It's not cheating regardless of what you think. It's not written anywhere that I have to tell you anything about the match other then "Push" or "you're on two"
The other player should not be rewarded for their ignorance.
So you don't mind if I crouch down right behind you on every one of your shots to make sure you don't accidently tap the cue ball with your tip on a practice stroke? And if it's ok, I'm going to stand right up next to the table (instead of respectfully in my chair) and police every one of your shots for the slightest hint of a foul. Is that cool? But don't worry, I realize pool was originally termed "a Gentleman's game" by Royals and I have more class, honesty and respect for my opponent than you obviously so feel free to just sit back, relax and have no worries. I don't need to win that way and will ALWAYS and forever call fouls on myself. The Pool Gods love it!
