BLACKJACK BASICS

Blackjack Moves Explained

Learn what each blackjack move means and when it can be used. Your recommended action depends on your hand, the dealer’s upcard and the table rules.

Hit

Take another card to increase the value of your hand. The calculator will tell you when hitting is the recommended blackjack strategy.

Stand

Keep your current hand and take no additional cards. Standing is recommended when taking another card would reduce your expected outcome.

2×

Double Down

Double your original bet and receive one final card. Whether doubling is available depends on the table rules and your current hand.

║

Split

Split a pair into two separate hands when the cards have the same value. Each new hand is then played individually.

↩

Surrender

Give up your hand before completing it and lose only part of your original bet. Surrender is only available at tables that offer the option.

Insurance

Insurance is a separate wager offered when the dealer shows an Ace. It is not part of the standard blackjack hand and is generally excluded from basic strategy.

BLACKJACK BASIC STRATEGY

Blackjack Strategy by Hand

Blackjack strategy changes depending on your hand and the dealer’s upcard. Use our blackjack calculator to check the best move for hard hands, soft hands and pairs.

Hard Hands

No usable Ace

A hard hand is a hand where the Ace is either absent or must be counted as 1 to avoid going over 21. The correct blackjack strategy depends heavily on the dealer’s upcard.

Hard 8–9 Consider hitting or doubling depending on the dealer.

Hard 10–11 Doubling can be a strong option when the rules allow it.

Hard 12–16 The dealer’s upcard becomes especially important.

Soft Hands

Ace counted as 11

A soft hand contains an Ace that can currently be counted as 11 without making the hand exceed 21. Soft hands can provide more flexibility when deciding whether to hit or double.

Soft 13–15 Strategy depends on the dealer’s upcard and table rules.

Soft 16–17 Hitting or doubling may be appropriate in specific situations.

Soft 18 One of the most important soft hands in basic strategy.

2×

Pairs

Two cards of equal value

When your first two cards form a pair, you may have the option to split them into two separate hands. Whether splitting is correct depends on the pair, dealer upcard and table rules.

Pairs of 2s–6s Splitting decisions vary significantly by dealer upcard.

Pairs of 7s–10s Some pairs are commonly kept together rather than split.

Aces Splitting rules can have a major effect on the decision.

EXAMPLES

Common Blackjack Strategy Situations

The correct blackjack move can change dramatically depending on the dealer’s upcard. A blackjack calculator can help you check the recommended action for a specific situation.

11 vs 6

Hard 11 vs 6

A common situation where doubling down may be considered when the table rules allow it.

16 vs 10

Hard 16 vs 10

A difficult decision where the dealer’s strong upcard makes the correct strategy particularly important.

A7 vs 9

Soft 18 vs 9

A soft hand where the recommended action depends on the dealer’s card and the rules selected.

8,8 vs 10

Pair of 8s vs 10

Pair situations can require a completely different decision from ordinary hard or soft hands.

FAQ

Blackjack Calculator FAQ

Find answers to common questions about blackjack basic strategy, table rules and how to get the most from our blackjack calculator.

What is a blackjack calculator?

A blackjack calculator is a tool that helps determine the recommended action for a specific blackjack hand. It uses your cards, the dealer’s upcard and the selected table rules to compare the available moves.

What is blackjack basic strategy?

Blackjack basic strategy is a mathematically calculated approach to choosing the best action for a particular player hand and dealer upcard. It determines when to hit, stand, double, split or surrender according to the rules of the game.

Is blackjack strategy always the same?

No. The recommended strategy can change depending on the number of decks, blackjack payout, whether the dealer hits or stands on soft 17, and other table rules. This is why selecting the correct rules in the blackjack calculator is important.

Should I hit or stand on 16?

There is no single answer for every 16. The correct action depends on the dealer’s upcard and the rules of the table. Enter your exact hand and the dealer’s card into the blackjack calculator to see the recommended move for your situation.

Blackjack Hit or Stand?

Whether you should hit or stand in blackjack depends on your hand, the dealer’s upcard and the table rules. Enter your cards and the dealer’s upcard into our blackjack calculator to see the recommended move based on basic strategy.

Should I double down on 11?

Doubling on 11 is a common basic strategy situation, but the recommended action can depend on the dealer’s upcard and the rules governing doubling. Use the calculator with the correct table rules for a specific recommendation.

Does the number of decks affect blackjack strategy?

Yes. Blackjack strategy can vary between single-deck and multi-deck games. Select the number of decks being used at the table so the blackjack calculator can evaluate the hand using the appropriate rules.

Does the dealer hitting on soft 17 change strategy?

It can. A table where the dealer hits on soft 17 has different probabilities from one where the dealer stands on soft 17. Select the correct dealer soft 17 rule before calculating your hand.

Is a blackjack strategy chart better than a calculator?

A blackjack strategy chart is useful as a quick reference for basic strategy, while a blackjack calculator can evaluate a specific hand using the table rules you select. Both can be useful depending on whether you want a general reference or an answer for a particular hand.
