Query: The most common of endings clearly explained!!

This book helped me to understand rook & pawn endgames like no other before it. I had previously read Pandolfini's Endgame Course, Capablanca's Chess Fundamentals, Tarrasch's Game of Chess, and Reassess Your Chess (which has a few pages on the subject). These are all good books. But I never fully comprehended rook endings until I read this book. I finally understand the Lucena & Philidor positions and Why They Are So Important. And much more... This book is cheap, short (only 70 pages), and chock full of extremely useful information. I am a strong B player and just beat my first expert due to this book!
