Which tournament official is allowed to deviate from the official guidelines?

The Head Judge is the only tournament official authorized to deviate from the official guidelines. This is due to the Head Judge's role, which involves comprehensive oversight of the event, including making final rulings and decisions that may be necessary for the fair and smooth operation of the tournament. The Head Judge has the experience and authority to interpret the rules and guidelines as needed, especially in unique or unforeseen circumstances that might arise during an event.

Other tournament officials, such as judges on duty or even the event organizer, do not hold the same level of authority regarding rule deviations. They are expected to follow the established guidelines rigorously to maintain consistency and fairness in adjudicating matches. Additionally, players, regardless of any authorization from the Head Judge, do not have the authority to alter or deviate from the guidelines.
