There are some best hands to split in blackjack. Looking at the table, consider that ace and 10 are the strongest cards or combinations, and 4, 5, and 6 are the weakest. This statement is based on complex mathematical calculations and should be accepted as an axiom. Let’s see the explanation for when to split in blackjack. The perfect time to split depends on the dealers up card. When you have ACES: ACES are rare in blackjack, but with so many pair of 10-value cards in the deck, it’s easier to get 21 when you have an ACE. Splitting ACES is one of the best cards you can play in blackjack. You should also re-split. In blackjack, the standard rule is that if the player is dealt a pair of identically ranked initial cards, known as a pair, the player is allowed to split them into separate hands and ask for a new second card for each while placing a full initial bet identical to the original wager with each.
Card counting is a system that experienced blackjack players use to get a profitable advantage over the casino. There are many individual “counts” or systems. Many of them are named after colorful professional gamblers from times past.
The 2008 movie “21” bought card counting to the attention of the general public. It followed the true story of members of the MIT blackjack team as they won millions from casinos in LasVegas. This movie also highlighted the key challenge faced by card counters. To make a profit using these systems, you need to bet significantly more when the odds turn in your favor. Casinos are aware of this — and will quickly ban players they believe are counting cards.
This page has everything you need to know to get started with card counting. Below you will find the basics of how it works. Famoussystems, the ideal games for counters and how online blackjack can help you learn to count are also covered below.
This Blackjack rule is fairly rare and should be avoided. Split any time - This allows you to Split a hand after drawing additional cards as long as you have two cards of the same value touching each other. For example, draw 10,2,2 and you can Split the Deuces. Split any 16 - Such as A5, 97, T6.
How to count cards in blackjack
Blackjack is a game of incomplete information. Players act based on their own two cards and the single dealer up-card. Players must risk busting in many situations, even though the decisions are mathematically correct.
Small cards are the enemy of blackjack players. Values of two through six can make for the trickiest decisions. In fact, if you remove any significant number of small cards from the shoe, blackjack not only becomes easier, the player gets a mathematical edge over the house.
This is where card counting comes in.
Counters track the proportion of small cards to face cards and aces. At a certain point, the deck turns “positive.” The higher proportion of face cards means every hand played will generate long term profit for the player — not the house. This is because profit comes from doubling, splitting and hitting blackjack (natural21). All of these are more frequent when there are more high cards in the shoe.
To take advantage of this edge, counting players must boost their bet size. Without this bet size boost, money spent playing while waiting for the deck to turn positive would cancel out any wins.
There are multiple factors that affect whether a specific game is a candidate for card counting. The number of decks of cards in play, the rules on splitting and doubling down, and how the dealer reacts to a soft 17 all come into play. To get the best from counting cards, you need to find the games with the lowest house edge.
Level 3 card counting systems & true count explained
Card counting systems have three levels of complexity. The simplest systems are Hi-LoCounts. You count low cards as +1 and high cards as -1. The higher the count, the bigger the proportion of high cards to low cards.
Advantage players will increase their bets once a specific count is reached. To be sure that they have an advantage, they need to translate the current total into the “true count” first. This involves dividing the count by the number of decks still in play. If the count is +10, with five decks remaining in a six-deck shoe, then the “true count” is 10/5 = 2. This means games like double-deck blackjack are better for counting. Players do not need to play through those first decks in the shoe while waiting for the true count to be positive.
Level two and level three counting systems are more accurate. They assign +2 to some cards and +1 to others. This splits the twos and sevens from cards three throughsix, with some systems also counting nines differently. There are systems with separate counts for aces. Your bet sizes need to increase in line with the positive count — for example adding a unit every time the true count increases by two points.
If you are new to cardcounting, then a simple Hi-Lo Count is the place to start. Once you have mastered keeping track of the count while playing each hand perfectly and chatting with the other players, you will be ready to move to the next level.
Examples of card counting systems
The systems below range from level one to three. These are five of hundreds of possible systems, giving you an overview of how different systems vary in their complexity.
- Hi-Lo Count: This is a balanced count and is the first system that new counters use. You add one to the total for each card value from two through six — and subtract one for 10s through aces. Seven, eight and nine are neutral. You then divide this count by the number of undealt decks and round up as needed. You should increase your bets when the count is positive — betting more the larger the positive number that you count. The advantage of the Hi-Lo system is simplicity. Compared with other blackjack counts, Hi Lo card counting does lackprecision.
- Hi-Opt1 and 2: These systems were developed by LanceHumble, though they can be traced back to the 1960s. There are many more“neutral”cards compared to the Hi-Lo Count. Hi-Opt 1 uses aces, twos, sevens, eights and nines as zero for the count. Three, four, five and six are +1, and 10s through kings are -1. This system works best for single deckgames. Hi-Opt 2 makes 10s through kings -2 on the count, with +2 for fours and fives, +1 for twos, threes, sixes and sevens. Aces, eights and nines are neutral. These are accurate systems, though with single deck games rare (and closely watched), it can be difficult to find a suitable game to use them.
- Ace-Five System: You will need to double your bet repeatedly as the count increases to make the Ace-Five System work. This is a simple count, involving only aces andfives. Every time a five is dealt, you add one, and every ace you see removes one. When the count is +2, you double your bet. Increasing it again for every +2 that gets added. If the count reverts to +1 or less, you go back to your initial bet size. The key advantage of this system is the simplicity. The always-changing bet size is likely to attract the attention of casino pit bosses.
- Uston Advanced Count: Ken Uston was a famous card counter, known for his flamboyant lifestyle. His most complex system is the “Uston Advanced Count.” Aces count as zero in this system. Fives are +3; 10s through kings are -3; nines are -1; twos and eights are +1; and threes, fours, sixes and sevens are +2. As with the other systems, you increase your bets in line with how positive the count gets — keeping the number of decks in mind. This system is designed to work best with a separate count of theaces. The complexity means that it is for experienced card counters only.
- KO Counting System: This system works like Hi-Lo, with an extra feature involving the insurance against dealer blackjack bet. It counts cards two through seven as +1, eight and nine as neutral and 10 through ace as -1. You should increase your bet at +2 or more (based on the true count). At +3 or greater, the insurance side bet becomes profitable and should be taken.
Which blackjack games are best for card counting?
Big casino resorts in Las Vegas, AtlanticCity, downtown Detroit and elsewhere run a wide selection of blackjack games. At the lowest buy-ins (typically $5 and up per hand), the rules give the casino a huge edge over theplayers. Examples include paying 6:5 instead of 3:2 for blackjack, limiting doubles after splits and having the dealer hit on soft 17. These unfavorable rules can easily boost the house edge to 3% or even more. With six or eight decks, getting a true count can be difficult.
Contrast this with the best games. An ideal setup is a single deck game, with liberal splitting/doubling rules, dealer standing on soft 17, late surrender and 3:2 for blackjack. With a house edge of 0.5% orless, these games are restricted to the high-limit rooms. This type of game is most likely to be closely monitored. Suddenly increasing your bet would be an instant trigger for experienced casino staff to watch closely.
Successful counters look for games with the lowest natural houseedge. They know the basic blackjack card counting strategy perfectly, so as not to give any edge back to the casino in the form of mistakes. If you do not know how to adapt blackjack strategy to subtle differences in the rules, then you are not yet ready to learn card counting techniques.
Is counting cards illegal in the US?
Counting cards is legal, unless you are using a mechanical or electronic device to help you keep track of the cards. Casinos do not want card counters in their games. People who are suspected of counting will be asked to leave the casino. Repeat offenses can see players banned — with trespass laws coming into effect if they attempt to return.
In 1979, Ken Uston took a casino in Atlantic City to court, challenging its right to ban “skilled” players. The court found in his favor. Rather than banning players, AC casinos now implement measures to stop card counting from working. They include regularshuffling, limiting players to flat bet sizes on each shoe and not allowing players to join a game mid-shoe.
Elsewhere, casinos will quickly ban players caught counting. This was the reason that the MIT team played in pairs. One player (betting small) would keep count, then signal to the big bet player when the count was positive. This player could then join the table, betting big amounts, while the original counter continued with smaller bets.
Card counting in other casino games
Very few casino games use a shoe containing several decks of cards. Casino poker variations like Caribbean stud or Ultimate Texas Hold ’em have a continual shuffle system, where a fresh shuffled deck is used for each hand. Baccarat does use a shoe, though it is not suitable for counting due to the complex scoring rules. Edge sorting is used in baccarat, though it is considered illegal in many jurisdictions.
This leaves blackjack variations like Spanish 21 and Free Bet Blackjack as the only candidates for card counting systems. Many variations of blackjack have a higher house edge than the main game. Spanish 21 removes 10s from the deck — starting the count on a negative.
Experienced advantage players use card counting to beat optional side bets. This requires a separate understanding of how each side bet works, with a counting system developed separately. Separate aces counts in blackjack can determine when the insurance against dealer blackjack bet becomes profitable.
Is it possible to count cards online?
Online casinos in regulated states have both live dealer and software-based blackjack options. They also have a range of games with different rules and side bets. Add in the game variations based on the 21 concept — and you will find a wide array of choices.
Advantage play through card counting is not possible at online casinos. Software based games use random number generator software to shuffle the cards for every hand. This means no count is possible. Live dealer games that are dealt in real time use eight deck shoes. What they do differently from brick and mortar casinos is reshuffle after around half of the cards are dealt. This makes it hard to spot situations where there is a positive true count. Add to this software that will instantly detect the bet sizing changes associated with counting.
What you can effectively do online is practice your counting skills. There are live dealer rooms at many of the biggest online casino brands, including Golden Nugget and BetMGM. You can enjoy a game and learn to keep score of the count while you play. Starting with simple systems like Ace-Five and Hi-Lo is ideal — you can move on to the more advanced systems as you gain experience.
If you live in a state with legal online casinos, make sure you keep a close eye on the casino bonus and promotion offers. You never know when a bonus aimed at blackjack players will become available.
Wrapping up: Card counting in blackjack
Card counting has been a part of blackjack since the1960s. Famous players including Humble and Uston published books on beating the house. Many of them are now considered among the classics of gambling literature.
Counting cards in blackjack gives you an edge over the house when there are relatively more high cards in the deck. This takes advantage of the player’s option to split, double down and to take insurance against dealer blackjack. Counting systems are graded into three levels, depending on their complexity. More complex systems are more accurate — though harder to use.
There is an Achilles’ heel for card counters. To make your knowledge of the count profitable, you need to significantly boost your bet sizes when the odds are in your favor. These bet size increases are a flag to casino staff to watch your play closely — which leads to card counters being banned. Card counting is not illegal, unless you use a device to help you keep track.
Online casinos are the perfect place to practice your card counting skills. You will not be able to get an advantage from them — as safeguards are in place. Live dealer casinos show a real table, making this the ideal way to find the right card counting system for you ahead of your next visit to a brick and mortar casino.
Splitting in Blackjack is one more solution available for Blackjack players. It can be used in combination with the double down or surrender option – the main thing for the players to consider is how to combine these solutions to get a better result. In this article, we are going to disclose the situations when this move has to and shouldn’t be used. Along with that, we will disclose a proper approach to this solution.
What Does a Split in Blackjack Mean?
A split solution means that you play two hands instead of one after getting the initial hand. Each hand is played solely, which means that you can lose with one hand and win with the second. This solution can be a good choice, if the cards in your initial hand, can bring you more chances to win, if distributed into two hands, instead of being used in just one.
Some players ignore this move, leaving no chance to double their winnings or decrease their chances of losing. The thing is that this solution can only be used for your benefit if you are familiar with card counting and know the essence of this move.
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. However, there are some casinos that impose restrictions on splitting:
- Splitting is allowed only once.
- After splitting, you cannot get a natural Blackjack even if you have 10-Ace; it is valued as an ordinary 21.
- Some pairs cannot be split (Ace, 10, etc.).
- No double down after splitting allowed.
Generally, you can split as many times as you want. For example, if you get a pair of 6’s, you can split. Then you get two hands with one 6 in each one.
If in one of the hands, you get another 6, you can split that hand as well. Thus, you will get 3 hands with 6 cards. Though, some of the casinos only allow you to split once.
You also can split Aces, as well, in some of the casinos. That means that once you have an Ace-Ace, you can split and get two hands with one Ace card in each of them. Make it clear in the casino, whether you can split Aces, as some of the houses forbid that.
Double down is a move that allows you to increase your bet per hand and limits the number of cards you can get afterwards. After splitting, you can make a double down for one hand and use any other move for another hand. The outcomes for each hand won’t affect the outcome of the other hand. Though, some of the casinos do not allow you to double down after splitting.
Thus, along with knowing how to use the decision to split correctly, you also should find out the rules of eligibility for this move, in the specified casino. These rules can have a great effect on the results of the game.
Why Do You Need to Split Cards in Blackjack?
Many players do not really know when splitting is a good decision. In this article, we have disclosed situations when splitting can improve your results, and here we will answer the question, why do you need to split your cards at all.
There are three main reasons to use this move:
- Splitting can maximize your profits
- It can minimize your losses
- It can improve your initial hand
How can splitting maximize your profits? If the dealer has a weak hand, splitting your hand means you play two hands instead of the dealer’s weak hand. This means that you have more chances to win, so you use this move as much as possible, depending on the situation, when the dealer gets a weak hand in a specified game.
How can splitting minimize your losses? If the dealer has a strong hand or a moderate hand, depending on your hand and the Blackjack game rules you play, you can surrender (if possible), split, or hit.
For some of the card combinations (which are pointed out in this article), the best decision would be to split. You get the chance to have at least one strong hand against the dealer’s hand. Thus, you can minimize your losses.
How can splitting improve your hand? If you have 2 cards that can make a good combination in separate hands but make a bad combination in one hand, it may be better for you to make a splitting decision than to hit, double down or surrender. Thus, choosing this option gives you the chance of a stronger combination.
Splitting Strategy: When You Should Always Split Cards in Blackjack
Unlike the other solutions, for a split, there are situations when splitting is always a good option, no matter what the card combination is in the dealer’s hand. This is true for a pair of Aces and a pair of eights.
The main reason for the pair of aces to get split is that an Ace in the initial hand is always a good card. When you get 10 with an Ace, it is a natural Blackjack, and moreover, an Ace can be valued both like 1 or 11. Consider the fact that for your initial hand with two Aces, you get a sum of 12, and the only way to get a Blackjack comes when you get 9. Whereas, when you split, you get far more winning combinations.
When it comes to the eights, there is another reason for splitting – a hard 16 is a weak hand. It is not enough to stand, as the majority of dealers stand or hit with a soft 17. It is risky to hit with this combination, as any value that is higher than a 5 will bust your hand. You get much better options if you split, and get an eight in two hands.
You should also resplit in case you get Aces or eights in hand after the first split. The reasons for the resplit are the same as for the first split. The only reason you couldn’t use split for Aces or resplit for Aces and eights, is the situation when this move is restricted by the casino. Below you can see some examples of hands with eights and Aces that would be valuable to consider for your gaming strategy.
Split Aces
Your hand: Ace-Ace
Dealer’s up card: Any
No matter what up card the dealer has, you should split. Even if the dealer has an Ace as well, which increases the chances of him having a natural Blackjack or another strong combination.
When you split, you get two potentially strong hands, instead of one that has a value of 12. After you split, you have more options to double down or hit until you get the best value.
Split Eights
Your hand: 8-8
Dealer’s up card: Any
Hard 16 is a weak combination, as you have a 60% chance to go bust with it. Moreover, the majority of dealers stop on soft 17, so even standing on hard 16 isn’t the best option. Normally, if you get a hard 16, it is better to consider the surrender option. However, if you get pairs with an opportunity to split, you should use it, as there many chances to get a strong combination with an eight in your hand.
What cards not to split?
There are cards that you shouldn’t split under any circumstances:
- A pair of fives
- Pair of fours
- Pair of tens
The thing is that splitting these cards, no matter what card is in the dealer’s hand, will decrease your chances of winning dramatically. Below we will provide you with a detailed disclosure on each combination.
Don’t Split Tens
A pair of tens gives you 20. This is one of the best combinations to stand when playing Blackjack, as you are likely to win. Splitting will be a very risky move.
The thing is that the majority of dealers stop at soft 17, which means that you need to get 7 or more after the split to win. Based on this calculation, you have more chances to win the round if you stand on 20. Example
Your hand: 10-10
Dealer’s up card: 8
With the dealer’s eight or any other card in the game, a casino has a very low chance of winning, as it should collect 21. On the other hand, your 20 is a great value to stand at.
Never Split Fives
Splitting fives is a bad idea, as you have a better option of doubling down depending on the dealer’s up card. Most players choose the split option in this situation, basing their decision on the fact that 5 in hand gives you a great number of options for the second card and future moves. However, it is proven mathematically, that you get more chances to win if you double down or hit in this position.
Your hand: 5-5
Dealer’s up card: 4
If you split now, you have to take the risk of getting a weak combination against the dealer’s 4 with another card in hand. If doubling down, you will have more chances to acquire a stronger value than the dealer.
Never Split Fours
Having fours gives a higher chance to get more than a soft 17 than if you split this hand. Here you get even more chances to get a weak hand than with fives. You will ultimately get weak initial hands instead of a stronger one. Based on the mathematical calculations, hitting is better than splitting here.
Your hand: 4-4
Dealer’s up card: 9
In this situation, you will have fewer chances to get a strong initial hand, as if the second card in the dealer’s hand is of high value, you will have to hit numerous times, for both hands with totally unpredictable results. More chances to win remain if you hit with 4-4 giving you an 8 and a higher chance to beat a soft 17.
Splitting Other Cards in Blackjack
Along with the combinations that leave only one option on whether or not to split, there are also other combinations that can leave you with options depending on the dealer’s up card.
When to Split Twos, Threes, or Sevens
Twos, threes, and sevens should be split if the dealer shows a card with a value of 7 or less. The reason is that twos and threes give you 4 and 6, which is a naturally weak initial hand to move on, and if you split this pair, you will get far more chances to get a strong combination to hit. You should also split sevens, as you have more chances to get a strong combination by hitting two cards afterwards, than with a hard 14.
Your hand: 2-2
Dealer’s up card: 4
As you can see in this situation, you have a value of four, while the dealer has 4 as an upcard only. It is less, so you can easily split your cards, and then hit as many times as you need to. With such a combination split, you have more chances to get a high value, than with a four against four and the second card in the dealer’s hand.
When to Split Sixes
Split a pair of sixes when the dealer shows 2, 3, 4, 5, 6. Based on the mathematical calculations, your hard 12 can give you a better result, when the dealer has 7 or more, and your six in hand can result in a stronger combination when the dealer has less than 7.
Hit Or Split Blackjack
Your hand:6-6
Dealer’s up card: 8
Here, you have a hard 12 against the dealer’s 8. You only can go bust if you get a 10, while you do not yet know the dealer’s situation. Any other card added will only improve the value of your hand, thus hitting is a better option than splitting, when you get two weak six combinations, against the dealer’s 8.
Splitting Nines
Splitting nines is a good idea against the dealer’s 2-6, 8, and 9. When you split against 2-6, 8, you get a better combination without the risk of getting busted on the next hit. With the 9 up card, you have the same chances on the new hand. Seven is excluded from here as mathematically, the dealer has greater chances of getting a strong combination.
Your hand: 9-9
Dealer: 5
If you split now, you will get two hands with nines in each, against the dealer’s 5 card. This gives you better chances to win twice. Standing here would be a good option as well, and still, you can increase your profits if you split.

Other Blackjack Strategies
Along with splitting, you can also make other moves that can be combined with splitting or used solely depending on the game rules and situation. Knowing how to use these moves can improve your results dramatically, otherwise, they can be useless. Thus, there is double down, hit & stand, and surrender.
Double Down
Double downis a move that considers increasing your initial hand. It is only available for the initial hand, and after using this move, you can only get one card in hand. Sometimes double down is available after splitting, sometimes not – it depends on the rules. Double down can increase your winnings and is valuable for those who use long-run strategies.
Hit & Stand
Hit is a basic solution available for all blackjack games. It means that you take an additional card to improve your hand. This move is available only until you get a value of 21 or get busted. The stand solution is about no longer taking any more cards. It is used when you believe the combination you have is the best you can get in that hand. Hit & Standshould be used in combination with other moves.
Surrender
Surrenderis an option that is not presented in the majority of Blackjack games. Thus, when it is available, you can use it to decrease your loses. The surrender solution can only be used upon receiving the initial hand and means that you stop the hand, and receive 50% of your original wager.
