Robert Byrne is a columnist for Billiards Digest and in the United States he is considered one of, if not the best, billiards and pool teacher. This book is the one the US pros recommend first and the only one recommended if you can only afford one instructional book. Byrne takes you from cue selection to very hard shots and explains the use of English (spin). The diagrams are the best in print. I have two copies of this book--one to archive and one to spread out on my home pool table to study from and use the drills Byrne depicts. You simply cannot go wrong with this book. Plus the author has a sense of humor.
