This lecture looks at a rare time that weak dominance can actually be useful!
Takeaway Points
- If your opponent mixes among all her strategies, then playing a weakly dominated strategy produces a strictly worse payoff than playing the strategy that weakly dominates it.
- Thus, you could not play the weakly dominated strategy in equilibrium involving such a mixture from your opponent.
