"14. Foul and a Miss
(a) The striker shall, to the best of their ability, endeavour to hit the ball on or a ball that could be on after a Red has been potted. If the
referee considers the Rule infringed, they shall call FOUL AND A
MISS unless:
(i) any player needed penalty points before, or as a result of, the
stroke being played and the referee is satisfied that the miss
was not intentional;
(ii) a situation exists where it is impossible to hit the ball on.
In the latter case it must be assumed the striker is attempting
to hit the ball on provided that they play, directly or indirectly,
at the ball on with sufficient strength, in the referee’s opinion,
to have reached the ball on but for the obstructing ball or balls."
By calling a "miss', the ref is not suggesting it was deliberate, only that a better attempt can be made.
