The Power Report: 2019 review

Notizie AGA - 1 ora 41 min fa

by John Power, Japan correspondent for the E-Journal

Most wins
Shibano Toramaru, the youthful new Meijin, topped this list for the third year in a row. Considering the level of his competition now, as he’s playing top-flight opponents in leagues and title matches, that’s a significant achievement and testimony to his great form for most of the year. Also significant are the two best results ever attained by female players, with Ueno Asami and Fujisawa Rina coming third and fourth respectively. In particular, their good results against male players show that the level of women’s go is steadily rising. Here are the top 12.

  1. Shibano Toramaru: 52 wins, 18 losses
  2. Ichiriki Ryo 8P: 47-14
  3. Ueno Asami, Women’s Honinbo: 44-25
  4. Mutsuura Yuta: 38-20; Fujisawa Rina, Women’s Hollyhock Cup: 38-28
  5. Otake Yu 3P: 36-12
  6. Kono Rin 9P: 35-18
  7. Iyama Yuta Kisei: 34-27
  8. Suzuki Shinji 7P: 33-15; Son Makoto 7P: 33-19
  9. Kyo Kagen 8P: 32-17
  10. Xie Yimin 6P: 31-23

Most successive wins

  1. Ichiriki Ryo, Fujita Akihiko 7P (twice): 16
  2. Kono Rin: 13
  3. Yokotsuka Riki 7P, Fujisawa Rina: 12
  4. Hane Naoki Gosei: 11
  5. Shibano Toramaru, Adachi Toshimasa 6P, Muramoto Wataru 2P (twice), Nyu Eiko 2P: 10

Best winning percentage

  1. Ichiriki: 77.05
  2. Otake Yu, Fujita Akihiko (30-10): 75
  3. Shibano Toramaru: 74.29
  4. Oomote Takuto 3P (20-7): 74.07

2019 Prize-money promotions
There are three ways to earn promotions. One is through cumulative wins, which is the slow way. The fast way is through a tournament success, which will enable a low-ranked player to skip some intervening ranks. The conditions are fairly complicated, so here is a summary. Promotion to 7-dan: challenging for one of the bottom four (Oza, Tengen, Gosei, Judan) of the top seven titles; winning the Agon Kiriyama Cup or the Ryusei tournament; winning a place in the Kisei S League or the Honinbo or Meijin League. To 8-dan: winning one of the bottom four of the top seven titles; challenging for one of the top three titles (Kisei, Meijin, Honinbo); coming second in an international tournament. To 9-dan: winning a top-three or an international title; winning one of the bottom four of the top seven titles a second time. In theory, a new 1-dan could go straight to 9-dan by this system. In practice, however, it’s unlikely because it would take close to two years to go from the first qualifying round to a top-three title match, during which time a player strong enough to do this would have already made 2-dan or 3-dan.
The third way to get promoted is by coming first or second in the prize-money list for each dan from 1-dan to 5-dan; the top 6-dan is also promoted. Only prize money won in the top seven titles is counted. These promotions take effect on January 1 and are based on the previous year. (Players who earn promotions through the cumulative-wins system are not considered.) The promotions for 2019 are given below.

To 7-dan: Adachi Toshimasa
To 6-dan: Terayama Rei, Yo Chito
To 5-dan: Onishi Ryuhei, Koike Yoshihiro
To 4-dan: Otake Yu, Hirose Yuichi
To 3-dan: Seki Kotaro, Torii Yuta
To 2-dan: Chotoku Tetsushi, Sakai Yuki

Top prize-money winners for 2019 (in yen)

  1. Iyama Yuta: 108,259,237 (about $984,000)
  2. Shibano Toramaru: 67,669,600
  3. Ichiriki Ryo: 36,847,129
  4. Cho U: 32,272,656
  5. Fujisawa Rina: 26,593,572
  6. Yamashita Keigo: 26,177,458
  7. Kono Rin: 25,230,600
  8. Hane Naoki: 21,004,400
  9. Ueno Asami: 20,777,172
  10. Kyo Kagen: 19,044,240

Why does it take so long to get a tournament rated?

by Steve Colburn
During last year’s U.S. Go Congress I heard the same question more than a few times. “Why does it take so long to get the tournament I last played in rated?” We’re always trying to get ratings updated more quickly but here’s why that’s often a challenge.

At the end of the tournament the Tournament Director (TD) sends a results file to the AGA, which processes the data. Two of the key things are active membership and game result probability.
An active AGA membership gives you many benefits, among the largest of which is being rated in our system. So the first major check is to see if all player’s AGA memberships are up to date, and expired memberships are the largest reason ratings are delayed. The AGA Membership Manager has been working very well since it was fixed in May 2019, and TDs are no longer able to submit tournament results without all players being AGA members.
The second check, which occurs less frequently but can also slow down updated ratings, is when game result probabilities are suspect, like when it’s reported that a significantly lower-ranked player defeated a stronger player. In such a case, we’ll check in with the TD to see if it’s an error, if someone just had a good — or a bad — day.

Once these two hurdles are cleared, the rest of the process moves fairly quickly and the updated ratings can be posted. Our ultimate goal is for every TD to be able to run tournaments with no issues so that we can process and post updated that same weekend.


AlphaGo vs. AlphaGo; Game 36: The ladder game

Notizie AGA - Ven, 14/02/2020 - 10:30

Chocolates and flowers are popular Valentine’s Day gifts but what go players really want is another AlphaGo game commentary and Michael Redmond 9P and Chris Garlock deliver with their latest AlphaGo vs. AlphaGo game commentary, Game 36 of the series, going up on the AGA’s YouTube Channel at noon today, a bit earlier than the usual 6p release time.

“The most interesting thing to me about this game is the way AlphaGo handles ladders,” says Redmond. “Earlier versions seemed to have some trouble with them, but not AG and in this game, AlphaGo devises some original ways to handle them.” Redmond poses a number of problems for Garlock to solve, and the Twitch audience — the commentary was originally streamed live on the AGA’s Twitch channel — gets involved.

Go and Math Academy teaches hundreds to play at Art Institute

Notizie AGA - Mar, 11/02/2020 - 23:58

On Saturday Feb 8, Xinming Simon Guo – assisted by his wife Joy – Greg Kulevich and Mark Rubenstein taught over 350 new-comers how to play Go at the Chicago Art Institute’s Lunar New Year event. This is the second year that Simon has been invited to teach Go to museum visitors. In addition to Go, the event included Chinese chess, paper cutting, taiko drumming and other activities. 

“Simon has a unique way of teaching Go which enables newcomers of all ages to start playing real Go right away, without any complicated explanations or terminology,” says Rubenstein. “I had known about his method for a long time, but hadn’t tried it myself. I used his method all day, and found that it really simplifies the game for first-timers.”  

“This unique method has been used in many math classrooms in the Chicago area, and it is compatible with different rule sets, which means there is little conflict when players visit a local club and count the score by territory,” says Guo.

Simon Guo is the founder of the Go and Math Academy, and was the AGA’s Teacher of the Year in 2015. He teaches thousands of school students to play Go every year. Visit their local wiki page to find out more information about the Go and Math Academy or check them out on Facebook.

Spindrift: Leon Chen 4P’s Original Tsumego now available on OGS

Notizie AGA - Lun, 10/02/2020 - 19:04

Need some fresh life-and-death Go problems for inspiration? Check out Spindrift: Leon Chen 4p’s Original Tsumego, featuring 136 original tsumego puzzles of various levels written in both traditional Chinese and English. It is available for purchase electronically for 10 USD, and accessible after purchase through the buyer’s OGS account. 

This is Hsi “Leon” Chen (陳禧) 4P’s first published tsumego collection of many more to come. Chen – one of Taiwan’s top professional players – has crafted thousands of puzzles and is excited to share his work with Go fans all over the world. “To me, every life-and-death puzzle is a condensed gem discovered by the tsumego creator,” says Chen, “like a precious cloud of spindrift resting on top of a reef rock. Puzzles encapsulate memories; but more importantly, they tell the stories of our times. I can’t call this a valuable gift, but it’s a little something from my heart!”

In addition to the tsumego variations, each puzzle includes a short story written by frequent E-Journal contributor Stephen Hu, who designed the cover and wrote the English language text. “Every original tsumego reminds me of a painting, a song, or perhaps a certain story,” says Hu. “It is the imagination that breaks all bounds; despite the simplicity of Go stones on the wooden board, they are capable of composing melodies that mesmerize. I just wish I could look through the artist’s kaleidoscope, and capture all the vibrance beyond the black and white.”

Interested players can order a copy today or start with a free preview of 5 puzzles.

Redmond’s Reviews, Episode 19: Michael Redmond 9P vs Kudo Norio 9P

Notizie AGA - Sab, 08/02/2020 - 00:00

Michael Redmond 9P and Chris Garlock return with their latest Redmond’s Review, Episode 19, posted on the AGA’s YouTube Channel.

Kudo is a seasoned 9-dan professional in his late 70s. Though not as well-known in the West as some other players, he’s posted good records throughout his career and was a contender for titles from the 1970s through the 1990s, including taking the Oza from Cho Chikun and the Tengen from Rin Kaiho. “He’s a very steady player,” says Redmond. “As a younger player he had an attacking style, and doesn’t bother so much about territory. Still what you might call a very thick player, he likes to build strong positions and doesn’t like to be under attack. He’s got a well-balanced game with a solid opening. And interestingly for a player of his age, he’s been integrating a lot of AI stuff too.” Redmond also discusses how he prepares for matches like these, although he warns viewers at the outset that “This is not a well-played game on my part, so you can probably learn more” from his opponent’s play.

The commentary was originally streamed live on Twitch, which gave viewers a chance to interact with Redmond and Garlock, who will be live-streaming more game commentaries in the weeks ahead on the AGA’s Twitch channel, which you can follow to get notified of live streams.

Video produced by Stephen Hu, Allen Moy, Chris Garlock and Andrew Jackson.
