1. Tit for Tat cooperates on its first move and from then on copies the other player's previous move. Once you discovered that, you probably realized that you gain nothing by defecting (until the last move). In this way, Tit for Tat trained you to cooperate for mutual benefit, unlike Massive Retaliatory Strike. How would a Tit for Tat strategy address imperfect communication, where cooperation might be mistaken for defection? (Imagine two players using the TFT strategy on each other with occasional "accidental" defections.)
2. Just as TFT never wins, there are strategies that never lose. For example, the strategy that defects on its first turn and thereafter copies the other player's previous move. What is the disadvantage of playing this strategy?
3. How does the nature of the game change if your goal is to beat your opponent by the largest margin?
4. How does the nature of the game change if your goal is to maximize the total gain for you and the other player?
5. Provide a real-life example of Tit for Tat strategy, where people are cooperating out of self-interest.
