Blackjack is a game of luck, but it also requires some skill. The proper application of basic strategy can significantly improve your chances of winning, even if the dealer has an edge. In addition, learning to manage your bankroll effectively can help you avoid making emotional decisions that can lead to financial strain.

#### When to hit

It’s generally a good idea to hit when you have two cards that add up to 11 or less. It’s nearly impossible for you to bust at this point, and you’ll have a higher chance of getting a card that will bring your total up to 21. However, it’s important to note that hitting gives the dealer a 5% advantage over you.

#### When to surrender

If you have a weak hand and the dealer is showing a 4, it’s often best to surrender. The dealer has a high probability of busting, and you’ll lose the hand a significant percentage of the time if you stand. On the other hand, if you have a 10 and a 5, it’s likely that your total will be closer to 17 than 20, and you’ll have a better chance of winning by surrendering.

#### When to double down

Doubling down in blackjack is a strategy that can greatly improve your odds of winning by increasing the value of your initial hand. It involves doubling your original bet and receiving an additional card, which can increase the strength of your hand or give you a blackjack. Ideally, you should only use this strategy when the dealer has a weak card showing, such as a six or an ace.

#### When to split pairs

When splitting pairs in blackjack, it’s important to know which ones are worth playing and which ones should be stood on. For instance, a pair of tens should always be split, while a pair of fives should not. It’s also a good idea to only split if the dealer has a weak card, such as a seven or an ace.

#### Understanding blackjack math

It’s essential to understand the math behind blackjack in order to make smart betting decisions. You should practice counting cards by using a single deck and adding up the values of each card as you turn it over. This will create a running count that lets you know how many high cards are left. You can then produce the true count by dividing the running count by the number of cards remaining in the deck.

A lot of people have misconceptions about blackjack, and this can lead to bad gambling decisions. For example, some people think that buying insurance is a good bet, but it only works under certain circumstances and doesn’t shift the house edge much at all. In addition, it’s important to remember that you are playing against the dealer and not other players at the table. Keep this in mind and you’ll be able to make the most of your bankroll.
