1. Also splitshot and split hit. In pool, a type of shot in which two object balls are initially contacted by the cue ball simultaneously or so close to simultaneously as for the difference to be indistinguishable to the eye. In most sets of rules it is a foul if the split is one in which one of the object balls is a (or the only) legal target (ball-on) and the other is not; however, such a split is commonly considered a legalshot in informal bar pool in many areas if it is called as a split and does appear to strike the balls simultaneously).
2. In pool, the degree to which racked balls move apart upon impact by the cue ball as a result of a breakshot.
3. In snooker, a shot sending the cue ball into the pack of red balls and separating them (after potting the ball-on). At least one split is usually necessary in each frame, since the original triangle of reds does not allow any balls to be potted reliably.
