5-10 NL AA hand facing an overbet

[AdamBragar]

I'm still going through a down streak and I'm starting to more hands that used to be "standard" for me. Here's one from last night.

5-10 NL online.

I have 1k and am in the CO with black aces. MP2 limps in (has ~900). MP2 has a preflop raise percentage of around 1 percent but has a VPIP of around 50 percent. Mainly a calling station, but has shown some agression post flop. Haven't seen anything tricky from MP2 yet.

MP2 limps, I raise to 45, MP2 calls.

Two to the flop

Pot: 105ish.
Flop: J [img]/images/graemlins/diamond.gif[/img] 10 [img]/images/graemlins/diamond.gif[/img] 3 [img]/images/graemlins/spade.gif[/img]

MP2 bets out 150. I....?
