The Basics of Blackjack

Blackjack is one of the most popular casino games. It is played with a standard 52-card deck, with the cards 2 through 10 worth their face value and the aces counting as either 1 or 11. The object of the game is to draw a hand closer to 21 than the dealer’s without going over. The player may also choose to buy insurance or surrender. If the dealer has a blackjack, the players lose their bets. The game was invented in the United States, and is thought to be a descendant of a Spanish card game called 21.

The game is generally played in a casino setting, though it can be played outside of a casino as well. The game is usually staffed by casino employees, and the dealers are specially trained to deal with the players in an appropriate manner. In some cases, a blackjack table will be reserved for high rollers, who pay more per hand than other players.

When a player sits down at the blackjack table, he or she usually places a bet in the betting box, then the dealer will shuffle and cut the cards. In some games, the dealer will hold the cards in his or her hand; however, in most casinos today the dealer deals the cards from a shoe (a boxlike device that holds the cards). The cards are placed in front of each player and are dealt face up.

In a two-card hand of blackjack, an ace and any ten-value card are called a ‘natural’ or ‘blackjack’ and automatically win the player 3:2 on the bet. This is a big advantage over other casino games, such as craps and roulette, where the house has an inbuilt statistical edge.

It is possible to reduce the casino’s edge to a small percentage through careful play, known as basic strategy. This determines when to hit and stand, as well as when to double down or split a hand. There are dozens of websites that outline the correct basic strategy, though slight variations will occur depending on the number of cards used and the rules of the game.

The rules of the game vary by casino, but most allow a player to buy insurance against the dealer’s blackjack and to surrender his or her hand before the dealer checks for a blackjack. Buying insurance reduces the house edge to about one half of one percent of the original bet.

Some players use a strategy called card counting to improve their odds of winning. This involves keeping track of the concentration of aces and tens in the deck, and increasing or decreasing bets accordingly. A detailed explanation of card counting is beyond the scope of this article, but wikiHow has an extensive card counting page for more information. A less sophisticated method, involving the addition and subtraction of cards, is also available. This method is not as accurate, but can still improve the player’s odds of winning by making bets more aggressive when the deck is favorable to the player and vice versa.
