Sunday Problem #15
This problem is from a classic tsumego collection by Hon’inbō Shūsai called 死活妙機 or Shikatsu Myōki. This name is notoriously difficult to translate into English: while shikatsu means life-and-death, myōki is a Buddhist term referring to excellent adhering to Buddhist teachings. Presumably this is meant in the sense that ‘if you manage to solve all these problems, your reading will …
Sunday Problem #14
This problem is from my recent teaching game against Daniel Hu 5d in the bga Strong Player Development Programme. A review of the teaching game can be watched here.
Black to play.
Solution
Black’s hane of combined with the placement of 3 is a strong combination – however, Black has to be wary of White’s resistance …
Sunday Problem #13
This problem is from the Japanese tsumego collection, 秀行創作詰碁傑作集 or ‘Collection of Shūkō’s tsumego masterpieces’ by Fujisawa Hideyuki (whose first name can also be read as ‘Shūkō’).
I have received some feedback that the Sunday problems have been too difficult, so this week I tried to pick a slightly easier problem. Still, in my opinion it is not fun if …
Sunday Problem #12
This problem is from another of my favorite tsumego collections, 傑作詰碁辞典 or ‘Collection of tsumego masterpieces’ by Sekiyama Riichi, Sekiyama Toshio, and Sekiyama Toshimichi.
Sekiyama Riichi is famous for winning the first Hon’inbō tournament in 1941; Sekiyama Toshio is his son; and Sekiyama Toshimichi is Toshio’s son. As a fun trivia, the ‘Ri’ in Riichi is written with the same …
Sunday Problem #11
This is a slightly modified version of a problem that came up in the league game between bellicose and yosai.
Black to play.
Solution
Black 1 is the key point. White 2 is forced, but Black can then form the necessary eye space with the descent of 3. After 4–5, white 2 is captured in an oiotoshi, …
Sunday Problem #9
Like Sunday Problem #8, this is also from Guanzi Pu.
Black to play.
Solution
Black’s 2-1 placement of 1 is the key to solving this problem. 2–6 are White’s correct resistance, and the result is a kō for White’s life.
If Black starts with the hane of 1, white 2 lives unconditionally.
Sunday Problem #8
This problem is from Guanzi Pu – possibly my favourite of the classic problem collections thanks to its varied and relatively difficult problems.
While a (most likely illegal) pdf version of the book been posted around on Western go websites, its solutions often seem to be wrong. I would instead recommend interested players to invest in a six-volume physical copy, …
Sunday Problem #7
Black to play.

Hekomi
Hekomi is a Japanese go term that is fairly often used in Japanese go jargon, but is virtually nonexistent in its English counterpart. ‘Hekomi’ is usually translated ‘dent’ or ‘depression’; but in go terms, I find the former translation not very descriptive while the latter will get confused with the mental state. ‘Hollow’ would make for a more fitting noun …
