Blackjack Double Down Face Down
One of the best and most exciting options available in blackjack is when we have the opportunity to double down on a bet. As a ‘twice the risk, twice the reward’ option, it has the potential to net us a sizeable return, if we know how and when to properly employ such a tactic. As explained on our terminology page, to double is to place another wager on your hand, equal to the amount of your initial bet, in exchange for only one additional card, and the obligation to stand after that one card is dealt.
For example, if you have been dealt a Six and a Four (a total value of 10), you may choose to double your original wager of $100, as drawing a card valued from seven to 11 is a strong possibility and will stand you in good stead to win the hand. If you do win the hand, instead of receiving a $100 profit if you did not double, you will net a return of $200.
Double Down in Play
In this video we cover the options in the game of Blackjack of Doubling Down and Splitting your hands., as well as when it is best to use these tactics.
Doubling is an essential tactic, and if used correctly, helps to lower the casino’s house edge. A knowledgeable player should know when to employ this move for an advantage in the long run, but the decision needs to be carefully considered before commitment, based on a the following important factors:
- Also, if your dealers shown card is either a 10, ace or a face card, it is wise to not double down. If you double down on 10 for example, and your dealers shown card is a 10, it is possible they can hit 21 and you would have lowered your chance of hitting blackjack because you are already set at 20 and don’t want to risk a bust.

If you are playing a game with eight decks and you can double on any total, the house edge is 0.55%. If you can double after splitting, this reduces the house edge by 0.13%, but if you can double only on totals of 10 and 11, this increases the house edge by 0.21%. And obviously we want the lowest house edge possible.
Mastering basic blackjack strategies is key to winning. Here are some guidelines worthwhile remembering in order to maximise our chances and avoid unfavourable odds when opting to double:
Take Advantage of 9, 10 & 11 Totals
The best hands to double down on are considered to be those with a value of nine, 10 or 11. We already have the ideal hand to hit on and end with a strong total with just one additional card. If you find yourself dealt a hand with these totals, consider doubling down to maximise your winning payout. There will always be a risk present in every decision you make, but the key to winning more games than losing is to take advantage of an edge while you have it. If you are hesitant to double down because of the size of the bet and your potential loss, you might be playing at a table with too high stakes.
Don’t Split Fives, Go For The High Five: A common tactic for players who find themselves with low pocket pair hands such as Deuces or Treys is to split them and improve their chances of winning with two separate hands, which is fine. But if you find yourself with a pair of Fives, refrain from splitting and consider doubling. A total of 10 points is a strong position to be in (as explained above), so with a pair of Fives and roughly a 24% chance of drawing a card valued at 10 points on the next hit (to give you a total of 20), doubling is in your best interests. You also have a solid chance of drawing an Eight, Nine or Ace, resulting in favourably high hands of 18, 19, or 21.
The Rule of 9
The ‘Rule of 9’ is an established guideline regarding when and when not to double if you are dealt a soft hand (a hand with an Ace). Knowing when to double with a soft hand is crucial, so it is worthwhile understanding the rule’s instructions which explain how to maximise our chances of winning. As always, these are recommendations and you don’t have to double just because these rules say so.
The ‘Rule of 9’ works as follows: if you hold a soft hand, add the value of the dealer’s up-card with the value of your non-Ace card. If the total value is greater than nine, it is suggested to double down. If the total value is less than nine, proceed to hit instead.
For example, if the dealer’s up-card is a Four and your hand contains an Ace and a Seven, you should double because the total sum would be 11. In contrast, if the dealer’s up-card is a Five and you hold is an Ace and a 3, you should hit, as the sum, according to the rule, is eight. There are a few exceptions to this rule: never double down if the dealer’s up-card is above Seven, as they are in a strong position to beat you. If the dealer is showing a Deuce, don’t double either as the odds favour the dealer. Also, when the dealer’s up-card is a Five or Six, you should double down with a hand of an Ace and a Deuce through to a Six, as you are in the stronger position.
Be Mindful of the Dealer’s Up-Card
It may seem like common sense, but plenty of players often forget to keep the dealer’s up-card in mind before opting to double down. All of the above tactics should be dependent on the dealer’s up-card, and while it’s good to be aggressive, it can be unwise to double with a soft hand if your dealer has a Nine or Ten showing. The worst cards for the dealer are up-cards of a Deuce through to a Six because those cards give the dealer the highest chance of busting, and this is when we should pounce and double down. Dealer up-cards of Five and Six give their hand the highest chance of busting at roughly 42%.
Here are the most commonly recommended hands to double down on, taking in to consideration the dealer’s up-card:
[table id=1 /]
If you are dealt an Ace with a Deuce through to a Seven, this leaves us in a relatively strong position to double (depending on the dealer’s up-card, as specified in the table). If your soft hand is an Ace and an Eight or Nine, then doubling is not favourable; standing is your best bet.
Being dealt an Ace and a Six or Seven is the ideal hand to double down on. Many people may opt to stand with a soft total of 17 or 18 which is fine, but doubling is often advised. As the table suggests, your decision needs to be dependent on the dealer’s up-card. If you do opt to double with a soft 17/18, you have a strong chance of receiving a card valued at 10 (giving you a hard total of 17 or 18) which leaves you in the position you began in, just with the chance to win double the cash. If you are dealt an Ace, Deuce or Trey, you now hold an even stronger total of either 18, 19, 20, or 19, 20 or 21. If you are dealt a Four on the soft-17 hand, that will also leave you with an unbeatable 21. The point is to take advantage of strong starting soft hands, because of the unique value the Ace holds.
Know Which Variant You’re Playing
American blackjack (unlike American Roulette) has more favourable odds for the player, so where possible, play American versions of the game.
American rules are as follows:
– You are not restricted when doubling down; you can have a hand with any value and choose to double.
– You can also surrender at any time, and the dealer must stand on a soft-17.
European blackjack has the following rules:
– When offered the chance to double, you may only do so if your hand totals nine, 10 or 11.
– The dealer must hit on soft-17, and you cannot surrender.
Double Down? So what does Double Down mean in Blackjack and why is it such a popular strategy?
In short, it is bumping up your initial bet by 100% and staying in the game after only receiving one more card. It might seem like a risky strategy and for some doubling their winnings is the main motivator, but there can be some good reasons behind such a bold move.
The beauty about Blackjack Double Down is that there are some useful and well defined rules based on mathematical probability and tested by generations of players.
That said, the calculability of a hand’s success is not a guarantee of its profitability, nor does it rob the game of its excitement.

Blackjack Double Down – A Numbers Game
Firstly, however green you are to Blackjack, we can all agree that the highest number you can sensibly get is 21. Secondly, we’re out to beat the dealer, either by having the higher value hand, or watching them go bust.
From there on in it’s a case of using statistics to your advantage. This means that whenever you’ve drawn one of the lower 6 cards, there remains a high statistical probability that the remaining cards are all more likely to be a help rather than a hindrance.
Equally, when the dealer draws a 4; 5; or 6, they are statistically more likely to go bust. It therefore seems quite reasonable that when these two scenarios are in play, Blackjack Double Down may well be a good payoff.
Jumping the Gun
Sadly, many players can become a little hyper focused, looking at only the dealers hand or their own and basing their decision to Double Down on that one factor.
For example, many players will draw a 9 and Double Down if the dealer has anything other than a 10. This is strategically flawed and will lead to a significant loss over time.
The other ill-judged manoeuvre is for a player to split a pair of 5’s, which in itself is a risk. A sensible rule here is to keep them together and treat them like a 10. That way you stand a better chance when Doubling Down.
Blackjack Double Down Rules
Rules can vary slightly between casinos, but generally Doubling Down can be used after the player draws their first two cards. Some venues, both online and real-world allow Doubling Down on a Blackjack, whilst others can restrict its use to totals of 9; 10; or 11.
Wherever you play, make sure you know the house rules before you play.
Where it is permitted, splitting a hand into a pair and then doubling down can be useful, but as already mentioned, use this with caution.
Once you have signalled your intention to Double Down, you place your wager. Normally this is 100% your original bet, though some casinos will allow a less-than-double additional wager.
Once you have signalled your intention to Double Down, or simply pressed the relevant button in an online casino, only one more card can be drawn for the player, and they are committed to play.
How to Double Down in Blackjack?
Plenty of rookies have come unstuck, learning the various strategies for making a good Blackjack Double Down play, but not paying attention to its execution.
Etiquette and protocol are a must if you’re not going to spoil the atmosphere at the table. Thankfully online gaming has made the embarrassment from a faux pas less of weighty on the ego, however, you could still miss out if you don’t know when to make the right move.
In short, most games expect the Double Down to be executed immediately after being dealt their second card. If you accidentally hit, you’ll miss your chance and that would really be a shame.
History
The question of when to double down in Blackjack is one that was answered back in the 1950’s when Magician John Scarne took the time to work out the mathematics behind the King of Casino games, Blackjack. His work, published in a book ‘Scarne’s New Complete Guide to Gambling’ described the odds and various plays to be able to make the best possible calls.
The amazing thing about his work is that it still stands true today, with the mathematics and odds transcending time and permeating every Blackjack table in the world.
Today there are many Blackjack Double Down charts that simplify the learning process so that committed players can memorise the best plays.
The Strategies
When to double in blackjack is one of the most asked questions about the game. The best advice originates mainly from John Scarne’s work and has been published and republished in various forms. However, a problem arises whenever that advice is shortened or misquoted.
For example, if the player has drawn 11, they should Double Down, or so the rule says. In reality, there are factors that can influence the probability of this being a successful strategy.
The main one being what cards are left in the deck. Now this question is mainly one reserved for card counters who are able to discern whether the remaining deck is negative heavy, i.e. full of low cards, or not.
In this case, Doubling Down could be risky, especially if the dealer is showing a 10 or higher.
In contrast, where the remaining deck is positive, the player can be assured of more 10’s and above in the pack and has the option to play more hands that could result in a 20 or 21.
For those without that card counting knowhow, it’s usually a good strategy to stick to Doubling Down whenever you have an 11.
What are Hard and Soft Hands then?
Terminology is important, so get it right. Hard Hands don’t normally have and Ace unless it is being used as a 1. Soft Hands, conversely will have an Ace being used as either 11 or 1. With this tid-bit of knowledge under our belt, let’s move on…
What to do with a Soft Hand
This primarily depends on what the dealer’s hand is showing. Using the Rule of 9 can offer some guidance. This is where the Player has drawn an Ace and any card from 2 to 7. Where the player’s ‘number’ card and the dealer’s up-card sum up to 9 or more, the player should Double Down.
Two important exceptions to this rule should be heeded. The first is where the dealer’s up-card shows an Ace, the obvious reason being its ability to be played as its lower denomination.
The second is to never Double Down in Blackjack when the deal’s up-card is a 7 or above, again, the odds are not with you. So don’t do it!
Light work for Hard Hands
There are so many opportunities to Double Down it can feel like you can do it any time, but the reality is that you should choose your moment wisely.
When you have a hard 11, always Double Down, it’s too good to miss. You can also take a fairly good risk with a hard total of 10, but don’t ever try it when the dealer has a 10 or an Ace.
Double Down Blackjack Strategy
To Split or not To Split?
Many casinos allow a player to Double Down after they have split their hand. Here the rule is simple, where you have a pair of 5’s don’t touch them.
Treat them like any other 10 and if the dealer’s hand is 9 or less, you would be wise to double down. Any other cards and splitting may be a sensible option.
What the Dealer’s Hand Reveals
The dealer’s hand is key to knowing how to play your own hand, and thankfully there are some statistics on the bust rates for a dealer’s cards.
For example, a Deuce or Three have just under 40% chance of seeing the dealer go bust. Whilst a 4; 5 or 6 raise that probability to just over 40%.
Meanwhile a 7; 8; 9 or 10 only have a roughly 23% chance of working in the player’s favour whilst the Ace gives a dismally low 17% chance of seeing the dealer fail.
These figures can give hope to a player, especially when they know they also have a favourable hand, and underlines the premise of being fore warned is being fore armed!
Double Down – Down
There are unfortunately occasions where a player is unable to Double Down, despite all the signs that it is a good move to make. One may be the house rules as we mentioned before.
One piece of advice from the experts is that whenever you find yourself with a soft hand, i.e. a hand with an Ace, then it is usually more prudent to hit rather than go for the Double Down.
The Hard 9
We’ve already mentioned the propensity for some players to find themselves with a 9 and to jump down the Double Down hole if the dealer has anything other than a 10.
This is flawed thinking. This idea comes from a very valid play in games where you draw a Hard 9.
The important thing to remember is that this has to be in conjunction with when the dealer draws anything lower than a 7, excluding the Ace.
How Much to Bet?
Ultimately, this is a question reserved for the player, but there are two important rules that may help.
Blackjack Double Down Face Down Jacket
The first is never, and this cannot be stressed enough, NEVER Double Down with an additional bet of less than 100%. The whole aim of the play is to maximise on the odds that sit in your favour, so to bet anything less than the maximum allowed is a waste.
Secondly, if the prospect of doubling your bet at a table makes you sweat, even though you know the mathematics is on your side, then you should probably be at a table with lower stakes!
Some Rules of Thumb
It’s usually a good idea to Double Down when:
- The player has drawn 11
- The player has 10 and the dealer has 4; 5; 6
- The player has 9 and the dealer has 5 or 6
- Player has an Ace and any card from 2 to 7 when the Player’s non-Ace and the dealer’s card add-up to 9 or more
- Dealer has a soft 17
- Also, remember that if you have a pair of 5’s; you should not be tempted to split them, it’s better to consider them as a 10
Top Three Plays
Out of all the pieces of advice, there are probably three plays which give the player the best advantage against the dealer.
The first of those is the Hard 9 which we’ve already mentioned. This is an excellent play with a very good chance of success.
The second is a similar Hard 10 or 11. Again these should be used against a lower draw from the dealer. As long as the hand is not made up with an Ace and the dealer’s hand is lower than yours, Doubling Down is a good move to make.
The third of our Top Three is a Soft 16 to 18. As with the previous two hands we’re looking for the dealer to have a low draw. As long as they have anything from 2 to 6 then Doubling Down is going to position the player favourably against the dealer.
Word to the Wise
Doubling Down can seem like an unnecessary risk, and it is true that doing it can make or break your time at the table. However, the strategies and rules for identifying the best times to Double Down are tried and tested.
While you may stand to lose more money on each individual attempt, in the long term, Doubling Down is a sensible strategy as the rewards will more than make up for time you take to practice the techniques above.
Just remember to know the Double Down rules of the casino you’re in as they are likely to place some restrictions on which of the techniques you can use.
This way you can pick the casino with the most favorable rules, and have more opportunity to see and make those Double Down plays.
