When should you hit or stand in blackjack?

Always stand on hard 17 or more. With hard 13–16, stand when the dealer shows 2–6 (they bust often) and hit against 7 through ace. Hard 12 is the exception: hit against a 2 or 3, stand against 4–6. Always hit hard 8 or less, and hit soft hands until at least soft 18.

When should you split pairs in blackjack?

Always split aces and eights. Never split tens or fives. Split 2s, 3s, and 7s against a dealer 2–7, split 6s against 2–6, and split 9s against 2–6 and 8–9 (stand against 7, 10, or ace).

When should you double down?

Double hard 11 against everything except an ace, hard 10 against 2–9, and hard 9 against 3–6. Soft hands double against a weak dealer: for example, double soft 17 (A-6) against 3–6, and soft 18 (A-7) against 3–6.

Does basic strategy guarantee you win at blackjack?

No. Basic strategy is the mathematically best decision for every hand, which shrinks the house edge to roughly half a percent — the lowest of any standard casino game — but the casino keeps a small long-run advantage. This trainer is for learning, not for gambling.

This table allows surrender

The complete basic strategy for the most common game: 4–8 decks, dealer stands on soft 17, double after split allowed. Find your hand on the left, the dealer’s up-card along the top — the cell is the mathematically best play. It doesn’t guarantee a win; it guarantees the smallest possible house edge.

Pairs

Su = surrender if the table allows it; otherwise hit. D = double if you’re allowed; otherwise hit. Ds = double if allowed; otherwise stand. Fives are missing from the pairs table on purpose — a pair of fives is just a ten. Never split it, double it.
