Learn what split means in blackjack. Discover when to split pairs like Aces and 8s, and understand the basic strategy to lower the house edge.
What Does Split Mean in Blackjack?
Splitting is a fundamental blackjack rule that allows you to turn one hand into two separate hands. You can use this option when your initial two cards are a pair, such as two Eights or two Aces. The move requires you to place an additional bet equal to your original wager.
By splitting, you create two independent hands that are played out one after the other against the dealer's single hand. This strategic decision can turn a weak starting hand into a winning opportunity. Knowing when to split is a key component of basic blackjack strategy.
When You Are Allowed to Split
You can only split if your first two cards are of the same rank. Most casinos allow you to split any pair, while some have restrictions on which pairs can be split, often limiting splits on ten-value cards. The option is usually presented after the initial deal and before you take any other action.
After you split, you will receive one additional card on each of your new hands. You then play each hand sequentially, with the standard options to hit, stand, or double down available. Some casinos also allow 're-splitting' if you receive another card of the same rank after the initial split.
Basic Strategy for Splitting Pairs
Not all pairs should be split. Basic strategy provides clear guidelines based on the dealer's upcard. For example, you should always split Aces and Eights. Splitting Aces gives you two chances to hit a natural blackjack, while splitting Eights turns a hard 16, a very poor hand, into two starting hands of 8.
Conversely, you should never split pairs of Tens, Fours, or Fives. A pair of Tens is a strong 20, which you should stand on. A pair of Fives totals 10, which is an excellent opportunity to double down. Following these rules minimizes the house edge over the long term.
- Always split: Aces and 8s
- Never split: 10s, 5s, and 4s
- Split 2s, 3s, and 7s against a dealer 2-7
- Split 6s against a dealer 2-6
- Split 9s against dealer 2-6, 8, 9 (but not against a 7 or 10/Ace)
Frequently Asked Questions
Can you split after hitting in blackjack?
No, you cannot. The option to split is only available on your initial two-card hand. Once you choose to hit and receive another card, you forfeit the right to split that original pair. The decision must be made immediately after the deal.
What happens if you get a blackjack after splitting Aces?
If you are dealt a ten-value card on a split Ace, it is usually counted as 21, not a natural blackjack. This means it typically pays even money (1:1) instead of the 3:2 payout for a natural blackjack. Always check the specific table rules, as this can vary.
Can you double down after splitting?
This depends on the casino's rules. Many games allow 'Double After Split' (DAS), which lets you double down on the new hands created by splitting. If DAS is allowed, it is a favorable rule for the player. Some tables do not offer this option, which increases the house edge.
