Surrender is a blackjack playing option that lets you forfeit your hand and recover half your wager.
After seeing your two-card hand and the dealer's upcard, if you judge your chances of winning to be poor, you can surrender instead of playing the hand out. The dealer removes half your bet, takes your cards, and moves on.
Not every casino offers surrender, and most players instinctively avoid it, but used correctly, it's the mathematically correct play in a handful of specific situations.
When Does Surrender Make Sense?
Surrender makes sense when your expected loss on the hand exceeds 50%. Since surrendering always costs you exactly half your bet, the rule is straightforward: surrender only when your chances of winning are below 25% (i.e. you'll lose more than 75% of the time).
Take a hard 16 against a dealer 10, one of the worst situations in blackjack. In a six-deck game, your options break down like this:
- Hit: win 23.4%, lose 76.6% – expected loss of $53.20 per $100 bet
- Stand: win 22.8%, lose 77.2% – expected loss of $54.40 per $100 bet
- Surrender: guaranteed loss of $50.00 per $100 bet
Surrendering saves you $3.20 to $4.40 per $100 compared to playing the hand. Over time, that difference adds up.
Making Surrender Worthwhile
Surrender strategy depends on three variables: the number of decks in play, whether the dealer hits or stands on soft 17, and the composition of your hand. The sections below cover the most common scenarios.
In the strategies below, "Rh" means surrender if available, hit if not. "Rs" means surrender if available, stand if not. "Rp" means surrender if available, split if not.
Basic Strategy for Late Surrender: Six Decks, Dealer Hits Soft 17
This is the most common rule set you'll encounter in online and land-based casinos.
- Hard 15 vs. dealer 10: Rh
- Hard 15 vs. dealer Ace: Rh
- Hard 16 vs. dealer 9: Rh
- Hard 16 vs. dealer 10: Rh
- Hard 16 vs. dealer Ace: Rh
- Hard 17 vs. dealer Ace: Rs
- Pair of 8s vs. dealer Ace: Rp
Here's the reasoning behind each hand:
Hard 15: Hitting hard 15 against a dealer 10 averages 50.4-50.5 cents with 10-5 or 9-6, and 50.01 cents with 8-7 – all above the surrender threshold, though the 8-7 is a negligible difference. Against a dealer Ace, hitting costs 59.5-59.9 cents depending on composition, making surrender clearly correct. Against a dealer 9, average losses when hitting fall to 46.8-47.2 cents, so you hit instead.
Hard 16: With one more bust card than hard 15 (any 6 through 10 busts you), surrender is correct against a dealer 9, 10, or Ace. Hitting average losses: 50.6 cents vs 9, 53.6-53.7 cents vs 10, 54.0-54.1 cents vs Ace – all above the 50-cent surrender cost.
Hard 17 vs Ace: Normally, you stand on hard 17, but when the dealer hits soft 17, their average final hand improves enough that standing on 17 becomes costly. Surrender if the option is available; stand if it isn't.
Pair of 8s vs. Ace: Splitting 8s is almost always correct, but against a dealer Ace in a hit-soft-17 game, splitting produces an average loss of 51.7 cents per dollar of your original wager – above the 50-cent surrender threshold. Surrender the pair; split only if surrender isn't offered.
Basic Strategy for Late Surrender: Six Decks, Dealer Stands on Soft 17
When the dealer stands on soft 17, you surrender less often. A dealer who stands on soft 17 ends up with a weaker average final hand than one who hits it, which shifts more situations in the player's favour.
- Hard 15 vs. dealer 10: Rh
- Hard 16 vs. dealer 9: Rh
- Hard 16 vs. dealer 10: Rh
- Hard 16 vs. dealer Ace: Rh
Note: hard 15 vs. Ace drops off the surrender list entirely. When the dealer stands on soft 17, hitting hard 15 against an Ace averages only 47.6-48.3 cents in losses, below the 50-cent surrender threshold. You hit instead.
Hard 16 still warrants surrender against 9, 10, and Ace. Average losses when hitting: 50.5 cents vs 9, 53.5 cents vs 10, 51.4-51.6 cents vs Ace.
Basic Strategy for Late Surrender: One Deck, Dealer Hits Soft 17
Single-deck blackjack with surrender is rare. If you find it, check the other rules carefully. Single-deck games often offset player-friendly rules elsewhere.
- Hard 15 vs. dealer Ace: Rh (but hit if your 15 is 8-7 – average loss drops to 48.3 cents)
- Hard 16 vs. dealer 10: Rh
- Hard 16 vs. dealer Ace: Rh
- Hard 17 vs. dealer Ace: Rs (10-7 only; hit with 9-8, where losses fall to 49.1 cents)
- Pair of 7s vs. dealer 10: Rs
- Pair of 7s vs. dealer Ace: Rh
The pair of 7s is the hand to watch in single-deck H17 games. Against a dealer 10, the next best play is to stand, with an average loss of 51 cents. Against a dealer Ace, the next best play is to hit, with a 52.3-cent average loss.
Basic Strategy for Late Surrender: One Deck, Dealer Stands on Soft 17
The surrender list shrinks further. Only two hands qualify:
- Hard 16 vs. dealer 10: Rh (average losses when hitting: 50.7 cents with 10-6, 51.2 cents with 9-7)
- Pair of 7s vs. dealer 10: Rs (average loss when standing: 51 cents; hitting is worse at 51.5 cents)
Don't surrender 7-7 against a dealer Ace in this game. Hitting averages only 49.4 cents in losses, below the surrender threshold.
A Word About Early Surrender
Early surrender lets you forfeit your hand before the dealer checks for blackjack. It's a significantly more favourable rule for players than late surrender, and it's extraordinarily rare. You're unlikely to encounter it outside of certain European and Asian casinos or speciality blackjack variants with offsetting rules elsewhere.
Basic strategy for early surrender:
- Against a dealer Ace: surrender with hard 5-7, hard 12-17, and pairs of 3s, 6s, 7s, or 8s
- Against a dealer 10: surrender with hard 14-16, or pairs of 7s or 8s
For most players, late surrender is the relevant strategy. Focus there, especially in online blackjack, where surrender is more commonly available than at land-based tables.
More Tips for Blackjack Surrender
- To check if a casino offers surrender, look at the rules placard on the table, or ask the dealer. Online, check the game's rules summary before playing.
- In US casinos, surrender is only available after the dealer peeks for blackjack when showing an Ace or 10. If the dealer has blackjack, surrender is off the table, and you lose your full bet (unless you also have blackjack). This is late surrender, the strategy covered in this article.
- To signal surrender at a live table, either announce it verbally ("surrender") or draw an imaginary line from left to right across the felt with your index finger. Casinos vary in which they accept.
- Using a correct late surrender strategy reduces the house edge by approximately 0.07% in multiple-deck games. It also stabilises your bankroll by eliminating the worst expected-value hands.
- For card counters, surrender is especially valuable. Knowing when to surrender based on the count significantly moderates bankroll swings. See Chapter 10.7 in the Ultimate Blackjack Strategy Guide for the surrender "Fab Four" indices.
- Not all online blackjack games offer surrender. Check the game's rules before playing.
