We raise pre for 2.5BB and get 3 bet to 10BB. In order to break even on a call we need to claim 7.5BB of the pot postflop. In order to construct a calling range here I have been running sims on a gto solver(gto+) on lots of different flops and calculating the average ev. I assign villain a range and then I give myself a reasonable range for calling. If my average ev is below 7.5 I tighten up a bit until I reach a range that claims 7.5BB on average. I do understand that the ev given by the solver is of two players playing perfectly against each other. However while I will make mistakes postflop, so will villain, therefore this method should be good if my skill is equal or superior to that of villain's. So what do you guys think?
