4/8 Reverse Clarkmeistering

[Malachii]

4/8 Commerce Casino. Very LAGish game.

I have A[img]/images/graemlins/diamond.gif[/img]Q[img]/images/graemlins/diamond.gif[/img] on the button.

MP player limps, Cutoff (very aggressive preflop) limps, I raise, BB calls, MP 3 bets, Cutoff calls 2 cold, I cap, everybody calls.

(16 SB)Flop comes A [img]/images/graemlins/spade.gif[/img]7 [img]/images/graemlins/club.gif[/img]2 [img]/images/graemlins/club.gif[/img]

BB checks, MP bets, Cutoff calls, I raise, BB calls two cold, MP calls, Cutoff calls

(12BB) Turn is the 5[img]/images/graemlins/club.gif[/img]
Everyone checks to me, I bet, BB calls, everyone else folds

(14 BB) River is the 9 [img]/images/graemlins/club.gif[/img]
BB checks. I've seen him try to checkraise a flush before. What's my move here? Check and hope that I somehow have the best hand or bet out and try to get him to fold a poor club?
