In Part 1, I summarized the differences in playing rules between playing blackjack in U.S. vs. abroad, specifically focusing on the no-hole-card rule. In this article, I will discuss the surrender rule.

The mathematics of surrender is pretty straightforward. You should surrender a hand when your chance of winning is less than one out of four hands (i.e., your expected loss is worse than 50%). This means that statistically, if playing the hand has less than a 25 percent chance of winning (and consequently greater than a 75 percent chance of losing), you will save money in the long run by surrendering the hand instead.

There are two types of surrender: “late surrender” and “early surrender.” The former is more prevalent in U.S. casinos, while the latter is more prevalent in casinos abroad.

## LATE SURRENDER

With late surrender, you can only surrender your hand after the dealer peeks at her hole card when she shows an Ace or a ten, to determine if she has blackjack. If she has blackjack, the surrender option is no longer available, and you will lose your entire bet (unless you also have a blackjack).

The basic playing strategy for late surrender in multiple-deck games where the dealer stands on soft 17 can be summarized in the following two blackjack rules:

1. Surrender hard 16 (but not 8, 8) against dealer 9, 10, or Ace upcard.
2. Surrender hard 15 (but not 8, 7 unless 8-deck) against dealer 10 upcard.

When you use the above late surrender strategy correctly, it will reduce the house edge by about 0.07 percent in multiple-deck games. That doesn’t seem like much but anything you can do to reduce the house edge is a step in the right direction.

## EARLY SURRENDER

Early surrender is rarely offered in U.S. casinos and is more prevalent in European and Asian casinos where dealers do not take a hole card until after all players have acted on their hands (European no-hole-card rule). With the early surrender option, a player can surrender his hand to a dealer’s Ace and/or ten-value upcard before she checks to determine if the casino dealer has a blackjack. Early surrender is a much more favorable rule for players than late surrender. (In a six-deck s17 game, early surrender against the Ace, gains you 0.39 percent, and against the 10, it’s 0.24 percent.)

The basic playing strategy for early surrender in a multiple-deck game (S17) is different from the strategy for late surrender. When early surrender is offered, you should surrender these hands:

1. Against a dealer Ace, surrender hard 5 to 7 (including 3s), and 12 to 17 (including 6s, 7s, and 8s).
2. Against a dealer ten, surrender hard 14 to 16, including 7s and 8s.
3. Against a dealer 9, surrender hard 10-6 and 9-7 (but not 8s).

Note that in some European and Asian (especially Macau) casinos, you can only surrender against a dealer’s ten upcard (not against the Ace).

Besides lowering the house edge, early and late surrender also have this benefit: they will stabilize your bankroll (meaning surrender will flatten the fluctuations in your bankroll) compared to a game where surrender is not offered and you have to play all your hands to completion.

If you happen to be a card counter, you should definitely be using the surrender strategy indices because it will moderate the negative swings in your bankroll; and more importantly, if you are using a decent bet spread, surrender is worth at least three times as much as the 0.07% to a counter (often even more). (For a list of the “Fab 4” strategy indices, see Chapter  10.7 in my Ultimate Basic Strategy Guide.)

Surrender is one of those rare benefits that casinos offer players, so take advantage of their generosity, especially if you play blackjack abroad, and learn when to surrender.
