hand 1: i would fold, given the info on the villain. its def. def. not a laydown that i would make in my home game though.

hand 2: call, getting 2:1 on money and the semi dry flop. If he has overpair, he has it. Would he call in BB with JJ or better? If he has you beat, its prob a set, but then he could be semi bluffing with a gutshot and 2 overs, or A8 or something.
