Soft 17

Soft 17 is any hand totaling 17 where an Ace counts as 11. The hand is "soft" because the Ace can drop to 1 without busting on the next card.

• Ace-6 — the canonical soft 17. Ace counts as 11; 11 + 6 = 17.
• Ace-2-4 — soft 17. Ace as 11; 11 + 2 + 4 = 17.
• Ace-3-3 — soft 17. Same logic.
• Ace-A-5 — soft 17. One Ace as 11, the other as 1; 11 + 1 + 5 = 17.

If you're holding a soft 17 and draw a 5, the Ace drops from 11 to 1, giving you a hard 12. You can never bust on the next card from a soft hand.

The dealer's behavior on soft 17 is one of the most impactful blackjack rules:

• S17 (dealer stands on soft 17): The player-friendly version. The dealer settles on 17.
• H17 (dealer hits soft 17): The dealer continues drawing. Adds ~0.2% to the house edge because the dealer can improve to a higher total.

Always check the table placard or the printing on the felt before sitting down. The rule is usually displayed prominently. H17 tables are common in regional casinos; S17 is more common on the Las Vegas Strip.

H17 vs S17 changes a handful of player decisions:

• Hard 11 vs dealer Ace — double in H17, hit in S17
• Soft 18 vs dealer Ace — hit in H17, stand in S17
• Soft 19 vs dealer 6 — double in H17, stand in S17
• Hard 17 vs dealer Ace — surrender in H17 if late surrender allowed, stand in S17

Of the 7 table presets in Blackjack Navigator Pro, three use S17 and four use H17. The Strategy Explorer adjusts automatically when you switch presets, so you see the correct play for each rule combination side by side.
