50 NL TT hand

[lmw]

villian is loose passive preflop and agressive post flop. first hand villian had raised this session. His agressiveness post flop tells me he would make a c-bet with an unimproved AK-AQ, but his passiveness preflop and his flop reraise tells me i'm probably up against a bigger pair here. Do I call the all in getting ~3-1 on the call or lay this down?
