Here's my read on it... The possible hands they could be pushing allin with against your huge raise in the cutoff are:
AA, AKs, AKo, AQs, KK (yes another KK), KQs, and QQ.
Of those, the only hand that has you dominated is AA, so the initial impulse is to auto-call, but consider this:
Of the rest of the possible hands, AKs, AKo, AQs, and the other KK, are coinflips.... they could go either way.
You dominate only two hands, KQ and QQ. With ONE allin villain, I think I'd call, but against TWO? What are the odds that you have both hands dominated? Fairly low to nil I'd say.
So it's a coinflip. You ask yourself if at this stage in the tourney it's worth a coinflip to determine your standing in the money or not. I say not. Fold the Kings, take your lumps, and wait for a more opportune moment.
BTW, my prediction is that pco has one of those coinflip hands and Comein has the Aces, leaving you totally dominated, and without the chipstack to cover him, this bet isn't worth it.
