Betting at pool is a lot like pickpocketing. The winner can usually be determined before play begins.
Betting and nagging other players into gambling is what takes money out of the pool room owner's pocket. It drives paying customers away.
If you have a big ego, like you do, you must stroke the shaft of the cue into the air before you shoot to get everybody's attention that a fantastic shot that only you and Earl Strickland can fire, is coming right up. If the entire audience is not paying attention, get off the shot and start your pre-shot routine all over again.
Gamblers do for pool, what Mike Lebron and Buddy Hall did for ESPN coverage of big tournaments.
If you really think that is why some players stroke their cue in the air, you really have no clue. In fact, your other statements clearly show that you have no clue whatsoever.You just make up whatever excuses that sound good to you because you don't have enough faith in your own game to make any $$ off it. Wonder if you play poker for free also??
