Strategy can reduce the casino's mathematical edge, but it cannot guarantee a win. Rules vary by table; confirm the posted rules and gamble only with money you can afford to lose.

Frequently asked questions

What is a blackjack strategy chart?

A blackjack strategy chart maps your hand and the dealer's upcard to the mathematically preferred hit, stand, double, split, or surrender decision.

Does basic strategy guarantee a win?

No. Basic strategy reduces avoidable decisions and can lower the house edge, but every hand remains subject to chance.

What do H17 and S17 mean?

H17 means the dealer hits a soft 17. S17 means the dealer stands on a soft 17; this rule is generally better for the player.

When should I split aces and eights?

Standard multi-deck basic strategy splits aces and eights against every dealer upcard, although casino-specific restrictions still apply.

What does double after split mean?

Double after split, or DAS, lets you double the wager on a newly split hand after receiving its next card. It changes several pair decisions.
