In blackjack, to 'split' means to separate a pair of identically valued cards into two independent hands. When your first two cards are a pair, such as two eights or two Aces, you have the option to split them by placing an additional bet equal to your original wager. This creates two separate hands that are played one after the other against the dealer's single hand.
Splitting is a powerful tool that can turn a weak hand into a winning opportunity or maximise a strong starting position. Knowing when to split is a critical component of basic blackjack strategy. This guide walks through the key scenarios and strategic reasoning behind this fundamental rule.
You can only split if your first two cards are of the same rank. After you place your split bet, the dealer separates the pair, and you now play two hands. You will be dealt one additional card to each of your new starting cards. You then play out each hand sequentially, with the standard options to hit, stand, or double down as the rules allow.
Basic strategy gives clear directives for certain pairs. You should always split a pair of Aces. Starting two hands with an Ace gives you a strong chance to build a blackjack or a high soft total. You should also always split a pair of eights. A hard total of sixteen is one of the worst hands in blackjack, while splitting gives you two chances to start anew with an eight.
Conversely, you should never split a pair of ten-value cards. A hand totaling twenty is extremely strong, and splitting it would risk breaking up a near-certain winner for two weaker hands. You should also avoid splitting a pair of fives. Two fives make a total of ten, which is an excellent doubling-down opportunity, not a candidate for splitting.
For several pairs, the correct decision to split depends on the value of the dealer's upcard. For example, you should split twos, threes, sixes, and sevens when the dealer shows a weak card (2 through 6), but not when they show a strong card (7 through Ace). You generally split nines unless the dealer shows a seven, ten-value card, or Ace.
Always check the specific table rules, as they can change the strategy. Key variations include whether you can 'resplit' if you draw another matching card to your new hand, and whether you can 'double after split' (DAS). Some games restrict you to drawing only one card on split Aces. Knowing these details is essential for optimal play.
Do you have to bet again when you split?
Yes, splitting requires you to place an additional bet for the new second hand. This bet must be equal to your original wager.
Can you split any two cards?
No, you can only split if your first two cards are a pair of the same rank (e.g., two Queens, two 7s). Some casinos may allow you to split non-identical ten-value cards (like a King and a Jack), but this is not standard.
What happens if you get a blackjack after splitting Aces?
If you draw a ten-value card to a split Ace, it is usually counted as a regular 21, not a natural blackjack. This means it typically pays at 1 to 1 (even money), not the premium 3 to 2 blackjack payout.
