Rule – 4.1b(1)
You must not start a round with more than 14 clubs or have more than 14 clubs during the round.
If you start a round with fewer than 14 clubs, you may add clubs during the round up to the 14 club limit.
When you become aware that you are in breach of this rule by having more than 14 clubs, you must immediately take the excess club or clubs out of play to do this. You must take an action that clearly indicates each club that you are taking out of play before making your next stroke, such as by advising another player or turning the club upside down in your bag.
