  This article is not describing tit-for-tat. Declaring that tit-for-tat is the best cooperative strategy, and then declaring that any observed cooperative strategy must be tit-for-tat, is a bit of circular logic.

    No idea what you are talking about and it is tit for tat.

      I believe tit-for-tat refers to a very particular strategy, where I help you if you helped me yesterday, without considering whether or not you helped me last week or last month. Thus tit-for-tat is very inclined to forgiveness, and also to discard old friends.

        It punishes old friends who just punished you. Tit for tat is the best strategy in prisoners dilemma.
