When to Double Down in Blackjack?

Doubling down in the game of Blackjack allows you to boost your initial bet by 100%. It’s a fantastic opportunity that adds value to your wagering. It enables you to receive one card in exchange for the ability to double your wager in the middle of a hand. It’s a dangerous bet because it typically terminates your betting; even if you get a second card that’s especially low, you can’t hit it again.

This may cause more cautious players to avoid the double bet and more daring players to place it far too frequently. To add to your chances of winning, it’s crucial to balance dangerous double downs with logical, safe play. So, you should utilize statistical methods. Also, it would help if you play online Blackjack at any of the top casinos in your state.

What to consider before a double down in Blackjack?

This method ought to hold in practically all blackjack games. However, consider that there are variations in blackjack regulations among casinos, which may influence your choice. Pay attention to your total because if you can double with three or more cards, you might find more hands where you can double down.

Again, there may be circumstances where you should double down even when the rules forbid it, such as when you have soft hands (those with an Ace). If you cannot double down when you’d like, hit in its place. Before entering a real-world casino, test this double-down method in a cash game.

When to double down?

Fortunately, mathematical probability has been painstakingly used to map out basic blackjack strategy, allowing you to know precisely when it is best (over time) to double down. Below are a few scenarios where it makes sense to double down.

According to statistics, you cannot go bankrupt in any of these scenarios, and you are therefore most likely to end up with a high hand. At the same time, the dealer is most likely to lose the hand. There are some situations where one is advised to use the Blackjack double-down wager.

With a hard 9 or 10.

Only in cases where the dealer is displaying a poor card. If you draw a reasonably high card, you will have a strong hand while playing against the dealer.

Please remember that things won’t always go your way when you double down.

However, if utilized correctly, the strategy will eventually boost your winnings.

When your cards total 11

This is because you have a significant probability of hitting 21. Even if you don’t, you’ll probably obtain a score very close to the elusive 21.

When you have a soft 16, 17 or 18

An ace plus one more card is a “soft” hand in poker. Authority can be a great winner while playing Blackjack, as it increases your statistical possibilities of either hitting or coming extremely close to 21. However, be careful not to overreact when you see that crucial Ace. This is a general rule, and you should only double down in this scenario if the dealer is again revealing a weak card.

In general, you should only double down in this situation if the dealer is showing a worse card.

Although you might be tempted to hold your hand as it is, especially if you have a soft 18, there is a reasonable probability that you can improve it with only one card.

Against the Dealer’s Low Cards, Hard 9

Double down again, the dealer shows a card between 2 and 6, and you are dealt nine (any card below 7, not including the Ace). Since there is no Ace in your hand and this must be a hard 9, the possible combinations are 2-7, 3-6, or 4-5. Standing is preferable if you hold an A-8 (a soft 9) regardless of what the dealer shows.

When it is not necessary to double down?

Here’s one that should go without saying: don’t double down if the dealer is showing an ace.

Simply enough, they have too many chances of getting a blackjack.

It is a good likelihood that they will finish with a total of 21, even if they check and don’t have Blackjack.

Never double down when you have a hand greater than an 11, as the likelihood of losing the entire bet is too great.

It is preferable to just hit or stay with a smaller total and wait for the dealer to lose money.

If you ever doubt whether to double down, choose the safe choice and leave your wager alone.

At a table, you’ll often see some players double down, and they’re typically the ones who are losing a lot of money.

It would be fair if you only took the risk when you’re clearly in the lead rather than on the vast majority of your hands.


When doubling down, there is one critical factor to consider: the casino’s policies. The simplest of these will let you know when to double down.

You can play as usual if you have any other good hands. In most cases, casinos only allow players to double down when they have cards totaling 10 or 11. (unless you have the chance to split, of course).

Pay close attention to the value the dealer must mark up too. Why? This affects their propensity to live past 21.

Most games require the dealer to hit up to 17, but some require up to 16, reducing the likelihood of going above 21.

The higher the likelihood that they will exceed 21, the more you should consider placing a double-down blackjack wager.

When a dealer has dealt an ace or a 10-value card, find out if they check for Blackjack; if they do and the game continues, they don’t have Blackjack.

As a result, you have considerably better odds of winning when you double down.

If they have Blackjack, you’ll be able to tell since the hand will halt there, and everyone will lose “except those who have also got blackjack”.
