Get strong at Go series
A series of Go books by Richard Bozulich published by Kiseido.
The covers all have pictures of angry warriors. Some of them are throwing a goban, some of them are standing on it. The stones are all over the floor.
Get strong at Ko was originally planned as the 10th volume but never published. Ko is addressed in the book All About Ko of the Mastering the Basics Series.
The Get Strong at Go Parodies page gives an impression of just how popular this series is.
