By now, every golf person on earth knows what happened Friday at the Masters. Additionally, every golf person on earth has an opinion on the ruling that ultimately generated a 2-stroke penalty for Tiger Woods.
Way back when during my apprentice days here is what I was taught: No one can possibly know all the Rules of Golf. As a Golf Professional (as in not a professional golfer) what you are required to know is HOW TO USE THE RULE BOOK. There are PGA Professionals who have spent a lifetime in the Decisions Book. Google the Rules of Golf Decisions Book, find Rule 26 and then follow that up with Rule 33 – which was revised in 2011. These are the sources of the Tiger Decision. I like Bondy’s view as expressed in the link below.
