The Rules of Golf are tricky! Thankfully, we’ve got the guru. Our Rules Guy knows the book front to back. Got a question? He’s got all the answers.

I switched to a new Odyssey Arm Lock putter about a month ago. Meanwhile, I developed golfer’s elbow, so I bought a brace with a pad that presses on my forearm. The putter shaft rests against this pad during the stroke. Putting feels more stable with the brace, and I’m holing more putts too, which made me wonder: Is the combination of brace and putter legal? —Chip Chase, via email

Question: How’s that arm feeling today, Chip?

Under Rule 4.3b, if you have a legitimate medical reason to use the support, and the committee in charge of the competition decides it doesn’t give you an unfair advantage over other players, then you’re free and clear to brace yourself.

It’s strongly suggested that you talk beforehand to the committee (which may or may not want, say, a doctor’s note to validate the injury) so questions aren’t raised during or after play. Without an exemption, you may fall afoul of Rule 4.3a, “Allowed and Prohibited Uses of Equipment.”

That’s a tiered penalty, with the first infraction the general penalty of two strokes in stroke play or loss of hole in match play, followed by disqualification for a second infraction.
