# How to Beat the Odds at Blackjack

Blackjack is a game where math and statistics can help you beat the dealer. While some players believe that blackjack is a game of chance, computer analysis reveals that for every combination of the player’s hand and the dealer’s upcard there is a single play (hit, stand, split, etc) that results in the highest probability of winning. However, mastering these techniques takes years of practice and is not for the faint of heart.

The most important thing to remember when playing blackjack is that the dealer must hit until his or her cards total 17 or higher. This is an incredibly important rule to remember, because if the dealer has a blackjack, you will lose your bet. If you have a blackjack, on the other hand, you will win 3:2 on your bet.

Before you play blackjack, make sure you know what your bankroll is. This will allow you to decide how long you want to play and how much of your money you want to spend. You should also take into account the buy-in and bet limits for the table you are playing at. This will help you avoid going over your budget and prevent you from losing your money.

One of the most common mistakes that blackjack players make is to ignore the odds of the game. This is because they think that luck is the only way to win, but in reality, the odds of the game can give them better or worse chances of winning. Fortunately, there are many online resources that can help you understand the odds and probabilities of blackjack.

In a standard game of blackjack, the dealer will draw a card on average every four hands, meaning that there is a 28.1% chance that he or she will bust. On the other hand, the player has a much lower chance of busting, so it is always wise to hit when you are dealt a two-card 21, unless the dealer has a face card or an Ace.

If you have a two-card 21 and the dealer has an Ace, you should always take insurance. This is because the expected value of insurance is positive, while the dealer’s blackjack is a negative expectation bet. In addition, the dealer’s insurance bet is a sucker bet for players because it pays 2:1 while the dealers blackjack odds are very close to 9:4 (2.25:1), depending on the number of decks being used in the game.

Lastly, players should only hit when their cards add up to 11. This is because it is impossible for the dealer to bust at this point, and you will be paid out at 3:2 if you have a blackjack. However, if your cards add up to 10, you should consider standing instead. This is because it is likely that the dealer will have a weaker hand, and standing is a safer option for you in this case.
