Is this kind of limp reraise really scary enough that you'd consider not pushing, and then consider folding to a flop with an overcard? Sure, it could be AA/KK/AK, but it could be a whole mess of other hands, all of which you crush, and want to be getting it all in preflop vs.

I'm new to SNGs too, but this seems like a situation that's begging you to push preflop after his reraise. Don't give him credit for having AA/KK here. As you played it, you gotta shove that flop.

edit: Perhaps a limp/reraise is enough of a tell to talk you into folding this? Some seem to think so. People also seem to give credence to the UTG minraise, and I've seen horrible cards shown down when someone minraises from UTG...
