Jonathan MacNeill An Instructor and member of the Professional Billiard Instructors Association, Jonathan's contribution to this book was the most physically demanding. Jon successfully completed all the drills and tested the accuracy of all the diagrams with cue in hand. He also edited and expanded the text so that it made sense to the novice as well as the expert, adding graphics as needed.
