The tit-for-tat strategy was found to be the most successful strategy in securing points in the prisoner's dilemma tournament over many rounds. This strategy involves starting with cooperation and then copying the previous move of your opponent, whether it was cooperation or defection. It forgives after one instance of defection and retaliates if the opponent defects again. This strategy is successful because it is forgiving, non-envious, and non-exploitable.
