Trembling-hand perfection Find

(a) all Nash equilibria in pure strategies in Table 10.12 and

(b) identify which of them are trembling-hand perfect.

Substituting the concept of trembling-hand-perfect equilibrium for the concept of Nash equilibrium would eliminate some problematic implications of the Nashequilibrium concept. The concept of tremblinghand equilibrium is, however, insufficient to deal with all problematic cases.
