To learn and to play endgames well the chess player must love endgames' - Lev Psakhis. Different kinds of endgames have specific characteristics and rules. Every serious player must know many typical positions and main principles of all types of endings. That knowledge should help us during the game, but it is not enough to become a good player, not yet. There just too many different endings, some of them with two or more pieces, some are very complex. To be comfortable and play well those complex endings require specific knowledge and specific ways of thinking. We will call it 'endgame thinking'. I chose to write a book on advanced rook endings as I simply did not wish to write another book that would be like the many already available. I have done my best to present analysis and articles I have written over the past 10-15 years. Th is work has been presented in my daily coaching sessions, seminars, workshops, etc. The material has helped a lot of trainees to develop into quite strong players gaining international titles and championships. Now, it is your turn to taste and enjoy it!
