my question: why are you not betting the turn here? i assume you have him on a range of sorts, so what is it?

all of the hands on 2p2 he played passively except for the TPTK. the flush that he just called with had a paired board, as well as not being the nut flush. he clearly has a flush here though. it seems that the only time he can bet the river is when the scare card that falls does not scare him, but rather makes his hand. this leads to the question of why you are raising here if his range is a flush, but you cant call if he reraises?
