NL100 : AA on monotone board vs 2 opponents

[sccl]

SB is 17/7, no read on CO except that he buys in with $27.55.
I checked the flop hoping that the shortstack will shove and SB will fold. Unfortunatly, he called... what should I do now ?
Does some of you think leading the flop is better ? If so what's the plan if SB call, checkraise ?

i fold, too drawy, and youre nowhere near pot committed, theres a good chance someone has/will have at least two pair with this board

Easy fold

[Jurrr]

I think it's a fold; anything else is playing this for stacks and I don't think you really want that.

I mean SB probably knows you will come over the top if you have an overpair/TPTK with a [img]/images/graemlins/diamond.gif[/img] or a set and he gets no implied odds from the CO so it's not that likely he is drawing.

Slightly ahead or way behind, muck it.

[BlueBear]

The presense of another caller makes this a fold.

I think you could be slightly ahead of the all-in bet of CO (AQ, something with the ace of diamonds, maybe KK), but the call of the other stack is just inviting you to come along. I think I would fold this near 100%, you have a weak hand at this board, little invested, no chance of improving.

I saw this hand to a friend who asked me if I have ever fold AA...
He didn't understand why I fold and told me he would have push the flop.
Shortstack can have ATC and it's pretty unlikely that villain has a made flush. I did fold, but what do you think of this reasoning ?
