MinES (Minimum Exploitative Strategy) vs MES (Maximum Exploitative Strategy)

It's a matter of changing frequencies and nodelocking opponent's response.

MES -> you have river spot where V should call with X part of their range but you are certain they fold everything but nuts. All of sudden, the EV of bluffing everything goes way up. However, if they are playing close to equilibrium and you choose this action, you will get wrecked.

MinES -> same spot but rather then leaving yourself open to counter-exploitation, you only increase the frequency of combos in your range as a bluff and maybe widen a few pips. You don't print as much as the MES but you go undetected. In solver, you could increase your mixes to full frequency and node opponent to fold.

There's not really any way to exploit your opponent that is unexploitable itself. To exploit you need to become exploitable.
MinES usually just refers to ways to exploit that are harder to pick up on but they give up some amount of EV, but I wouldn't say it's any specific thing.

MinES is more of a human construct that has to do with the ability of human opponents to reverse engineer your strategy based on the information you provide them, so i wouldn't try to calculate it

thanks，bro. I understand now.

There probably exist 0 loss adaptations whereby you switch between different nash equilibrium.
