Blackjack strategy card
A blackjack strategy card is a printed reference that shows the mathematically best move for every possible player hand against each dealer up-card, based on the specific rules of the game being played.
- Also called
- basic strategy card, blackjack basic strategy card, strategy chart 34
- How it works
- Read the row for your hand and the column for the dealer's up-card, then follow the action: hit, stand, double, split, or surrender 3.
- Rule dependency
- The exact chart varies by deck count and rules such as whether the dealer hits or stands on soft 17 13.
- Key examples
- Stand on hard 12 against a dealer 4-6; double hard 9 vs. dealer 3-6; always split eights and aces 34.
Key points
- The card encodes optimal play for a specific rule set; using the wrong card (e.g., a single-deck chart for an eight-deck game) can increase the house edge 1.
- Actions are abbreviated: H for hit, S for stand, D for double, P for split, R for surrender 3.
- Basic strategy minimises the long-term house advantage, but no single house-edge percentage applies to all rule sets 12.
- Free PDFs of strategy cards are widely available online for common rule variations, including 4-deck, 6-deck, and 8-deck games 3.
