Villian has been playing better than average showing down good hands when he has had to, (pushed once in the SB into me, a couple of pushes from the button). Difficult to tell how loose/tight he is? I had raised in the previous round UTG with AQs and he thought about it before folding, so i showed (bad move?)

Is this an autocall to his push? there is 4305 in the pot and another 2205 for me to call so just under 2:1 which is good unless he has an overpair. So do I want to let him double up or am I +ev here?

Thanks
