How do I handle hinders, distractions and coaching?

Question

Accepted Answer

Hinders: you must validate any hinder a player calls. If it's valid, replay the rally. If it's not, it's a fault against the player who called it (Rule 20.H). Distraction: if, in your judgment, a player distracts an opponent who is about to hit the ball (for example, loud noises, stomping, erratic paddle waving), it's a fault against that player (Rule 20.I). Coaching: except during time-outs and between games, players must not receive coaching from anyone other than their partner (Rule 20.G). For illegal coaching, you may assess a verbal warning or a technical warning against the side receiving it (Rule 20.G.1). Electronics: players can't wear headphones, earbuds or any other audio communication device during play, other than prescribed or necessary hearing aids (Rule 18.D).
