Ace–six and ten–seven both total seventeen. Hit ten–seven with a ten and you bust. Hit ace–six with a ten and you still have seventeen: the ace changes from eleven to one. That difference explains why the two hands belong in different parts of a strategy chart.
A soft hand contains an ace currently worth eleven. It can absorb the next card without immediately busting. The flexibility gives you options, but does not guarantee an improvement. You can turn a soft hand into a hard total that is worse than the one you started with.
This chapter uses our six-deck S17 profile: dealer stands on all seventeens, doubling after splitting is allowed, surrender is unavailable and the dealer checks for blackjack before decisions. The complete chart and trainer use the same rules.
Recalculate the hand after every card
Count all aces as one initially, add the other cards, then promote one ace to eleven if the extra ten points keep the total at 21 or below. At most one ace can count as eleven in a playable hand. Two eleven-point aces already exceed 21.
| Sequence | Result | Next chart section |
|---|---|---|
| Ace, two, four | Soft seventeen | Soft totals |
| Add a nine | Hard sixteen | Hard totals |
| Add a five to that sixteen | Hard twenty-one | Hand complete |
| Ace, ace, five | Soft seventeen | Soft totals if playable |
| Ace, nine, five | Hard fifteen | Hard totals |
Notice that drawing a nine from soft seventeen produces hard sixteen, not twenty-six and not seventeen. The ace’s ten-point adjustment changes the arithmetic. Continue from the new hand rather than repeating the old soft-total answer.
The complete soft-hand pattern
The table describes playable hands after any eligible pair decision. Doubles require exactly two cards. Against dealer upcards not listed in the double column, follow the last column.
| Soft total | Usual two-card example | Double against | Otherwise |
|---|---|---|---|
| 13 or 14 | Ace–two, ace–three | Five, six | Hit |
| 15 or 16 | Ace–four, ace–five | Four, five, six | Hit |
| 17 | Ace–six | Three through six | Hit |
| 18 | Ace–seven | Three through six | Stand against two, seven, eight; hit against nine, ten, ace |
| 19 or 20 | Ace–eight, ace–nine | None | Stand |
An initial ace–ace is a pair and should be split when available; it is not a reason to seek a soft-twelve row. Split aces receive only one additional card each here and then finish automatically.
The S17 pattern is independently documented in the Wizard of Odds multi-deck reference. Its H17 adjustments are a separate strategy, which is why the dealer rule belongs beside every chart.
Why soft seventeen is unfinished
A hard seventeen is already risky to hit. Soft seventeen offers another draw without immediate busting, and standing leaves you unable to beat a dealer eighteen through twenty-one. Under this profile, never stand on a playable soft seventeen: double against three through six if eligible, otherwise hit.
Do not imitate the dealer. The dealer must stand on ace–six in our S17 game. You should hit or double it because your choices and payoff comparison are different from the dealer’s compulsory procedure. “The dealer stands on seventeen” is a dealer rule, not a rule for player strategy.
For example, ace–six against eight hits. A four makes twenty-one; a ten makes hard seventeen; a nine makes hard sixteen. Each outcome has a different continuation, and none changes whether the original hit was correct.
Soft eighteen needs three separate answers
Against two, seven or eight, stand on ace–seven. Against three through six, double when allowed. Against nine, ten or ace, hit. Memorizing only “eighteen is strong” erases all the useful distinctions.
Against a nine, the ability to draw without immediately busting makes improvement worth seeking under this profile. A two or three makes twenty or twenty-one. A ten leaves hard eighteen. A nine leaves hard seventeen. The downside is real, but evaluating only that downside is not a comparison with standing.
Against five, the preferred two-card decision is double. You accept exactly one card while increasing the stake. If the hand is ace–three–four instead, doubling is unavailable, and the fallback is stand. Soft eighteen is the crucial exception to the usual “double if possible, otherwise hit” instruction.
Low soft doubles are about the whole outcome
Doubling ace–two against six can look strange: a ten-value draw leaves thirteen. That observation considers one draw and ignores how the hand subsequently competes against the dealer. A low final total can still win if the dealer busts; a beautiful total can still lose.
The recommendation compares doubling with hitting over the available outcomes. It does not claim the draw must improve the displayed total. Against a strong upcard, retaining the ability to draw again is more valuable; against the specified weaker upcards, this profile prefers the double. The doubling chapter explains the commitment in more detail.
Separate rule changes from memory errors
In a comparable H17 game, soft eighteen against two and soft nineteen against six become doubles. Here they remain stands. Do not import those H17 cells into this S17 trainer. Likewise, a table that restricts doubling to hard totals can remove soft doubles altogether.
Practise ace–six, ace–seven and ace–eight against the same dealer six: double, double, stand. Then practise ace–seven against eight and nine: stand, hit. Finally draw imaginary cards and recalculate softness. Recognizing when the ace stops counting as eleven is just as important as learning the opening decision.
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.
