What Is Double Down In Blackjack?

Understanding what is double down in blackjack is key to mastering the game. This blog post explains how this strategy works, when to use it, and why it can increase your winnings. Learn the risks and benefits of doubling down to improve your blackjack skills and make smarter betting decisions.

What Does Double Down Mean In Blackjack

To double down in blackjack means to double your original bet after receiving your first two cards. When you double down, you place a second bet equal to the first one, and the dealer gives you only one card — then you must stand. It’s a bold move usually made when you have a strong starting hand (like a total of 10 or 11).

Example:

You’re dealt 9♠ and 2♦ (total = 11). You double down by adding another bet. The dealer gives you one card — say, a 10♣ — bringing your total to 21.

When To Double Down In Blackjack

The best time to double down is when you feel the odds are in your favor — when your hand looks strong, and the dealer seems weak. Here are a few great moments to go for it:

• When you have 11. This is the perfect spot to double down. Why? Because there’s a good chance you’ll get a 10 and hit that sweet 21.
• When you have a hard 9 or 10. A “hard” hand means there’s no Ace involved. If the dealer is showing a low card (like 2 through 6), they’re more likely to bust.
• When you have a soft 16, 17, or 18. A “soft” hand includes an Ace, which gives you more flexibility. If the dealer shows a 3 to 6, it might be a smart move to double down and put the pressure on.

When Not To Double Down

Avoid doubling down in blackjack when the dealer has an Ace or a strong upcard (9 or 10). Never double down with a hard 12 or higher, as you risk busting. A soft hand above 18 also isn’t ideal, as one more card is unlikely to improve your total.
