Indicating Line of Putt
Question: - I was playing a matchplay better ball and was putting on the putting. My partner decided to indicate the line of my put by placing his putter on the green. They moved away before I putted.
Is this a penalty?
Answer: - Yes
As your partner touched the putting green the penalty is loss of hole.
(If it was a stroke play competition it would be a 2 shot penalty) (Rule 8-2b)
You can however indicate the line of the putt providing that your putter does not touch the green
2nd Question: - If my ball was not lying on the putting green is there a penalty
Answer: - No
Providing the indication of the line is removed before the stroke is played. ( Rule 8-2a)
