S. Foul Jaw Snookers.
If an opponent fouls and the Cue Ball come to rest on or near a Jaw
(curved part of a cushion), and that jaw is preventing the player from playing
the finest cut possible on both sides of any of that player's own colour by
way of a straight line shot, the player is deemed to be Foul Snookered and
all the rules pertaining to a Foul Jaw Snooker will apply.
