I agree if we think he'll bet the turn too with most of his holdings we can just check-call the flop and turn, but I'm not sure how many tag's are firing that turn shot with the weaker holdings.

Check-calling the flop and donking the turn has merit if he'll peel with AQ and AJ for sure. He might be more likely to call down some of his weaker pairs, too. If he'll fold AQ and call down the pairs to a flop check-raise anyway though then there's no reason not to check-raise the flop.

I think the fact that there's a flush draw out there will probably force him to call down more lightly. If the flop was a rainbow, a more passive line would probably be best since I think he can get away from his weaker hands easier with no obvious semi-bluff hands out there.
