Is it correct that the rules for the opening break (pocket a ball or send the cue and two object balls to a rail) *only* apply for the opening break, and not for subsequent "breaks" of the 14-ball re-racked balls? In other words, for *all* shots other than the opening break the standard rules apply, i.e., pocket a ball or hit an object ball and drive either the cue ball or the object ball to a rail?
