Do you double 11 agalnst 10
Blackjack is a game of strategy, and one of the most debated decisions among players is whether to double down on a hand of 11 against a dealer’s 10. This decision can significantly impact your chances of winning, so it’s crucial to understand the logic behind it.
Understanding the Situation
When you have a hand totaling 11 (e.g., 5-6, 7-4, etc.), and the dealer shows a 10 (10, J, Q, K), you are faced with a critical decision: to double down or not. Doubling down means you double your initial bet and receive one more card.
Key Points to Consider
- Dealer’s Upcard: The dealer’s upcard is a 10, which means the dealer has a strong hand. The dealer has a 77% chance of having a 10 in the hole, resulting in a total of 20.
- Your Hand: You have 11, which is a strong hand for doubling down because there are many cards (2 through 9) that can improve your hand to 13 through 20.
The Mathematics Behind the Decision
Probability of Winning
- Doubling Down: When you double down on 11, you are hoping to draw a card that will give you a total of 17 or higher. The probability of drawing a card that will improve your hand is high (approximately 72.7%).
- Not Doubling Down: If you choose not to double down, you will likely hit your hand, hoping to improve it without busting. However, the dealer also has a high probability of having a strong hand, which reduces your chances of winning.
Expected Value
- Doubling Down: The expected value (EV) of doubling down on 11 against a 10 is positive, meaning it is a mathematically advantageous move.
- Not Doubling Down: The EV of not doubling down is lower compared to doubling down, indicating that you are less likely to win in the long run.
Practical Advice
Basic Strategy
- Always Double Down on 11 Against a 10: According to basic blackjack strategy, you should always double down on 11 against a dealer’s 10. This is because the potential reward outweighs the risk.
Exceptions
- S17 vs H17: In some casinos, the dealer stands on a soft 17 (S17), while in others, the dealer hits on a soft 17 (H17). The strategy remains the same in both scenarios: double down on 11 against a 10.
- Multiple Decks: The number of decks in play can slightly affect the strategy, but the general rule remains: double down on 11 against a 10.
Doubling down on 11 against a dealer’s 10 is a strong strategic move in blackjack. The positive expected value and high probability of improving your hand make it a favorable decision. Stick to this strategy to maximize your chances of winning in the long run.
Summary
- Always double down on 11 against a 10.
- The probability of improving your hand is high.
- The expected value of doubling down is positive.
- Follow basic strategy for optimal play.
By adhering to this advice, you can enhance your blackjack gameplay and increase your likelihood of success at the table.
blackjack double 11 against 10
Blackjack is a game of strategy, and one of the most crucial decisions a player can make is whether to double down. Doubling down allows you to double your initial bet in exchange for receiving just one more card. This strategy can be particularly effective when you have a strong hand, such as an 11 against a dealer’s 10.
Understanding the Situation
Player’s Hand: 11
- 11 is a powerful hand because it has the potential to turn into a 21 (a blackjack) with just one card.
- The possible outcomes for an 11 are:
- Drawing a 10, J, Q, or K: Results in 21.
- Drawing a 9: Results in 20.
- Drawing an 8: Results in 19.
- Drawing a 7: Results in 18.
- Drawing a 6 or lower: Results in 17 or less.
Dealer’s Upcard: 10
- The dealer’s upcard of 10 suggests that the dealer has a strong hand, potentially a 20 if they have a face card or a 10 as their hole card.
- The dealer’s possible hands are:
- 20 (10 + 10 or J, Q, K)
- 21 (10 + Ace)
- 19 (10 + 9)
- 18 (10 + 8)
- 17 (10 + 7)
Why Double Down on 11 Against a 10?
Probability of Winning
- High Probability of Improvement: With an 11, you have a high chance of improving your hand significantly. Drawing a 10 or a face card will give you a 21, which beats the dealer’s potential 20.
- Avoiding Busting: The only way you can bust with an 11 is by drawing a 10, which is a 30. However, the probability of drawing a 10 is relatively low compared to the potential benefits of improving your hand.
Maximizing Profits
- Double Your Bet: Doubling down allows you to double your initial bet, which can significantly increase your winnings if you draw a favorable card.
- Capitalizing on Dealer’s Weakness: The dealer’s upcard of 10 suggests a strong hand, but it also means the dealer has a higher probability of busting if they draw a weak card. By doubling down, you capitalize on this potential weakness.
Basic Strategy and Variations
Basic Blackjack Strategy
- According to basic blackjack strategy, doubling down on 11 against a dealer’s 10 is a strong move. This strategy is based on mathematical probabilities and is widely accepted as the optimal play.
Variations and House Rules
- Soft 11: If you have a soft 11 (e.g., Ace-10), the strategy may differ. In most cases, you would hit instead of doubling down because the Ace can be counted as 1 or 11, giving you more flexibility.
- House Rules: Some casinos may have specific rules regarding doubling down, such as limiting it to certain hands or requiring a minimum bet. Always check the house rules before playing.
Practical Tips
Managing Your Bankroll
- Bet Wisely: Ensure that you have enough funds to double down without risking your entire bankroll.
- Know When to Walk Away: If you find yourself consistently losing after doubling down, it may be time to reassess your strategy or take a break.
Practice Makes Perfect
- Simulate Games: Use online blackjack simulators to practice doubling down on 11 against a 10.
- Learn from Experience: Play in low-stakes games to gain experience and confidence in your decision-making.
Doubling down on 11 against a dealer’s 10 is a strategic move that can significantly enhance your chances of winning in blackjack. By understanding the probabilities and adhering to basic strategy, you can make informed decisions that maximize your profits and minimize your risks.

Blackjack is a game of strategy, and one of the most debated decisions among players is whether to double down on a hand of 11 against a dealer’s 10. This decision can significantly impact your chances of winning, so it’s crucial to understand the logic behind it.
Understanding the Situation
Before diving into the strategy, let’s break down the scenario:
- Your Hand: You have a total of 11 (e.g., 5 and 6, 7 and 4, etc.).
- Dealer’s Upcard: The dealer is showing a 10 (which could be a 10, J, Q, or K).
The Basic Strategy
According to basic blackjack strategy, you should always double down on 11 against a dealer’s 10. Here’s why:
1. Probability of Winning
- Dealer’s Hand: The dealer has a 10 upcard, which means their hole card could be any of the remaining cards (2 through A).
- Your Hand: You have 11, which is a strong hand. Doubling down allows you to maximize your bet when you have a good chance of improving your hand.
2. Expected Value
- Doubling Down: The expected value of doubling down on 11 against a 10 is positive. This means that, on average, you will win more money in the long run by doubling down in this situation.
- Hitting: If you choose to hit instead of doubling down, you risk drawing a card that could bust your hand (e.g., drawing a 10 or face card).
3. Dealer’s Potential Hand
- Dealer’s Bust Probability: The dealer has a 23.34% chance of busting with a 10 upcard. However, even if the dealer doesn’t bust, you still have a good chance of winning if you draw a high card (e.g., a 10 or face card).
Practical Considerations
While the basic strategy is clear, there are a few practical considerations to keep in mind:
- Table Limits: Ensure that doubling down is within the table’s betting limits.
- Card Counting: If you are a card counter, your decision might vary based on the count. For example, if the count is high (indicating more high cards remaining in the deck), doubling down becomes even more advantageous.
In summary, doubling down on 11 against a dealer’s 10 is a strong play in blackjack. It adheres to basic strategy and offers a positive expected value. While individual hands can vary, following this strategy will give you the best chance of winning in the long run.
Key Takeaways:
- Always double down on 11 against a dealer’s 10.
- Understand the probabilities and expected value.
- Consider table limits and card counting if applicable.
By adhering to this strategy, you can enhance your blackjack gameplay and increase your chances of success.

Frequently Questions
What are the key rules to understand in blackjack?
In blackjack, the primary goal is to beat the dealer by having a hand value closer to 21 without exceeding it. Face cards are worth 10, aces can be 1 or 11, and other cards are their face value. Always hit if your hand is below 17, but stand if it's 17 or higher. Splitting pairs can double your bet, but only do so with 8s or aces. Doubling down allows you to double your bet for one more card, typically when your hand totals 9, 10, or 11. Remember, the dealer must hit on 16 and stand on 17. These rules help you strategize and improve your odds in blackjack.
How do you play basic blackjack?
In basic blackjack, aim to reach 21 without exceeding it. Start with two cards, face up for players and one up, one down for the dealer. Cards 2-10 are face value; face cards are 10; and Aces are 1 or 11. Hit to draw more cards; stand to keep your total. Dealer must hit until 17. If you go over 21, you bust and lose. Beat the dealer's hand without busting to win. Blackjack, an Ace plus a 10-value card, pays 3:2. Split pairs and double down for strategic plays. Basic strategy and card counting can enhance your odds.
How do you apply basic strategy in 2-deck blackjack?
In 2-deck blackjack, basic strategy involves making mathematically optimal decisions to minimize the house edge. Start by understanding your hand's value and the dealer's upcard. Always hit on hard totals under 12, stand on 17 or higher, and double down on 10 or 11 if the dealer has 9 or less. For soft hands, hit on totals under 17, stand on 18 or more, and double on 13-17 against a dealer's 5 or 6. Split pairs of 8s and Aces, but avoid splitting 10s and 5s. By adhering to these guidelines, you enhance your odds of winning.
How do you play 8-deck blackjack using basic strategy?
Playing 8-deck blackjack using basic strategy involves making mathematically optimal decisions based on your hand and the dealer's up card. Start by understanding the basic strategy chart, which guides you to hit, stand, double down, or split based on specific hand combinations. Always split Aces and 8s, and never split 5s or 10s. Double down on 10 or 11 if the dealer has a 9 or lower. Stand on hard 17 or higher and soft 18 or higher. Hit on hard 8 or lower and hard 12 to 16 if the dealer shows 7 or higher. Follow these rules consistently to minimize the house edge and improve your chances of winning.
How do you double down in blackjack?
In blackjack, doubling down is a strategic move where you double your initial bet after seeing your first two cards. To do this, place an additional bet equal to your original wager next to it. You then receive one more card, after which you must stand. This option is typically advantageous when your hand totals 9, 10, or 11, as it increases your potential payout. However, it also doubles your risk, so consider the dealer's up card and your odds before deciding. Always follow the specific rules of the table, as some may limit doubling down to certain hand values or after splitting pairs.
