I can well remember the good ol’ days in Atlantic City when casino gaming first began there. The one casino that was open at the time (Resorts International) had to offer a Blackjack game where the rules were established by the Casino Control Commission and that included a weird rule called ‘surrender’. At least we thought it was weird until we figured out what a huge advantage it gave to the player who used it correctly!
Most players dubbed surrender as a sucker bet. One time at a table, some other player summed it all up when he declared: “Surrendering is nuts! Why give up half your bet when you could just as easily win the hand?” To a degree, he was right. What I mean by that is it’s true that a player could win or lose any one given hand, but he didn’t carry the thought far enough. If you play thousands of hands, giving up 50% of the bet on some of them is actually the cheaper alternative to playing it out.
For those of you who aren’t familiar with surrender, it’s a player option that some casinos offer. When allowed, you may elect to give up half the amount you’ve bet rather than play out the hand. For the mathematically inclined, you can see that for those hands where your expectation is to lose more than 50% of your bet, surrender is a good deal. (Ignoring pushes, an expected loss of over 50% means you are more than 75% likely to lose the hand.) There are two types of surrender: early and late. Those terms refer to whether or not a dealer checks to see if s/he has a blackjack (when an Ace or 10 is showing) before you may make the surrender decision. In A.C., the type of surrender was ‘early’ which meant that you could give up half your bet before the dealer knew if s/he had a ‘natural’. That came about simply because state regulations didn’t allow ‘peeking’, so a dealer didn’t know what his hand was until all the players had made their playing decisions.
Let me show you an example; assume a 6-deck game with double after split allowed and the dealer must stand on A-6. If I have a hand of 9, 7 and the dealer is showing a 10, my ‘expectation’ is to lose 53.7% of all the money I bet in that situation. If I surrender, I’ll lose 50% of all the money bet in that situation. A modest improvement, but better nonetheless. This makes figuring the basic strategy for surrender very simple. If the expectation is to lose more than 50%, you should surrender instead.
The appropriate use of surrender varies depending on whether the dealer hits or stands on soft 17. I provide both sets of strategies here:
|For 6-deck games where the dealer STANDS on all 17s:|
|Player’s hand of 9,7 or 10,6:||Surrender against a dealer 9, 10, Ace.|
(Don’t surrender a pair of 8s. Split them instead.)
|Player’s hand of hard 15:||Surrender against a dealer 10.|
|For 6-deck games where the dealer HITS Soft 17:|
|Player’s hand of hard 15:||Surrender against a dealer’s 10, Ace|
|Player’s hand of 9,7 or 10,6:||Surrender against a dealer 9, 10, Ace.|
|Player’s hand of 8, 8:||Surrender against a dealer Ace.|
|Player’s hand of hard 17:||Surrender against a dealer Ace.|
Late surrender adds to the player’s edge by a modest .1%, but I like it when I have a big bet out there and I get a 10 for my first card, as expected, and then get the last 6 in the deck as my next card. Who hasn’t done that before?
If you count cards, the surrender option is an even better deal as the count goes up. If you’ve read and studied my lessons up to this point, you know that in a ‘high’ count situation, the proportion of 10s and faces (and Aces) in the remaining deck(s) versus ‘little’ cards is much greater, so the odds of getting such a card have increased considerably. This is where the value of surrender goes up.
Most surrender available these days is ‘late’ surrender, which means that the dealer checks the hole card if s/he is showing an Ace or 10. If s/he has a ‘natural’, your entire bet is lost and surrender isn’t an option. Knowing that the dealer doesn’t have a Blackjack makes surrender, to some people, a stupid play, but let’s examine the situation a bit closer. Just what kind of hand can the dealer get with a face card showing? First of all, the dealer is going to bust only 23% of the time when s/he is showing a 10 or face as an up card. Secondly, s/he is going to end with a total of 20 or 21 41% of the time! And you think you’re going to beat her with your 16? When the dealer is showing an Ace, and does NOT have a Blackjack, s/he still is going to end with a total of 19 or more 46% of the time and will bust only 17% of the time. That’s why surrender is valid, even if the dealer doesn’t have a Blackjack.
Now, as the count goes up, both you and the dealer have a better chance of getting 10s and Aces. Thus, it’s more likely that you’ll get a 10 card if you hit. So, if you have a hand of 15 and the dealer is showing a 9, s/he has a better chance of having a 10 in the hole and it’s more likely that you’ll hit with a 10. Time to bail! When the true count is 2 or more, surrender your 15s against a dealer’s 9. Against an Ace, surrender 15 at a true of 2 or more, if the dealer stands on A-6. If the dealer is required to hit A-6, surrendering 15 is a basic strategy move. Another good one to remember is to surrender 14 against a 10 at a true of 3 or more.
The use of surrender is, from my experience, interesting from a ‘camouflage’ point of view. As you are hopefully aware, we card-counters prefer to keep our skills concealed since, for some sick reason, casino personnel don’t like counters. Surrendering is actually a fairly sophisticated playing technique, so it’s fair to say that the ‘average’ gambler doesn’t use it. Yet, I want to look like an avaerage gambler in order to conceal my abilty to beat the game. But I use surrender when it’s offered and it really helps when the count is high, I have a big bet out there and I surrender a 15 against a 9 (or a 13 against a 10 – true of 8), because it makes me look like a ‘chicken.’ Most casino personnel think surrender is a ‘sucker’ play anyway, so when they see you giving up half a $200 bet, they think you’ll never make any $$$ at the game. That’s just what I want them to think.
Hello Ken, first of all I would like to thank you for such a wonderful course, my game has come on leaps and bounds since reading it, I have been putting in about 4 hours training in per day for the last month and I have made all the flash cards for strategy deviations and have been learning them at a steady pace, it has occurred to me however that some of the flash cards may not be applicable for the set of rules I play here in the U.K.
European hole card rules
Double after split allowed
Double any two cards
No surrender option
Hello, i’m new at the surrender rule. I’ve been thinking about some strategy that can protect me from some awful situations, and found myself playing in multihand with two hands, one just covering the other one. Can I adapt my range of surrender when i play two hands? for example, i have 13 and 20 against a 9. A surrender in 13, isn’t a good choice? because in many situations, i will be profitable. Thanks in advance.
ken …. in 6d s17 15vs 10 when there is a surrender first choice is surr or hit ?I saw a card that says 15 vs 10 stand at tc +4 and above and in how much – tc you prefer to hit than to surrender ?
15 vs 10, stand at TC 4+ , this is an index of Illustrious 18 @ Blackjack Attack, means you have a hand 15 composed of three or more cards, you should not hit at TC 4+.
Thanks alot ken for your time to answer to my posts abouts the surrender.
after some months now i understand that to beat the game you need to play as much hands/hours most you can because you just exchange money between u and the dealer while playing and as long as you have the small edge you keep some money (edge/profit)of this exchange.its the opossite that the casino makes to the regural player.and we need enough money/units to stay alive in this exhange during the up and downs(standard daviation) to our profit
Ken or some admin !! !please i really need some help here.i try to canculate the bj game that i play so PLEASE when a player can surrender against any card the dealer has except an ace and surrender can be made when no card is delt to the players is this an EARLY or a LATE surrender option.also please the penetration percent is something that changes the avantage or disavntage of the player?i know that poor penetration generates poor and more rare high counts but what about when we try to canculate the adge of the casino
The difference between early and late surrender is what happens when the dealer has blackjack. If you can avoid a dealer blackjack by surrendering, it’s early surrender. In most no-hole-card games (based on your last question I assume this applies to you), what is offered is early surrender, but no surrender is allowed against a dealer ace. But you can indeed surrender against a dealer ten even if the dealer eventually ends up with blackjack.
Penetration affects card counters, but not basic strategy players. The edge of the casino is traditionally calculated using basic strategy, so penetration doesn’t affect this calculation. To figure the edge on your game, since the Strategy Engine doesn’t have an option for ‘Early surrender, but not against Ace’, I recommend you choose ‘No Surrender’ instead. Then reduce the house edge it reports by 0.24%, which is the value of ES10.
Since i descoverd this site i cant stop reading !!!all these great informations.in european black jack no dealers down card “hidden” the surrender option works also here ?i see the diffrences bettwen europe and american b.s cards and i think that the hole point is the hit or no at s17?right?at your opinion whick bj is better for the players u.s or european?thanks for your time to answer !wish i could meat u in real and see how u destroy the cazinos !
so I was wondering about a few things, I cant find a free deviation chart for my game rules… everywhere asks for money any idea where I can get a free one? im looking for 6-8 deck dealer hits soft 17 resplit double after split
also I had one other thing I was over thinking lately when I have a soft 18 vs Dealers 3 4 5 6 I double dealers 7 I stay and vs a 9 10 A I hit I resently just found out im suppose to double vs a 2 aswell, however soft 18 vs a dealers 8 it sez stand, I was thinking I want to be hitting this for a free hit? and isn’t 18 a losing hand? soft 17 vs 7 I hit as a free hit don’t I treat it the same 18 vs 8 ? also uhm… when I have an unnatural soft 18 vs the dealers 2-6 are their different plays for each of these? like uhm.. if I have a A-2 Vs Dealers 4 basic strat sez hit, if I get a 5 and have 8 or 18, do I want to stop there or improve my hand ? I was thinking for some reason I wanted to keep improving it but im guessing im suppose to stay… but is this changed by the count being rich with high or low cards?
With a soft 18 made up of 3 or more cards, obviously you can no longer double, so just use the appropriate fallback strategy according to chart. With (A,3,4) vs a dealer 4 for example, you should stand. The charts from this site show that “DS”, meaning Double if you can, else Stand.
You also asked why you should stand with Soft 18 vs 8. Well, the potential push is a big part of that, but in general try not to worry too much about the “why” of basic strategy. It just works that way. Technically, here are the results with A7v8: Standing returns 0.108 on average, hitting returns only 0.041.
Hello. I am a big fan of surrendering but lately I’ve been thinking… if I have 16 against a dealer 10 and my expectation to lose is 53.7% then. .. if I’m being 100 a hand and I do this 3 times I essentially list $150. Now if I hit and win 1 out of 3 hands (33.3%) I will have $200… so I am up $50 compared to surrendering ($150). Where is my thought process flawed? Please help.
There is nothing wrong with your logic. If you can win 1 out of 3 hands, you should not surrender. The breakeven point is 1 in 4 hands. At that point, you would lose the same amount whether you surrendered all 4 hands or played them all out going 1 and 3. For more, see my article on Blackjack Surrender.
Great site! I am new to bj under 200 hours of study. This site answered many questions and offered great advice. Can you recommend top 5 books that are a must read before I lay my money down?
Three good choices: Blackjack Bluebook II, Knock-Out Blackjack (simpler than HiLo, and darned effective counting system), The Blackjack Zone (free online PDF!).
Don Schlesinger’s Blackjack Attack is the most valuable book I have ever read.
others: The Theory of Blackjack (difficult to understand the mathematical formula if you do not have enough math knowledge )
