• First, let’s take a look at what doubling down means in blackjack. Essentially, it is a wagering option that gives you the chance to double the value of your initial bet, but you must stand after taking one additional card.
• Once you receive your first two cards, Doubling down means that you are doubling your initial bet. You need to check out the Blackjack rules of the particular game before doubling down. Some land-based casinos allow players to double down for less, such as not having to put down the same amount as the initial bet.

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.

In blackjack, double down is when you actually double the wager when you get the first two cards. As the cards are dealt out, you will have the option if permitted by the rule. In case you win the bet, you will win double your actual wager.

Double Down in Play

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:

• The total points value of your current hand
• The dealer’s up-card
• The house rules and edge
• The version of blackjack being played

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%.

Why Double Down In Blackjack

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.

Blackjack is one of the most widely played games in any casino, brick-and-mortar or online. The game is popular for many reasons, including the fact that it is one of the easiest casino table games to learn to play and offers plenty of strategically-based decision-making to enhance winning opportunities.

While the most common decisions you would make in each round of blackjack include knowing when to hit or when to stand, other crucial strategic decisions include knowing when to split and when to double down.

Splitting Cards – What Is it and When Should You Do It?

The opportunity to split cards usually occurs when any player is dealt two identically-ranked cards, known as a pair, in the initial deal. The player can then split them into two new and separate bets and request another card for each. The two new hands will then each get a full bet, the same as if it were just a single blackjack hand.

Should it be on any two same-ranked cards, or is there a better way to go about splitting cards?

As a matter of fact, there is, and it’s loosely referred to as the aces and eights “rule.” In the case of a pair of aces, the player can either see the hand as a 2 (total), which is very bad, or as a soft 12, which can be just as bad. However, if the player splits the aces into two new bets, they automatically give themselves two separate opportunities to potentially hit a 21 or blackjack.

Similarly, if a player receives a pair of eights in their initial round, it adds up to a total of 16, which is considered to be one of the worst hands in blackjack. However, splitting the eights gives the player an opportunity to build on both hands.

If the player should receive either a 10 card or an 11 card, they will have a total of 18 or 19, which are both much better than going up against the dealer with a total of 16 only, should they choose not to split.

Double Down – What Does It Mean?

As the name implies, doubling down entails doubling your initial bet once you have received your first two cards. Of course, doubling down also depends on the rules of the particular game of blackjack that you happen to be playing.

It is always a good idea to ensure that you can double down in the game of blackjack you want to play before actually sitting down (or playing online). The double-down can be risky since you are putting down twice as much on your hand. If you lose, you lose twice as much. However, if you win, you instantly double your profits for very little extra work.

How the Double-Down System Works

To get your double-down going, you will need to signal to the dealer that this is your intention. In order to do this, simply place the same amount of chips next to your original bet. This is generally the accepted signal for a double-down in most brick-and-mortar or online casinos.

Some land-based and online casinos will also allow you to double down for less, meaning that you can still pull off a double-down move, but you won’t have to put down the same amount as your initial bet, a bit like a special deal.

Once the dealer has acknowledged your wish to double down, he/she will then place an additional card across your initial two cards. This is where the entire double-down procedure ends, as you will not be allowed to do anything else with this hand. In other words, whatever your total hand is with the three cards is the hand you will be playing, without any additional hits.

Letting the Dealer Know You Are Doubling Down and Not Splitting

In blackjack, the action for a double-down is exactly the same as the action for a split. This is usually not a problem if you are either doubling down or splitting. However, if you want to double down on a pair, you will need to let the dealer know that you are doubling down and not splitting the pair.

In order to do this, you will need to say the words “double down” when placing your additional bet. This will ensure that the dealer does not confuse your intention.

Letting the Dealer Know You Are Doubling Down and Not Splitting – Online

Of course, if you are playing blackjack online, you cannot actually say the words “double down” to the dealer since the dealer is effectively a computer program. However, you can simply hit the double-down button (in most instances of online blackjack), and your additional bet will be placed automatically.

Know the Rules

Not every game of blackjack will allow you to double down on your hand, and not every casino (brick-and-mortar or online) will follow the same rules regarding doubling down. The most common form of the double-down rule allows players to double down on their initial two-card hand. Let’s look at some variations of the blackjack double-down rule:

• The most common double-down rule covers your first two-card hand
• Some casinos will also allow you to double down on a blackjack
• Some casinos will restrict the double-down option to either hard 9, hard 10, or hard 11 – this means that your initial two-card total must be 9, 10, or 11
• Players can also double down after a split – this applies to most brick-and-mortar as well as online casinos

When to Double Down?

Doubling down is an enormously popular strategy in blackjack, and it is used by experienced players to potentially increase their profits very quickly. However, as with any technique or strategy, it is important to know what it is and when to use it for best effect.

There are inherent risks with using the double-down betting option that should be considered as well before attempting to use it in a real money blackjack game. While it does have the potential to instantly double your profits, the reverse is also true in that you could instantly lose twice as much as you would if a regular bet ended up as a bust.

When to Use It Strategically

One of the great things about playing blackjack is that there are plenty of opportunities to employ strategies to help improve your chances of success. Many experienced blackjack players also apply strategy to the double-down betting option, which can be combined with a card-counting technique for added effectiveness.

However, if you’re a novice blackjack player and wish to use the double-down betting option in your next blackjack game, you can simply follow these basic double-down guidelines:

• Double down on 11: if your initial two-card hand totals 11, you should probably double down. One of the main reasons for this is that there is always a good chance that you will receive a 10 card as your third card, giving you an instant total of 21
• Double down on a hard 10 if the dealer shows a 4, 5, or 6
• Double down on a hard 9 if the dealer shows either a 5 or a 6

Double Down in Card Counting

Card counting is one of the most notorious blackjack techniques for all the wrong reasons. Many people believe that this is a form of cheating, but in reality, it is just a smart way of figuring out what the blackjack deck may be holding.

The way that card counting works is actually quite easy to understand. Different cards in the deck are given a value, either a minus value or a positive value (-/+), to determine what the deck may be holding. A negative deck, therefore, means that most of the cards in the deck will be low-value cards, while a positive deck tells you that there are more high-value cards still to play.

Card counting can, therefore, be used to determine when to double down and when to avoid the option. If the deck is quite negative, it tells you that doubling down could be a bad idea. For instance, if you have a two-card total of 11, you would probably normally double down in hopes of receiving a 10 card.

Rules Of Blackjack

On a negative deck, there is more of a chance of getting a low-value card such as a 4, 5, or a 6. If the dealer is showing a 10 card, your chances of losing your double-down bet are much higher.

Being Safe with Double Down in Blackjack

As you can see, the double-down technique can be very effective in providing instant double profits, should everything go right. However, there is always the chance that things could go horribly wrong (there are no guarantees in blackjack), and you could lose twice as much.

Blackjack Double Down Strategy

Ultimately, it is all about knowing as much as you can about the game, applying a solid blackjack strategy such as card counting, watching the dealer to see what he is showing as well as what he may be hiding with his hole card, and watching other players to see how strong their hands are (which could tell you how strong or weak the deck is).
