Nope! I could never fold that. You are only loosing to a 3, 44, and 77. It is really hard to put somebody on a bare 3, folding this here would just be super nitty imo.
The only hand i would be worried abut is A3, and we have that blocked. I guess he just played that 34 randomly out of the blinds. Some people are WAY to sticky from those spots.
