What should a player do if they notice a potential rule violation by an opponent?

A player noticing a potential rule violation by an opponent should notify a judge calmly. This is the most appropriate course of action as judges are trained to handle these situations and will ensure that the game is played fairly according to the rules. By involving a judge, the player ensures that any issues are addressed in a structured and unbiased manner.

Keeping quiet and letting it go does not help uphold the integrity of the game and can lead to ongoing violations or unfair advantages. Confronting the opponent publicly could create a hostile environment and may escalate the situation unnecessarily, which can be disruptive to the event. Assuming that the opponent knows the rules can lead to further misunderstandings and a lack of accountability in gameplay, as it may enable continued infractions without correction. Thus, notifying a judge calmly preserves the integrity of the match and encourages a fair and pleasant competitive atmosphere.
