I'm also bothered by how few people have read the rules, and that sadly includes some world champions. I think it is just how people learn things -- they trust word of mouth more than things that are written, and consequently their pool shark Uncle Joe is their rules authority.
Tap tap tap...
I have been training referees for many years, and in every class since I started I have included the statement that "a player's knowledge of the rules, and especially physics as applied to the rules, is usually inversely proportional to their skill level and/or experience (read:age)." I always deliver the line a little toungue-in-cheek, but the degree of truth definitely leans towards the high side. Another star of my class, relevant to the OP, is the player I call Mickey Masse, whom I channel for demonstrating various legal and illegal masse shots. You all have your own Mickeys out there somewhere. Poor Mickey thinks anything that happens when the stick goes vertical is going to be automatically legal.:sorry:
Here is one of the things on Dr. Dave's site:
http://billiards.colostate.edu/normal_videos/new/NVB-61.htm It's a video quiz on the rules -- a video "You Make the Call." It's 100 shots with score sheets and answer sheet.
This is an excellent test, and you should take it faithfully (at least) the first time, looking at each shot only once. The only downside I have been able to find with it are some potentially deceptive camera angles on just two or three of the shots. I talked to Dr. Dave about those, and it's part of the reason that there are a couple that, even in a tournament setting, could go either way.
One shot in particular we spent about five minutes looking at and breaking it down using the systems we train our refs with before I finally realized that the balls were conforming to the teaching system but it was the camera's perspective that was causing an illusion that they were not. Once the illusion was corrected for, everything fell into place. Dr. Dave agreed. (I kept after it doggedly because it was on of only two I missed on my first pass.)
Anyway, as I said, take the test and be honest about looking only once on the first pass. Be sure to print out the scoring forms before watching the video...
