• Start With C
• If the opponent previous move was to cooperate, my move is to cooperate
• If the opponent previous move was to defect:
  • If this is the first time the opponent has ever defected, my move is to cooperate
  • If not their first defection, evaluate all of the opponent's prior moves:
    • If he has defected more than 50% of the time, my move is to defect
    • If he has defected between 10% and 50% of the time, my move will be to defect randomly using a 50% probability
    • If he has defected less than 10% of the time, my move is to cooperate
