Hit.Why basic strategy says hit
Against an ace, under S17 rules with the dealer having checked for blackjack, the dealer makes strong hands often enough that this profile hits rather than doubles. Under H17 rules the same hand doubles.
Engine explanation: Hit with hard 11 against an ace. Take another card under the selected rules. This is a long-run basic-strategy decision, not a prediction of the next card.

Should I double 11 against a dealer ace?
Not under the rules this site's chart assumes. With six decks and a dealer who stands on soft 17, hard 11 against an ace is a hit, because the dealer finishes strongly too often from an ace to make committing a second bet worthwhile. If the dealer hits soft 17 (H17) the answer flips to double, and in single-deck games you double as well. Against every other upcard, 2 through 10, double 11.
Training rules: six decks · dealer stands on soft 17 · no surrender
This is a separate educational profile. Rules can differ between app tables and other games.
- Six decks. Dealer stands on all 17s, including soft 17.
- US hole card and peek: decisions assume the dealer has checked and does not have blackjack.
- Double any first two cards, including after splitting. Doubling ends the hand after one extra card.
- Split equal card values into at most four hands. Split aces receive one card each; no resplitting aces.
- No surrender. A natural blackjack pays 3:2; 21 after splitting is not a natural.
- Total-dependent strategy. No card counting or expected-value estimates.
