Yea, your reads on him due to these plays become extremely accurate, and its +EV. You take the pot 70% of the time if he has AK obviously, or an underpair to an overcard. I check that flop as well on that one however, and ive actually had AQ two pair on flop in a similar situation vs a player that bet 90% of flops, he checked behind , jack came, completed his hand, and of course I wasn't letting go ><
