DVORETSKY'S ENDGAME MANUAL by IM Mark Dvoretsky is one stop shopping when it comes to endgame study. The noted Russian trainer has produced a classic guide to learning the endgame that not only teaches you essential theoretical positions but also important concepts like "zuzwang", "shouldering" and "pants" – creating widely separated passed pawns in opposite-colored Bishop endings liked flaired trouser legs. 

This is a big book but Dvoretsky has helped the student concentrate on what is most important  by highlighting in blue what he considers essential material to master. There is plenty of prose to explain things and exercises to test the reader. Study this book carefully and you will soon be defending the weak side of f- and h-pawn Rook endings like Smyslov!

Highly recommended.
