I'm not thrilled with raising with Q9, but I like the play of the rest of the hand. On the flop you've got a pair hu, and AK/AQ are reasonable hands for the Villain. On the turn you've got an open-ended to go with the pair, so you have to call again.

I'm not sure what the Villain is thinking with the check-raise on the river. If you don't have the straight, you're liable to check after, and if you do, he's check-raising with the losing hand. Seems like a losing play to me.

I'd consider three-betting his check-raise, but I don't know if it's right. After all, AQ is one of the hands you've put him on from the beginning, and you'd hate to lose two the times he has it, especially if he might fold when he doesn't.
