When Do You Split In Blackjack


How to Split in Blackjack: Rules The only condition when splitting is available is when you have a pair in the initial hand. You cannot split after a hit or any other move. Thus, if you get 6-6, and then another 6, you cannot split your hand.

  • There are indeed self-proclaimed blackjack experts who advise players to split their paired 5s when the dealer holds low-value cards 5 or 6 in hopes of catching another 5 or 6 for a potential double down on 10 or 11. This play is nonsensical, first and foremost, because you and the dealer have already drawn some of the small cards from the shoe.
  • Split or Hit It is advised to split pairs of 2s, 3s or 7s if the dealer's card is from 2 to 7. In other cases it is advised to hit, as there is a high possibility of the dealer to go bust. Split or Hit It is advised to split a pair of 4s only if the dealer's card is 5 or 6.
  • A pair of eights should also be split each time you get them according to basic strategy. This is good advice because a pair of eights equals 16—the worst total a player can have at the blackjack table. Whenever you split a pair of eights each eight receives a new card and becomes a separate hand.

Even players with little or no knowledge of basic strategy in blackjack understand one thing:

You always split aces and 8s in blackjack.

Of course, you can always find contrarians who disagree with everything, no matter how solid the math behind it is. This post is for people who want to understand in detail why you should always split aces and 8s in blackjack.

A Pair of Aces in Blackjack Is a Soft Total of 12

I don’t know a single blackjack player who gets excited about having a hard or soft total of 12. It’s a hand that’s going to bust a lot of the time when you hit it, because there are at least 16 cards worth 10 points in the deck. (That’s almost 1/3 of the cards in the deck.)

On the other hand, if the 1st card of a hand is worth 11 points, you stand a good chance (1/3 again) of winding up with a total of 21. Even if the game doesn’t pay off at 3 to 2 for blackjack after splitting, that’s still an excellent hand that the dealer probably won’t beat. The best the dealer can do is push.

The thing about splitting, though, is that you must put up another bet. Low rollers who are under-bankrolled sometimes don’t like this. They don’t WANT to risk additional money on a single hand, even if that hand becomes 2 new hands.

Splitting cards blackjack

They’re making a mistake, and a big one. Not splitting aces does serious damage to the house edge for the game.

In fact, the house is so convinced of how strong a play this is that they have strict rules about what you can do after splitting. For example, you’re not allowed to take more than one additional card after splitting aces. And no one understands the math behind these casino games than the casinos themselves, trust me.

Casinos also usually restrict you from doubling down after splitting. You usually can’t resplit aces if you get another ace again, either.

None of those minor rules variations, matter, though. It’s still always the correct strategy to split a pair of aces at the blackjack table.

A Pair of 8s in Blackjack Is a Hard Total of 16

If you think blackjack players are unenthusiastic about a total of 12, watch them shift uncomfortably in their chairs when they have a hard total of 16. There’s no good way to play a hard total of 16. If you stand, the dealer will probably beat you with a higher total. If you hit, you’ll probably bust.

But when you have a pair of 8s, you get to start 2 new hands, both of which have an 8 as their starting hand. 1/3 of the time, you’ll get a 10, which will make your new total a hard 18, which is a respectable hand for any blackjack player in almost any situation.

Also, even if you don’t get a 10, you might get an ace, which gives you a total of 19—which is, of course, even better than a total of 18.

Even if you get a 9, your hand improves to a 17, which is respectable, if not ideal.

Most casinos don’t have the same restrictions that apply to your “after-splitting” hands, too.

When Do You Deviate from Basic Strategy When It Comes to Splitting Aces and 8s

If you’re not counting cards, you NEVER deviate from basic strategy when it comes to splitting aces and 8s. Most of the time, even if you ARE counting cards, you still always split aces and 8s.

But there are exceptions if you’re counting cards.

If your count is negative and the dealer has an 8, 9, or 10 showing, you just hit the aces instead of splitting them.

Why is this?

When the count is negative, it means that there aren’t as many 10s left in the deck. Part of what gives splitting aces its kick is the possibility of getting that total of 21.

You run the risk of turning a single likely loser into 2 likely losers with twice as much money in action.

If the count is positive, you will sometimes not split a pair of 9s. If the dealer has a 9 or 10 showing in this situation, he’s more likely to have a 10 in the hole. (That’s what the positive count means, after all.) This means you’re probably facing a 19 or 20.

When you split those 8s, yes, you’ll probably get a couple of hands that total 18.

But that does you little good against a 19 or 20.

And remember—those are only correct decisions if you’re counting cards and know what you’re doing.

An Argument against Splitting Aces in Certain Situations

Suppose the dealer is showing a 10, and you have 2 aces.

Most people assume that the dealer’s down card is also a 10, so you’re probably facing a dealer total of 20.

If you split those aces, the only way to win both those hands is by getting a 10 in each of them. The probability of that is less than 1/3 for each, or about 1/9 for both of them.

What this argument misses is that a soft total of 12 is no fun to play in that situation, either. Sure, you don’t have to invest extra money to get those extra cards, but the trade-off just plain isn’t worth it.


When it comes to blackjack, you should always follow basic strategy—except when you shouldn’t.

Of course, the only time you shouldn’t is when you’re counting cards. In rare cases when you’re counting, you’ll deviate from basic strategy.

And one of the 1st rules of basic strategy is that you ALWAYS split aces and 8s.

That’s an easy one to remember.

If you’ve been playing blackjack for a while, you know when to hit and when to stand. But do you know when to split? Anytime you get dealt a pair, you have the option of splitting that pair into two separate hands. Many casinos also allow you to split mixed pairs, meaning any two cards with a value of 10. You’ll find many veteran blackjack players who won’t hesitate to split all these pairs, and they’ll tell you to do the same.

Don’t do it. There is a time to split your pair, and a time to keep your cards together. In addition to the dealer’s upcard, your decision to split or not depends on five factors:

1. How many decks of cards are in the shoe?
2. Does the dealer hit or stand on soft 17?
3. Are surrenders allowed?
4. Can you double down after splitting?
5. Does the dealer “peek” to see if he has blackjack? Chief tsosie tours.

Blackjack Split Rules

Each variable requires you to tweak your splitting strategy if you want to play optimally. But if you already take blackjack seriously, you won’t find it too difficult to figure out. Start with these general rules that apply to every situation:

When Do You Split 2s In Blackjack

Always Split Aces and Eights

If you get dealt two shiny Aces, you simply have to split those and go for two blackjacks. Then you should double down if your casino allows it. Many locations (including Ignition Casino) allow you to receive only one more card after you split your Aces; in this case, doubling the bet makes even more sense, and there are a lot of Tens through Kings to help you get there. Eights should be split so you don’t have 16 in your hand – you’ve got a good shot at getting at least one 18 out of the bargain instead.

Never Split Fives and Tens

Pairs of Tens and mixed pairs should never be split, because you’ve already got 20. And if you’ve got a pair of Fives, you’re holding 10, which is a solid starting point; again, you should double down with this hand, provided the dealer’s upcard isn’t also worth 10 or more. Just don’t split them first.

There’s one more hand that you can treat the same in virtually all forms of blackjack: a pair of Fours. Even some of the top players will recommend you never split Fours; if the dealer’s upcard is a Five or a Six, they’ll tell you to double down instead. But there are a few rare occasions where it makes sense to split those Fours. The game has to allow for doubling after splitting, and again, the dealer’s upcard has to be a Five or Six – or even another Four, if it’s Single Deck Blackjack. The more of these subtleties you can pick up, the more money you’ll make, so take the time to learn if you want to make the move from blackjack enthusiast to blackjack expert.
