Blackjack Surrender Chart

"Late Surrender" is one of the most misunderstood and underutilized rules in Blackjack. By surrendering, you forfeit play on the hand and give up exactly 50% of your bet. While giving up half your money feels bad, it's mathematically vastly superior to playing out a hand where your expected loss is higher than 50%.

The 50% Rule

Surrender has one clean mathematical test: give up half your bet whenever your expected loss from playing on exceeds 50 cents per dollar. That only happens when your win probability (counting pushes as half) drops below 25%, which is why the list of correct surrenders is so short. Everything else, including hands that feel hopeless like 14 vs 10 or 16 vs 8, stays above the threshold. Playing on loses less than half the bet, so surrendering those hands gives money away.

For a hand-by-hand walkthrough of the two textbook cases, including what to do when the table offers no surrender, see 16 vs 10 and 15 vs 10.

When to Surrender, by Table Rules

The surrender list depends on how many decks are in play and whether the dealer hits soft 17. Every row below is computed from the same strategy engine that powers our charts and trainer, assuming late surrender and double after split.

Table rules	Surrender these hands
4-8 decks, dealer stands on soft 17	Hard 15 vs 10 Hard 16 vs 9, 10, Ace
4-8 decks, dealer hits soft 17	Hard 15 vs 10, Ace Hard 16 vs 9, 10, Ace Hard 17 vs Ace 8,8 vs Ace
Double deck, S17	Hard 15 vs 10 Hard 16 vs 10, Ace
Double deck, H17	Hard 15 vs 10, Ace Hard 16 vs 10, Ace Hard 17 vs Ace
Single deck, S17	Hard 15 vs 10 Hard 16 vs 10, Ace 7,7 vs 10
Single deck, H17	Hard 15 vs 10, Ace Hard 16 vs 10, Ace Hard 17 vs Ace 7,7 vs 10, Ace

"Hard 16" means any two-card 16 such as 10-6 or 9-7. A pair of 8s is not played as a 16: split it instead, except where the chart above lists 8,8 as a surrender.

What Changes the List

In the most common game, 4-8 decks with the dealer standing on soft 17, you surrender hard 16 against a 9, 10 or Ace, and hard 15 against a 10. That is the list most printed charts show.

Dealer hits soft 17: the dealer's Ace gets stronger, so hard 15 and hard 17 also surrender against an Ace. Surrendering a made 17 sounds absurd, but against an H17 Ace the dealer ends on 18 or better so often that a flat 17 wins under 25% of the time. Check whether your game is S17 or H17 before you sit down.
Fewer decks: in single and double deck games, hard 16 against a 9 is no longer a surrender. Single deck adds 7,7 against a 10, because the two 7s you hold are cards that would have helped you. See the full single deck and double deck charts.
No surrender at the table: fall back to the standard hard totals strategy, which hits these hands.

For card counters, surrender indices are among the most valuable deviations. 15 vs 10 becomes a "play on" (hit) at negative counts (below 0), and hands like 15 vs 9 become surrenders as the count climbs. The deviations guide covers the index numbers.

Late vs. Early Surrender

Late Surrender: You can only surrender after the dealer checks for blackjack under a 10 or Ace. This is the standard rule found in most casinos today, and the one the chart above assumes.
Early Surrender: You can surrender before the dealer checks for blackjack. This is highly favorable to the player but extremely rare in modern casinos.

Frequently Asked Questions

How do you signal surrender at a live table?

Say 'surrender' clearly and draw a horizontal line behind your bet with your finger. Many casinos require the verbal call because there is no universal hand signal. The dealer takes half your bet and removes your cards, and you are done for the round.

Why do you split 8-8 against a 10 instead of surrendering?

Playing 8-8 as a hard 16 loses about 54 cents per dollar, worse than the 50 cents surrender costs. But splitting into two hands that each start from 8 loses only about 48 cents per dollar in typical games, which beats both. Surrender is only correct when no better escape exists, and for 8-8 one does.

Does surrendering too often mark you as an advantage player?

Basic strategy surrender is only two situations, so it draws no attention. Surrendering a wide range of hands, especially in obvious sync with bet jumps, is a counter tell that pit staff know. Casual players barely use the option at all, which is exactly why using it correctly is free money.

How much does late surrender reduce the house edge?

Correctly used late surrender is worth about 0.07% to 0.09% in a 6-deck game, more when the dealer hits soft 17. That sounds small, but it is one of the largest single-rule improvements available to a basic strategy player, and it costs nothing but knowing two rows of the chart.
