Hard 11 vs Dealer Ace

Basic strategy says double. Here's what the math looks like across common rule sets.

Why Double Is Correct

Hard 11 against dealer Ace is a doubling play: your starting total is strong enough to warrant the bigger bet even though the dealer busts only 11.7% 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.
