This has happened to me twice early on with kings on UB run up against aces.

I know Hopy is tired of hearing my BS on UPF, so I'll spare him too much here. I agree with betting enough to isolate the other players. Ideally, you want to raise 3-5 times the BB (Cloutier says only play AA, KK or AK suited ten-handed, and I tend to play queens-jacks more gingerly as Hopy recommends). If they call, they will have at least an ace. If they re-raise, they probably have AA, KK or AK (maybe AJ). Other than AA, or KK, you are in good shape. Do you push all of your chips in with queens early??? I think the answer is no, particularly if there is an A or K on the flop, you know they caught it.

My 2 cents.
