What infraction is defined by a person intentionally and knowingly violating or misrepresenting rules or procedures?

The definition provided in the question clearly aligns with the concept of cheating, particularly in the context of fraud. This infraction pertains to actions where a player consciously chooses to break or misrepresent established rules or procedures for a competitive advantage. Cheating is considered a serious violation in the Magic: The Gathering tournament community because it undermines the fairness and integrity of the game. It is not simply an error in gameplay but a deliberate act intended to deceive other players or officials.

Other options like Game Play Error relate more to unintentional mistakes made during play, Minor Misconduct usually pertains to behavior that is improper but not as severe as cheating, and Unsporting Conduct deals with actions that, while inappropriate, do not involve direct rule violations or deceitful intentions. Thus, the emphasis on intention and knowledge of wrongdoing distinctly marks cheating as the correct infraction in this case.
