$55 NL SNG...Aces vs. Monotone flop

[tipperdog]

Anyone have a better line for this? 1st level (10/15) of $55 SnG, maybe 5th hand so no meaningful reads. EP this hand has approximately T950. I have about the same.

I am in cutoff with A [img]/images/graemlins/spade.gif[/img]A [img]/images/graemlins/club.gif[/img]. EP and MP limp. I raise to T70. Blinds fold and limpers call.

Flop comes 4 [img]/images/graemlins/club.gif[/img]7 [img]/images/graemlins/club.gif[/img]9 [img]/images/graemlins/club.gif[/img]. Checked to me and I bet T150 in to T235 pot. EP check-raises to T400. If you call (I did), EP pushes remaining chips (~T475) on blank turn.

What's the play?
