In the vast ocean of chess literature there are relatively few books about the endgame, and only a few of them can be considered true chess classics. And the most outstanding among the classics — Reuben Fine's book "Basic Chess Endings".
Reuben Fine (1914−1993) was for a long time one of the best chess players in the world. As an author, Fine showed himself to be an excellent analyst who understood the full depth and peculiarities of the endgame. Having studied various types of standard positions, Fine established useful rules for practical play and proved himself to be an experienced teacher who, using skillfully chosen examples, was able to teach the reader all the necessary lessons and introduce him to the basic ideas of the endgame.
Many generations of chess players in different countries of the world keep copies of “Basic Chess Endings”. For example, Mikhail Botvinnik considered Fine's work the most worthy of all that had ever been written on endgame theory.
