Since the IP coldcaller's range will be tight (assuming he's not a fish w/ loose range), I don't think cbetting range for 1/3pot will yield the best result (since villain's range don't contain many weak hands that will fold to 1/3pot + he's IP, unlike in BvB where both ranges are wide so we can still range bet on many boards even OOP). So it's either we use a range check strat or a mixed strat on all boards. I know mixed strat is the higher EV, but since I'm only human who can't memorize all the correct freq, I'm thinking of simplifying my strat on flop by range checking on all boards. My question is, is the EV loss of not using a mixed strat negligible?
