Any foul shot in which a player's cue tip stays in contact with the cue ball for more than the momentary time commensurate with a stroked shot . In the game of snooker , it is considered a push if the cue strikes the cue ball more than once in a given shot (a double hit ) or if the cue stick , cue ball and ball-on are all in contact together during a shot (if the cue ball and object ball are frozen together, special dispensation is given provided the cue ball is struck at a downward or otherwise "off" angle; that is, not directly into the line of the two balls).
