What is Double Down in Blackjack?

In the world of blackjack, “double down” refers to a strategic move where a player decides to double their initial bet after receiving their first two cards. By doing so, the player can draw only one additional card to improve their hand’s strength. The option to double down is typically available on the first two cards dealt, and it’s a popular move used by players to increase their potential winnings when they believe they have a strong hand.

How Does Double Down Work?

When you decide to double down, you need to match your original bet with an additional bet of equal value. The dealer then deals one more card face down, which you can’t view until the end of the round. It’s important to note that when you double down, you commit to standing after receiving the additional card, meaning you cannot request any more cards for that particular hand.

When should you Double Down?

Knowing when to double down is crucial to maximizing your chances of winning in blackjack. Here are some situations where you should apply this type of bet:

  1. Strong Starting Hand: When your initial two cards total 9, 10, or 11, and the dealer’s upcard is weak (2 to 6), it’s an ideal scenario for doubling down.
  2. Soft Hands: When you have an Ace in your hand (which can be counted as 1 or 11), doubling down can be advantageous.
  3. Card Counting Strategy: Advanced players who employ card counting techniques may choose to double down based on their card count and the remaining cards in the deck.

Hand Value

The player’s hand value plays a significant role in determining when to Double Down. It is generally advisable to Double Down when the player’s initial hand totals 9, 10, or 11. These hand values offer a good chance of improving without exceeding 21, especially when the dealer’s upcard is weak.

Dealer’s Upcard

The dealer’s upcard is another critical factor in the decision-making process. If the dealer has a weak upcard, such as 2 through 6, it increases the likelihood of them busting. In such cases, players can take advantage of this favorable situation by opting for Double Down and potentially doubling their winnings.

Game Strategy

The overall game strategy should also guide the decision to Double Down. It is essential to consider the specific blackjack variant being played and adjust the strategy accordingly. Different game variations may have slightly different rules and probabilities, impacting the optimal Double Down opportunities.

An Overview of the Pros and Cons of Double Down

Double down can be a powerful tool in a blackjack player’s arsenal, but it also comes with risks. Let’s explore the advantages and disadvantages:

  • Increased Winnings
  • Capitalizing on Strong Hands
  • Psychological Impact
  • Increased Risk
  • Vulnerability to Bust

Advantages of Double Down

Utilizing the Double Down option can provide several advantages for blackjack players. Some of the key benefits include:

Increased Winnings

By doubling the initial bet, players have the opportunity to 2x their potential winnings. When executed in favorable circumstances, Double Down can significantly boost the player’s profitability.

Pressuring the Dealer

When players Double Down in situations where the dealer’s upcard is weak, it puts additional pressure on the dealer to make strategic decisions. This can result in the dealer making mistakes and ultimately benefit the player.

Confidence Boost

Double Down is not only a strategic move but also a psychological one. By opting for Double Down, players showcase their confidence in their hand and their ability to make profitable decisions. This confidence boost can positively impact the player’s overall gameplay and mindset.

Risks of Double Down

While Double Down presents opportunities for increased winnings, it also carries inherent risks. It is essential to be aware of these risks before utilizing the Double Down option:

Potential Losses

When a player chooses to Double Down, they are effectively doubling their bet size. If the additional card received does not improve the hand or leads to a bust, the player loses twice the original bet amount. This risk of losing a larger bet should be considered when deciding whether to extra bet.

Bust Potential

Doubling down on certain hand values can increase the risk of busting. For example, doubling down on a hard hand value of 12 or higher can be risky, as the chances of exceeding 21 and losing the hand are significant. Players should carefully assess the probabilities and weigh the potential risks before opting for Double Down.

Strategies for Doubling Down

To increase your chances of success, it’s essential to adopt effective strategies when choosing to double down. Here are some popular strategies to consider:

  1. Basic Strategy: Familiarize yourself with the basic strategy charts that outline the optimal times to double down based on your hand and the dealer’s upcard.
  2. Card Counting: Advanced players who are proficient in card counting techniques can use their count to determine the most opportune moments to double down.
  3. Bankroll Management: Set specific limits for doubling down to ensure you don’t exhaust your bankroll too quickly.

Soft Hands

When the player’s hand contains an Ace that can be counted as 11 without exceeding 21, it is known as a soft hand. In such cases, the general strategy is to Double Down more frequently, especially when the dealer’s upcard is weak. The combination of a soft hand and a weak dealer upcard creates an advantageous scenario that can be capitalized upon.

Hard Hands

Hard hands refer to hands that do not contain an Ace or hands where the Ace can only be counted as 1 to avoid busting. When dealing with hard hands, players should consider doubling down when their hand value is 9, 10, or 11. This strategy aims to increase the bet size and potentially improve the hand value without risking too much.

Common Mistakes to Avoid

While doubling down can be a valuable tool, it’s crucial to avoid common mistakes that can diminish your chances of success. Here are some pitfalls to watch out for:

  1. Doubling Down on Weak Hands: It’s essential to resist the temptation to double down on hands that have a low probability of winning.
  2. Ignoring Basic Strategy: Ignoring the basic strategy charts can lead to poor decision-making when it comes to doubling down.
  3. Doubling Down with Insufficient Bankroll: Ensure you have enough funds to support your doubling down decisions and avoid risking more than you can afford to lose.

Double Down Variations

Apart from the traditional double down, some blackjack variations offer additional options. Here are a few notable variations:

  • Double Exposure Blackjack: In this variant, both of the dealer’s cards are dealt face up, giving players additional information before deciding to double down.
  • Spanish 21: In Spanish 21, players can double down on any number of cards, even after splitting, which provides more flexibility.
  • Super Fun 21: This variant offers liberal double down rules, allowing players to double down on any number of cards.


Double Down is a powerful move in the game of blackjack that can significantly impact your gameplay and potential winnings. By understanding the concept, following a sound strategy, and avoiding common mistakes, you can enhance your blackjack skills and increase your chances of success. Remember to assess the specific scenario, consider the rules and probabilities, and exercise disciplined decision-making. With practice and a solid understanding of Double Down, you can take your blackjack experience to new heights and enjoy the thrill of this exciting game.
