what is the purpose of your raise? your not trying to fold out better hands.. your sitting there fairly sure you have the best hand... call. raise/fold seems bad...

your hand strength is fairly hidden from the flat call from the button with what should be a fairly wide range in the eyes of the villian..

with that in mind, its very plausable villian does this with weaker aces, especially if he thinks u may be playing your position, and raising what is a perfect flop for him to cbet air like broadways..
