This week’s problem is from Maeda Nobuaki 9p’s three-part tsumego collection, titled simply 前田詰碁集 (Maeda Tsumego-Shū), or Maeda’s Tsumego Collection. The three volumes together contain 585 relatively basic life-and-death problems that make for good reading practice for players of all levels.
A shortened version of the second volume can be bought on SmartGo Books under the title ‘Life …
While on the topic of endgame problems, it would be remiss of me not to bring up Kanō Yoshinori 9p’s excellent ヨセ辞典 (Yose-Jiten), or Endgame Dictionary.
When I was insei, this book single-handedly had the biggest influence on my endgame improvement. The book explains how to count values of moves (by swing counting), showcases many kinds of endgame …
Since we got started on the topic of whole-board endgame problems with Sunday Problem #20, here is another one.
This problem is from another Japanese problem book with an untranslatable name: 勝つヨセの絶妙な手順 (Katsu-yose no zetsumyō na tejun) by Mitsunaga Junzō 6p. A rough English translation would be Exquisite game-winning move orders in the endgame – feel free …
This is a whole-board endgame problem from Ōhashi Hirofumi 6p’s book, 爽快！勝ち筋探し (Sōkai! Kachisuji-sagashi) or Refreshing! Searching for the winning play.
If the title sounds strange in English, it is because sōkai does not translate very well; ‘refreshing’ or ‘invigorating’ are technically correct translations, but Western go players would rarely use them for the feeling of relief …
The carpenter’s square or ichigō-masu (一合升, meaning a small wooden container with a volume of 0.1804 litres) is one of the more dreaded tsumego shapes, especially by kyū players, which makes it an excellent topic for a Sunday Problem.
Should Black go for the carpenter’s square, or is there a better option available?
Black to play.
This shape appeared in one of Oscar’s games.
Black’s task, of course, is to live, but there are several ways to do so. The real problem is in finding the best way to live.

This problem is also from Xuanxuan Qijing, or ‘The Gateway to All Marvels’. This problem is titled 野狐箭, or the ‘Fox-Catching Arrow’, apparently because the shape ‘looks like the arrow’s head’ – personally, however, I fail to see the resemblance.
While its name may be dubious, the problem itself is one of the most ingenious I have seen.
This problem is from Xuanxuan Qijing, a Chinese tsumego collection classic from the 14th century; its English translation is named ‘Gateway to All Marvels’. This collection, along with Gokyō Shumyō, forms a set of tsumego books that all aspiring professional players learn by heart.
All problems in Xuanxuan Qijing have a title; this problem is called 老僧入定 or ‘An Old …
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 …
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.
