Blackjack: The Double
Blackjack is a casino card game where players compete against the dealer rather than each other. The goal is simple: achieve a hand value as close to 21 as possible without exceeding it.
What is Doubling in Blackjack?
Doubling (or “Double Down”) is a Blackjack action where you double your original bet in exchange for receiving only one more card. This move is a high-risk, high-reward strategy that should only be used in situations where you have a strong advantage.
How and When to Use Double Down
- Doubling down is best used when you have a strong starting hand and the dealer has a weak upcard.
- Typically, you should double when:
- You have a total of 9, 10, or 11.
- The dealer shows a low or weak card (2-6).
- You can afford the extra bet.
Blackjack Doubling Strategy Table
Below is a basic strategy table for doubling, based on your total hand value and the dealer’s upcard.
| Your Hand | Dealer’s Upcard | Double Down? |
|---|---|---|
| 9 | 3, 4, 5, 6 | ✅ Yes |
| 10 | 2, 3, 4, 5, 6, 7, 8, 9 | ✅ Yes |
| 11 | 2, 3, 4, 5, 6, 7, 8, 9, 10, A | ✅ Yes |
| Soft 16 (A,5) | 4, 5, 6 | ✅ Yes |
| Soft 17 (A,6) | 3, 4, 5, 6 | ✅ Yes |
| Soft 18 (A,7) | 2, 3, 4, 5, 6 | ✅ Yes |
Explanation of the Table
- Hard Totals (9, 10, 11):
- 9: Double when the dealer shows 3, 4, 5, or 6.
- 10: Double against anything except a 10 or Ace.
- 11: Always double unless the dealer has an Ace (but in some cases, still a good move).
- Soft Totals (A+X Hands):
- A,5 and A,6 (Soft 16-17): Double against dealer’s 4, 5, or 6.
- A,7 (Soft 18): Double against dealer’s 2, 3, 4, 5, or 6.
When NOT to Double
- If the dealer is showing a 7, 8, 9, 10, or Ace.
- If your total is 12 or higher.
- If you cannot afford the extra bet.
Final Tips
- Always check the rules of the table (some casinos don’t allow doubling after splitting).
- Doubling is one of the strongest moves in Blackjack when used correctly, so use it strategically!
