Blackjack Hit Or Stay Chart

Posted on by admin

If players’ priority is to win and to improve with every single blackjack game, then they need to put effort and time into achieving it. There are many other things that gamblers need to take into account and focus on prior to playing and during the game. To make the best possible decisions every time, players should prepare themselves beforehand.

For instance, it is recommended for them to have a look at every possible hand they can get and what their best choice will be in such cases. Knowing how to proceed in the difficult situations when players have a hand 14, 15, or 16 is crucial as the total value of any of the hands is significantly high which means that the chance of players busting increases.

Provided that late surrender is unavailable, you should stand on hard 15 against low-value cards 2 through 6 and hit versus 7 through ace. Undoubtedly, hitting a hard total of 15 is not the easiest decision to make at the blackjack table, especially against the dealer’s 10. Hit: Take another card. Afterwards you will have the option again to either hit or stand. If you go over 21 you will be bust and your hand will lose. Double: You will be offered this normally if you have 9, 10, 11, or any ace. If you click double your stake will now be doubled, so in the example above my bet will be £10. Fundamentally blackjack comes down to whether you 'hit' or 'stand'. Of course there have been big winners who have had that lucky night when they flew in the face of the odds and made some amazing hands. But these are the players who nine times out of 10 will walk away having. Blackjack Odds: Playing Hit or Stand will improve your blackjack strategy, and increase your chances of winning money. However, unless you count cards, the odds of blackjack are against you, even if you are a perfect player. By chance, the outcome may sway in your favor from time to time; but the rule is: the more you gamble the more money you. Blackjack Hitting and Standing hard totals - This basic strategy chart is identical for both single and multiple deck games. The decisions that you will make - hit or stand - are based on the dealers up card. In all my charts, the dealers up card is shown on the top row. The total of your two cards is shown in the very first column.

Whenever players’ hand total value is above 14, they are already in an unfavourable situation. Such cases require a good strategy and it is necessary for gamblers to think them through beforehand. Preparation and knowledge are compulsory if one wants to make the best possible decision.

Of course, as already mentioned, several other factors play a crucial role such as money management, discipline, decent bankroll and not to forget a bit of luck. Whenever players have the chance to turn the tables in their favour, they should take full advantage of the situation.

Important Things To Consider When Having Hand 14, 15 or 16

When players are unfortunate enough to get a hand 14, 15, or 16, they need to be very careful and stick to the strategy they have chosen. These are situations in which players are already one step from going bust regardless of the dealer’s upcard. However, this doesn’t mean that they should ignore its value, players need to always bear in mind that it is necessary for them to make their moves based on the dealer’s upcard.

Also, how players proceed in such situations shows their level of competence and knowledge to the rest of the players on the table. Since gamblers are already in an unfavourable situation, winning the hand shouldn’t be their priority. Instead, they should try to make the best move which is the move that will leave them with the smallest possible amount of money loss.

These are some of the trickiest hands in blackjack and as such, they are frequently misplayed. Part of the confusion results from the discrepancies in strategy charts. The optimal playing decisions vary depending on many different factors. These include how many decks are in play at the table, whether or not the dealer must hit soft seventeen, and whether players have the chance to late surrender.

All of these factors must be taken into account before you grab a basic strategy chart to take with you at the blackjack tables. What is optimal for hard totals 14 through 16 in a single-deck game may no longer be correct in multiple-deck variations.

What are Breaking Hands

The term breaking hands is commonly used in blackjack which places it among the important phrases players need to get familiar with. Gamblers have a breaking hand when they get their first two cards and they total 12 or above. The reason for this is that almost every single card will cause players to go bust (i.e. break their hand) as their total value will go over 21. Also, it can be referred to the dealer’s position as ‘breaking’ if their upcard is a 2 through 6.

The trouble with the so-called breaking hands 12 through hard 17 is that they invariably lose in the long term against all upcards of the dealer, including those that have higher bust rates for the house. Hard 14, 15, and 16 are particularly tough to approach because they lose more frequently than they win over the long haul.

The result is that the player ultimately ends up in the red with these totals no matter what playing decision they make. You probably think that’s bad. It is, but it gets worse since you will end up receiving horrible stiff underdogs approximately 40% of the time you spend at the blackjack tables.

What is a player to do with these hard totals then? The answer is simple – trust in basic strategy and approach such underdog hands courageously by making the correct playing decisions. And by ‘correct’ we do not necessarily mean the ones that would secure a winning outcome.

The moves basic strategy recommends for these three hard hands are considered optimal because they reduce your negative expectation, i.e. you will end up losing less money with these stiffs over the long haul. In other words, you are on the defence rather than adopting an offensive approach. In some cases, the strategy plays help you escape a highly disadvantageous situation and increase your winning chances.

Breaking Hands’ Situations

Blackjack Hit Or Stay Calculator

As the name hints, breaking hands is the situation when either the player or the dealer is in a very weak position. Such cases are extremely hard to cope with and the only way to have a chance of not going bust is to follow the basic strategy. Breaking hands are the reason why so many people lose in the long run as well. Thus, if players manage to learn how to deal with them, they will significantly improve their performance at the table.

The bottom line is that once gamblers have such breaking hands, the chances that they will go bust and lose are very high. However, if they use basic strategy, they will be able to improve their hand once in a while.

The move hitting here plays a crucial role and players should take their time to observe when they should hit and when this task should be left to the dealer. In cases where players have a breaking hand and the dealer’s position is standing, then they should hit. Otherwise, they risk losing the hand.

When Players Have Hand 14, 15 or 16

It will be best to have a look at all of these cases at once where players have a hand totalling 14, 15, and 16 as the strategy that needs to be used is the same. It is worth mentioning that the same goes for the situations when players have a hard 13 against different combinations of the dealer’s upcard.

Let’s first elaborate on the recommended strategy plays for hard 14. These are the easiest to remember since there are no discrepancies in the strategy based on decks and dealer rules. Hard 14 is always a stand when the dealer exposes small cards 2 through 6. The player must hit their hard 14 against all other upcards, namely 7 through ace.

When dealt A-3, you have a soft 14. This is a much better situation to be in since it is impossible to break this hand with a one-card draw. You have an advantage against a dealer who starts with weak small cards 4 through 6.

In single-deck S17 blackjack, you must double on soft 14 versus the dealer’s 4, 5, and 6. When playing with two to eight decks, you should double on A-3 only when the dealer has a 5 or a 6 provided that the S17 dealer rule applies.

A pair of 7-7 also adds up to a total of 14. In shoe games, this pair must be split when the dealer has 2 through 7 and hit versus upcards 8 through ace. At single-deck tables, the pair should be surrendered against the dealer’s 10. The rest of the moves coincide with those for multi-deck blackjack.

The player is also in a tough spot when holding a hard 15. This is a bad hand, to begin with, no matter what value the dealer’s upcard is. However, things get trickier since the best plays are influenced by the dealer’s drawing rules and the number of decks.

We shall tackle the strategy differences in more depth in the surrender section of the article. Provided that late surrender is unavailable, you should stand on hard 15 against low-value cards 2 through 6 and hit versus 7 through ace. Undoubtedly, hitting a hard total of 15 is not the easiest decision to make at the blackjack table, especially against the dealer’s 10.

Nevertheless, it has to be done because it results in the lowest possible negative EV for the player. The main idea behind hitting 15 against a 10 is that it gives you a shot at improving your situation. The differences might appear negligible but in the long run, they are not.

Soft 15 (A-4) requires a different approach due to the flexibility the ace gives you. You should double down versus low cards 4 through 6 and hit against all other cards the dealer starts with.

The situation of the player worsens even more when they are dealt a hard 16, the worst total one could possibly obtain in blackjack. There are several ways to get this terrible hand including 8-8, Q-6, 9-7, and 3-5-8. The pair of 8-8 should be split against all dealer upcards in the vast majority of blackjack variations. We expand on the particulars of this pair further on in this guide.

The correct strategy moves for hard 16, assuming you cannot surrender are relatively easy to remember. You stand on 16 against 2 through 6 and hit versus 7 through ace. The same applies to multi-card totals that add up to 16, or at least if you follow total-dependent basic strategy. In the absence of late surrender, hitting is again more optimal because it gives you the chance to improve your total against the strong dealer.

Players’ HandDealer’s Upcards

14SSSSSHHHHH
15SSSSSHHHHH
16SSSSSHHHHH

Again, all three hands will end up losing over the course of thousands of rounds played. The optimal decision is the one that cuts down your long-term losses the most. The above moves are recommended under total-dependent strategy. If you want to take your game to the next level, you can switch to composition-dependent strategy.

The latter takes into account the exact composition of the cards your hand consists of. Composition-dependent strategy recommends you to stand on hard 16 versus a 10 when your hand contains three or more cards like K-3-3. Also, when the 16 results from splitting a pair, you should stand rather than hit under composition-dependent strategy.

The Option to Surrender

There is one alternative move players can make which leads to the least money losses. However, due to this fact many landbased casinos do not offer the option to surrender as they know that if players know when to take advantage of it, they can greatly benefit from it.

Many professional gamblers won’t play in a casino which doesn’t provide the option to surrender when playing blackjack. However, if players find themselves in such a situation and there is no surrender option, all they can do is act according to the above-mentioned strategy and hope for the best.

When this option is available, most casinos tend to offer late surrender. This allows players to give up on poor hands like hard 15 and hard 16 in exchange for half of their original wager. With late surrender, you can forfeit a bad hand after the dealer has checked for blackjack when starting with an ace or a ten-value card.

Late surrender is beneficial to players because it takes away around 0.07% from the house advantage. Most novice players are averse to surrendering as the name of the move itself evokes negative connotations. However, surrendering is a smart move when you are dealt negative-expectation hands like 15 or 16 versus strong dealer upcards like 10s and aces.

As a general rule of thumb, surrendering is recommended whenever you receive a hand whose expectation of winning is less than 50%. The main advantage of surrendering is that it saves you money when you find yourself at a disadvantage. Late surrender is a defensive play which also allows advantage players to temper the effect variance has on their blackjack bankrolls.

The correct late surrender plays depend on deck number and the dealer’s fixed standing rules. In single-deck blackjack, surrender is recommended when you have hard 16 versus the dealer’s ace or 10.

Provided that the dealer hits soft 17, it is also recommended to surrender hard 15 against an ace. You should forfeit paired 7s against the dealer’s 10 in single-deck S17 blackjack. If one deck is in play and the dealer must hit soft 17, surrendering is advisable against tens and aces when you have 7-7.

In double-deck H17 games, surrender is advisable when you hold hard 15 and hard 16 against the dealer’s ace and 10. Paired 8s should also be surrendered against the ace in double-deck H17 blackjack.

Stay

As for shoe-dealt games, basic strategy suggests surrendering hard 16 against strong upcards such as 9, 10, and ace. The approach toward hard 15 in multi-deck variations depends on the dealer’s fixed rules for drawing and standing. You surrender the 15 against the dealer’s 10 in S17 variations and against the 10 and the ace in H17 multi-deck blackjack.

Hard 16 Consisting of Paired 8s

If you have read CasinoGuardian’s blackjack guide carefully so far, you probably remember that the rule of thumb of basic strategists is to always split pairs of 8-8 rather than forfeiting them despite the fact this is still a hard total of 16. Some gambling authors recommend surrendering the pair of 8s versus high dealer upcards like 10, K, Q, and J.

Regrettably, this is a major mistake, and here is why. The dealer undoubtedly has an advantage over you when you hold 8-8 versus a ten-value card. He or she would arrive at standing totals 17 through 21 77% of the time on average.

What adds insult to injury is that the dealer’s probability of busting when starting with a ten-value card is rather small at 23%. A pair of 8-8 will cost you money no matter how you approach it but splitting is recommended because it reduces your losses the most. With 8-8, you have a great opportunity to turn a terrible stiff 16 into two brand new hands starting with an 8 each. This improves your chances of forming a good hand and beating the dealer.

Assuming you play standard six-deck S17 blackjack where you can resplit to up to four hands and double down after you split, your 8-8 will lose against the dealer’s ten-value card 77 hands out of every one hundred hands and win 23 times out of every one hundred hands. However, your win rate improves to 38 hands out of every hundred rounds when you split your 8-8.

Let’s suppose you are flat betting £1 per hand for simplicity’s sake. If you merely hit the pair, you will lose £77 and win £23 every one hundred hands on average. This makes for an average net loss of £54 in the long run. Meanwhile, if you consistently split your 8-8 versus the dealer’s ten-value card, you will lose £62 and earn £38.

Your net losses drop to 2 x £24 = £48 per every one hundred hands in this case. This may not sound like a significant improvement but you are still losing £6 less compared to drawing or staying on your pair of 8-8. Meanwhile, if you choose to surrender this pair, as some gambling authors advocate, you will net losses of £50 per every one hundred rounds on average (you lose only half your original wager when surrendering).

Therefore, consistently surrendering your pair of 8s versus the dealer’s 10 turns out to be £2 more expensive than splitting over the long haul. At this point, it is pretty much obvious you are in a losing spot when holding 8-8 no matter how you decide to play it out.

The bottom line is you will save more money by splitting in the long run compared to surrendering or the other possible plays. The only consolation of blackjack players in such instances is that they have made the mathematically optimal decision when dealt a long-term loser like stiff 16.

You can compare the expectation of each basic strategy play with paired 8s and 7s against the dealer’s 10 upcard below. The calculations are courtesy of mathematician and gambling expert Michael Shackleford, known as the Wizard of Odds.

Hitting-0.539826Hitting-0.466307
Splitting-0.480686Splitting-0.657268

As with all rules, there are always exceptions, however. Paired 8s should always be split unless one is playing shoe games and double-deck blackjack where the dealer must hit soft 17. Under these playing conditions, the odds favour surrendering the pair of 8s rather than hitting when the dealer shows an ace.

Exceptions are also made for paired 7-7 in single-deck blackjack. When the dealer must stand on all 17s, you surrender the 7-7 against a 10. Provided that the dealer must hit soft 17, basic strategy recommends you to surrender this pair whenever you are up against a 10 and an ace.

Odds and Probabilities

Players need to know what their odds are in case they happen to have a total value of 14, 15, or 16 in their hand as this will help them make better decisions. The following odds are accurate proving that the game is played with more than one deck and that gamblers decide to hit. If they have a 14 hand, the chance that they will go bust is 46%, and if the total of their hand is 15 – 54%.

In cases when they get unfortunate and get a total of 16, their chances of going bust are 62%. The worse-case scenario is when players get 19 or 20 as this leaves them with more than 85% chance of going bust. The good news is basic strategists never draw to hard 19 and hard 20 so their chances of busting with these totals are practically nil. Logically, the higher the total of the cards in the players’ hand, the more they are likely to bust by taking a hit.

Conclusion

Blackjack Hit Or Stay Chart

Having to deal with a 14, 15, or 16 hand is a big challenge which requires a lot of preparation and a good strategy and even then, players’ success is not guaranteed and they can only hope that the odds will be in their favour.

However, if they follow a strategy or choose the option to surrender, any of these choices will lead to the least amount of money they will lose. Once players find themselves in a bad situation, they should consider how to get out of it with minimal money losses instead of how to win the hand as in many cases this only pushes them to certain doom.

Blackjack is one of the very few casino-banked card games where the decisions players make have a direct impact on their long-term chances of winning and preserving their bankrolls. Whether you make the correct plays or not will ultimately determine whether you emerge as a long-term winner or loser.

When you join a blackjack table, the two most fundamental playing decisions you are facing are whether to hit or stand on your hand. Ironically, these two decisions rank last in the order of plays you can exercise at the blackjack table.

The reason for this is simple – unlike surrendering, splitting, and doubling, you can hit or stand on hands that comprise any number of cards whereas the other moves are possible only on two-card totals. Both plays are accompanied by specific hand gestures which differ depending on whether you join a shoe-dealt table or a pitch game.

The great thing about blackjack is that the game combines elements of luck, skill, and strategy. There is no need to rely on gut feelings in order to make the correct move. All you have to do is memorize basic blackjack strategy. It gives you the foundation of becoming a successful blackjack player by telling you when to hit your hand and when to stand.

Hitting a Hand in Blackjack

A new round at the blackjack table starts with everyone receiving two cards that comprise their starting hands. This includes the dealer who normally receives their first card up while their second card is dealt face-down. The players would either receive their two cards face-up in shoe-dealt blackjack or face-down in pitch games where only one or two decks are in play.

At this point, each player takes a good look at their initial two-card hand, checks the dealer’s exposed card, and decides whether to take a hit or not. Hitting is the first most common decision one makes at the blackjack table. It involves the player requesting additional cards on their initial hand.

Hit

In multiple-deck games dealt out of a shoe, the player indicates they want to hit either with a beckoning gesture with their finger or by tapping the felt next to their two cards. In pitch games where you receive your cards face down, a hit is indicated by lightly scraping the felt with your two cards.

Players are allowed to take as many hits as they like unless the last card drawn to their hand causes it to break, i.e. go over 21. You can hit any total, with the exception of pat blackjacks which automatically stand.

The main reason for drawing additional cards is to try and improve the value of your hand. Your hitting decisions are influenced by two factors – the current total of your hand and the upcard the dealer is showing.

Standing on a Hand in Blackjack

Standing on a hand is practically the opposite of hitting. The player is satisfied with their current hand value and declines additional cards from the dealer. Similarly to hitting, this decision must be designated with a physical gesture for the purpose of hindering cheaters and preventing misunderstandings on behalf of the dealer and surveillance.

This physical motion involves waving your palm horizontally over your two cards in shoe-dealt games. The gesture is different in single-deck and double-deck games where standing is indicated by sliding the corners of your cards under the chips you have originally placed in your betting box.

Forced Standing Rules for Dealers and Their Variations

Unlike blackjack players, the house representative who deals the cards does not make any decisions when playing out their hand. Instead, blackjack dealers draw cards or stand on their hands according to the forced rules specified by the gambling establishments.

These forced dealer rules vary depending on the gambling hall and the blackjack table you play at, but are generally classified into two main groups. The dealer is either required to draw to 16 and force-stand on all totals of 17 or must draw to 16, stand on hard 17 and hit soft 17. The dealer standing rule is printed on the layout, which makes it easy for players to distinguish what table they are playing.

Which of the two dealer rules is better from the perspective of the player, though? To answer this question, we must first explain what a soft 17 is. This is a hand that contains an Ace whose value is flexible, i.e. it can be either 1 or 11, like in the following two examples – A-6 and A-2-4. Due to the fluctuating value of the Ace, one such soft hand practically has two totals, 7 and 17.

The dealer forced standing rules should be always taken into consideration because they have a direct impact on basic strategy as well as on the house edge. A total of 17 is not strong enough in blackjack where the average winning hand totals 18.5. A dealer who hits soft 17 is less susceptible to exceeding 21 and thus, losing because of the flexible value of the Ace.

If a higher-ranking card is drawn, the dealer’s Ace will count as 1. This practically makes it impossible for them to bust by taking one more card. However, if they happen to catch a small card like a deuce on the next hit, it gets them into the safe zone and they can outdraw the player, who always stands on hard 17 according to basic strategy.

Blackjack Hit Or Stay Chart Printable

A dealer who hits soft 17 (H17) increases the house edge by 0.22%. This may seem like a small increase in the casino’s advantage but nevertheless, it leads to higher hourly losses in the long term for the basic strategy player.

Assuming you play at a full table where you flat bet at the minimum of $5 and go through 60 hands per hour on average, you will lose roughly ($5 x 60 x 0.22)/100 = $0.66 per hour due to the soft 17 rule alone.

Of course, these figures apply only over the long run where thousands of hands are involved. Nevertheless, a smart blackjack player always favors tables where the dealer stands on all 17 over those where they hit soft 17.

Key Basic Strategy Plays for Hitting and Standing

Basic strategy tells blackjack players when it is the correct time to hit and when they should stand, among other things. The decision is based on the upcard of the dealer and the player’s hand total. Basic strategy is proven to reduce the house edge, but some of the hitting and standing decisions it suggests also aim at minimizing the long-term losses players incur in unfavorable situations. With that said, you cannot overcome the house edge entirely with basic strategy alone.

The correct plays are influenced by a variety of factors which include the above-mentioned dealer forced rules, the number of decks incorporated into the game, and the possible rule variations at different blackjack tables.

The strategy is normally presented in a table format. Here are several of the most important standing and hitting decisions recommended by basic strategy for multiple-deck games where the dealer force-stands on all 17s:

  • Always hit totals 4 through 8 regardless of what card the dealer shows
  • Stand on hard totals of 12 if the dealer exposes small cards 4 through 6 and hit your hard 12 against all other dealer cards
  • Hit 16 against a dealer with a ten-value card or Ace, otherwise surrender if allowed
  • Always hit soft totals 13 through 17 and stand on soft 19
  • Stand on soft totals of 18 unless the dealer is showing high cards like 9, 10, and Ace. If so, hit your soft 18.
  • Stand on all hard totals of 17 or higher

Deviations from Basic-Strategy Hitting and Standing Decisions

Learning basic strategy is an absolute must for anyone who insists on becoming a winning blackjack player. With that said, basic strategy relies on limited information. It tells you the optimal plays you can make in any given situation after you have received your first two cards and have seen the dealer’s exposed card.

However, it does not take into account the way the composition of the deck or shoe changes as more and more cards are removed from play. These changes in composition are important because they have a direct impact on the house edge.

When to hit in blackjack chart

If more ten-value cards and Aces remain to be dealt, the edge swings over in favor of the player and vice versa, the dealer has an advantage when the remaining shoe or deck is richer in small cards. Smart players have learned to exploit this peculiarity of the game by keeping track of the ratio of high to low cards that remain to be dealt.

When To Hit In Blackjack

This is known as card counting. The player keeps a running count as each card is dealt out of the shoe and then converts it into a true count. This conversion is necessary for shoe games and involves the division of the current running count by the number of decks that remain in play.

A high positive true count indicates the shoe is rich in high cards and vice versa, a negative true count means more small cards are still in play. Using this information, well-versed players would deviate from basic strategy for certain hitting and standing decisions. The plays suggested by the strategy are based on a neutral deck or shoe and are no longer optimal after the composition changes.

A Couple of Examples for Hitting and Standing Deviations

Blackjack pros resort to using indices for their playing deviations. An index is a number that tells you at what true count you must diverge from the basic strategy. Let’s use hard 12 against a dealer with a deuce as an example just to give you a better idea of how playing deviations for hitting and standing work.

Blackjack Hit Or Stay Chart

A basic strategy chart for multiple-deck games under the S17 rule recommends you to hit your 12 against a 2. However, this play is no longer optimal once you arrive at a true count of +3. Now, there are more tens and face cards you can bust with. Therefore, you must deviate from basic strategy and stand on your 12 against the 2 when the true count is +3 or higher.

Another example is a hand of hard 16 against a dealer with a 9 as their upcard. According to basic strategy, you must hit your hard 16 against the 9 if surrender is unavailable. Unfortunately, this decision is a bad one on high positive counts of +5 or above. Respectively, the player stands (the pun was unintentional) better chances of winning if they refrain from drawing more cards because hitting is more likely to break their 16 in shoes that are rich in tens.

And one final example with a hard 13 versus a dealer showing a 3, in which case you should stand according to basic strategy. This may be a good idea in a neutral shoe but it becomes unprofitable on negative counts.

Blackjack Hit Or Stay Chart Printable

The index for this hand is -2, which is to say you deviate from basic strategy when the true count drops to -2 or lower by choosing to hit instead of standing. At this point, there are more small cards than high cards to help you improve your hand and minimize the risk of breaking it.

Hit Or Stand Blackjack Training

Playing deviations are great not only for hitting and standing but for all other possible moves in blackjack, like doubling, splitting, surrendering, and buying insurance. Not only do these deviations enable the player to generate more EV in the long term but they also reduce risk and help you tame variance.

With that said, it is impossible to use them without committing basic strategy to memory first, so we suggest this is where you start if you take your blackjack game seriously.
