Tough spot with AA on the turn.

[Jezebel]

Live 20/40. I have played hundreds of hours with this particular lineup.

Villan open limps UTG and it is folded to me on the button. I raise with A [img]/images/graemlins/spade.gif[/img]A [img]/images/graemlins/club.gif[/img] and it is folded back to the villan who calls.

Flop comes 2 [img]/images/graemlins/heart.gif[/img]7 [img]/images/graemlins/diamond.gif[/img]Q [img]/images/graemlins/heart.gif[/img].

My opponent checks, I bet and he calls.

Turn brings a 4 [img]/images/graemlins/heart.gif[/img], and my opponent checks. As he checks I pick up a tell that he is planning on checkraising if I bet. The only hands that this particular opponent will checkraise the turn with here are a made flush, a set OR a flush draw regardless of how big. If I check it through there is a high likelyhood that he will bet the river.
What is my best line? Bet and call down, or check it through and hopefully induce a bluff on the river if a blank falls.

Thanks for your input.
