Viktor Kortschnoi, undeniably one of the best experts and practitioners in the field of rook endgames, the most important type of endgame, shares his personal experiences from tournament practice in his new book. It begins with the basics of rook endgames, which can serve as a spark for the untrained, and then delves into position types that are theoretically difficult to grasp, providing precise and extensive analyses. He focuses not on general evaluations but on exact proofs. Those who consider rook endgames simple are mistaken, as stated in the preface. The true depth of these endgames is particularly illustrated by the famous endgame from the World Championship match Karpov – Kortschnoi in Baguio 1978, a treat for practitioners of all skill levels. As the Cuban World Champion José Raúl Capablanca once said: I owe my skill to the study of a thousand rook endgames! This book, a gem of chess literature, will facilitate future work.
