This section will focus on betting systems. Betting systems can be distinguished from other systems in that they are not believed to alter the likelihood of winning a particular hand. Instead they involve varying one's bet from one round to another with the goal of betting more on the winning rounds and less on the losing ones.
Betting systems thus depend on methods for predicting which hands are more likely to win, and which hands less likely — before the deal takes place — and betting more or less accordingly. Card counting involves a betting system because part of the player's advantage comes from betting high when the odds are in the player's favor and betting low when the odds are in the casino's favor.
It also involves a playing system, since it uses the basic strategy to minimize the casino's advantage, and it deviates from the basic strategy in certain cases when justified by the count. I will discuss six blackjack betting systems here.
They include: 1 increasing one's bet after an improbable series of losses because a win is due, the classic example of the gambler's fallacy, 2 negative progression betting systems such as the Martingale system and 3 chasing. None of the systems are normative from an expected value point of view except to the degree that they lead to higher or lower average bets. It is also important to note that while all of the first three systems will sometimes be used, none of them are common.
Often they are explicitly condemned whereas all of the last three systems appear to be the norm among experienced players and are taken to be signs of a good blackjack player. This is surprising since the first three strategies are most commonly associated with gamblers' false beliefs in the literature.
As far as I am aware no previous research has identified the overwhelming preference among experienced blackjack players and in my experience, gamblers more generally for increasing bets when winning as compared to increasing bets when losing. Although the gambler's fallacy may be the best known false belief commonly held by gamblers, and it does influence violations of basic strategy, it plays almost no role in blackjack betting strategies.
Experienced players, in particular, almost universally endorse a system, described below, that may be seen as directly contrary to this fallacy. Another well-known betting system that involves increasing the size of one's bets when losing is the Martingale system, a member of a class of negative progression betting systems. They are called negative progression rather than positive progression, because the bet is increased after a loss rather than after a win.
With the Martingale system, players start with a large amount of money and begin with a unit bet, doubling it each time until they win, then returning to the base bet. Each time the player wins, he or she is ahead an additional unit bet. Players who use this strategy reason that the odds are small that the casino will win several times in a row, and infinitely small that the casino will keep winning forever. These two claims are true.
As long as the players have enough money to keep doubling their bet, and the casino's maximum bet is high enough, they will eventually win. This strategy is often co-expressed with the gambler's fallacy. So, for example, a gambler may wait for red to occur three times in roulette before placing their first minimum bet on black.
At the same time, the system itself should not be taken as an example of the gambler's fallacy. The gambler's fallacy concerns events that have already occurred which are incorrectly judged to affect future probabilities. Martingale systems concern series of future events for the casino that are, in fact, increasingly improbable the longer the required series.
Thus, Martingale systems, unlike common expressions of the gambler's fallacy, do usually work. That is, players will win more often than they will lose. The problem occurs when the player experiences the inevitable losing streak i. In such cases, the cost to the player will be high enough on average to deplete all of the smaller wins, plus the loss of the casino's expected return on the total amount bet.
Furthermore, the success or failure of Martingale involves high variance, so that an individual's experience with it over even several months of gambling may result in more money won than lost, providing many with apparent confirmation that the system works. Even then, if a player has had one big loss that cancelled out all winnings, she or he can often chalk this up to a failure to stick to the system. A player can also reasonably chalk a loss up to bad luck, since one or two losses out of several wins are not, in themselves, enough to know whether it is a failure in the system or simply the downside of random variation that led to a net loss.
As a result, many novice- and intermediate-level players use Martingale-type systems, but nearly all long-time players have learned not to use it, either from personal experience or vicariously through the experience of others. I encountered a few players who stopped using this system while still believing it probably works. Players I have spoken with who continue to use this system do not seem to recognize this risk. The Nepalese man, Arvind, for example, told me very confidentially and confidently that he used this system for blackjack.
But you need a lot of money. Most players who use this system use it in roulette, not blackjack, and until this point I had never had anyone say outright that they believed blackjack could be beaten using such a system. There are two reasons the system might be less common in blackjack. Second, even though blackjack provides relatively good players with a higher expected return than roulette, much of this benefit comes from the opportunity to split and double down , and from the three-to-two payout for a blackjack.
The probability of losing an individual round in blackjack is actually higher than in roulette, even for the perfect basic strategy player, and so the system will fail more often than in roulette. There are several similar systems to Martingale that involve systematic increases in bets with losses and decreases with wins.
These systems are generally uncommon in blackjack, however, so they will not be discussed further. Rather than being a betting system, the term chasing usually implies a loss of control. It is the act of betting higher and higher amounts in the hopes of recouping unwanted losses. As with Martingale, chasing works more often than not, since just one win will be enough to recoup the losses, but in the event that it does not, and the gambler continues to lose until the losses can no longer be recouped with a single bet.
The consequences can be devastating. I did not meet any blackjack players in Indiana who recommended chasing, though I observed what appeared to be chasing a few times, and two players admitted they were doing so. Experienced players who were not in the act of chasing universally condemned it, while many of these same gamblers admitted they occasionally lost control and did it.
Since chasing usually works, it makes sense that it would be appealing specifically after a gambler has lost more than they feel they can afford to lose. Chasing offers a way out. It also makes sense that after a gambler has lost even the available money with which to chase, and subsequently come to terms with that loss, that they would see chasing as the potentially devastating practice that it is.
Players using this system wait for a particular outcome to occur significantly more often than usual and then bet on it to occur again. When blackjack players use this system, it seems to come from a belief in patterns of luck.
Nearly all experienced players increase their bets after wins and decrease them after losses, often with the explicit justification that they are hot. Indeed, many players will not sit at a table until they have seen whether the dealer is hot or cold. Unlike the three previous systems that involve increasing bets after losses, the belief that luck runs in identifiable streaks and can be bet on to the player's advantage, appears to be shared by a clear majority of experienced blackjack players.
Many players believe that betting high when the cards are hot and low when the cards are cold is the single most important factor to winning in blackjack. While they accept that long-term probability favors the casino, many of these players believe they can use their knowledge of streaks to take advantage of short-term fluctuations in luck, and by doing so gain an advantage over the casino.
Far more common in blackjack than Martingale and other negative progression systems are positive progression systems whereby players systematically increase their bets after wins. Usually this involves increasing bets by some fraction of the previous bet until a loss occurs, then either returning to the base bet or reducing the bet by the same fraction that it was increased. Often the maximum bet size depends on the total amount of money the player has won or lost during the playing session such that the player will progress to higher maximum bets the more they have won.
The systems may be more or less codified and depend more or less on intuition from one player to another. Positive progression betting usually co-occurs with a belief that outcomes run in streaks as discussed above, and it is difficult to separate one from the other. This betting system tends to be the behavioral expression of the belief in streaks.
Many players bet more when they are ahead overall for the day. It should be noted that not only are casino gamblers more risk-seeking after winning, but they tend to believe such a strategy is normative. It's the only way you'll ever really win. You have to bet big when you get some money from the casino. Perhaps the reason for common violations of the basic strategy is that the players have other goals in addition to or instead of maximizing their winnings.
One question I had, then, was what other reasons patrons had for playing the game. What were their goals? Along with the hope of winning, there are three main goals that the game of blackjack appears to satisfy. All three may be interdependent, though, and I was unable to clearly distinguish between them. The first goal was simply to have a good time.
I mean, what do you do in Indiana? And at least three others stated that they gambled for enjoyment, not because they expected to win. A second reason, which cannot be cleanly distinguished from the first, may be the desire for social interaction.
Players did not talk about this, but the behavior at the tables and on the shuttle suggests that part of the experience of the game involves friendly interaction with other people. Shuttle drivers and patrons often know each other by name and they speak about other players and drivers who are not present by name as well.
People at the table often come to the casino together or know one another from past casino experiences. Players also frequently comment on other players' cards, complimenting them when the cards are good, sympathizing when the cards are bad, wishing one another luck, and offering advice on how to play. Although players at some tables did not speak at all, for the most part blackjack appeared to be a friendly social experience.
The desire for fun or for social interaction notwithstanding, the hope of winning seems to be a constant characteristic of blackjack players. A distinction should be made here between players who expect to win, and those who expect to lose but still hope to win. It became apparent from different conversations that many players expected to win. One floor supervisor said that many people played in order to make a living, although I could not tell how successful such people were or what fraction of the patrons had this in mind.
A dealer said that 99 per cent of players thought they had a system to beat the casino. Several players also told me that they had winning systems. In my experience, though, most players know the odds are against them and that they will probably lose. Nonetheless, I never encountered anyone who gave me an indication that they did not at least hope to win, and conversations frequently referred to past great wins by the speaker or people who were observed to win large amounts.
While having fun and social interaction are certainly part of the experience, the hope of winning, even among gamblers who know the odds are against them, also plays an important role. The interaction of these goals can have important repercussions and could explain a number of violations of basic strategy.
Another player explained that she never splits her tens because it makes everyone else at the table so upset, even though she sometimes likes to do it when she is playing alone. Splitting is much more fun and twos often turn into a good hand, so why not. Finally, it is worth noting a possible relationship between the betting systems discussed in the previous section and gambler utility.
The first three betting systems, all of which call for higher bets when losing, have unique consequences on winning experience from the latter three systems, all of which call for higher bets when winning. Using these latter systems, players will actually leave the casino as winners less often than when using Martingale-type systems or chasing, since they will tend to bet higher amounts specifically when they are ahead, increasing the probability that they will lose all of their winnings.
At the same time, the average and maximum size of their winning sessions will be larger, since on the less common occasions when these gamblers do end their gambling sessions as winners, they were making larger than usual bets. Finally, the average and maximum size of their losing sessions will tend to be smaller, since on the occasions when these gamblers are losing, they will lower their bet sizes, thus risking less while also reducing the probability of breaking even.
The differential structure of winning and losing experiences may play a significant role in why increasing bets when winning and decreasing them when losing is far more popular than the opposite set of strategies, particularly among the most experienced players. An occasional big win, while avoiding costly large losses, may have more utility to the gambler than an occasional big loss with few if any big wins, even if the favored strategies result in fewer winning sessions and even if both sets of strategies have the same, slightly negative, expected value.
Indeed, Turner personal communication, observed that positive progression betting systems create a payout structure similar to that built into the design of slot machines, the most popular casino gambling activity of all. Perhaps the utility of an occasional big win outweighs the cost of frequent though affordable losses, even if the objective sum of these losses over the long term is greater than the sum of the wins.
It should be recognized that experienced players conform well to the basic strategy, but they also make a number of choices that systematically violate it. As such, it is worth distinguishing these folk- or pseudo-basic strategies from the actual mathematically-derived basic strategy. The violations of basic strategy seem to involve a partial misunderstanding or ignorance of what basic strategy really means, as well as a belief in the norms at the table, which occasionally differ systematically from basic strategy.
Proficient card counters are exceedingly rare. Nonetheless, experienced players use a number of techniques related to past cards removed from the shoe and incorporate basic tenets of card counting, though these systems probably hurt the players more than help them in terms of expected value.
Just as the folk conceptions of basic strategy might be termed pseudo-basic strategy, these folk conceptions of card counting might be termed pseudo-card counting, in order to distinguish them from the more precise mathematically-derived methods. There are also a wide range of practices and beliefs related to the ability to influence the outcome of cards. These sometimes include idiosyncratic methods such as carrying a lucky charm or circling one's chair at the beginning of every shoe.
More often they include practices acknowledged by the group to work, such as having a particular person cut the cards, or tapping on the table when a player gets an ace to wish them luck in getting a blackjack. The most common practices and beliefs have to do with a concern with proper order.
Players will pay attention to how many hands are dealt at the table, the playing strategies people are using and how well people are playing, and try to keep this all consistent if the gamblers are doing well, or change it if the gamblers are doing poorly. They will urge others to play consistently and to play according to group norms with the explanation that to do otherwise is bad for the entire table. Another factor affecting blackjack strategies are betting systems that use previous sequences of wins and losses to determine how to bet.
One set of strategies calls for increasing one's bets when losing and decreasing one's bets when losing. A second set of strategies calls for increasing bets when winning and decreasing bets when losing. Although all systems are relatively well known, the first set of systems are quite rare among experienced players except, perhaps, chasing , and none of them are condoned as good strategies, whereas the second set of systems are widely practiced and condoned among even the most experienced players.
For the most part, blackjack players seem concerned with maximizing their winnings. However, they also have additional goals. These include a desire to have fun or to be entertained, a desire for social interaction and unique goals related to both the hope of winning and the subjective experience of winning that cannot be reduced to expected value.
At the beginning of the article it was noted that a number of researchers see gamblers' false beliefs about winning and their suboptimal strategies as an important factor in why so many people gamble and why some people become problem or pathological gamblers and others do not. The implication is that the biased or irrational cognitions of the gambler are the source of these false beliefs and suboptimal strategies.
These claims suggest three important questions: 1 Do frequent gamblers really tend to have false beliefs about winning and suboptimal strategies for doing so? And 3 are the false beliefs and suboptimal strategies really the consequence of biased or irrational thinking on the part of the gambler? I will consider each of these questions with reference to the research findings.
Before delving in, however, two caveats are important. First, gamblers are a diverse group and blackjack players are no exception. These false beliefs likely directly contribute to their decision to gamble and to their difficulty in stopping. Furthermore, the source of these false beliefs may often be the biased or irrational cognitions of the individual, either through the expression of traditional heuristics and biases or through motivated reasoning.
They gamble either because they have a system for winning which seems reasonable, given the available information about the activity, or because they have other reasons for gambling besides the expectation of winning money. This discussion will focus on the group most commonly observed during the ethnographic research, and this group does not fall neatly into either of these two extremes.
Second, the quality of the data obtained during the ethnographic research does not allow me to categorically answer any of these questions, particularly the second. I have few means by which to know whether blackjack players' false beliefs and suboptimal strategies led to their choice to play blackjack, and I have even fewer means to assess causes of problem gambling behavior that were not a category of inquiry for the study.
At the same time, the ethnographic findings have implications for all three questions, and these implications will be considered here. At the same time, it should be recognized that most of these false beliefs have only a minor impact on the player's expected return.
This may be particularly true since deviations from basic strategy seem to be limited to hands for which violating basic strategy is the least costly. Furthermore, the one set of strategies that have the largest impact on the players' expected returns — betting strategies that influence average bet sizes — have important consequences for the gambling experience that may provide utility beyond expected value.
Thus, while blackjack players may be incorrect to believe increasing their bets after wins increases their chances of being a long-term winner, these strategies may have survived and thrived specifically because they tend to contribute to other positive features of the gambling experience. As such, the long answer to this question may be that gamblers have both true and false beliefs and better and worse strategies, but the false beliefs and suboptimal strategies tend not to have serious negative implications and may provide benefits and safeguards about which not even the gambler is consciously aware.
This research suggests that experienced blackjack players have a rich set of strategies and beliefs, many of which have unquestionably developed in the context of the blackjack playing experience. Their strategies and beliefs, both true and false, provide part of the structure of the blackjack playing experience and undoubtedly contribute to the utility of playing blackjack. In part at least, the game is enjoyable because it involves learned skills that more experienced players actually use.
This is not simply the illusion of control Langer, or the illusion of skill, even if the consequences of the strategies do not improve one's chances of winning. For example, although I studied card counting, I might nonetheless make systematic errors in keeping the count that lead me to raise my bets and to deviate from the basic strategy in cases where I should not.
If I do this frequently enough, I may perform worse than a player who simply bets the minimum and plays by the basic strategy. Even if this is the case, my decisions are still based on a trained skill, and the application of this skill significantly contributes to my enjoyment of the game and the utility I get from playing. Similarly, experienced blackjack players may be better than beginners at noticing patterns in outcomes and these likely influence their probability of winning during a particular gambling session because of their corresponding betting systems.
Also, they probably do apply unique skills that I, for example, do not have for deciding when to take cards or not take cards based on which cards were removed from the deck. And all of this undoubtedly contributes to their enjoyment of blackjack and to their decision to play, just as their correct beliefs and working strategies do.
Do these strategies and beliefs contribute to problem or pathological gambling? False beliefs and suboptimal strategies likely contribute to problem gambling in three ways. Second, also from an impulse-control perspective, they make it more likely that the player becomes committed to the game to a point when their own best judgment and self-control, which originally may have been adequate to stop them from gambling, is not adequate any longer.
Third, to the degree that these false beliefs lead gamblers to incorrectly believe they can win, they make it more likely that gamblers will lose more than they can afford, with serious consequences. At the same time, most of the gamblers I encountered sincerely enjoy the blackjack playing activity and seem to have developed healthy strategies for playing over an extended period without risking too much.
Specific playing strategies, while not perfect, are correct more often than not, and the endorsed betting systems seem designed to specifically ensure that players will not lose more than they can afford while still having the chance to occasionally experience a big win, which for many gamblers may be precisely what attracts them to the gambling activity.
This, for me, is the most important question. An implicit assumption in much gambling research is that their suboptimal strategies and false beliefs are consequences of shortcomings in the reasoning processes of the individual; correct their biased and irrational cognitions and the problem will be solved, this view suggests.
The current research suggests that the false beliefs are, to an important extent, the consequence, not the cause, of gambling activity. The most experienced players have a rich set of strategies and beliefs that they appear to have learned during the gambling experience. In my view, these strategies and beliefs are as rational and unbiased as other strategies and beliefs commonly used during decisions made throughout much of a healthy individual's life. That is, they are neither rational and unbiased, nor irrational and biased.
Rather they involve the best judgments available to the players given their gambling experiences and the available information, with occasional motivated reasoning mixed in for good measure. It was not a matter of unbiased or rational cognition any more than it was a matter of biased or irrational cognition that led me to the belief that I could make good money counting cards in blackjack, or to the subsequent belief that I could not.
Nor is it a matter of unbiased or rational cognition that led me to the conclusion that these players do not improve their expected return by increasing their bets after a win, or that led them to their conclusion that they can. Rather, these beliefs depend importantly on complex structural features of the environment within which they and I developed our strategies and beliefs.
These include not just the physical structures, but also the information available, the belief systems of other members of the community and the complex experiential feedback given the environmental structure and dynamics. I have no empirical evidence that the cards do not get hot or cold in ways that are predictive of future outcomes.
I accept that they do not because of my training and experience outside the gambling domain, just as the gamblers accept that they do because of their training and experience inside the gambling domain. I have never been able to convince an experienced blackjack player who holds these beliefs that they are wrong and I have tried several times , but in my view this is not because they are being irrational.
Indeed, they can often provide better empirical evidence and rational arguments than I can. I am sometimes forced to admit that I take it on faith that hot and cold streaks, beyond the unpredictable expectations of random variation, do not occur.
The implication here is that the persistence of erroneous beliefs held by gamblers may depend more on characteristics of the gambling environment than it does on the irrational or biased quality of the gamblers' reasoning. Indeed, once the structure and dynamics of the gambling environment are taken into account, many of the strategies and beliefs that originally seem biased or irrational may be seen to be inseparable from the gambling context, including its sociocultural context, and to be both rationally and empirically justified.
With an advantage of one or two per cent, even skilled card-counters will usually end up significantly down at some point during their playing period just due to normal random variation. Among mathematicians interested in gambling, the study of risk management, or the proportion of one's bankroll that should be risked given a particular advantage and a particular variance, is something of a sub-field in its own right.
The basic strategy indicates the best way to play each hand without using a counting system or cheating , assuming the player's goal is to maximize expected return. It is often referred to as playing by the book. It depends on the make up of both the player's cards and the dealer' s up-card, and it varies slightly depending on the particular blackjack rules in one casino or another.
In addition to being the name of the game, blackjack is a two-card 21 i. It beats all other types of 21 i. If the player gets a blackjack the casino pays the player three to two. Busting is the act of getting a point total higher than 21, which results in an automatic loss. If both the player and the dealer bust, the player still loses. This is the only tie in which the player loses and is the source of the casino's advantage in blackjack. Busting hands or bust hands are hands lower than 17 that will exceed 21, and thus bust, if they are hit with a That is, they are hand totals from 12 to When the dealer has a two through six showing, these hands are also commonly called busting hands, since it is often assumed that the dealer has a value hole card and these are in fact the up-cards for which the dealer is most likely to bust.
Card counting is a method for keeping track of past cards removed from the deck in order to give the player an advantage. Card-counting systems usually require the player to 1 assign plus and minus values to low and high cards, respectively; 2 add these values as the cards are removed from play; 3 normalize this sum based on the number of cards remaining to be dealt; and 4 adjust playing and betting decisions according to the this normalized number. Under ideal circumstances, using such systems can give the player an advantage over the casino.
The dealer works for the casino. Players win or lose depending on how their cards perform against the dealer's cards. The dealer must play according to predetermined rules set by the casino that do not depend on the players' hands. Usually these rules require the dealer to hit with 16 or less and to stand with 17 or more, although hitting with a soft 17 is also common.
Players who double down are required to double the size of their initial bet. In turn they get exactly one additional card. Players have the option to do this after the deal, but only with their initial two cards or with the new two-card hand created after splitting. First base refers to the first person to the dealer' s left.
This is the first person to play after the deal. Third base refers to the player closest to the dealer's right. This is the last person to play before the dealer. Hands without an ace or hands for which the ace can only legally be used as a one are called hard hands. If the ace can be used as either an 11 or a one, this is called a soft hand.
For example, if the player or dealer has an ace and a five this is referred to as a soft 16 not a soft six. Players can hit this hand without risk, since even receiving a 10 would only make the hand a hard Hitting is the act of taking an additional card. Players tap their fingers or move their hands toward themselves to indicate that they want to hit. The hole card is the face down card in the dealer's hand. Players do not get to see this card until after they have finished making their play choices.
If the dealer has an ace showing, players have the option to place half their initial bet onto a special spot to take insurance. The dealer then looks at his or her hole card. If there is a value card, thus giving the dealer a blackjack, the insurance bet pays two to one, thus covering the initial bet. If the player has a blackjack when the dealer has an ace up, the player has the option to take even money.
That is, the player can win exactly the amount of their original bet, before the dealer checks his or her hole card for a blackjack. This compares to not taking even money and either winning three to two for the blackjack, or pushing and winning nothing if the dealer ends up having a blackjack.
Taking even money turns out to be monetarily identical to taking insurance. Both plays have a negative expected return. Table games are arranged in an oval so that all of the players are on the outside facing dealers who are inside. The inside of this oval is known as the pit. Pit bosses are the highest level of manager within a pit. Floor supervisors are similar to pit bosses except that their domain is smaller.
They are responsible for supervising anywhere from one to four tables depending on the game and the time of day, whereas the pit boss is responsible for the entire pit. When the player and the dealer tie have the same point total this is called a push. The player neither wins nor loses. The shoe is a plastic box that holds the decks after they have been shuffled. The dealer draws cards from the shoe to deal to the players.
Blackjack games use from one to eight decks. One or two deck games do not use a shoe; four, six, and eight deck games do. If the first two cards dealt to a player are the same including any two value cards , the player has the option to double his or her bet, split the two cards and play them as two separate hands. Players can split the same card up to three times in a single hand thus playing up to four separate hands.
Players can only split aces once, and they are not allowed to hit after each ace is made into a two-card hand. If either or both of the split aces get tens, they are not treated as blackjacks but instead as standard twenty-ones. That is, they lose to a dealer blackjack, push to a dealer's 21, and only payout one to one, rather than three to two. Players stand when they have finished making all play choices, except when they bust. In other words, standing involves the choice to stop taking additional cards.
Players signal this by holding their hand flesh and blood, not cards horizontally above their cards and waving it back and forth. E-mail: w-bennis uchicago. Woodlawn Ave. Chicago, IL U.

Abstract A great deal of research on the psychology of gambling has been conducted that has looked at non-experienced gamblers in laboratory or classroom settings. Introduction Gambling is a large and growing industry in the United States and around the world Gu, ; Morais, Why ethnographic participant-observation research? My background in blackjack My own background and experience with blackjack has contributed importantly to my decision to study this particular game and to the lens through which I have interpreted and evaluated players' performances.
Background on blackjack Casino blackjack is a somewhat complicated game with its own vocabulary, as many as five types of choices per hand, significant consequences on one's chances of winning depending on these choices, and a variety of rules and norms surrounding play. Blackjack rules The goal of blackjack is to get a higher point total than the dealer without busting getting more than 21 points.
The common rule variations include: 1. Normative models Before discussing how people actually play blackjack, it is worth discussing how one might expect people to play blackjack assuming that their goal is to maximize expected winnings 1 or to minimize expected losses. The basic strategy The basic strategy indicates the best way to play each hand without using either a counting system or cheating.
Card-counting systems Card-counting systems are used by players to reduce the casino's advantage further, and under certain conditions, to give the player an advantage. Ethnographic findings The ethnographic findings are divided into five parts. Pseudo-basic strategy Of the 75 or so players I observed during my ethnographic work, not one used the basic strategy consistently.
Even money The most common exception to the basic strategy at the Indiana casinos seems to be taking even money with a blackjack when the dealer has an ace showing. Insuring good hands Another common play that violates the basic strategy is the decision to take insurance, which should never be made according to basic strategy.
Pseudo-card counting As with the basic strategy, a superficial knowledge of card counting is common, although it plays a less significant role in affecting playing strategies. Betting systems There are a number of systems, in addition to pseudo-basic strategy and pseudo-card counting, that players use in the belief that they increase their chances of winning. Negative progression betting systems Another well-known betting system that involves increasing the size of one's bets when losing is the Martingale system, a member of a class of negative progression betting systems.
Chasing Rather than being a betting system, the term chasing usually implies a loss of control. Positive progression betting Far more common in blackjack than Martingale and other negative progression systems are positive progression systems whereby players systematically increase their bets after wins. Betting with the house's money Many players bet more when they are ahead overall for the day. Do gamblers really play in order to maximize expected return?
Summary of research results It should be recognized that experienced players conform well to the basic strategy, but they also make a number of choices that systematically violate it. Conclusion: Implications for research into gambling behavior and problem gambling At the beginning of the article it was noted that a number of researchers see gamblers' false beliefs about winning and their suboptimal strategies as an important factor in why so many people gamble and why some people become problem or pathological gamblers and others do not.
Do frequent blackjack players really tend to have false beliefs about winning and suboptimal strategies for doing so? Do these false beliefs and suboptimal strategies contribute to their decision to gamble and to their progression from leisure gambler to problem gambler? Are false beliefs and suboptimal strategies really the consequence of biased or irrational thinking on the part of the gambler?
