Two examples of strategic equilibrium are given. The first example is a two-person game with a unique dominant strategy for each player where the dominant strategy equilibrium is not extensive form perfect. It is argued that the concept of quasi-perfect equilibria may be superior to that of perfect equilibria. The second example is a two-person game with perfect information, a unique subgame perfect equilibrium, and a unique stable set, but where the latter allows different outcomes.
