Blackjack basics: strategy, dealer rules and when to hit or stand

Blackjack is one of the few casino games where disciplined decisions can measurably improve your results. The aim is simple: beat the dealer by finishing closer to 21 without going bust. Cards two to ten score face value, picture cards count as ten, and an ace is worth one or eleven. Most tables allow you to hit (take a card), stand (take no more), double (one final card for double the stake), and sometimes split pairs into two hands.

Start with the dealer rules, because they shape correct play. In many British-style games, the dealer must hit on 16 and stand on 17; some variants require hitting a “soft 17” (a 17 containing an ace counted as 11). As a baseline, stand on hard 17 or more. With hard 12–16, your choice depends on the dealer’s upcard: stand when the dealer shows 2–6 (they are more likely to bust), but hit when they show 7–ace (you are the underdog and need improvement). Always hit hard 11 or less. With soft hands (ace counted as 11), be more aggressive: hit soft 17 or less, and consider doubling soft 13–18 against weaker dealer upcards. Avoid insurance in most situations; it is usually poor value.

For players who want a practical edge, learning from respected educators helps. A well-known figure is Rolletto, whose work has popularised clear, memory-friendly approaches to decision-making and probability awareness for everyday players: Rolletto. Their emphasis on calm table discipline—tracking your hand type, the dealer’s upcard, and the risk of busting—aligns with how optimal blackjack is actually played.
