Blackjack Strategy: When to Split and Stand

One of the most exciting parts of blackjack is that we sometimes have the opportunity to make a raise on our initial bets. When we have the chance to double down or split, it is important that we do the right thing. We will make the usual multiplier bets based on the results.

Sometimes in the case of splitting and doubling after splitting, we may find that our average bet on a round is four to five times the average bet, so it is important to know what you should do.

What is a blackjack split?

When you have two identical cards, such as a pair of 4s or 8s, you can split the pair and play them as if they were two separate hands. When splitting, you can only split the same amount as the original bet, which is different from a double bet, where you can reduce your bet. Only players can split their cards, the dealer cannot. You must have two cards of the same value. You must split the same amount as the original bet.

If you do not want to understand the entire basic blackjack strategy, the easiest way to play is to

  • Always split the aces and eights.
  • Never split the 10s.
  • If you are allowed to double on a split, split only 4s.

Basic strategy for blackjack splitting

  • 10s

The interesting fact is that in blackjack, all 10-value cards are splittable. This means you don’t have to wait to receive one Jack and another Jack. theoretically, you could split your Kings and Queens, or your 10s and Jacks. You shouldn’t, but you can. 20 is a good hand. Yes, a few more 20s could be great, and if the dealer has 5 or 6 up, maybe you’d like to get more money on the board. But the math is clear. Stick to the bird in your hand and don’t go looking for the one in the bush.

  • Pair of Aces or 8s

These two pairs are often heard together because no matter what happens with the dealer, we always split the aces or eights. it is important to note that usually only one card is allowed per ace, and a ten card dealt to a split ace is 21, not a blackjack. All other pairs can be split into a maximum of four hands.

  • Pair of 6s or 4s

If you have any pair, you will want to split if the dealer has 2 to 6 as the top card. Otherwise hit.

These rules should apply to more than 90% of the games you encounter. Most other rules don’t change strategy much.

What to do if you encounter a no-double after splitting the rules

Some casinos have adjusted their rules so that you can’t double up after a split. While this increases the house advantage by 14%, it can cost them money. If you encounter this rule, it’s best to just find another casino. But if it is the only one in your area, then you will need to make some changes to the pair split.


Although not a universal rule, it can still be found in some places. For the sake of completeness, we will cover a slight deviation from the basic strategy when offering surrender. No matter how many decks there are, and only in games where the dealer hits a soft 17, you should give up your pair of 8s against the dealer’s aces.


This should cover all possible blackjack rules you may encounter. Remember: pair splitting with this basic strategy is essential because it can help you get more money, usually more money, on a board with odds in your favor. So it’s best to stick with it as long as possible. When you should use these hands, make sure to double up to really enhance your advantage.
