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. You've got to remember, however, to split your bankroll in half before you bet, otherwise, you won't be able to pair split. Unlike doubling down, you can't pair split for less. The bottom line for splitting 10s against a dealer 5 and 6 is this: Average players should never split and should always stand on 20. When you are allowed to Double Down After Split, you're going to split 2's and 3's when the house has the upcards of 2 through 7. You're going to split fours (4,4) when the house shows a 5 or 6, and 6's are split when the house shows 2 through 6. When DDAS is not available, you will absolutely be splitting less. Poor advice suggests a blackjack player should always split their hand when dealt a pair, no matter what. This is a fallacy, as the decision to split your hand relies mostly on what the dealer's up-card is. The decision to split pairs should be closely considered.
Blackjack has many wonderful qualities. It's a game where your decisions matter. It's also a game where you can get an edge over the casino (if you know how to count cards).
Most of all, it's just plain fun.
But blackjack is more fun when you're winning more often.
Luckily, it's a game where the mathematically correct way to play each hand has already been figured out. Computer programmers have run millions of hands of blackjack through simulators to come up with the moves that have the highest expected value.
A word about that:'Expected value' refers to how much a bet is worth. In some situations at the blackjack table, the expected value of a specific decision is positive. It might be more positive than other positive decisions.
In some other situations at the blackjack table, you must choose between the lesser of several evils. If you have a stiff hand, the best you can do is go with the decision that loses you the least amount of money in the long run.
As luck would have it, you only have a handful of totals to make decisions about. The highest possible total you can have without busting is 21. The lowest possible total with 2 cards is 4.
In the post below, I'll look at each possible total and how it could occur. Then I'll explain how to play that total based on which cards it's made of and what the dealer has as her face-up card.
All these explanations are based on basic strategy.
A Total of 21
When you have a total of 21, you should always stand. It doesn't matter what cards make up that total. It doesn't matter what the dealer's up-card is.
You always stand with 21. Any other choice costs money.
A Total of 20
You'll always stand with a total of 20, too, no matter what the cards are. It also doesn't matter what the dealer's face-up card is.
The reasoning behind this is clear. There's only one possible total the dealer could have which will beat a 20, which means you'll win with it most of the time.
You might need to decide whether to split a hard total of 20. If you have 2 cards of the same rank, you can put up another bet and start 2 hands using the cards in your hand as the first card of the 2 subsequent hands.
It seems like this might not be a bad idea. After all, any hand with a 10 as its first card is probably going to turn out okay.
It's a mistake, though. Https://poker.888sport.com/bet/. Most of the time, you'll wind up with 2 hands that aren't as strong as your total of 20. There are more cards in the deck that aren't worth 10 or 11 than there are cards which are worth 10 or 11.
A Total of 19
You will ALMOST always stand on a total of 19, regardless of which cards make up the total.
But there's one exception:
If you have a soft total of 19—an ace and an 8—you'll double down. But only if the dealer has a 6 showing.
In some casinos, you're not allowed to double down on a soft total of 19. If that's the case, you'll just stand.
On any other total of 19, though, you'll stand. It's such a strong hand that it will beat anything except a total of 20 or 21 from the dealer.
Goa Casinos Deltin Royale Casino, Deltin Jaqk, Casino Carnival, Casino Pride, Casino Pearl, Casino Palms, Casino Paradise, Chances Casino, Crown Casino and many other amazing casinos. Goa has always been the dream destination for all and if you are there a wild night is always a ‘yes'.
But even if you suspect that the dealer has one of those totals, your odds of winding up with a worse hand are too good for it to be a smart move to take another card.
The only reason you double down against a dealer's face-up 6 is because the dealer is so likely to bust that it's worth the risk.
A Total of 18
If you have a total of 18 that's made up of two 9s, you must decide whether to split your hand or not. Most of the time, you will split your hand, but there are exceptions.
You'll split a pair of 9s if the dealer has a 6 or less showing. You'll also split 9s if the dealer has an 8 or 9.
If the dealer has a 7, 10, or ace showing, you'll stand.
If you have a total of 18 that includes an ace that can be counted as 1 or 11, you have a 'soft' 18. If the dealer has a 6 or lower showing, and if the casino allows it, you'll double down on this hand.
If the casino doesn't allow you to double down on a soft 18, you'll stand instead.
If the dealer has a 7 or 8, you'll stand on a soft 18.
If the dealer has a 9, 10, or ace showing, you'll hit a soft 18.
Being able to count the ace as 1 or as 11 gives you some flexibility with how you play this hand. The combination of the possibility to improve your hand and the possibility that the dealer will bust results in the possible doubling down decisions.
Any other total of 18 will be a hard total, and you'll always stand on a hard total of 18.
A Total of 17
If you have an ace that counts as 1 or 11, you have a soft total of 17. In that case, you should double down if the dealer has a 3, 4, 5, or 6 showing. If the dealer has any other card showing, you should hit this total.
If you don't have an ace, or if counting the ace as an 11 would bust you, you have a hard total of 17. It's easy what to decide to do with a hard 17:
Always stand.
A Total of 16
Once you get down to the total of 16 or less, you're getting into 'stiff hand' territory. A stiff hand is one which is likely to bust.
It doesn't matter, though.
There's still only one correct way to play each stiff hand, too.
The first kind of total of 16 you should think about is a pair of 8s. You should always split a pair of 8s. The reasoning behind this should make sense. You're trading a mediocre hand for 2 hands which are likely to improve. More cards in the deck will improve an 8 than will hurt it. Any ace, 10, or 9 will give you a better total than 16. (And there are 16 cards worth 10 in the deck, so that's almost half the deck in total.)
The second kind of total of 16 to worry about is a soft 16. Again, this is a total where the ace can count as 1 or 11. You will NEVER stand on a soft 16.
You'll double down on a soft 16 if the dealer has a 4, 5, or 6 showing. If the dealer has any other card showing, you'll fold.
Finally, you need to know what to do with any other hard total of 16. You'll stand if the dealer has a 6 or less showing. You'll hit if the dealer has a 7 or higher showing.
If the dealer has a 6 or less showing, you're hoping she'll bust. Otherwise, you're hoping to improve your hand so that you have a fighting chance.

A Total of 15
A soft total of 15 is easy to play. You'll play it just like you would a soft total of 16, in fact. You'll double down if the dealer has a 4, 5, or 6 showing. Otherwise, you'll hit.
A hard total of 15 isn't hard to play, either, although it's a bummer of a hand. Again, you'll play a hard 15 just like you would a hard 16. Hit if the dealer has a 7 or higher. Otherwise stand.
A Total of 14
If you have a pair of 7s, you need to decide whether to split. You will split if the dealer has a 7 or lower showing. If you don't split, you'll treat the hand as any other hard 14.
If you have a soft 14, you will never stand. You'll double down if the dealer has a 5 or 6 showing. Otherwise, you'll hit.
If you have a hard 14, you'll play it just like a hard 15 or 16. Stand if the dealer has a 6 or less showing. Hit if the dealer has a 7 or higher showing.
A Total of 13
A soft total of 13 is played just like a soft 14. You'll double down if the dealer has a 5 or 6. Otherwise, you'll hit.
When Should You Split Cards In Blackjack
A hard total of 13 is played just like a hard 14, 15, or 16. Stand if the dealer has a 6 or less. Otherwise, hit.
A Total of 12
The first kind of 12 total to worry about is a pair of 6s. (You always consider whether to split first.) You should double down if the dealer has a 6 or lower showing. If not, you'll treat the hand just like you would any other hard total of 12.
Next, you'll think about a soft total of 12. This could mean you have a pair of aces. In that case, you always split. (Just remember—always split aces and 8s.)
There's no other way to get a soft total of 12, so you're left with the possibility of a hard 12. If that's what you have, you stand against a dealer 4, 5, or 6. Otherwise, you hit.
A Total of 11
If you have an ace and a 10, you COULD consider that a soft total of 11. But really, you have a blackjack. Just accept your winning with grace.
On any other total of 11, you'll double down. That's an easy decision, because you have lots of cards which will increase your total to 21. There's no real downside to doubling down on an 11, because it's impossible to bust such a hand.
A Total of 10
You never split 5s. They're always treated as a hard total of 10.
If you have a soft total of 10, you really have a soft total of 20, and I've already covered that. (Think about it.)
With a hard 10, which is really the only way you'll ever have a total of 10, you'll almost always double down. The only time you won't double down is if the dealer has an ace or 10 showing. In that case, you'll just stand. (You don't want to put extra money into play because of the increased likelihood that the dealer will have a 21.)
A Total of 9
A hard 9 is played ALMOST exactly like a hard 10. You should double down if the dealer has a 3, 4, 5, or 6. Otherwise, hit.
A Total of 8
You never split a pair of 4s. (In fact, you can remember this rule—never spit 4s, 5s, or 10s.)
In fact, there's only ONE way to correctly play a hard total of 8. Always hit.
A Total of 7
Always hit a hard total of 7.
A Total of 6
If you have a pair of 3s, split if the dealer has a 7 or lower showing. Otherwise, just hit.
If you have any other hard total of 6, just hit the hand.
A Total of 5
Always hit a hard total of 5.
A Total of 4
If you have a pair of deuces, play it just like a pair of 3s. Split if the dealer has a 7 or lower showing. Otherwise, just hit.
Conclusion
That's it.
You only have 18 possible starting totals in blackjack. Once you've learned how to play each of those totals correctly, you've mastered basic strategy.
Why is that a good thing to do?
If you've mastered basic strategy, the house edge for most blackjack games is between 0.5% and 1%, making it one of the best games in the casino.
If you misplay these hands, the house edge goes up. Most players are bad at basic strategy, by the way. If you look at the casino's numbers, the average blackjack player is so bad that he's facing a house edge of between 4% and 5%.
With those kinds of numbers, you might as well play craps or roulette. You don't have to make any playing decisions with those games.
memorize basic strategy in this way.
But even if you suspect that the dealer has one of those totals, your odds of winding up with a worse hand are too good for it to be a smart move to take another card.
The only reason you double down against a dealer's face-up 6 is because the dealer is so likely to bust that it's worth the risk.
A Total of 18
If you have a total of 18 that's made up of two 9s, you must decide whether to split your hand or not. Most of the time, you will split your hand, but there are exceptions.

If the dealer has a 7 or 8, you'll stand on a soft 18.

memorize basic strategy in this way.
When playing any Blackjack game you are going to get dealt out all manner of card combinations as your first two cards. When playing poker games an initial two card hand many players will be hoping are dealt out to them are a pair of Aces, and that hand combination can often be a very beneficial one for blackjack players too.
However, when playing virtually all online blackjack games whenever you are dealt out a pair of Ace cards then you are going to be given the option of being able to split those hands into two new separate hands.
When you decide to split any pair of Aces irrespective of whether they are matching ones of the same suits or not, you will then be obliged to place onto the blackjack table a new wager onto the new hand formed by one of your Ace cards.
You will be wondering when the correct time to split any pair of Aces is based on what card or cards the dealer may be showing, well you should always split them no matter what card the dealer is showing even if the dealer is also showing an Ace.
Be aware though that as you are going to have to place an additional stake on the new hand formed by one of your Aces then you will need to ensure that if you are playing for example the live dealer blackjack games online that you have enough cash reserves in your casino account balance to play that particular playing move.
For if you do not have enough funds in your casino account balance then when playing live dealer blackjack, as you are only allowed a certain short amount of time to make your playing decisions on each hand dealt out to you, there may not be enough time to visit the banking interface and load up additional funds into your account.
When that happens you are then not going to be able to split your hands as you will not have enough cash to make that move and as such you will only be able to hit or stand your hand which by the way in the incorrect playing strategy for playing any pair of Aces, and as such the house edge of the game you are playing will be increased when you hit or stand those Aces, which is something no blackjack player will want to happen.
So to ensure you are never caught out in such a situation always shave enough cash in your casino account to allow you to split a pair of Aces, more than once if required and also to double down any hands that may call for you double down on those hands.
Variants with Different Ace Splitting Rules
There are going to be some quite different rules attached to various different blackjack game variants you can access and pay online in regards to how you can play off any split Aces. With that in mind you should always be aware of those player rules before you start to play any blackjack game as it will have an effect on the house edge of that variant you are playing, in either a positive of negative way.
One playing rules found on a large number of blackjack games is that when you have chosen to split a pair of Aces after those cards have been split and have formed two new hands then the dealer is only ever going to deal one card to each of them.
However, some variants of blackjack will allow you to receive multiple cards to one or more split Aces and some variants are also going to allow you to keep on splitting Aces should any split Ace then have another Ace dealt out to those hands.
You will also find that you may be permitted to double down a split Ace depending on the value of the card that has been dealt out to it, and those particular variants will of course require you to have plenty of cash reserves in your casino account as you will have to pay to split the original set of Aces, and then to split any additional pair of Aces formed and also pay to double down on any hands which the perfect strategy for those games call for you to double down those hands.
Taking Insurance when the Dealer is showing an Ace Card
You will always find that when playing Blackjack online or in fact in a land based casino venue the dealer will from time to time deal himself or herself an Ace, and even if you are showing a pair of Aces then you are going to be offered the insurance wager.
Now when that wager is offered to you if you choose to accept it then on each hand that you opt to take the insurance wager on you will be required to pay a side bet wager of exactly half the amount of your base game hand. So for example if you are playing for 5.00 per hand and take insurance on one hand dealt out to you that side bet wager will cost you an additional 2.50.
Whilst the payout odds when the dealer has a blackjack hand is going to see you losing your original wager but being paid out at odds of 2 to 1 on the insurance side bet you may think that is a sensible side bet wager to place. However, nothing could be further than the truth.
The insurance wager is one on which the casino can make a lot of money over the long term for that bet has a huge house edge many times greater than the house edge of the variant you are playing, and as such the dealer will be looking for you to take the insurance wager as it increases the long term profit of that game. With that in mind you should never take insurance when offered to you as it is one of the worst bets you can ever place at a blackjack table.
