Villain is awful

I would not raise on 3rd. i think i would just call 3rd and not raise. i think it is worthwhile to see another card on 4th.

On river, i ould check. Your pair is exposed, he could see your possible hands as such, and this makes it better to check and call. it oesn't look lik the best spot for a value bet here.
