AA 3way reraised pot OOP

[HEK]

I know I screwed up preflop here. For some reason I thought it'd be brilliant to flat call BTN's raise hoping CO would pop it to isolate and then I'd just shove getting the deep stack in the middle preflop or even a 3way all in.

The hand...CO is D4Donkey and BTN is JPeggg or w/e. Both are pretty decent tags but JPeg is a bit more on the wild side and makes some rediculously crazy all in moves with v premium hands and (sometimes) marginal ones so I def expect him to shove with QQ/KK here. Diamonds for him in this situation are unlikely but it's possible.

First I need a plan:

Full Tilt Poker
$2/$4 No Limit Hold'em Ring Game

<font color="black">Stack Sizes</font>
BB: $1984.25
UTG: $717.80
CO: $1014.30
BTN: $397.50
Hero (SB): $913.4

<font color="black">Preflop:</font> A[img]/images/graemlins/heart.gif[/img] A[img]/images/graemlins/diamond.gif[/img] ($6, 5 players)
UTG folds, <font color="red">CO raises to $14</font>, <font color="red">BTN raises to $50.50</font>, Hero calls $48.50, BB folds, CO calls $36.50

<font color="black">Flop:</font> 4[img]/images/graemlins/spade.gif[/img] 2[img]/images/graemlins/diamond.gif[/img] 8[img]/images/graemlins/diamond.gif[/img] ($155.5, 3 players)

Plan?

In the hand I bet $125, CO called and JPeg shoved for $350 total.

Note that CO and I are 250bb deep.
