Why Double Is Correct
Hard 11 against dealer 9 is a doubling play: your starting total is strong enough to warrant the bigger bet even though the dealer busts only 23.1% of the time. Any 10-value card gets you to 21, which is hard to beat — the EV math clears the doubling threshold. If doubling isn't allowed, hit.
