I would talk to the arbiter (tournament manager). It is his job to organize and make sure the rules are applied. 🐾
The arbiter's job is to see that the Laws of Chess are observed and make decisions in the best interest of the competition, but must not interfere with the game otherwise. If a rule is broken, the arbiter may choose from a number of penalties including the following:
warning the offending player
increasing the remaining time of the opponent
reducing the remaining time of the offending player
declaring a game to be lost
reducing the points scored in a game by the offending player
increasing the points scored in a game by the opponent
expulsion of the offending player from the event.
The arbiter may also expel offending spectators from the venue. Spectators are also forbidden to use mobile phones at any time in the playing area, and may be expelled for it. Member federations are allowed to ask FIDE authorities to give an official decision about problems relating to the Laws of Chess.
my opponent during a tournament was tapping a piece on the table. I told him to stop. Then, he told me to shut my pie hole. What can I do if my opponent is abusive?
