Hello, I'd like to know if anyone could help me on this one, I'm working in preflop strategy against population and the solvers answers are outrageous. I find this concept of Minimally Exploitative Play on Acevedo book but I can't find anything on the internet that tells me if it's or isn't possible to calculate the minES preflop.

Could anyone point me a direction? I'm glad to share the informations I found if you help me on this one, thank you.
