Button raises and you have TT or AQ in the BB. I would reraise this practically every time. I would push unless the money was deep.

If the button is a loose raiser, you can reraise (or stop-and-go if real short stacked) with almost anything.

At low buyins early in a tournament, the play can be real loose and a button raiser can expect to be called. Also people may not adjust their raising standard enough for position. So in this case, a late position raiser may be more likely to have a real hand, so I would be careful about playing back. However, I would still reraise with TT or AQ.
