Small Encyclopedia (Nihon Kiin Handbook Series Vol 2)
by The Nihon Kiin
This book covers basic opening strategy. Although a few common corner openings (joseki) are discussed, it concentrates on applying the basic principles of wholeboard openings (fuseki), so you can choose the joseki most suitable for the wholeboard position. After reading you will find it easier to figure out what is important on the board and what to do when your opponent departs from the flow of the game.
