7-2. During Round
A player must not make a practice stroke during play of a hole.
Between the play of two holes, a player must not make a practice stroke, except that he may practice putting or chipping on or near:


(a) the putting green of the hole last played,

(b) any practice putting green, or


(c) the teeing ground of the next hole to be played in the round,
provided a practice stroke is not made from a hazard and does not unduly delay play (Rule 6-7).


Strokes made in continuing the play of a hole, the result of which has been decided, are not practice strokes.
Note 1:
A practice swing is not a practice stroke and may be taken at any place, provided the player does not breach the Rules.


Note 2:
The Committee may, in the conditions of a competition (Rule 33-1), prohibit:


(a) practice on or near the putting green of the hole last played, and


(b) rolling a ball on the putting green of the hole last played.
