The rules of blackjack dictate that when a player is dealt two cards of the same value at the start of a round, they have the option to match their original bet and split the identical cards into two separate hands. Splitting pairs not only increases the entertainment value of the game but also works to the players’ advantage and decreases the house edge, i.e. when executed correctly.

The trouble is most novice players experience difficulties with pairs and often do not know how to play such hands optimally. Misplaying paired Aces is one of the most common mistakes among blackjack rookies which ultimately causes them to lose money in the long term instead of profiting. This article teaches you how to approach a pair of Aces optimally and explains when and why you should refrain from splitting them.

Casino Rules on Splitting Aces

Split aces blackjack

Splitting Aces is considered a very powerful move on behalf of players, so it is only natural for the house to try and do anything possible to prevent them from taking full advantage of this pair. In the majority of landbased and online blackjack variations, casinos prohibit players from hitting their Aces after a split. Instead, each Ace receives no more than one additional card, similarly to what happens after doubling down.

There are certain online variations of the game, like Microgaming’s Super Fun 21, where players get to enjoy more liberal rules when splitting this particular pair, like doubling down on each Ace and resplitting.

The ability to hit split Aces leads to a reduction of 0.19% in the casino’s advantage whereas that of resplitting them decreases the house edge by 0.08%. That being said, the software developers have compensated for the advantage these moves give the player by changing some of the other rules with more unfavorable ones. Worse of all, you get even money for your blackjacks which gives the casino a monstrous advantage over you.

Another peculiarity of Ace splitting results from the payouts you receive when you are dealt a ten-value card next to a split Ace. You have a two-card total of 21 but this is not treated as a natural in this case because it is not based on your original two-card holding. Instead, it is treated as a multiple-card 21 which returns even money instead of the higher 3-to-2 payout awarded for blackjacks.

An Ace is a good card to start a hand with, which is why most casinos do not allow their players to resplit pairs of Aces. This naturally makes doubling on split Aces impossible which also takes away some of your edge. Now that you have read about all these restrictions, you are probably wondering if splitting pairs of Aces is a good idea at all. It is. In fact, splitting Aces is always a good idea from the perspective of a basic strategy player.

Basic Strategy Players Should Always Split Aces

The optimal move for paired Aces is among the simplest ones to learn because it never changes in accordance with the playing conditions, the deck number, and the upcard of the dealer. You inevitably split the pair of Aces regardless of whether you are playing a single-deck H17 game or an eight-deck S17 game. No upcard of the dealer is powerful enough to intimidate you when you start a hand with an Ace.

A pair of Aces is actually a soft hand where the Aces have flexible values of 1 or 11. Thus, the total of the pair can be either 2 or 12 depending on which of the two values you choose. The thing about a 12, soft or hard, is it is not a good enough starting total. On the contrary, players end up busting in many cases with this hand.

Splitting Aces gives you the opportunity to create two brand new hands with a more advantageous starting point of 11. Players are always better off when the first card in their hand has a value of 11. This results in significant gains for them over the long haul which explains why most casinos would impose restrictions on how to play out this soft hand. Regardless of the casino rules for hitting, resplitting and doubling on split Aces, the mathematically correct decision for this hand is to always split.

The ten-value cards outnumber any other card denomination in the deck or shoe. There are four ten-value cards from each of the four suits in a single deck that can help you improve your total to the unbeatable 21 when you start with an Ace.

This corresponds to nearly one-third of the cards which means players stand a good chance of catching a 10 to each split Ace. Suppose you pull two Aces out of a 52-card deck along with a third card to represent that of the dealer, a 7, for example.

What are the odds of you catching a 10 as the next card on each Ace? There are now 49 cards left in the deck and 16 of them have a value of 10, which means the likelihood of you improving to 21 with your first Ace is 16 / 49 * 100 = 32.65%.

Basic Strategy Players Should Always Split Aces Additional TipsSuppose you indeed catch a Jack on the first Ace. This slightly reduces the likelihood of you pulling another ten-value card on the second Ace but you still stand a good enough chance. With 15 ten-value cards out of 48 cards left in the deck, the probability of you succeeding with a second score of 21 now stands at 15 / 48 * 100 = 31.25%.

A total of 21 is an excellent hand to obtain even if one does not receive a bonus payout of 3 to 2 after splitting like they normally would when they get a blackjack. In the worst-case scenario, you will end up pushing with your dealer and receiving your two bets back.

Even if you fail at catching ten-value cards, there are plenty of other cards that can help you improve to a total beyond the average winning hand of 18.5. There are four 9s you can draw for a total of 20 and four 8s for a total of 19.

Let’s assume you pick the discards from the previous round, put them back into the deck, and reshuffle. You again pull two Aces and split them against a 9. So what is the likelihood of improving each hand beyond the average winning total of 18.5?

There are 49 cards left and 23 of them can take you into the safe zone beyond 18.5 (four Queens, four Kings, four Jacks, four Tens, four 8s, and three 9s). The likelihood of you pulling one of them next to your first Ace stands at 23 / 49 * 100 = 46.93%! Assuming you get a 9 for a total of 20 on your first Ace, the probability of you drawing one of the “good” cards on your second Ace is now 22 / 48 * 100 = 45.83%.

The peculiarity of splitting, though, is that players are required to post another bet to cover the second hand that results after the pair split. Underbanked and casual gamblers are often reluctant to reach deeper into their pockets to cover their second hand and expose more money to risk, which naturally causes them to draw (or worse, stand) on their paired Aces.

The trouble is not splitting Aces improves only your chances of becoming a long-term loser in a game where the house has an edge against you even if you are a perfect basic strategy player. Just take a minute to ponder the following question – “If splitting Aces was a bad move for blackjack players, would the casino rules for split Aces be so rigid?”.

We think you are able to arrive at a conclusion on your own. The bottom line is despite the casino restrictions, splitting remains the best long-term decision when you hold a pair of Aces.

A Couple of Exceptions to the Above Rule

Some gambling authors argue Aces should not always be split and indeed, they are correct. There is one exception to the always-split-Aces rule and it is made for games like European Blackjack where there is no hole card. Here the dealer draws their second card after all patrons have played out their hands.

Certain basic strategy moves have undergone adjustments to accommodate the absence of hole cards. One of the adjustments concerns the pair of Aces against a dealer who starts their hand with an Ace, which, as you saw, is a very powerful card to start a hand with.

Instead of splitting, the strategy recommends hitting your soft 12 against an Ace and splitting against dealer upcards deuce through 10. The logic behind this adjustment is the following: the dealer cannot peek under their Ace for a blackjack after offering insurance – they get their second card only after you have completed your hand.

Additional Exceptions to the Above RuleSplitting becomes more volatile in this case because the dealer also stands a chance of drawing to a blackjack, in which case you lose two bets after splitting instead of one. Even if you have pulled a 10 next to each of your Aces, your “regular” total of 21 loses to the dealer’s blackjack. It is not worth the risk of pouring more money during this round.

Casino Blackjack Split Rules

There is a separate category of players who can justify deviating from the basic strategy play for paired Aces. These are the card counters most blackjack huffs have heard about. Some of you have probably even watched slightly exaggerated stories about them in Hollywood movies (who can forget the brilliant Dustin Hoffman as Tom Cruise’ autistic card-counting brother in Rain Man?).

The thing is counting enables these players to keep an accurate track of the cards. If there is a surplus of small cards, with fewer face cards left, a card counter would deviate from the basic strategy and refrain from splitting their Aces.

They would know there is a higher chance of them drawing a small card and getting stuck with bad totals on two hands instead of one. Until you get there, we suggest you take our advice and stick to basic strategy when you get a pair of Aces. Playing hunches inevitably results in depleting your bankroll in the long haul.

Nearly every gambling game has some combination that is statistically very unlikely, but still possible. That perfect outplay of cards, whatever it might be. It’s the kind of thing that you keep in the back of your mind because for the most part it is fun to do. You think to yourself as you flip over your hand each time, “Could this hand be the one?”

The blackjack split rules are interesting: if you keep getting dealt pairs, can you keep on splitting them until you run out of table space? This case study presents a couple interesting questions:

  1. What is the maximum number of times you can split in blackjack?
  2. Given the above, what is the best possible split blackjack hand?

Blackjack Rules Printable

The rules regarding splitting vary from casino to casino. Here is a general rundown.

Rules
  • Most casinos will allow two splits; some will not.
  • Some casinos will allow a double down after a split.
  • Most casinos will not allow any more cards after a double down.
  • Most casinos will only allow you one card after aces have been split.

Naturally, armed with the above information, you want to be playing at the types of casinos that allow you to do the following:

How To Split Blackjack

  • Split twice and then double down

The Best Possible Hand in Blackjack

It would go something like this:

  1. The dealer is showing a six or some bust card.
  2. You are dealt, say, fours – your bet is $10.
  3. You split these, and the fours both receive fours, which you spilt again – your bet is now $40.
  4. All these (4) hands with fours, all receive fours. You split again – your bet is now $80.
  5. You double down on eight hands – your bet is now $160.
  6. The dealer hits on 16, busts, and all your hands win.

Where your initial bet was for $20, you end up raking in $300. This example was purposely done without using aces to illustrate that it ultimately does not matter if you are splitting aces, because split aces do not payout 2:3 like a natural blackjack does. So even if we had split aces here, the payout would still be the same. In addition, since it’s already been stated that aces can only receive one more card after they are split, aces are in not going to give you the maximum amount of winnings possible in this scenario.

“But Atlantic City does it Differently.”

Interestingly, Atlantic City does not allow a split after the initial split, but it does allow a double down. This stands in direct opposition to Las Vegas, where as discussed the rules state that you can split again after the initial split.
