Rook endgames are the most important to study, because they are the type of endgame you will face most often over the board. Working on Rook endgames gives the biggest bang for your buck. World-class grandmaster Sam Shankland explains technical rook endgames in a way that is clearer, better organized, more concise, and easier to understand than any previous work. After learning the vital set positions, the reader is offered lots of rules and guidelines to correctly assess any theoretical rook endgame they have not yet memorized. The sister volume – Conceptual Rook Endgames by Jacob Aagaard – shows how the theoretical knowledge shown in the present book is used in advanced practical play. GM Sam Shankland is the 2018 US Champion, 2016 Olympiad gold medal winner for teams and 2014 individual gold medal winner. Further information about the book is available at qualitychess.co.uk.
