Legal Shot
(1) On all shots, the player must:-
(a) Cause the Cue Ball's initial contact with a ball to be with a ball "On",
and then
(b) Pot a ball "On"
OR
Cause the Cue Ball or any Object Ball to contact a cushion.
(2) Failure to play a Legal Shot is a Standard Foul.
(3) Exceptions:
(a) On the Break, the conditions of a Legal Shot do not apply. See The Break
(b) When playing out of a Total Snooker a player is only obliged to meet the conditions of (1)(a) above. See Total Snookers.
(4) Interpretations:
(a) If the Cue Ball's initial contact is with an Object Ball that is touching a cushion, simply forcing that Object Ball into the same cushion does not constitute a Legal Shot.
(b) If the Cue Ball and an Object Ball are touching the same cushion, simply forcing the Cue Ball and / or that Object Ball into the same cushion does not constitute a Legal Shot.
