| A trigger strategy is
a class of strategies employed in a repeated
non-cooperative game. A player utilizing a trigger
strategy initially cooperates but punishes the opponent
if a certain level of defection (i.e., the trigger) is
observed. The level of punishment and the sensitivity of
the trigger vary with different trigger strategies.

Tit for Tat (the punishment continues as long as
the other player defects)
-
Tit for Two Tats (a more forgiving variant of
tit for tat)
-

indefinitely after the other player defects just
once)
