Understanding Basic Strategy

Blackjack basic strategy is a mathematically proven set of decisions that minimize the house edge and maximize your expected return over time. It tells you the optimal play for any possible hand against any possible dealer up card.

Key Concepts

Hard Hands: Hands without an Ace, or with an Ace counted as 1
Soft Hands: Hands with an Ace counted as 11
Pairs: Two cards of the same rank
Doubling Down: Doubling your bet and receiving exactly one more card
Splitting: Separating a pair into two hands, each with its own bet
Surrendering: Giving up half your bet and ending the hand immediately

Strategy Fundamentals

Always split Aces and 8s
Never split 10s or 5s
Always stand on hard 17 or higher
Always hit hard 8 or lower
Double down on 11 against dealer 2-10
Double down on 10 against dealer 2-9
Always hit soft 17 or lower (exceptions may apply based on rules)
Consider surrender with 16 vs dealer 9, 10, or Ace

Disclaimer: This calculator provides recommendations based on mathematically optimal basic strategy. Casino rules may vary, and card counting or other advanced strategies are not considered here. Basic strategy does not guarantee winning any particular hand, but it does minimize losses over time.

Basic Strategy Formula:

Optimal Decision = argmax(Expected Value(Hit, Stand, Double, Split, Surrender))
Where Expected Value is calculated based on probability outcomes derived from known rules and card distributions.

Frequently Asked Questions (FAQ)

Does this calculator guarantee a win?

No. It suggests the most statistically sound decision, but blackjack still involves chance. Over time, following basic strategy improves your results, but individual hands may still lose.

What does “Soft 17” mean?

A "Soft 17" is a hand where the total is 17 and includes an Ace counted as 11 (e.g., A,6). Whether the dealer hits or stands on soft 17 affects the strategy.

What if surrender isn’t available in my game?

If surrender isn’t an option, the calculator adjusts recommendations automatically—typically suggesting a hit instead.

Is this tool useful for beginners?

Absolutely. It simplifies decision-making and teaches basic strategy through repetition. Think of it as a poker probability tool but for blackjack—it guides your choices using proven outcomes.
