AA with no spade

[Captain R]

Laggy player open-raises UTG. Mostly straightforward weak-tight solid MP cold-calls.
I 3-bet in SB with A[img]/images/graemlins/club.gif[/img]A[img]/images/graemlins/heart.gif[/img]. BB super-loose fish calls (he will never fold a blind, no matter what)
Everyone calls.

Flop is T[img]/images/graemlins/spade.gif[/img]9[img]/images/graemlins/spade.gif[/img]3[img]/images/graemlins/spade.gif[/img].

I check, BB checks, UTG bets, MP calls with his big spade or two overs or pocket pair, I check-raise...

What do you think?

I think the question here is whether to bet or check-raise. I think the flop is getting bet a huge amount of time, at least by a big spade. I'm trying to get fish out of the pot with his small pair, gutshot, small spade, whatever...

I also check to basically "get position" on the flop and see the action before raising/3-betting/folding.
