In Call Shot, obvious balls and pockets do not have to be indicated. It is the opponent's right to ask which ball and pocket if he is unsure of the shot. Bank shots and combination shots are not considered obvious, and care should be taken in calling both the object ball and the intended pocket. When calling the shot, it is NEVER necessary to indicate details such as the number of cushions, banks, kisses, caroms, etc. Any balls pocketed on a foul remain pocketed, regardless of whether they belong to the shooter or the opponent. The opening break is not a called shot. Any player performing a break shot in 8-Ball may continue to shoot his next shot so long as he has legally pocketed any object ball on the break.
