Be aware that a few players at the table will be aware of how tight you are. That + aggression is why you were stealing blinds. Not just aggression.

On the hand in question, he can put you on AJ becuase he was looking at the whole picture. You're tight and aggro but just called a minraise preflop. That's not how TAggs play QQ-AA. Flop comes with some threats and you go into protection mode. He makes a bad call for whatever reason fish make bad calls then he turns his queen. You just can't sell him that you had any hand other than QJ, 77 and 33 that he's losing to.
