Well, the flop bet was a huge mistake, I think, and affects everything else. You bet 400 into a 1500 pot. This is such a weak bet that it is hard to know what the button has. He may have AT or A9, and figures from your weak bet that you missed the flop entirely. Or he could have you dominated. You just don't know, and with AJ you really want to know.

So, if I were you, I would fold to the the reraise on the flop and curse myself for making a terrible bet. Next time, bet over 50% of the pot, something that shows you are serious about the hand. Then you can be pretty certain that a reraise means you are beat.

AJo is a bitch to play out of position.
