AA facing shortstack all-in with one player behind

[Sotiria]

CO is a typical bad short stack micro player, no reads on the other villain.

Obviously, the short stacks all-in is an insta-call if there isn't another player to act. BB's cold call on the flop isn't that odd, but when it's followed by a cold-call on the turn, it's really really suspicious.

Now, this hand might seem pretty standard, but I *know* a ton of you uNL players have trouble getting away from AA or KK just because the quality of play is so atrocious that it's easy to put both players on a queen, a club draw + pair, J10, or even a naked club draw. I'm almost certain that the short stack has a pair of queens, JJ or 1010.

So wtf do I do.
