The Basics of Blackjack

Blackjack is a casino table game that pits players against the dealer. Usually played on a semicircular table that can accommodate varying numbers of players, the game features a deck of cards that are shuffled before each round. A dealer stands behind the table with chips in hand, ready to deal cards. There are several different types of blackjack, with some games having an advantage for the house (which is represented by a negative percentage). However, by using certain strategies, players can minimize this advantage.

Each player is dealt two cards face up, while the dealer has one card face down. If the player’s first two cards total 21 or more, this is a “natural” and wins automatically unless the dealer also has a natural, which results in a tie. The dealer then sweeps the player’s bet and pays them one times their wager. If the dealer has a lower hand than the player, the player keeps their money and receives no payout.

When a player’s cards total 21 or more, they may choose to stand (refrain from taking another card and keep their current hand) or hit. If they hit, the dealer will give them one more card from the shoe. If they hit again, the dealer will take their original wager and pay them according to predetermined rules that determine their winnings.

If the dealer has an ace showing, they will usually offer insurance to players. This is a bad bet for the player, as it is impossible to know or estimate the value of the dealer’s hole card without having direct knowledge or experience in blackjack dealing (or through card counting). Insurance will pay 2:1, but the player has a better chance of winning by standing.

During the course of the game, the dealer will periodically glance at their own hole card. This allows them to see the value of their own card and adjust their betting accordingly. The tell player will watch the dealer to determine when they are looking at their hole card and bet based on what they anticipate it to be.

During the course of a blackjack game, the dealer will often change the rules of the table, such as allowing doubling after splitting, resplitting aces or surrendering. These rule changes can have a significant impact on the overall odds of the game.
