You might not think talk of morality is appropriate in pool--after all, pool has quite the sullied reputation--despite the efforts of many room proprietors and other influencers to make a family-friendly and socially welcoming atmosphere.
Yet the question arises for many players during competition. Do I go and do then wait to see what happens, or ask before I leap? Let's keep our answers simple and easy:
1. "If you have a doubt, leave it out." For example, if you are uncertain whether your clothing may touch a ball for a shot you need to stretch to reach for, don't let it touch (most tournament rules consider any ball touch from anything other than your cue stick's tip to be a blatant foul, even if the ball does not move as a result).
2. Be your own referee. Strictly abide to the rules of pool, and strictly call fouls on your opponent, if politely, yet loudly enough for them to hear your call. Many is the time you will lose the game otherwise, and feel resentment to the player who fouled.
3. Take moral stock. Do you really feel that slipping in a few illegal moves here and there benefits you? Even if you are hustling the pool game for cash, permission and forgiveness are equally moot when the loser catches you cheating and breaks a cue stick over your skull.
Overall, I recommend you err on the side of seeking permission first, not forgiveness. And if you fail to acquire permission, tough it out and play by the rulebook. You'll feel better about yourself and better about your billiards achievement.
