I think that he will think his AQ is good more often if you bet flop..check behind on turn and then call river (or even raise river sometimes).
Thats still 2 streets worth of bets, but if he has something like
[Qs], you get a flop bet out of him. In your scenario, he probably check / folds the turn if hes that tight and he got to see the turn for free while drawing.
