A soft 17 in blackjack is any hand totalling 17 that contains an Ace counted as 11, most often Ace-6.
It's called soft because the Ace can drop to 1, so no single card can bust it. That flexibility is why you never stand on soft 17: you either hit or double down, depending on the dealer's upcard.
Soft 17 vs Hard 17: What's the Difference?
A hard 17 has no Ace counted as 11, so its value is fixed. Hands like 10-7 or 9-8 bust on any card from 5 upwards, and the chance of improving is too small to justify the risk. That's why basic strategy stands on every hard 17.
A soft 17 behaves differently. Draw a 5 to Ace-6, and the Ace drops to 1, leaving you on 12 with the hand still in play. Soft 17 can also be built from three or more cards, such as Ace-3-3 or 2-2-Ace-2, and the same logic applies.
Every soft total works this way. Soft 18 is the next step up, and playing soft 18 adds standing to your options because 18 is a stronger finishing total.
How Should You Play a Soft 17?
Never stand on soft 17, whatever the dealer's upcard. Your choice is between doubling down and hitting, and in a six-deck game it works like this:
- Double down when the dealer shows 3, 4, 5 or 6. If doubling isn't allowed, hit.
- Hit when the dealer shows 2, or 7 through Ace.
A low upcard leaves the dealer most likely to bust, so that's the moment to increase your stake. Against 7 or higher, the dealer is more likely to finish on a strong total, and doubling only adds to what you can lose.
Doubling is normally allowed on your first two cards only. If you reach soft 17 mid-hand (say, 2-4 followed by an Ace), hit. Do the same at tables that don't allow doubling on soft hands. After hitting, play your new total according to blackjack basic strategy.
Does Soft 17 Strategy Change With the Number of Decks?
The deck count changes one decision, and it's the dealer 2. The six-deck rule above also holds in double-deck games. In single-deck blackjack, you also double soft 17 against a 2, so you double against 2 through 6 and hit against 7 through Ace.
The difference comes from card removal. With only 52 cards in play, every card dealt changes the make-up of the remaining deck far more than it would in a shoe, and that's enough to turn the dealer 2 into a doubling spot. Check the deck count in the game rules before you apply the single-deck adjustment.
Soft 17 in Blackjack – FAQ
Is A-6 a Soft 17?
Ace-6 is the most common soft 17 in blackjack. The Ace counts as 11 and the 6 brings the total to 17. Because the Ace can fall back to 1, the same hand can also be read as 7.
Why does standing on Soft 17 cost money?
A 17 is a weak finishing total. It can't beat a dealer hand that reaches 17 or more, and at best it ties, so it mostly wins when the dealer busts. Standing is the costliest of the common soft 17 mistakes, because hitting or doubling gives you a chance to improve with no risk of busting on the next card.
