What Is Doubling Down in Blackjack?

The question of when to double down in blackjack was answered many years ago, and the amazing thing is that the answer still stands true today. Doubling down is one of the most common blackjack terms that means you decide to double down on your original bet, but you will get one more card and must play with the final hand. The idea of using the strategy of double down is to take advantage of a hand that you feel is possibly stronger than the dealer’s. This move can lead to higher payouts when done correctly.

Here is an example: let’s say you get two cards and have a hand 10 or 11, and the dealer shows a weak card such as 4 or 5. This is the best time to double down. If you double your bet and take one more card, you can increase your chances of achieving a higher total than the dealer.

However, it means that if you get the right card; your winning will double up. But, if you go bust, or the dealer wins because you didn’t get the best hand, then you will lose double the amount.

Basic Blackjack Double Down Rules

Whether you’re playing blackjack at a land-based or live dealer casino, some simple blackjack double down rules apply:

•  You can only double down after being dealt your first two cards.
• The next card you dealt will be the final one.
• It is worth noting that the rules for doubling down can vary from one casino to another. For instance, some casinos may not allow doubling down after splitting a hand, while others permit it but with specific conditions.
• Some casinos allow players to double down after a split, while others don’t. Some casinos restrict doubling down only for specific hands, i.e., 9, 10, or 11. Other blackjack casinos allow doubling down for any two-card hand.

When To Double Down in Blackjack: The Optimal Scenarios

Knowing when to double down in no bust blackjack and when this action is profitable, can increase the odds of winning. There are some statistically proven best times you can double down if you want to play with the optimal strategy and reduce the house edge as much as possible. Below are some instances when you can double down:

Hard 9 Against Dealer’s 3-6

If you find yourself being dealt a total of hard 9s, and the dealer’s card indicates something between 3 and 6, then you are in a good position to double down and win against the dealer.

Remember that, when you are playing with a hard 9, you have a high probability of getting a 19 on a hit, which is a very good hand. If the down card is 9, the dealer has a lesser standing hand, and if it is 2, 3, 4, 5 or 6, the dealer must take a second hit and this can lead to a bust.

Generally, it is recommended that players need to make the most of every situation when the dealer is in a disadvantageous spot and has a weak card.

Hard 10 or 11 Against Dealer’s Lower Cards

Hard 10 or 11 are the best hands to double down, and you should do it if the dealer’s up-card is a 2, 3, 4, 5, 6, 7, 8, or 9.

A hard 10 against the dealer’s 2 to 9 certainly puts you at an advantaged position. Moreover, doubling down on your 10 offers a higher positive expected value against all these up cards when compared to hitting eventually.

Seeing a total of 11 among your cards offers players a favorable situation and you should double when the dealer’s cards are lower. 11 offers you a chance with so many 10-value cards in the deck and 9s as well as 8s to make potential winning hands of 19 and 20.

But the only time you should not double on 10 or 11 is if the up card of the dealer matches your total. For instance, if your total is 10 and the dealer’s is 10, don’t double. Similarly, you should not double when you have a total of 11 and the dealer shows an ace.

Soft Hands (Ace + Card) Worth Doubling Down On

You can also consider doubling down on a soft 16, 17, or 18. In simple terms, a soft hand is when one of the cards is an ace. For example, in the case of a soft 16 consists of an ace and a 5. You may decide to double down on such a hand, as the chances of increasing the hand with an additional card is quite high.

Another good example: If a player is having an ace in his/her hand combined with a 5, 6, or 7 — giving a soft total of 16, 17, or 18 — a player can double the bet if a dealer has a card between 2 and 6.

If you have an Ace, offers a protection against busting, letting you hit without fearing exceeding 21. The flexibility of the player’s hand and the opportunity for a better total is worth doubling down.

Double Down After Splitting (if Allowed)

Many blackjack games will not allow doubling down after splitting in blackjack strategy. However, if this move is allowed, it can offer great benefit as it allows you to double down on plenty of high soft hands.

For instance, if you split a pair of 8s, each new hand can be played individually, letting you double down if you think you have a good chance of winning. This is a key benefit in blackjack, as it offers you better flexibility to increase your profits.

When NOT to Double Down in Blackjack

Although doubling down is one of the best blackjack strategies if you use it wisely, you might encounter situations where you should avoid it. Understanding when it is good to double down in blackjack is vital, but also you need to know when not to use this strategy to avoid unnecessary losses. If you make the wrong move can lead to setbacks, so careful consideration is key. Therefore, avoid double down in the following situations:

✅ Hard Hands 12 and Above

There is a high risk when you double down when you hold a hand 12 and above because the chances of the hand going over 21 after receiving the additional card are very high. Depending on the total hand, you can stand or hit.

Moreover, it is even worse when you are dealing with a hard hand 12 without an ace. You would be taking a higher risk doubling down at this point and you might go bust.

✅ When the Dealer Shows Strong Cards (7-Ace)

In blackjack, if a dealer has a strong total hand, you shouldn’t double down with it. You are not likely to improve your hand considerably by doubling down in this situation, as you may risk losing double your money. The best thing to do is to hit hoping for a better card, or to stand, expecting that the dealer will go bust.

It is worth noting that, if the dealer has an ace, you should not double down. Here the dealer has a good chance of hitting blackjack.

✅ When You’re Card Counting with a Negative Count

Card counting is a strategy in blackjack that allows players to know when the advantage in the game shifts in their favour. However, when the true count is negative, the advantage lies with the house. The more negative the count, the more likely you are going to draw a small card when you have a stiff.

Therefore, if the count is high in the negative direction, doubling down would have higher risk. So, when you are counting cards with a negative it affects the doubling decisions significantly.

✅ When You’re Playing With a Limited Bankroll

While doubling down can yield a profit in the long run, it is important to consider your bankroll and betting limits every time. Double down involves doubling your bet, which can increase the potential risk. We advise players to have a sufficient bankroll to bear potential losses during these higher-stakes situations. If the bankroll is limited, doubling down will not offer better profit in the long run. Also, remember not to make reckless bets.

Double Down Strategy Chart

To ensure that you understand the doubling down strategy, we provide you with a double down strategy chart. The strategy chart gives all the possible card combinations at the start of a game. Also, it shows you what you should do or what move to make in every situation to increase your chances of winning.

If doubling down after splitting is not allowed, then we recommend you hit the following values: 2,2 and 3,3 vs. 2 and 3 4,4 vs. 5 and 6 6,6 vs. 2.

Common Double Down Mistakes to Avoid

The truth of the matter is that avoiding common double down mistakes can make all the difference in terms of wins. To maximize your potential profit here are the mistakes you must avoid:

❌ Avoid Doubling Down on Hard 12 or Higher

Doubling hard 12 and above is not the correct play, and it is never even at all close to being the best play, no matter what the count. When you have a total of more than 11 means that one additional card can easily push you over 21.

Doubling down on hard 12 has higher chances of you going to bust, so it doesn’t make sense trying it in this situation. Therefore, when in doubt, you should not double down because doing so can end up costing you in the long run.

❌ You should Not Double Soft Hands Against Strong Dealer Cards

The lower your hand, the further you are away from 21, meaning that you have more chances of busting. You should avoid doubling down if the dealer’s face-up card is 8, 9, 10, or Ace. As explained above, these cards increase the possibility of the dealer having a strong hand. Therefore, you can try doubling down when you have a hard 10 or an 11, even with a strong card from the dealer. But in some cases, it’s good not to.

❌ Ignoring Rule Variations

Each blackjack variation has its rules. Choosing the right blackjack variation is very important to your gambling experience and potential winnings. Understanding of the rules and risk tolerance should play an important role in the decision-making process. 

Also, note that the blackjack rules do vary between casinos, which can affect you in making decisions. You might find situations where the casino rules can’t allow players to double down. If you cannot double down when you’d like, be sure to hit instead. While, many blackjack games will not allow doubling down after splitting. Therefore, be sure to check these rules keenly.

❌ Doubling Without Bankroll Consideration

One of the most common mistakes many players make is being careless with their bankrolls. As a responsible gambler, understanding the importance of bankroll management is crucial to your success.

So, make sure that you have enough to cover your double bets. By doubling down, means you will be required to double your initial bet which also means that you will be losing double the money if not lucky. To make sure that you stay in play for long, you need to set a considerable bankroll and you might make a profit in the long run.
