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.
- Shibano Toramaru: 52 wins, 18 losses
- Ichiriki Ryo 8P: 47-14
- Ueno Asami, Women’s Honinbo: 44-25
- Mutsuura Yuta: 38-20; Fujisawa Rina, Women’s Hollyhock Cup: 38-28
- Otake Yu 3P: 36-12
- Kono Rin 9P: 35-18
- Iyama Yuta Kisei: 34-27

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

AlphaGo vs. AlphaGo; Game 36: The ladder game
Friday February 14, 2020
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.
