Any person physically present at a tournament and not in any other category above is a spectator. Spectators are responsible for remaining silent and passive during matches and other official tournament sections in which players are also required to be silent.
If spectators believe they have observed a rules or policy violation, they are encouraged to alert a judge as soon as possible. At Regular or Competitive Rules Enforcement Level, spectators are permitted to ask the players to pause the match while they alert a judge. At Professional Rules Enforcement Level, spectators who are not members of the official coverage team must not interfere with the match directly.
Judges are people, and sometimes errors or even suspicious events are missed. Spectators may pause the match at Regular and Competitive Rules Enforcement Level. Spectators may often mistakenly identify an action or board state as illegal (often with missed triggers), so it’s important that a judge gets involved as soon as possible and that spectators give no information to the players during their match. For more information on different Rules Enforcement Levels, see MTR 1.12.
Members of the coverage team are allowed to bring attention to the judge staff about possible problems with the game.
Players may request that a spectator not observe their matches. Such requests must be made through a judge. Tournament officials may also instruct a spectator not observe a match or matches.
