Had you made this sort of raise and folded to this amount of action previously?
What was your perception of the BB?

If hes your regular player i could fold this.
If hes one of the better players i would have to consider that he might be using your tight image together with the fact that he recently did this to you with AA and figure he could well be isolating lite here.

before i talked myself into the above and put it in i would be considering the rest of the tables stacks and whether there were opportunities (weak players) i felt confident i could still exploit if i folded this.
