Tom In Cincy said:In an "un refereed' match, it is 'cue ball fouls only'
Since the incoming player only moved the object ball, play would stop and opponent would place the object ball back into the original position or leave it where it is.
If the incoming player 'B' moves the ball and doesn't stop play (takes it upon himself to replace the object ball) this could be considered a foul, and in some cases, 'unsportsman like conduct' with forfieture of match or at the minimum a 'warning'.
Player B's turn at the table (under normal circumstances) does not start until the cue ball passes the head string. If player B commits a foul (moving balls and not letting them be restored by his opponent) he could be given a foul (minus 15 points) for unsportsman like conduct or forfieture of match.
If the 'unsportsman like conduct' is enforced, Player A could get a 15 ball rack and have player B break under opening game conditions. Two Object balls to the rail plus the cue ball or it is considered a foul.
I thank you very much for the time and effort you obviously put into your answer, which seems to answer this question for pretty much the whole world. However, as I mentioned later in the topic, and I will edit the first post, in europe all games are all-ball foul, which is pretty much the only difference in the rules that I can think of, but in this case obviously it makes a big difference. So keeping that in mind, what would your answer be?
