sentences:  A free ball scenario does not occur when the ball gets stuck at the edge of a pocket jaw (commonly referred to as "angled") in such a manner that the player is unable to hit any ball on.This is because according to the official snooker rules a ball is snookered only if its way is obstructed by balls not on.In this scenario, after a foul, the player may choose to either take the shot from the current position or ask the offender to play again, as per the usual rules on fouls.
