Junior, if you were to examine the BCA rule book, I think you can get an idea of how detailed the rules can be for this game and even the BCA rule book occasionally fails to address some circumstances that arise in common play.
My point is, the APA relies on common sense and the general rules of pocket billiards. Unfortunately, for some people, this isn't enough and they insist that everything needs to be worded out appropriately.
All I can say is, after over two dozen matches in team post-season play, with experience in Las Vegas, NV under the highest scrutiny, I can assure you that the spirit of the rules must remain intact. You are allowed only the alloted amount of coaches per game. If, in any way or form, a person tries to expand on that number, they take the risk of penalties beyond the scope of that mere game and in some instances, could risk their membership in the APA.
An example would be a player who has already taken their time out and is about to shoot the eight-ball in a pocket their teammates strongly disagree with. If the coach asks the player if he'd like to take a time-out, this could be contrued as a coach and frankly, he better have one available. Of course, there are legitimate mistakes but as we all know, some circumstances are more obvious then others.
When looking over any given rule, ask yourself this: What is the APA trying to accomplish? What are they trying to create/prevent? Does the issue I raise contradict their goal or is it an entirely seperate issue?
The problem I have with your situation is that it contradicts the intention of the rule in question. In Las Vegas, the only time a player can even speak to their coach is when a time-out has been called. There is no dialog about whether a coach should be taken or not. There is no sideline conversation while the other person is shooting. The match strictly takes place between two players with intervention only occuring for the duration of one minute per game (two for players ranked lower then 4) and only during that announced time-out may any sort of advice be relayed to the player.
Constant dialog about whether a time-out should be given or not can be seen as advice. If a player has the choice of shooting a ball in one pocket or another, the coach can ask if they'd like to take a time out, hence making the shooter reconsider what they're about to do.
Be careful with your strict interpretation of the rules. I can assure you that there are many LO's and referees that will not see it your way. Trust me, we've all tried that one already!
Jude!
