Blackjack is fast, fun, and—with the right decisions—one of the casino games where players can meaningfully reduce the house edge.
The Goal of Blackjack
The objective is to beat the dealer by having a hand total closer to 21 without busting. Card values:
- Number cards = face value
- Face cards (J, Q, K) = 10
- Ace = 1 or 11 (player’s choice)
Why Basic Strategy Matters
Basic strategy is a set of mathematically optimal decisions (hit, stand, double, split, surrender) based on your hand and the dealer’s upcard. Following it reduces the house edge significantly.
Core Rules of Basic Strategy
Hit or Stand (Hard Totals)
- Always hit on 11 or less (you can’t bust).
- Stand on hard 17 or higher.
- On 12–16: hit if dealer shows 7–Ace; stand if dealer shows 2–6.
Soft Hands (hands with an Ace counted as 11)
- Soft 18 (A+7): stand vs dealer 2–8, hit or double vs 9–Ace depending on rules.
- Soft 17 and lower: usually hit; double when dealer shows weak upcards per chart.
Double Down
- Always double on 11 (unless specific house rules).
- Double 10 vs dealer 2–9.
- Double 9 vs dealer 3–6.
Splitting Pairs
- Always split Aces and 8s.
- Never split 5s or 10s.
- Split 2s/3s vs dealer 4–7; 6s vs 2–6; 7s vs 2–7; 9s vs 2–6 and 8–9.
Surrender (If Offered)
- Surrender hard 16 vs dealer 9, 10, or Ace.
- Surrender hard 15 vs dealer 10.

- Standing on soft totals when a hit/double is correct.
- Ignoring basic strategy because of “hunches.”
Final Tips
Bring a small printed strategy card if you need it—most casinos allow it. Play consistently: over many hands, basic strategy is what lowers the house edge the most.
