Yutopian book. Consists of 100 problems from Kido magazine's "Challenge corner". It is presented as a test of playing strength, where problems can have a difficulty level ranging from amateur shodan to pro.

Each problem features a "success rate" by the respondents to the magazine's challenge at the time of publication. The hints in the book were not offered in the original challenge.


David Carlton's [ext] review (with Tom Roseís comments)

Summary (by PJT): Impossible for an AGA 2 kyu and a BGA 4 kyu, also for various players up to 3 dan, but probably good if you are good enough!
Dieter: reviewing this book with KataGo in 2024. At first sight, the opening problem solutions are not endorsed.
Ulrich: this is a reprint of a special edition of Nihon-Kiin from 1981, where monthly problems of the magazin "Kido" are collected. The below mentioned examples have a "win rate = right answer" of 12%, 18% and 13%.
