Fukui Masaaki, engl., 126 pages.
Some people may think that the 5x5 board is just a reduced version of Go. Fukui Masaaki’s little creations show that much of what is complex and profound in Go can be found in the tight confines of the 5x5 board. The problems cover endgame moves,aspects of life and death, attacking and defending, judgments based on calculating territory,the presence or absence of ko threats, and even things pertaining to the realm of middle game fithing. Not only is this book useful for improving your understanding of shapes and techniques, it is also a lot of fun!
