The most difficult problem ever.
Igo Hatsuyoron 120
The most difficult of all Go problems, created by Inoue
Dosetsu Inseki (1646 - 1719), has still not been solved
by professional Go players. Has the long-standing
collaboration of three amateurs from Germany, and the
United Kingdom, now found the answer?"
This book presents the most profound analysis of the
famous problem of the Igo Hatsuyoron. It summarizes
the early research and reveals the latest findings,
apparently destroying the known solutions.
