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 (F) The Break).
      b) When playing out of a Total Snooker a player is only obliged to meet the conditions of (1)(a) above.
      i. Definition: A player is in Total Snooker when it is impossible to play any part of any of the player's own Colour by way of a "straight line" shot. Leaving an opponent in a Total Snooker is not a foul.
      ii. If a player believes that a Total Snooker exists, the player may ask the referee for a ruling. 
      iii. If the referee rules that a Total Snooker exists, the player's obligations under the "Legal Shot" rule are relaxed as follows: - The player need only cause the Cue Ball's initial contact to be with a ball "On". Te requirement to pot a ball and/or cause a ball to strike a cushion is waived.
  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 the 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.
