I personally would check behind because getting to showdown helps me put hands behind me, move on, and play better for the rest of the session. If you are betting, you have to bet/fold, and that seems hard against this villan that maybe capable of a river "bluff" with a hand like JT or QT. I like to try to avoid awkward spots vs. good players, so i'd check.

Against a passive player its a definite bet/fold IMO.
