I am just curious to see what others would do in this situation. You are playing your bitter rivals in the league. This is the team that always wins the league and keeps your team in second place. You try a shot and no ball hits a rail. Your opponent was watching the shot and says nothing about a foul. Do you call the foul on yourself (knowing that he will run out with ball-in-hand) or do you say nothing and let him take the hard shot that is left on the table? Who's responsibility is it to call the foul?
