What must a referee do before a bout begins?

Before a bout begins, it is essential for a referee to brief the fencers on the rules and procedures. This step ensures that both competitors fully understand the regulations governing the bout, any specific rules that may apply, and the expected conduct during the competition. This briefing serves not only to set clear expectations but also to foster a spirit of fair play and sportsmanship.

While wearing the official uniform, conducting a warm-up, and checking the scoring equipment are all important aspects of a referee's responsibilities, they do not specifically address the need to prepare the fencers for the bout. The briefing directly impacts the fencers’ understanding and readiness, promoting a smoother and more organized competition. Therefore, this clarification of rules and procedures is a critical component of the referee's role before the bout commences.
