I studied this theorem:

Theorem

Let σ* be an ESS in a pairwise contest, then σ≠σ* and either

(1) π(σ*,σ*) > π(σ,σ*) , or

(2) π(σ*,σ*) = π(σ,σ*) and π(σ*,σ) > π(σ,σ).

Conversely, if either (1) or (2) holds for each σ≠σ* in a two-player game, then σ* is an ESS in the corresponding population game.

When might the first condition (1) be used? Mostly we use the second condition.
