Villain's hand looks a lot like JJ+ in hand 1, fold turn and you're always smoked on the river.

Hand 2 you'd need a read that he isn't over-aggro to go broke here. Calling turn isn't as bad as hand 1, but I'd fold the river. Again, unless you have a read. I'm going to assume an unknown isn't ever pushing this river as a bluff with the bare A[img]/images/graemlins/spade.gif[/img] or something and he isn't value betting KJ or some [censored] unless he's nutso aggro.
