For 4 to 8 decks with blackjack paying 3:2 and a dealer who checks for blackjack. Every cell was checked against an exact EV calculation for its two-card hand. Single- and double-deck games move a few cells (9 against a 2 becomes a double, for one), and the app adjusts for them.

How to use it

Find your hand down the side and the dealer’s card across the top. The cell is the play that loses least or wins most over the long run.

  1. Classify the hand

    Is it a pair, a soft total with an ace counting as 11, or a hard total? Check pairs first, then soft, then hard.

  2. Read the dealer’s card

    Against 2 through 6 the dealer busts often, so the chart stands and doubles more. Against 7 through ace, it hits more.

  3. Take the special play first

    Surrender, split and double are only offered on your first two cards. If the cell says double and you can’t, follow the fallback in the key.

Which rules change the chart

Only a handful of cells move with the rules. They are all close calls, which is why a single rule is enough to tip them.

Dealer stands on soft 17

Three cells soften: hard 11 against an ace becomes a hit, and soft 18 against a 2 and soft 19 against a 6 become stands.

No double after split

Splitting small pairs is worth less when you can’t double the new hands, so 2,2 and 3,3 against a 2 or 3, 4,4 against a 5 or 6, and 6,6 against a 2 become hits.

Late surrender

Give up half the bet on hard 16 against a 9, 10 or ace, and hard 15 against a 10. When the dealer hits soft 17, also surrender hard 15 and hard 17 against an ace, and 8,8 against an ace.
