Smooth calling villain

[Warpe]

Nothing exciting here, but against a smooth calling opp I always get suspicious of being slowplayed. Check this down on the river?

Raise more pre-flop, on the flop the min bet looks like a draw so I'd check the river. You may loose value from Qx but a ck-raise would be too painful.

I check that behind. You could bet/fold, but AQ might raise there and push you off your half of the pot.

I don't see many hands that you can value bet.
