Exactly, only a banger hates to be told to stop, take a deep breath and tell him a very good option to try and win the game. I won't even coach anyone lower than a 5 unless they ask. And when they mess up I tell them you should have done this. Then they say why didn't I tell them. Well, cause you got mad last time I told you, as if my suddent interruption for you take a deep breath, and think about a better option is what caused you to miss and not that horrible stroke you have
I'm not a banger and I hate being interrupted at the table. When I was playing APA 8-ball, five or six years ago, the other 7 on the team would do the same thing. He only did it twice before I told him I would lose my s++t if he did it again. He would do it to the other players as well and I could always tell it threw them off. I Just started playing APA 9-ball again last session after five years off. I personally never stop a shooter from shooting to give a time out. I have already instructed my players that if they feel they need a timeout then they should ask for it. I will tell them what I feel they should have done, if they say "why didn't you tell me?" my response is "why didn't you ask?"
A lot of it matters on the shooter. If a shooter doesn't mind or actually prefers to be stopped in this manner then that is fine for that shooter. If a shooter, regardless of skill level, does not want to be interrupted at the table then their wishes should be respected. The only time I will ever stop a shooter who doesn't like to be interrupted is if they are hooked and I can tell they are pretty much dead in the water the way they are attempting to kick. Other than that I will wait.
Pool is typically an individual sport, there exists a whole different set of dynamics when a team environment is brought into it. I enjoy the feeling of being on an island, just me and the puzzle of the table. It is no one else's puzzle to solve but mine.
I feel that there is a lot to be learned from doing the wrong thing and getting burned for it. It leaves an indelible impression that is hard to forget in the future. Although you can also make the argument that guiding a less experienced shooter on the proper thing to do in a tough circumstance is helpful in teaching them what they should be doing, I don't feel that the impact is as great as learning from your mistakes. The time for teaching is not in the middle of a match. Instruction after the shot, while their opponent shoots, affords you far more opportunity to expound on the ideas that you are trying to relay to them. If you want to fix deficiencies in your teammates games you have plenty of opportunity to do so on the practice table.
I will give advice to anyone who asks for it, regardless of skill level. I learned a long time ago not to offer up advice that is unsolicited, unless I feel the benefit outweighs the typically negative response you will receive.
