Rule 9. Information as to Strokes Taken

9-1. General

The number of strokes a player has taken shall include any penalty strokes incurred.

9-2. Match Play

A player who has incurred a penalty shall inform his opponent as soon as practicable, unless he is obviously proceeding under a Rule involving a penalty and this has been observed by his opponent. If he fails so to inform his opponent, he shall be deemed to have given wrong information, even if he was not aware that he had incurred a penalty.

An opponent is entitled to ascertain from the player, during the play of a hole, the number of strokes he has taken and, after play of a hole, the number of strokes taken on the hole just completed.

If during the play of a hole the player gives or is deemed to give wrong information as to the number of strokes taken, he shall incur no penalty if he corrects the mistake before his opponent has played his next stroke. If the player fails so to correct the wrong information, he shall lose the hole.

If after play of a hole the player gives or is deemed to give wrong information as to the number of strokes taken on the hole just completed and this affects the opponent’s understanding of the result of the hole, he shall incur no penalty if he corrects his mistake before any player plays from the next teeing ground or, in the case of the last hole of the match, before all players leave the putting green. If the player fails so to correct the wrong information, he shall lose the hole.
