Blackjack is a game of card-counting and strategy, in which players try to beat the dealer by getting cards that total as close to 21 as possible without going over. The game is played on a semicircular table that can seat varying numbers of players (or “spots”). The dealer deals each player two cards face down and one to himself, and then allows the players to hit (request more cards) or stand (stop drawing) based on a set of rules.

In some casinos, the dealer will offer a side bet called insurance, which pays when the dealer shows an ace up. Some of these side bets are offered by all players, while others are offered only to the high-rollers at the table. The dealer will also collect the chips, shuffle them and start a new round of play.

Aside from being a fun and social game, blackjack can be a profitable endeavor. A knowledgeable player can reduce the house edge and increase his chances of winning by following certain strategies and rules. Some of these include learning the values of each card, counting cards, splitting 10s and staying on a 16 against the dealer’s 6.

The dealer is an important part of the blackjack game. He must be able to read the tells of the players and keep his emotions in check, which can affect the players’ decisions at the table. A good dealer is able to create a comfortable atmosphere for the players and build trust among them. He can also help players make informed decisions and avoid making bad ones by educating them on the rules of the game.

Dealers are also responsible for keeping the table in good shape and maintaining proper chip placement. They should be able to deal quickly and accurately. This ensures that all the players at the table are given a fair opportunity to win and reduces the risk of cheating by dealers or other players. They should also be able to maintain concentration and avoid distractions, which can cause a loss of focus and an unbalanced hand.

Some dealers are more skilled at reading tells than others, so it’s important for players to find a dealer who is right for them. Ideally, the dealer should be able to maintain eye contact with the players while still making sure they’re not giving away any clues about their betting or counting strategy.

Aside from knowing the basic rules of blackjack, it’s also a good idea for players to know how to bet wisely. If a player bets too much and loses money, he can get frustrated and leave the table. This can be disruptive to other players and is generally considered poor form.

Another tip is to avoid slamming down your bets too quickly. If you’re dealt a good hand and want to increase your bet, do it slowly and with caution. In addition, it’s best to stay within your bankroll. If you don’t, you may run out of money before you have a chance to make your next bet.
