Frequently asked questions

Why does the recommended play depend on the dealer's upcard? Basic strategy weighs the dealer's chance of busting against your hand's potential, so the same hand can call for different actions — for example, standing on a stiff hand against a weak dealer upcard like 6, but hitting against a strong one like 9 or 10.

Does this strategy guarantee a win? No, basic strategy minimizes the house edge over the long run by making the statistically best play each hand, but blackjack still involves randomness, so any individual hand can still lose even with the correct play.
