I've rekindled my interest in chess and, not wanting to expend too much time on the game, have limited my reading to three books: on tactics, on the endgame, and on positional chess.
This book, serving the latter purpose, has 495 diagrams, mostly from practical games between top players, many of which are known classics. Each illustrates a point, and the author avoids copious variations. The moves usually extend from the diagram position to the end of the game. They are very well selected. As a result, my intuition has clearly improved in an important area of the game.
Gelfer's rigor is reflected in his impeccable English (no translator or editor is mentioned). I can't think of a single typo, in word or variation, and the text is clear, no nonsense and to the point. He seems to have honed the work, culled from his training manuals for the Israeli youth and women's teams, over years. This makes the book a pleasure to read.
My copy, which isn't a Dover edition (which have excellent bindings), is getting old (1993) and pages are beginning to fall out. But that's a good sign: it's due to the use the book has seen. Highly recommended.
