As the blinds climb, a button that's been stealing relentlessly opens again. You're in the big blind with A♦9♦.

A habitual button stealer opens; you hold A♦9♦ in the BB. Best?

WhyRe-steal. Against a button opening far too wide, a three-bet folds out most of his range, and A-9 suited is a fine semi-bluff with blockers and playability when called. Flatting out of position is the weakest option, and folding lets him run you over.
What happensYou three-bet to 2,700; the wide button folds.  You take it back.
You fought back against a relentless stealer with a re-steal three-bet - a move powered by his wide range and your fold equity, not by your cards.

Re-steal against players who open too often - a three-bet from the blinds prints when their opening range can't withstand pressure.
