with really no info, I cannot think of anything but folding here. If I know what tricks were in his repertoire, my decision may be different but I easily give credit here for a K or Q.

Sticking strictly to the information you provided in your post, I agree that this is an easy fold. Other than telling us that this guy is a maniac, I think this scenario calls for folding a large percentage of the time.

Fold. You're not committed to this pot at all.

Even though his instapush is a little fishy. Do you really want to risk your tournament life on this hand? Pick a better spot.

I think it was Hellmuth who said..They are Just Jacks!

That's even his motto for this WSOP. He's trying to rub it off on Gavin Smith but I'm not sure how much GS is buying it.

I don't think that he has a king so the only hand I'm worried about is something with a queen. He probably figures that you don't have a king since two flopped.

I think that it's sort of close actually - I saw a similar hand in a 109 where the flop was AKx and the player first to act pushed. Second guy called with jacks after a long deliberation and pusher turned over tens....
