when is a free ball awarded in snooker
Rules of snooker A free ball is a player-nominated substitute for the ball on when the player is snookered by a foul.[1] This is because the snooker in this case is produced by a foul and thus not considered legitimate. As such the player is allowed to pick any ball as a free ball, which is then effectively treated as the ball on, thereby voiding the illegitimate snooker. Once the free ball shot is taken legally, the game continues normally (although, if the offending player was asked to play the shot again, then the free ball is void, having to resolve the self-inflicted snooker).
