Orange zone (M 9). An aggressive button that's been opening relentlessly raises again, and you're in the big blind with A♠8♠.

Orange zone, aggressive button opens, you hold A♠8♠ in the BB. Best?

WhyThree-bet shove as a re-steal. Jamming over a wide button uses your fold equity while you still have it; A-8 suited has blockers and decent equity when called. Calling to play a flop out of position is the trap.
What happensYou jam; the button folds.  The re-steal works.
A re-steal jam in the Orange zone exploits a wide stealer's range with your fold equity - a near-essential play as blinds climb.

Re-steal-jam over habitual stealers while you still have fold equity - it's how a shrinking stack fights back from the blinds.
