Blackjack is a game of chance and strategy. It is played using one or more 52-card decks and the goal is to get a hand that totals as close to 21 as possible without going over. There are many different variations of blackjack, but all have the same basic rules. Players get two cards and can choose to hit (receive more cards) or stand (stop receiving cards). The dealer also gets two cards and must either hit or stand based on predetermined rules.
During the course of a game, players may double their wager on any two cards after they receive them, or on any pair of cards. This is known as Doubling Down. This is a risky move because the player’s total point value could go over 21, but it can also produce a very high return if successful. Typically, only the highest cards count in a double down, and only tens, Jacks, Queens, and Kings are considered to be worth 10 points.
Some casinos allow players to take insurance against the dealer’s potential hand of blackjack. This side bet pays 2 to 1 if the dealer has blackjack, and it is generally made by placing chips in the “insurance bar” above the player’s cards. Players must pay their original bet if they have taken insurance, but this helps to reduce the house edge slightly.
The game of blackjack is a fast-paced, exciting game that can be very lucrative if the player understands the basic strategy and is willing to put in the effort. While some books and websites claim to teach players how to beat the game of blackjack, these methods are often misguided or even outright rubbish. Fortunately, the mathematics behind blackjack are fairly simple and can be used to tilt the odds in the player’s favor.
There are a few fundamental things to remember when playing blackjack: Firstly, the game is played with a standard 52-card deck. The cards have thirteen values: Aces can be worth either one or eleven; the numbers 2 through 10 each represent a different value; and the face cards of Jacks, Queens and Kings each count for ten points. The game is also characterized by the fact that you can only split pairs of cards of the same value once, and that you cannot re-split aces.
As a rule, you should always hit when your hand value is 11 or lower, and stand when it is 16 or higher. However, the dealer’s up card can make it more advantageous to hit – for example, if you have 17 and the dealer is showing an 8, hitting makes it less likely that you will bust (because the dealer is more likely to draw a 10 than you are). Therefore, you should stick with your hands if the dealer is showing an 8 or higher.
