi and Kobayashi Koichi (six) v. Kato Masao. Next is the current Meijin title match, which is the ninth match between Iyama (six) and Cho U. Equal fourth is Cho Chikun (seven) v. Otake Hideo.

The Power Report (1 of 2): Iyama makes best 16 in Samsung Cup; Iyama takes two-game lead in Meijin; Ichiriki to challenge for Oza title

Saturday September 22, 2018

by John Power, Japan correspondent for the E-Journal2018.09.22_Samsung Iyama

Iyama makes best 16 in Samsung Cup:
The opening round in the 2018 Samsung Cup was held at the Samsung Insurance Campus in Korea on September 4 to 6. (It’s the 23rd cup, but apparently the sponsor is not numbering them that way any more; the full title of the tournament goes Samsung Fire & Marine Insurance World Masters 2018.09.22_Samsung left Shibano right ChenBaduk 2018.) The first round is like a tournament in its own right: the 32 players are split up into eight groups of four, who then play each other. Two wins take you to the next round (whether your score is 2-0 or 2-1) and two losses (0-2 or 1-2) eliminate you.
Japan was represented by Iyama Yuta 9P (right), Shibano Toramaru 7P (left), and Ryu Shikun 9P (right, below). The first two were Japan’s seeded players; Ryu won a seat in the Seniors division of the international qualifying tournament and was playing in the main tournament for the first time since 2001.2018.09.22_Samsung  Ryu right
In the first game (September 4), Shibano was the only one to pick up a win. He defeated Chen Yaoye 9P of China, who eliminated him from the Bailing Cup (see my previous report). Shibano had white and won by 4.5 points. Iyama Yuta (W) lost to Tang Weixing 9P (China) by resig. and Ryu (W) lost to Li Xiangu 5P (China) by 1.5 points. In the 2018.09.22_Samsung Yun Iyamasecond game, played the next day, Iyama (W) beat Yun Seongshik (left, below), an amateur player from Korea, by resig.; Ryu (B) beat Wu Guangya 6P (China) by resig.; Park Junghwan 9P (Korea) (B) beat Shibano by resig. In the third game (the 6th), Iyama (B) beat Tan Shui 9P (China) by resig.; Gu Zihao 9P (China) (W) beat Shibano by resig.; Li Xiangu (B) beat Ryu by 1.5 points.
Iyama was the only one to make it to the second round, but Shibano and Ryu were by no means disgraced, as scoring even one win at this level is impressive. Actually, Shibano was in what was dubbed the “group of death,” as the other three players (Park, Gu, and Chen) are all past or present world titleholders. Ryu, who at the “advanced” age of 46 qualifies as a senior, was ahead in his third game, but slipped up in the endgame. He was chagrinned to lose twice to the same opponent by the same small margin.
The second round will be played on October 1.2018.09.22_43meijin2_Iyama

Iyama takes two-game lead in Meijin: The second game of the 43rd Meijin title match was held at the Kakujoro a traditional inn, in Tahara City, Aichi Prefecture, on September 12 and 13. Cho U, the challenger, is know for his skill at fighting kos and he seemed to take the initiative when he connected a ko in the first fight on move 55. However, there was a lot of action still to come: the game extended to 336 moves, making it the second-longest game in a Meijin title match. Both sides made mistakes or errors in judgment, so the lead shifted back and forth. The game was decided when Cho suffered a hallucination on move 253. This was decisive. Iyama (right) won the game by 2.5 points. Iyama: “The result of the ko fight at the beginning was not favorable for me. I thought it would be a drawn-out game, but I was not confident. I didn’t have a clue about some of the things going on and thought I had messed up the game, but I took profit with border moves in the middle game.” Cho: “There were many positions in which I thought the game was easier for me. I got my last chance in the endgame, but I hallucinated and lost about three points. The content was not bad for me, so I will make a fresh start and do my best.” The third game will be played on September 25 and 26.

Ichiriki to challenge for Oza title: The play-off to decide the challenger for the 66thOza title was held at the Nihon Ki-in in Tokyo on September 13. It was fought between two players younger than the title-holder Iyama Yuta: Ichiriki Ryo 7P (aged 20) and Motoki Katsuya 8P (aged 23). Taking black, Ichiriki won by resignation after 239 moves. He will make his second successive challenge for this title and his fifth challenge overall to Iyama. The first game will be played on October 26.

Your Move/Readers Write: The Eistellung Effect

Saturday September 22, 2018

“In response to Bill Cobb’s message of the importance to play moves out of our comfort zone (The Empty Board: Philosophical Reflections on Go #10 9/19 EJ),” writes Eric Osman, “I offer the following: A 7d player on kgs alerted me to the concept of Eistellung, which is the propensity we have for solving a problem in life (or on the go board) by using the methods we have learned, even though for this particular problem there’s a better way!”

Jasiek releases new book on endgame

Friday September 21, 2018

Robert Jasiek’s new book “Endgame 2 – Values” is now available. The result of two years of work and research, Jasiek says 2018.09.16_Endgame_2_Coverthe book “teaches every relevant, basic aspect of endgame evaluation systematically, clearly and in detail.” It explains modern and traditional endgame theories, the microendgame, and the impact of scoring. “We evaluate positions, follow-up positions and moves so that all their values are consistent and related,” says Jasiek. “The theory is well applicable to every endgame position and move, approximates absolute truth and is supported by many examples.” The 260-page book is available in both  printed (EUR 26.50) and PDF (EUR 13.25) formats.

Capture go app for iPhone

Thursday September 20, 2018

Image-1There is a new capture go app for Apple devices, designed for the very young.  “I created this app for my six-year-old grandson who was showing interest in my go playing, but was not yet mature enough to understand ko fights, trade-offs, and sacrifice,” says developer Tim Hoel.  The app walks users through rules and basic concepts, all with spoken narration.  Beginners can see examples of how situations play out, and then find solutions themselves. Simple lessons build from there, of which there are several, and then you can play against the computer.  It has three difficulty levels, so players can move up against the machine.  At level three, it is smart enough to occasionally catch even an experienced player.  Level one stays easy enough to keep young kids from getting frustrated.  Lessons can be reviewed at any point, and the rules are printed out in a separate tab as well. As this is capture go, and not regular go, one has to keep playing until one or more stones  are captured.  Passing is not an option, which means you will need to fill in your own eye if there are no other moves. Young players likely won’t make it to this point anytime soon, but when they do, it is arguable they are ready for full go. “Capture Go is a great way to get started because the rules are a little simpler and the goal is easy to understand, but it still teaches a lot about recognizing liberties, contact fights, forcing sequences, and planning ahead,” adds Hoel.  iPhone and iPad users can find the free app in the App Store, there is no Android version. -Paul Barchilon, EJ Youth Editor

Go Spotting: Aliens and The Artificial Human; The Wheel of Time

Thursday September 20, 2018

Aliens and The Artificial Human: “Just finished watching the final episode of Ancient Aliens Season 13, episode 13,2018.09.20 Ancient Aliens Season 13, episode 13 writes Michael Bacon. “About twenty or so minutes into the program the focus was on Alpha Go vs Lee Sedol, who was called the World Go Champion. The segment, which was a few minutes in length, then moved 2018.09.16_wheel-of-timeon to Alpha Zero.” The episode is called “The Artificial Human.”

The Wheel of Time: “Maybe it has been reported before,” writes Peter Freedman, “but, in Robert Jordan’s series ‘The Wheel of Time’, often people enjoy a ‘game of stones’, which appears to be go.”

The Empty Board: Philosophical Reflections on Go #10

Wednesday September 19, 2018

by William Cobb2018.09.16_empty-go-board-with-bowls-and-stones-water swirl

A big part of life is experiencing things you have never experienced before: flying in a plane, hiking to a mountain top, being in a snow storm, visiting a country where you don’t speak the language. We think of such things as enriching our lives, making life more interesting, and fun besides. There’s an obvious parallel to this in go: the game has a virtually infinite range of possibilities, but some players seem resistant to getting outside their already familiar circumstances. There are a lot of things that many of us have seldom if ever experienced: playing tenuki in response to an approach move in the opening, knowing what to do when the opponent attaches to a 3-4 point stone, being confident about the best way to continue after the first dozen or so moves, consistently judging the status of small groups accurately, knowing where to invade common positions, etc. In this regard, we’re like people who are perfectly happy to have never seen the ocean or a snow-capped mountain. The world is full of amazing and wonderful things; we’re happy to spend time, money, and energy exploring and becoming familiar with as many of them as we can. We should have the same attitude toward playing go. Just playing won’t get you to a lot of the amazing amount of beauty and fascination the game offers. You’ve got to get outside the familiar patterns you already know. This is why it makes no sense to refuse to read books, take lessons, or study the games of stronger players. There’s a truly amazing world out there. We need to spend some time and effort exploring it and not just stay inside the familiar area we already know. Don’t just buy books—read them. Don’t just look at the results of pro games—play through them. Don’t just play the same opening moves—try some you’ve not used before. You’ll discover that go is even more fun than you thought.
