10NL, 2 pair flop, facing river aggression

fwiw if he has an 86% fold to cbet (over a reliable sample) then hes not continuing with "any pair or naked gutshots" ....he's more likely continuing with Ax/ and some flush draws /and some made straights/ AJ and QJ/KQ...i would bet more on the turn....and idk if at game speed i would be able to find a fold on the river but the rivers looking mighty foldy to me, i doubt he is turning AT or AK into a bluff here
