The quick rule
In blackjack, you hit when the risk of busting is still worth the chance to improve your hand. You stand when your current total is strong enough, or when the dealer is more likely to bust. That sounds simple, but the dealer's upcard changes everything.
A dealer showing 2 through 6 is usually in a weaker position because the dealer must keep drawing on low totals. A dealer showing 7 through Ace is stronger because they can more easily finish with 17, 18, 19, 20, or blackjack.
Hard hands: no Ace counted as 11
A hard hand can bust immediately if you draw a high card. For example, hard 16 means any 6, 7, 8, 9, 10, Jack, Queen, or King can push you over 21. That is why hard totals require the most discipline.
| Your hand | Common basic strategy idea |
|---|---|
| Hard 8 or less | Hit. You cannot bust with one card, so improve the hand. |
| Hard 12-16 | Stand against many weak dealer upcards, hit against strong dealer upcards. |
| Hard 17 or more | Stand. The bust risk is too high to draw another card. |
Soft hands: Ace gives you flexibility
A soft hand includes an Ace counted as 11, such as Ace-6 for soft 17. The hand is safer because if you draw a high card, the Ace can count as 1 instead. That flexibility means soft hands often play more aggressively than hard hands.
Soft 13 through soft 17 often draw or double depending on the dealer upcard. Soft 18 is a common trap: it feels strong, but against a dealer 9, 10, or Ace it is often not enough, so basic strategy may tell you to hit.
Common confusing hands
Do you hit on 13?
Hard 13 is usually a stand against dealer 2 through 6, because the dealer has bust risk. Against dealer 7 or higher, hard 13 usually hits because your current total is too weak.
Do you hit on 16?
Hard 16 is one of the worst hands. Against dealer 2 through 6 you often stand. Against dealer 7 through Ace you usually hit unless surrender is available and correct for that rule set.
Do you hit on 21?
No. A total of 21 is already the best possible total. Stand and let the dealer finish the hand.
How to practice this decision
Start by memorizing three groups: hard totals, soft totals, and pairs. Then practice with a basic strategy chart beside you until the decisions feel automatic. Do not use short-term outcomes to judge a decision. You can make the correct hit and still lose; strategy is about the long run.
