Each problem is rated with a notation such as 5 ~ 7 kyu (級). In addition to the typical answers of alive (活) and dead (死), acceptable answers include: ko (劫), te ari (手有) and success, prevail (勝).

Bob McGuigan: Maeda was considered a master tsumego composer and these three volumes are true classics. Along with Gokyo Shumyo they have long been a standard recommendation of pros to amateurs wishing to get stronger. They were out of print for many years until the three volume set was reprinted. Each page has three problem positions on one full board diagram, some black to play and some white to play. The problems may be to live, kill or, occasionally, escape to the outside. Ko is sometimes a solution. Each book is aimed at a particular range of playing strengths: volume 1(beginner level), 10k to 4k; volume 2(intermediate level), 4k to 1k; volume 3(advanced level),1k to dan level. These ranks are, of course, approximate estimates only, and they are the old Japanese ranks which were much stronger than modern ranks, probably stronger than current American ranks. The problems tend to be difficult for the levels given if interpreted by modern standards. Each problem has a hint, in Japanese, such as "Use White's single stone to spoil Black's eye shape", or "Use two White stones as a sacrifice". These problem collections are distinguished by their coverage of basic life-and-death tesuji through imaginatively composed problems. Many of the shapes could occur in actual play. Ever since they were first published they have been considered musts for serious go students. Many subsequent authors have borrowed problems from these sets.
