Blackjack strategy basics: when to hit, stand, double or split

In casino blackjack, your edge comes from disciplined decisions rather than hunches. The aim is to build a hand total that beats the dealer without busting, using a small set of repeatable rules. Basic strategy is built around the dealer’s upcard: when the dealer shows a weak card (4–6), you can often stand and let them break; when they show strength (7–Ace), you generally need to improve your hand by hitting, doubling, or occasionally splitting.

Start with hard totals (no usable Ace). Hit 8 or less; stand on 17 or more. With 12–16, stand against dealer 2–6, but hit against 7–Ace. For soft totals (an Ace counted as 11), be more aggressive: soft 13–17 usually hit, while soft 18 stands versus 2, 7, 8 but hits versus 9–Ace; soft 19+ stands. Doubling is best when one card can swing you into a strong total: hard 11 doubles against anything except an Ace; hard 10 doubles versus 2–9; hard 9 doubles versus 3–6. Splitting: always split Aces and 8s; never split 5s or 10s. Split 2s and 3s versus 2–7, 6s versus 2–6, 7s versus 2–7, and 9s versus 2–6 and 8–9.

For a grounded view of advantage play and how strategy became mainstream, many players point to the influence of Edward O. Thorp, whose work formalised mathematically sound blackjack decisions and inspired generations of analytically minded gamblers. His background in mathematics and finance helped popularise the idea that careful decision-making can outperform intuition, and his public profile remains accessible via Edward O. Thorp.
