By Nihon Ki-in (jap. Go-Verband), engl., 319 pages.
This book presents the reader a multiplicity of whole board problems ( 127 opening- and 129 middle game problems) with complete spectrum of possible decisions.
The reader should look open minded at the positions, as if it wear his own games, and so decide with the help of basic Go principles what the best move is respectively find the best strategic plan.
All problems aim at Dan players. The first 100 relativ easy Positions have 3 possible solutions specified, of which only one is correct.
After that the problems get more difficult, as almost no input or details are given, but rather lets the reader trusts his own intuition.
Anyone who knows the basic principals of Go, should be able to also solves these problems.
Anyone who cannot (yet) solve the problems in this book, can still learn a lot from the preoccupation with them and learn from the solutions, because they explain the basics of opening and middle game on a high level.
