When GTO mixes between two different decision, the EV of those different decisions are exactly the same.
For example:
If GTO player is betting 1x pot on the river with nuts or air, GTO defense is to mix 50% call and 50% fold.
But we can call 100% or fold 100% and it doesn't change our EV, because it is a frequency mistake (not a pure mistake).
If we call 50%, our EV is 0.
If we call 100%, our EV is 0.
If we call 0%, our EV is 0.
So you can deviate hugely from GTO frequencies without losing any EV vs a GTO player.
