Yeah, I guess the river bet is a given. I was probably over thinking the hand, though I'm unsure whether villain would pay off with an underpair. With that being said, I have shown weakness on the turn and will likely induce a river call. My main concern was a river check-raise, since I thought villain thought I'd bet any river when checked too, and therefore villain had a good opportunity to check-raise me. I also thought it was most likely he was holding two pair or greater and that furthered my concerns.
