I was pretty lost at a few points during this hand.
My image is pretty tight at this table, the regs may have notes that i've made some silly calls in the past....

first caller is meh winning reg 16-11-2 with high (ca. 80%) fold to c-bet and little imagination, second caller (=flop micro-bettor) is unknown super loose passive station 40-0 and 20% fold to cbet type of player, button is 54-12 aggro who will bet draws (small sample, only real read), sb is 20-5 passive folding fish.

This flop strikes me as way ahead/way behind and i don't think a cbet accomplishes much, maybe I'm wrong though? Flop looks like a call > check-raise, considering turn bet-fold but checked instead, river seems easy value bet-fold, but how big? or is it check-call to induce, thing is, i don't think most of these players are gonna be betting worse very often
