My plan was here to call his bet and see if he follows up on the river. If he follows up on the river I must assume that I'm beat and I can safely fold. However I don't think I can fold to his donk as I feel villain can do this with a wide range of hands. Maybe TPWK trying to find out if his K is any good, or a monster like a set.

What would you do and what do you think about villain's range on the turn?
