Cheating will not be tolerated. The Head Judge reviews all cheating allegations, and if he or she believes that a player has cheated, he or she will issue the appropriate penalty based on the Infraction Procedure Guide or Judging at Regular Rules Enforcement Level document. All disqualifications are subject to DCI review and further penalties may be assessed.
In short, cheating occurs when a person breaks a rule, is aware that he is doing so, and is attempting to gain advantage from his action. For a more detailed discussion about cheating and how to handle this infraction, see IPG 4.8. The penalty for this infraction is Disqualification, and the Head Judge must follow the Disqualification Process.
