renton, this seems somewhat standard against an even reasonably aggressive opponent. I think it's played fine against an unknown. If you're just calling the flop raise with a hand as good as AA here then he can profitably raise so many hands behind (assumes you're folding most weaker hands and everything that blanked). Worst case scenario, you're up against a set on the flop and still have 12-13% equity, but there are so many other hands that he can have that you can get value from.
