In snooker , a shot where a player fouls by missing the ball on altogether. The miss rule allows for his opponent to have the player play exactly the same shot again, or at least as accurately as the referee is able to reproduce the ball positions. A miss usually occurs when a player makes an unsuccessful attempt at escaping from a snooker . It is a controversial rule aimed at formally discouraging deliberate fouls. In professional snooker , a referee will almost always call a miss on any foul where the player misses the ball on altogether, regardless of how close the player comes to hitting it, however no miss can be called when either of the players requires snookers to win the frame . If a player is called for a miss three times in a single visit while not snookered, he forfeits the frame ; to avoid this, players almost always play an easy hit on their third attempt, even if it is likely to leave a chance for the opponent.
