Nordic Go Dojo

As of today, my English edition of Gokyō Shūmyō is available from Hebsacker Verlag in physical form, and from Gumroad as a pdf ebook.

From the back cover:

Gokyō Shūmyō is one of the most famous collections of go problems, containing 520 classic tesuji problems compiled and published by Hayashi Genbi in 1812. Its contents are divided into the categories of making life, capturing, ko, capturing races, connecting, oi-otoshi, cutting, and ladders.

This English edition of Gokyō Shūmyō is the first of its kind. Until now, Western go players have had to rely on Asian editions of the book to peruse its contents. Besides adding English annotations for problem solutions, this edition fixes dozens of mistakes in the source material and grades problems by their difficulty.

The problems in this book come from a wide range of difficulties, from 9-kyu all the way to professional level. The core audience of the book is dan players and players soon aiming to enter the dan ranks, but readers of almost all levels will find suitably challenging content in it.
