AA... bad laydown?

[okayplayer]

I just had AA ($0.50/$1 NL) with 2 limpers, and I raise to $4, and first limper calls.
Flop: Q /images/graemlins/club.gif 2 /images/graemlins/spade.gif3 /images/graemlins/spade.gif
He checks, I bet pot ($9.50) and he calls.
Turn: 7 /images/graemlins/spade.gif
He checks, and I feel a trap, so I check.
River is a blank and he immediately bet pot ($27.25)
I think and feel that he has the (nut) flush, so I fold.

Is this pretty weak? I was going to bet the turn, and see what he did, but with the nut flush, he would smooth call, and that wouldn't let me know if I was behind. So anyone else make this laydown? /images/graemlins/confused.gif

I don't quite understand how you can feel trapped? I think there is a fairly wide range of hands that he check calls the flop with.

I take it you don't have the A of spades.
How deep are the stacks?

His check on the turn followed by a bet on the river might just be a flush. But, it may also be top pair, since he now probably doesn't think you have a flush. I'd probably call the river here and expect to see AQ, KQ, QJ enough times to make it a possitive EV call.

Only my opinion,
