What Is Blackjack Split and When to Do It?

Whether you play European blackjack or any other single or double deck variant of this popular game, it’s essential to learn all about blackjack split and its rules. Knowing when to split cards can help players decrease the house edge and increase their own odds of getting the best possible hand.

When you play blackjack for real cash, splitting cards will effectively allow you to play with two individual hands. Having two hands means you’ll also have to double the size of your original bet, but it will also double the payout if you manage to defeat the dealer.

In this article, we’ll discuss the best card splitting strategy you can use to improve your chances of winning in a game of blackjack.

What Is Blackjack Split?

The option to split is offered to players when their initial two-card hand comes with two cards of the same value.

If they choose to split, they will split their hand into two separate ones and then receive an extra card for each of them.

As we already mentioned, splitting will require placing an additional stake on the new hand. The bet must be equal to the one made at the beginning of the game.

When to Split?

There are specific hands in blackjack, which require players to split. It’s the probability that dictates it’s favourable to do. On the other hand, there are hands when it’s advisable not to split, while in some instances, the dealer’s up-card determines whether players should split or not.

Although splitting improves your odds of winning, it doesn’t guarantee you’ll win. But if you follow the blackjack split rules, you are more likely to emerge victorious in the long run.

Always Split

Players should always split a pair of aces. There are plenty of cards with a value of ten in the deck, so making this move makes perfect sense. If you choose not to split, one of your aces will have a value of eleven, while the other will be given a value of one. Such a situation means that only a nine can result in twenty-one. Drawing a card whose value is ten will count both your aces as one.

We should point out that having two eights is regarded as a relatively poor hand in blackjack, regardless of whether you split them or not. However, if you don’t split them, you won’t have much room for maneuver, as any card with a value of six or more will bust you. Splitting a pair of eights can help you get a more competitive hand.

When the Dealer’s Up-Card Determines the Split

If you have a pair of twos, threes or sevens, you should split them only if the dealer’s up-card is two, three, four, five, six or seven. Making such a move is likely to improve the competitiveness of your hand.

A pair of nines may sound good, but beating eighteen can easily be beaten. So if the dealer’s up-card is two, three, four, five, or six, you should split without hesitation.

If the dealer’s up-card is two, three, four, five, or six, and you have a pair of sixes, splitting the hand will significantly improve your chances of winning. Getting a ten after the split could give you an advantage over the dealer.
