in snooker any touch is a 4 point foul, weather the ball moves or not, and it's not your shot anymore. since there is no ref or record of original placement we don't usually try to move it back.
in 9 ball I figured it would be a ball in hand if you bumped a ball, and the next players shot. I'm surprised that accidentally bumping a ball would have no repercussions, but I think that's what the WPA is saying here right?
I found a sort of similar puzzle in Snooker. If I was shooting black and bumped a ball with my shirt sleeve, even not moving it, then I think that's a 7 point foul. If I were shooting the yellow then it's a 4 point foul. We don't normally call balls unless they are close to one another and it is not obvious.
So what when you are approaching the table and bump a ball? It seems impossible to determine what choice a player would be making before he aims. the shooter could bump a ball before he is even decided, or he may even take aim and then change his mind on the color he is shooting, before he takes his shot.
I could be wrong and it may be that before the shot the ball bump is only 4 points, but if you misssed the black or hit a different ball or sunk the CB then it would be 7
maybe that's one reason serious rules may want every colored ball called out. I'm thinking that once a 5 ( blue), or more, is called then the bumping fault may increase accordingly to that choice, but I'm not sure.
a lot of what we do is just basically an homor system, it happens often a player will call his own fault and walk away, awarding points to the opponent, and often the shooter is the only one who actually noticed the fault.
What if i am aiming and the hair on my hand touches a ball, but not my skin, so I can feel it's there. I guess that's also a fault but there is perhaps a line where it becomes a bit rediculous. some may call that upon themselves while others may think its just going to a rediculous extent. then it becomes open to interpretation or confusion.
Maybe its a question that should be in the snooker section.
I accept that is' fine to modify house rules if all agree, to try to eliminate the fine details that spark controversy. Some rules only really work with a judge, like putting a ball back in place after a snooker and a miss. Putting balls back without any accurate record of where they started becomes confusing quickly. usually we just call it a friendly game and move past these things, Involve money , it can get different I guess .
I was visiting a local community center and lots are elderly, saw a guy bump a ball and just continue. I figured maybe their house rule is to not call such things. it might vary on venue. If it's a fairly new player then maybe it's ok just to note a fault and not mark it just so they know what the rule actually is. The more experienced may know what to do already.
In 9 ball I like the rule that you mucked up , you moved a ball, bumped something so you give the other player ball in hand and miss your turn if you have not shot yet, That may not be "correct"
