His turn raise was really scary, but we have to call 2 pair here.
I dont know about river, but don't see many value hands in villains range besides 33(1combo) 88 (1combo) A3s maybe (2combos) 45s(4combos)
on the other hand, there are also very few bluff hands, so folding here can be an option... hmmm
