I too would have pushed. It is a $5 tourney and if he has AA, another one starts in another minute. If this is the WSOP and I plunked down $10,000 and it is this early in the tourney, I would have folded.

Sorry, I should have clarified.
There is absolutely no chance I lay this down.
I was wondering if anyone would jab back with a smaller raise, or if all-in here is the consensus play when reraised PF with AA/KK.
