A player must not give wrong information to his opponent. If a player gives wrong information, he loses the hole.
A player is deemed to have given wrong information if he:
fails to inform his opponent as soon as practicable that he has incurred a penalty, unless (a) he was obviously proceeding under a Rule involving a penalty and this was observed by his opponent, or (b) he corrects the mistake before his opponent makes his next stroke; or
gives incorrect information regarding the number of strokes taken to complete a hole and this affects the opponent's understanding of the result of the hole, unless he corrects the mistake before any player makes a stroke from the next teeing ground or, in the case of the last hole of the match, before all players leave the putting green.
A player has given wrong information even if it is due to the failure to include a penalty that he did not know he had incurred. It is the player's responsibility to know the Rules.
