Blackjack is a game of chance in which the player attempts to accumulate cards that total 21 without going over. It is played with one or more standard 52-card decks, and the value of each card is its numerical value (the number, or a face value of 10, J, Q, K) or an ace. Players and the dealer get two cards each and make decisions to hit, stand, split, or double based on rules and payouts. The dealer’s expertise is key to the success of the casino and the player experience.

Blackjack has many myths surrounding it, but at a fundamental level the objective is simply to beat the dealer. To do so, you must have a hand value higher than the dealer’s.

This can be done by drawing a card that goes over 21, or by doubling down with a strong hand. The strongest hands are the ones that can be paired: A pair of fives (or two 10-value cards) or a pair of aces. Other strong hands include three or four of a kind and two pairs of matching cards.

The game of blackjack is often misunderstood by players, and this confusion can cost them money. A common mistake is betting on insurance. This side-bet pays 2-1 when the dealer has an ace showing, but it is a bad bet because it increases the house edge and makes it harder to win.

A blackjack dealer must have excellent interpersonal skills to be successful at their job. They must be able to interact with the players, explain the game rules, and answer any questions. They also need to understand the etiquette of blackjack and how to manage the table. A good blackjack dealer is a valuable asset to any casino.

Before starting their shift, blackjack dealers attend a meeting where they are informed about the specifics of their shift. This includes who is giving breaks, where they will be working, and any other important details.

After the meeting, the dealers go to their assigned tables and begin dealing cards. They will then explain the game rules to their customers. During the course of the game, the dealer will also be responsible for updating their shift log and taking any wagers from the players.

After the players have made their decisions, the dealer will check the hole card using a special viewing window in the table. If the dealer has a ten underneath, they will have a blackjack and pay out everyone’s original bets. If they don’t, the player will get their original bet back, and any insurance wagers will be paid out. This is known as a push. Typically, a blackjack push results in the dealer winning the round. However, it is possible for the players to have a blackjack as well and tie with the dealer’s hand. In this case, the player wins and receives their original bet back. It is also possible for the players to have a blackjack and not win the round, but this happens rarely.
