A useful reply to "Do you win blackjack with 5 cards?" goes past the printed rules. Blackjack rules fit on a card, but the game at a real table carries habits that the card leaves out. Players meet the dealer one hand at a time, cards are dealt face up or down by house rule, and every decision, from standing to doubling, has a best answer. Knowing the rules for beginners and the etiquette around them is most of what separates a calm session from a confusing one.
Blackjack is partly strategy and partly luck. Luck decides the cards; strategy decides what happens with them, and basic strategy, a chart of the best play for every hand against every dealer card, cuts the house edge to around half a percent. That is the closest thing to a way to beat the dealer in blackjack: not winning more hands, but losing less on each. Players should double on eleven against most dealer cards, and on ten when the dealer shows less.
Whether blackjack is dealt face up depends on the house. Many shoe games deal the players' cards face up, while the dealer takes one card up and one down, or under British and European rules only one card until the players finish. Blackjack is never played with jokers; a standard deck or several decks shuffled together is used. Regional names such as Jamaican blackjack usually describe a set of house rules rather than a different game, so the rules printed at the table are what count.
