Matchplay, incorrect score on a hole
Responsibilities of Player and Opponent
(1) Telling Opponent about Number of Strokes Taken. At any time during play of a hole or after the hole is completed, the opponent may ask the player for the number of strokes (including strokes made and penalty strokes) the player has taken on the hole. This is to allow the opponent to decide how to play the next stroke and the rest of the hole, or to confirm the result of the hole just completed.
When asked for the number of strokes taken, or when giving that information without being asked:
The player must give the right number of strokes taken.
A player who fails to respond to the opponent's request is treated as giving the wrong number of strokes taken.
The player gets the general penalty (loss of hole) if he or she gives the opponent the wrong number of strokes taken, unless the player corrects that mistake in time.....
