A soft hand is any blackjack total that contains an Ace counted as 11 — A,2 (soft 13), A,3 (soft 14), and so on up to A,9 (soft 20). The Ace's flexibility means you can't bust on a single hit, which changes the entire decision logic compared to hard totals. Soft hands are the rows where casual players hesitate, default to stand, and leak EV. They're also the rows where the chart's doubling opportunities live.
This cheat sheet covers soft 13 through soft 19 (we'll address soft 20 in a sentence and skip soft 21, which is already a 21). The recommendations are for 4-8 deck blackjack with DAS. We note the H17 vs S17 differences where they matter, but everything below assumes H17 unless flagged.
The doubling cluster (soft 13-17)
Soft 13 through soft 17 all share a similar pattern: you double when the dealer is weak (showing 4, 5, or 6 — the bust-card range) and hit against everything else. The exact start of the doubling range tightens as your soft total goes up.
Soft 13 (A,2) and Soft 14 (A,3)
Double vs dealer 5-6. Hit vs dealer 2-4 and vs 7-Ace. The doubling range starts at 5 because soft 13 and 14 are weak hands — you're not doubling for big EV, you're doubling for the table-money advantage when the dealer is likely to bust.
Soft 15 (A,4) and Soft 16 (A,5)
Double vs dealer 4-6. Hit vs dealer 2-3 and vs 7-Ace. The doubling range widens by one card because the hand has more upside on the third card.
Soft 17 (A,6)
Double vs dealer 3-6. Hit vs dealer 2, and vs 7-Ace. Note: you hit soft 17 against dealer 2. Standing on soft 17 is the single most common rookie mistake on a soft hand — soft 17 is a guaranteed-non-bust total, the dealer is going to land 17-20 most of the time, and you have nothing to gain by stopping at 17. Always hit (or double when the chart says so).
The decision cluster (soft 18)
Soft 18 is the most-misplayed row on the chart. Recreational players default to standing on 18 — because 18 is 'a good number' — and lose money on cells where the chart says to hit or double.
- Soft 18 vs dealer 2: Stand (S17) or Ds (H17 — double if allowed, else stand).
- Soft 18 vs dealer 3-6: Ds. Double if allowed, otherwise stand.
- Soft 18 vs dealer 7-8: Stand. You expect to win or push against a dealer 7 or 8 showing.
- Soft 18 vs dealer 9, T: Hit. This is the trap. 18 loses to dealer 19 or 20 — the most likely dealer totals against a 9 or T upcard. Hit to try to draw to 19 or 20.
- Soft 18 vs dealer Ace: Hit on H17. Stand on S17. The dealer's soft-17 hit gives him another shot at beating your 18.
The stand cluster (soft 19-20)
Soft 19 (A,8)
Stand vs everything on S17. On H17, double vs dealer 6 if allowed (else stand). Everywhere else: stand. Soft 19 is a strong hand — the only edge case is the H17 vs 6 double, which is a marginal play most casual players ignore.
Soft 20 (A,9)
Stand. Always. No matter the dealer upcard, no matter the count, no matter the table. 20 is the second-best hand in the game. Doubling or hitting it is throwing money away.
The soft 17 rule, in one sentence
Never stand on soft 17. There is no dealer upcard at any rule set where standing on soft 17 is correct. Either hit or double — never stand.
Why soft hands are hard to play
Two things make soft hands counter-intuitive. First, the Ace's value flips. A soft 17 becomes a hard 17 if you draw a high card on the next hit — but you also can't bust on any single card, which means hitting is always 'safe' in the bust sense. Second, the doubling threshold moves as the dealer upcard changes, which is harder to memorize than the simpler hard-total chart.
The cure is repetition. Drill soft hands in isolation — most chart drilling apps mix them in at their natural ~12% frequency, which doesn't give you enough reps to lock the cells in.
