the river is pretty gross..

one main thing i'd consider here is how passive the fish is, since a passive fish is probably never leading any Jx hands here. it kinda looks like he can easily have 2pr+ and isn't super happy about the 4-str8 board here.

on the other hand since it's about half pot you only have to be good one in four or so, folding or calling are probably both options. fish CAN show up with weird hands sometimes and you're probably NOT beat 100% of the time here.

cuz of all the combo draws etc, i think if you raise the turn it should be bigger, the price you're giving him is excellent.
