Do you hit on 15 against a 10
In the world of blackjack, one of the most common dilemmas faced by players is whether to hit or stand when they have a hand total of 15 against a dealer’s upcard of 10. This decision can significantly impact the outcome of the game, and understanding the optimal strategy can help players minimize their losses and maximize their wins.
Understanding the Situation
Before diving into the strategy, it’s essential to understand the context:
- Player’s Hand: 15 (e.g., 10 + 5, 9 + 6, etc.)
- Dealer’s Upcard: 10 (which could be a 10, Jack, Queen, or King)
In this scenario, the player must decide whether to take another card (hit) or stick with their current total (stand).
Basic Strategy in Blackjack
Blackjack is a game of probabilities, and basic strategy is a set of rules designed to minimize the house edge by making the most statistically advantageous decisions. Here’s how basic strategy dictates the action for a hand total of 15 against a dealer’s 10:
Basic Strategy Recommendation
- Hit: According to basic strategy, you should hit on 15 against a dealer’s 10.
Why Hit on 15 Against a 10?
- Dealer’s Potential: The dealer has a strong chance of making a strong hand. With a 10 upcard, the dealer has a high probability of having a 20 (10 + 10) or 19 (9 + 10) if they draw a face card or another 10.
- Player’s Hand Strength: A hand total of 15 is relatively weak. Standing on 15 means you are hoping the dealer busts, which is not a high-probability event.
- Probability of Busting: While hitting on 15 increases the risk of busting (going over 21), the potential reward of improving your hand outweighs the risk. The probability of drawing a card that won’t bust you (2-6) is higher than drawing a card that will (7-Ace).
Advanced Strategy Considerations
While basic strategy provides a solid foundation, some advanced players might consider additional factors:
1. Counting Cards
- High Card Count: If you are counting cards and the count is high, indicating more high-value cards remaining in the deck, the risk of busting by hitting on 15 increases. In such cases, some players might choose to stand.
- Low Card Count: Conversely, if the count is low, indicating more low-value cards remaining, hitting on 15 becomes a more favorable option.
2. Dealer’s Downcard
- Assumption: While you don’t know the dealer’s downcard, experienced players often make educated guesses based on the flow of the game and the cards that have been played.
3. Table Conditions
- Penetration: The depth of the shoe (how many decks are played before a shuffle) can influence your decision. A deeper penetration can provide more information and better predict the remaining cards.
In summary, according to basic blackjack strategy, you should hit on 15 against a dealer’s 10. This decision is based on the statistical likelihood of improving your hand versus the risk of busting. While advanced strategies like card counting and reading the table conditions can provide additional insights, sticking to basic strategy is the best way for most players to optimize their gameplay and reduce the house edge.
Remember, blackjack is a game of both skill and chance, and making informed decisions can significantly enhance your overall experience and potential winnings.

In this scenario, the player must decide whether to take another card (hit) or stick with their current total (stand).
Basic Strategy in Blackjack
Blackjack is a game of probabilities, and basic strategy is a mathematically proven method to reduce the house edge. Here are the key points to consider:
1. Dealer’s Upcard
- Dealer’s Upcard of 10: The dealer has a strong chance of making a total of 17 or higher, which is a favorable hand for the dealer.
2. Player’s Hand
- Player’s Hand of 15: This is a relatively weak hand, as it is below the dealer’s potential total of 17 or higher.
3. Probabilities
- Hitting on 15: There is a higher probability of busting (going over 21) if the player hits. However, standing on 15 against a 10 is also risky because the dealer is likely to improve their hand.
The Decision: Hit or Stand?
According to basic blackjack strategy, the optimal decision in this scenario is to hit. Here’s why:
Why Hit on 15 Against a 10?
- Dealer’s Strong Hand: The dealer has a high probability of making a strong hand (17 or higher). Standing on 15 means the player will likely lose unless the dealer busts.
- Busting Risk: While hitting increases the risk of busting, it also offers a chance to improve the hand. The potential gain from improving the hand outweighs the risk of busting in this situation.
Mathematical Perspective
- Expected Value (EV): The expected value of hitting on 15 against a 10 is higher than standing. This means that, on average, hitting will result in a better outcome over many hands.
Practical Tips
Here are some practical tips to help you make this decision in real-time:
- Stick to Basic Strategy: Memorize and follow basic strategy charts to ensure you make the best decisions.
- Practice: Use online simulators or free games to practice this scenario and others to build confidence.
- Stay Calm: Emotions can cloud judgment. Stay calm and focused on the game.
In blackjack, the decision to hit on 15 against a dealer’s upcard of 10 is a critical one. According to basic strategy, hitting is the optimal choice due to the dealer’s high probability of making a strong hand. While there is a risk of busting, the potential to improve the hand outweighs this risk. By adhering to basic strategy and practicing, players can make more informed decisions and improve their overall game.
blackjack 15 vs 5
Blackjack is a popular card game that requires both skill and strategy. One of the critical decisions players face is how to act when they have a hand total of 15 against a dealer’s upcard of 5. This scenario is particularly tricky because the decision can significantly impact the outcome of the game. In this article, we’ll explore the optimal strategy for this situation and provide insights into why it’s crucial to make the right choice.
Understanding the Situation
Player’s Hand: 15
- Possible Combinations: 10-5, 9-6, 8-7, 7-8, 6-9, 5-10
- Strength: A hand total of 15 is relatively weak, especially when compared to higher totals like 18 or 19.
Dealer’s Upcard: 5
- Dealer’s Potential: The dealer’s upcard of 5 suggests a potential hand total of 15 or higher. The dealer has a high probability of drawing a 10-value card next, which would give them a strong hand.
Optimal Strategy: Hit
The optimal strategy for a player with a hand total of 15 against a dealer’s upcard of 5 is to hit. Here’s why:
1. Probability of Improvement
- Player’s Hand: Drawing another card gives you a chance to improve your hand total. The probability of drawing a card that won’t bust your hand (i.e., a card with a value of 1-5) is relatively high.
- Dealer’s Hand: The dealer is likely to draw a strong card next, such as a 10, which would give them a hand total of 15 or higher. Hitting gives you a better chance to outscore the dealer.
2. Risk vs. Reward
- Risk: The risk of busting (going over 21) is present, but it is outweighed by the potential reward of improving your hand.
- Reward: If you hit and draw a card that improves your hand total to 16 or higher, you significantly increase your chances of winning the hand.
3. Dealer’s Potential
- Dealer’s Probability: The dealer has a high probability of drawing a strong card next, which could lead to a bust if they exceed 21. By hitting, you give yourself a chance to outscore the dealer before they draw their next card.
Common Mistakes to Avoid
1. Standing on 15
- Risk: Standing on 15 against a dealer’s 5 is generally a poor decision. The dealer is likely to improve their hand, and you will lose the opportunity to improve yours.
- Outcome: Standing on 15 often results in a loss, especially if the dealer draws a strong card next.
2. Doubling Down
- Risk: Doubling down on 15 is generally not recommended unless you have a specific reason to believe the dealer will bust.
- Outcome: Doubling down increases your bet but also increases the risk of busting. It’s usually better to hit and try to improve your hand without doubling your wager.
In blackjack, the decision to hit or stand with a hand total of 15 against a dealer’s upcard of 5 is crucial. The optimal strategy is to hit, as it offers the best chance to improve your hand and outscore the dealer. By understanding the probabilities and potential outcomes, you can make more informed decisions and improve your overall performance at the blackjack table.
Remember, blackjack is a game of both skill and strategy, and making the right decisions in key situations can significantly impact your success.
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.

For hard hands, stand on 17 or higher, double 10 or 11 against any dealer card except an Ace, and hit on 8 or less. Split pairs of Aces and 8s, but avoid splitting 5s and 10s. These adjustments optimize your strategy, enhancing your chances of winning.
