[AbreuTime]

I would rather b/f turn than b/f river here. It's not like your hand can improve at all on river, and from your OP you dont make a mention of villain heavily donkbetting rivers after you show weakness. If you are planning on getting only 1 more street of value against a heavy river CR-er, might as well get value on turn. Would you check turn with nutflush against villain?

From your read on villain, I guess it depends on villain's ability to turn weaker-made hands (like 2 pair) into bluffs this deep.
