My feelings exactly. I will speak up I see an obvious mistake like shooting the wrong ball, or if I foul and the opponent doesn't notice (different scenario, i know). I look at it as what is more important to me ? Winning a game now and then because i didn't speak up? or being helpful and honest. I will err on the side of honesty every time.
I also appreciate the people who speak up. Especially in a tournament situation where not every table has a ref, if you are playing someone trustworthy, There is less likely to be a dispute.
I like being know for my honesty, and it gets me games everywhere i go in town. if someone is know to abuse the system or not speak up, it gets around quick. my good reputation got around quick. a bad one gets around quicker. We are a bunch of gossiping old men. Just look at the number of threads like this one.
How about ONE good set of RULES?
...that apply to friend or foe, good guy or bad guy.
I’ve got some experience running tournaments just like the OP....
..a lot of them were snooker in the 80s....caught two guys playing a full game when they
had tied...went over and scattered the balls.....on a tie game, the black is respotted, cue
ball is placed in the ‘D’ and flip to see who shoots....they said they agreed to play again...
...I told them “Everybody plays with one set of rules.”
If variations are allowed, a big tough guy can get his own way....
,,,,not in my tournaments.
