For every bookmaker has a rule for what happens to a wager if it is placed on an event that ends up being abandoned for some reason. As with pretty much anything in countries like the UK, weather can have a massive impact on whether an event is likely to finish. Obvious examples include such things as lightning storms or flash floods, but snow flurries that make it impossible to see the markings on the pitch or the ball can also give the match officials pause for thought. Crowd safety will always be one of the first things that is taken into consideration by those who decide whether or not a match will be allowed to carry on.

Card counting with the mind is legal, although casinos in the US reserve the right to remove anyone they suspect of using the technique. Card counting is not illegal under British law, nor is it under federal, state, or local laws in the United States provided that no external card counting device or person assists the player in counting cards.

Still, casinos object to the practice, and try to prevent it, [23] banning players believed to be counters. In their pursuit to identify card counters, casinos sometimes misidentify and ban players suspected of counting cards even if they do not. In , Ken Uston , a Blackjack Hall of Fame inductee, filed a lawsuit against an Atlantic City casino, claiming that casinos did not have the right to ban skilled players. The New Jersey Supreme Court agreed, [25] ruling that "the state's control of Atlantic City's casinos is so complete that only the New Jersey Casino Control Commission has the power to make rules to exclude skillful players.

As they are unable to ban counters even when identified, Atlantic City casinos have increased the use of countermeasures. Macau , the gambling capital of the world and the only legal gambling location in China, [27] does not technically prohibit card counting but casinos reserve the right to expel or ban any customers, as is the case in the US and Britain.

Monitoring player behavior to assist with detecting the card counters falls into the hands of the on-floor casino personnel " pit bosses " and casino-surveillance personnel, who may use video surveillance "the eye in the sky " as well as computer analysis, to try to spot playing behavior indicative of card counting. Early counter-strategies featured the dealers learning to count the cards themselves to recognize the patterns in the players.

Many casino chains keep databases of players that they consider undesirable. For successful card counters, therefore, skill at "cover" behavior, to hide counting and avoid "drawing heat" and possibly being barred, may be just as important as playing skill. Detection of card counters will be confirmed after a player is first suspected of counting cards; when seeking card counters, casino employees, whatever their position, could be alerted by many things that are most common when related to card counting but not common for other players.

These include: [33] [34] [35]. Card counters may make unique playing strategy deviations not normally used by non-counters. Extremely aggressive plays such as splitting tens and doubling soft 19 and 20 are often called out to the pit to notify them because they are telltale signs of not only card counters but hole carding.

Several semi-automated systems have been designed to aid the detection of card counters. The MindPlay system now discontinued scanned card values as the cards we're dealt. The Shuffle Master Intelligent Shoe system also scans card values as cards exit the shoe.

Software called Bloodhound and Protec 21 [36] allows voice input of card and bet values, in an attempt to determine the player edge. A more recent innovation is the use of RFID signatures embedded within the casino chips so that the table can automatically track bet amounts. Automated card-reading technology has known abuse potential in that it can be used to simplify the practice of preferential shuffling —having the dealer reshuffle the cards whenever the odds favor the players.

To comply with licensing regulations, some blackjack protection systems have been designed to delay access to real-time data on remaining cards in the shoe. With card values, play decisions, and bet decisions conveniently accessible, the casino can analyze bet variation, play accuracy, and play variation. Bet variation. The simplest way a card counter makes money is to bet more when they have an edge. While playing back the tapes of a recent session of play, the software can generate a scatter plot of the amount bet versus the count at the time the bet was made and find the trendline that best fits the scattered points.

If the player is not counting cards, there will be no trend; their bet variation and the count variation will not consistently correlate. If the player is counting and varying bets according to the count, there will be a trend whose slope reflects the player's average edge from this technique. Play variation. When card counters vary from basic strategy, they do so in response to the count, to gain an additional edge.

The software can verify whether there is a pattern to play variation. Of particular interest is whether the player sometimes when the count is positive takes insurance and stands on 16 versus a dealer 10, but plays differently when the count is negative. Casinos have spent a great amount of effort and money in trying to thwart card counters. Countermeasures used to prevent card counters from profiting at blackjack include: [41] [42] [30] [43].

Some jurisdictions e. Nevada have few legal restrictions placed on these countermeasures. Other jurisdictions such as New Jersey limit the countermeasures a casino can take against skilled players. Some countermeasures result in disadvantages for the casino. Frequent or complex shuffling, for example, reduces the amount of playing time and consequently the house winnings.

Others, known as continuous shuffle machines CSMs , allow the dealer to simply return used cards to a single shoe to allow playing with no interruption. Because CSMs essentially force minimal penetration, they greatly reduce the advantage of traditional counting techniques. American mathematician Edward O. Thorp is considered the father of card counting. Although mathematically sound, some of the techniques described no longer apply, as casinos took counter-measures such as no longer dealing with the last card.

Also, the counting system described count is harder to use and less profitable than the point-count systems that have been developed since. Even before the publication of Beat the Dealer , however, a small number of professional card counters were beating blackjack games in Las Vegas and casinos elsewhere. One of these early card counters was Jess Marcum, who is described in documents and interviews with professional gamblers of the time as having developed the first full-fledged point-count system.

Another documented pre-Thorp card counter was a professional gambler named Joe Bernstein, who is described in the book I Want To Quit Winners , by Reno casino owner Harold Smith, as an Ace counter feared throughout the casinos of Nevada. And in the book Playing Blackjack to Win , Roger Baldwin, Wilbert Cantey, Herbert Maisel, and James McDermott known among card counters as "The Four Horsemen" published the first accurate blackjack basic strategy and a rudimentary card-counting system, devised solely with the aid of crude mechanical calculators —what used to be called "adding machines.

From the early days of card-counting, some players have been hugely successful, including Al Francesco, the inventor of blackjack team play and the man who taught Ken Uston how to count cards, and Tommy Hyland , manager of the longest-running blackjack team in history. Ken Uston, though perhaps the most famous card-counter through his 60 Minutes television appearance and his books, tended to overstate his winnings, as documented by players who worked with him, including Al Francesco and team member Darryl Purpose.

In the s and s, as computing power grew, more advanced and more difficult card-counting systems came into favor. Many card counters agree, however, that a simpler and less advantageous system that can be played flawlessly for hours earns an overall higher return than a more complex system prone to user error. In the s Ken Uston was the first to write about a tactic of card counting he called the Big Player Team. The book was based on his experiences working as a "big player" BP on Al Francesco's teams.

In big-player blackjack teams a number of card counters, called "spotters," are dispatched to tables around a casino, where their responsibility is to keep track of the count and signal to the big player when the count indicates a player advantage. The big player then joins the game at that table, placing maximum bets at a player advantage. When the spotter indicates that the count has dropped, they again signal the BP to leave the table.

By jumping from table to table as called in by spotters, BP avoids all play at a disadvantage. In addition, since BP's play appears random and irrational, they avoid detection by the casinos. The spotters, who are doing the actual counting, are not themselves changing their bet size or strategy, so they are relatively inconspicuous.

With this style of play, a number of blackjack teams have cleared millions of dollars through the years. The publication of Ken Uston's books and of his landmark lawsuits against the casinos, both stimulated the growth of blackjack teams Hyland's team and the first MIT team were formed in Atlantic City shortly after the publication of Million Dollar Blackjack and increased casino awareness of the methods of blackjack teams, making it more difficult for such teams to operate.

Hyland and Francesco soon switched to a form of shuffle tracking called "Ace sequencing. This made it more difficult for casinos to detect when team members were playing with an advantage. In , members of the Hyland team were arrested for ace sequencing and blackjack team play at Casino Windsor in Windsor, Ontario , Canada.

It was documented in court that Nevada casinos with ownership stakes in the Windsor casino were instrumental in the decision to prosecute team members on cheating charges. However, the judge ruled that the players' conduct was not cheating, but merely the use of intelligent strategy.

Automatic shuffling machines ASMs or batch shufflers , that randomly shuffle decks, interfere with the shuffle tracking variation of card counting by hiding the shuffle. Continuous shuffling machines CSMs , that partially shuffle used cards back into the "shoe" after every hand, interfere with card counting.

CSMs result in very shallow penetration number of seen cards greatly reducing the effectiveness of card counting. From Wikipedia, the free encyclopedia.

Glossary of blackjack terms Card counting Shuffle track Hole carding. When the deck is still rich in aces, you have a better chance of being dealt a blackjack, so you should increase your bets correspondingly. If everything on the page above seems like gibberish to you, then read through the short glossary below and give it another try.

Balanced vs. Unbalanced — In a balanced card counting strategy, the positive and negative values balance out. This means that a running count through a single deck will result in a total of 0 if you correctly counted the cards. Most systems are balanced, but some unbalanced systems exist.

The goal of most unbalanced systems is to eliminate the need to convert the running count into a true count, but they do so by sacrificing a certain amount of accuracy. Betting Correlation — The betting correlation is a measure of how well a card counting system reflects the advantage or disadvantage to the player. The higher the betting correlation, the more accurate the system.

Levels — Card counting systems are categorized into multi-level and single-level systems. Some systems have even more values. Running Count vs. Most systems require that the counter convert the running count into a true count. This is done by dividing the count by the estimated number of decks still in the shoe. Since a deck that has lots of high cards in it is favorable to the player, a skilled card counter can raise his bets when that situation comes up and actually play a casino game where he has the advantage over the casino.

Snyder recommends that Red Seven Count users memorize basic strategy, and he is correct. In other words, they never both learning how to change their decisions based on the count. The advantage that the Red Seven Count has over other systems is that it eliminates the need to convert the running count into a true count. Many players have trouble with this aspect of counting, so the Red Seven Count eliminates it entirely.

In any card counting system, a heuristic strategy is used to keep up with the ratio of high cards to low cards in the deck. All you have to do is add 1 and subtract 1. In this particular system, aces and tens are worth Every time you see an ace or a seven, you subtract 1 from your running total. That makes this an unbalanced count, which is unusual—most systems are balanced. It varies based on how many decks are in play, but your use of the pivot along with the unbalanced nature of the card counting system make it unnecessary to convert the running count into a true count.

The idea is to raise the size of your bet based on the count. In this system, if the running count is negative, you only bet one unit. If the count is 0, you bet two units. Insurance is the first and easiest decision to make. Any time you have a running count of 0 or higher, you should stand instead. You should also stand on a 12 versus a dealer 2 and stand on a 15 versus a dealer Snyder also recommends a few other counting systems in his books.

He also presents a more advanced version of his Red Seven Count in his books. Zen is a school of Buddhism. Card counting systems enable advantage players to estimate the proportion of high cards to low cards in a blackjack deck. This, in turn, enables them to raise and lower their bets based on this ratio. When a blackjack deck has a high ratio of high cards to low cards, the player has an advantage, and vice versa. Card counting systems assign values to the cards.

When this running count gets high enough, counters raise their bets to take advantage of those better odds. Most card counting systems have an equal number of high values and low values. Since there are four of each card, the final count once all the cards are dealt will be 0. Balanced, single-level systems are the easiest card counting systems to use, but they sacrifice a certain amount of accuracy in exchange for ease of use.

This is a decimal or a percentage. You divide the running count by the number of decks in the shoe in order to obtain the true count. This is the number which determines how much of an edge you have over the casino. Of course, this edge is going to go up and down as you play, but your overall goal is to have an advantage net of between 0.

Only dedicated experts focus on strategy adjustments on top of betting adjustments. The guidelines in Blackbelt in Blackjack suggest that you bet as many units as your count, with a minimum bet of one unit. And so on. You can do this by pretending to be drunk, pretending to not be paying attention, or by pretending to be a novice. Many of the principles involved in card counting in general are well-illustrated by this system.

That kind of savant-style behavior looks great in movies like Rain Man , but in reality, counting cards is much simpler. Blackjack is unlike other casino games, because it has a memory. When you spin a roulette wheel, the odds of landing on a specific number are 37 to 1 every time. But suppose you had a roulette wheel where a specific number was removed after being landed on? Your odds of hitting another number would improve to 36 to 1.

There is no roulette table that works in this way, but blackjack works in a similar way. The only cards which can result in a blackjack natural are the tens and the aces, so you want to bet more when the deck has more of those cards compared to lower cards like deuces or fives. All counting systems track this ratio by assigning a heuristic value to each card type and then keeping an ongoing count of that total.

More complicated systems use different values for different cards, usually between 1 and 3, either positive or negative. The Wong Halves System is different because it uses fractions. The following values are used in the Wong Halves System:.

Of course, everything is relative. Almost all card counting systems, including the Wong Halves Count, requires a conversion from the running count to the true count. The running count is the raw number that you come up with while you keep count of the card values in your head. Converting the running count to a true count compensates for the dilution effect of having so many cards in the deck.

Either way, the main goal of the card counter is to bet more when the count is high. By ranging their bets in this way, users of the Wong Halves Count put more money into action when they have an edge over the casino. This page explains both of those ideas along with what a player needs to know in order to use the Zen Count to get an edge over the house in the casinos. All card counting systems, including the Zen Count, gain an advantage for a player via two methods:.

To get the full benefit from any system, though, memorizing a few tactical deviations in certain situations is necessary. So the first thing that an aspiring card counter needs to learn is basic strategy. Luckily, blackjack basic strategy is relatively simple to learn. Most people can memorize all the rules via a chart in a couple of hours at most.

The reasoning behind card counting works like this—a deck of cards with a lot of tens and aces in it as compared to lower cards is more favorable toward the player. Blackjack players get paid 3 units to 2 for a natural, and you can only be dealt a natural if there are tens and aces in the deck. You just use a point system to keep up with the ratio. The only difference between most card counting methods is how much you add or subtract for certain numbers. The Red Seven count is an unbalanced system, but the Zen count is a balanced system.

In a single level counting system, you only add or subtract 1, based on which card you see. In a multi level counting system like the Zen Count, the amount you add or subtract depends on the rank of the card you see. The values assigned to the cards are listed below, from smallest to highest, in order of rank:. They provide similar betting correlations, in fact, but the Zen Count provides a better estimate of changes to basic strategy, especially as it relates to whether or not to take insurance.

Betting correlation BC is an estimate of how accurate the count is in terms of sizing your bets. Playing efficiency PE is an estimate of how accurately the count adjusts for deviations from basic strategy. The insurance correlation IC estimates how well the system estimates decisions regarding insurance. The Hi-Lo count has an IC of 0. Since playing strategy changes are more important in single deck and two deck games, the Zen Count is especially effective in those types of games.

The first step in deciding how to size your bets using the Zen Count System is to convert the running count into a true count. This conversion takes into account how many decks are in play. You divide your running count by the number of decks in the shoe to determine the true count. Then you size your best based on the true count. You wager only a single unit if the true count is 1 or less. For every point beyond that, you bet an amount equal to the true count.

Everything to know about Blackjack Card Counting. Written By: Staff. Blackjack Card Counting Guide Most casino players think of card counting as an esoteric skill requiring feats of superhuman memory and computer-like mathematical prowess. Card Counting Systems Card counting systems in blackjack are a means of advantage play in which you gauge how favorable or unfavorable the deck is, and then betting more or less based on that estimate. How Card Counting Works You can skip this section if you already understand the basics of counting cards, but if not, this is how it works in a nutshell.

Different card counting methods apply different values to the cards. Raising and Lowering Your Bets and Making Strategy Adjustments As with other counting systems, you raise your bets when the count increases, and you lower your bet when the count is low.

Converting the Running Count to the True Count One aspect of the Hi Opt I system is that it requires a conversion from the running count to the true count in order to remain accurate. You have to take into account how many decks are in use. What about Strategy Decisions? Counting Aces on the Side Unlike in some of the other, easier card counting systems, aces have a value of 0 in the running count using Omega 2. Some Definitions and How They Apply to the Omega II Card Counting System If everything on the page above seems like gibberish to you, then read through the short glossary below and give it another try.

The Card Values In any card counting system, a heuristic strategy is used to keep up with the ratio of high cards to low cards in the deck. How to Bet The idea is to raise the size of your bet based on the count. Tens are worth All other cards are worth 0.

On the opposite end of the spectrum you would subtract 1 from your running count if you see a ten or an ace hit the felt. The other cards you ignore. Each system has different tags and true count resolution methods or lack thereof. Betting Correlation BC : The betting correlation is how effective the card counting system is at predicting valuable betting situations as compared to what a computer could do. The higher the better. Playing Efficiency PE : The Playing Efficiency is a measure of how effective each strategy is at determining correct playing variations i.

Just like betting correlation, the higher the better. Insurance Correlation IC : How effective the card counting strategy is at predicting when to buy insurance. Obviously, strategies that have a separate Ace side count are going to be better at determining when to buy insurance. But in our humble opinion, a side count strategy is not worth the effort.

Putting more time into playing more efficiently, erasing mistakes from your game, and acting less like a robotic card counter will have a bigger impact on your bottom line than learning a more complicated strategy. Balanced or Unbalanced bal? While these systems are fairly simple to explain and understand, much more is required to implement them successfully inside the casino environment and make a profit.

We recommend considering a premium membership to learn everything you need to know to become a successful card counter and not lose your shirt trying to implement something you read about over the last 5 minutes. It sounds scary but go with us here. Once a card is played in a conventional game of blackjack, it cannot be played again until the completion of the whole deck or shoe.

That means the next card to be drawn cannot be the one that was just played. When the cards left to be played are favorable to the player, a card counter can place bigger bets to capitalize on this. Most roulette wheels in the US have 38 possible numbers. The ball MUST land in one of those 38 spaces no matter what.

Each space has an equal probability of winning, each round you spin. The numbers that have recently won have no bearing on the probability of the next number coming up despite the fervent beliefs of many gamblers. The odds are the same this round as they will be the next round. Unfortunately, the majority of things you can wager on in a casino follow the rules of unconditional probability and are generally invulnerable to advantaged play.

It takes many hours of disciplined practice to beat the casinos at their own game. Edward O. On your second spin, that same wager on black has the same number of potential winning outcome: In blackjack, though, the cards that have been dealt change the number of potential outcomes. As a general rule, a deck with a lot of high cards tens and aces left in it is better for the player, while a deck with a lot of low cards twos, threes, fours, fives, and sixes is better for the dealer.

When the deck is rich in high cards, the player has a better chance of being dealt a natural, which pays out at 3 to 2. Some of the advantage from counting cards is had from making some simple basic strategy changes. When the deck is rich in lower ranked cards, the dealer is less likely to bust, making it harder for the player to win that way. The 3 to 2 payout for a blackjack is where the counter gets most of his edge. Most counters range their bets from 1 to 5 units based on how favorable the count is, but some even range their bets from 1 to 10 units.

You can see examples of camouflage in action in the movie 21 , which shows one way in which a team takes advantage of a hot deck. Card counting uses a heuristic method of tracking the ratio of high cards to low cards. The Hi-Lo system is one of the most common ways of doing this. It assigns the following values to the following cards:. You start your count at 0, and then as each card is dealt, you adjust the account by either adding 1 or subtracting 1.

In order to calculate the true count, you first estimate how many decks are still left in the shoe the device which holds the cards for the blackjack dealer. Then you divide the running count by the number of decks left. The higher the count, the more you bet. In the short run, anything can happen, and even card counters with large bankrolls can go broke quickly if luck turns against them. Besides short term fluctuations in the mathematics of the game, casinos will often refuse to let you play blackjack.

Other card counting strategies offer varying degrees of complexity in exchange for varying degrees of accuracy. Most players look for a balance of practicality and play-ability when choosing a system. Other pages on our site look at the specifics of these other counting techniques. You can skip this section if you already understand the basics of counting cards, but if not, this is how it works in a nutshell. Card counting enables players to estimate their relative advantage or disadvantage by keeping a running tally of high cards versus low cards.

Just keep in mind that you have to keep up with this math at an almost lightening-pace in a loud, distracting environment. This is a traditional single level, balanced counting system. All other cards count as 0 for purposes of keeping up with the count. You should practice your counting skills at home before trying this in a casino.

As with other counting systems, you raise your bets when the count increases, and you lower your bet when the count is low. This is where the bulk of your edge from a card counting system comes from. The count can also affect your strategy decisions, such as whether to hit, whether or not to double down, and whether or not to take insurance.

You can get an edge over the casino by just sticking with basic strategy and raising and lowering your bets based on the count, but you increase your edge by making the appropriate strategy adjustments. One aspect of the Hi Opt I system is that it requires a conversion from the running count to the true count in order to remain accurate. The reason for this should be obvious, but a simple illustration should clarify the concept. To adjust for that, you divide the running count by the number of decks you estimate are still left in the shoe.

One way to disguise your skill level is to occasionally make basic strategy mistakes. Which hands do you play incorrectly, though? Only once in a while should you play incorrectly, but that should always be when you have a lower amount of money on the line. The Hi Opt I provides an excellent balance between being easy to learn and effective at the tables. The KO Count is one of my favorite blackjack card counting systems. The KO Count works in a similar manner to all other card counting systems.

Instead, it uses a heuristic system to estimate the proportion of high cards to low cards left in the deck. One hand in blackjack results in a higher payout than any other hand. Only 2 values of cards can combine to form such a hand. One of those is the ace, and the other is then cards with a value of If you removed all of the aces from the deck, your chances of getting dealt a natural would become 0, right?

And when you ARE dealt a natural, you get paid off at 3 to 2. All the aces and 10s count as In most card counting systems, a player has to convert the running count into a true count in order to adjust for the additional decks in play. The effect of each individual card is diluted by the large number of decks in the shoe. The conversion from the running count to the true count requires some division and some estimating. The formula is simple enough—you just divide the count by the number of decks you estimate are left in the shoe.

In the KO system, you can skip the division. Your starting count in the KO system is determined by the number of decks in the shoe. With 6 decks, you start your count at , and with 8 decks, you start your count at A common betting spread is 1 to 5 units. The Knockout Blackjack system was designed to be easy to use and effective at the same time. So the Knockout System is ideal for novices and beginners, but experts who want to take it to the next level will probably want to start experimenting with some of the more involved systems like the Omega II or the Hi Opt I counts.

The Omega 2 or Omega II card counting system is a relatively advanced blackjack card counting system created by Bryce Carlson that was more popular in the s than it is now. Like most of the more advanced card counting systems, the Omega 2 is a multi-level system. Some cards are worth 2 points, while others are worth 1.

The betting correlation is 0. The trick is being able to manage the count. These values should make intuitive sense. And everyone knows that the 4s, 5s, and 6s are the worst cards in the deck for the casino. If you made no other change to a deck than to remove all of the 5s, you would change the game of blackjack from a negative expectation game for the player to a positive expectation game.

He claims that Lawrence Revere would filch 5s from the deck and throw them away in some of the underground cards games in which they used to play. Like other card counting systems, you want to use these values to keep a running count, which, when converted to the true count, will serve as an estimation of how favorable the deck is to the player.

The higher the positive count is, the more you bet. Unlike in some of the other, easier card counting systems, aces have a value of 0 in the running count using Omega 2. But Carlson recommends keeping a separate count of how many aces are still in play. When the deck is still rich in aces, you have a better chance of being dealt a blackjack, so you should increase your bets correspondingly.

Mathematically, the effect of removing the first card from a deck is shown in the table below. For the next card, the same values would be applied, but would need to be multiplied by 1. Instead, there are a number of card counting systems that use whole numbers that remain constant throughout the counting process to provide an estimation of the advantage.

The accuracy of their estimation often comes at the cost of increased complexity, hence difficulty to learn and implement. Here are some of the more popular card counting systems. To give credit where credit is due, this system was developed by Stanford Wong, a prolific author who has authored volumes on almost every casino game. Arguably, this is closer to the actual mathematical weight of the cards, as the seven and nine are not completely neutral—but at the same time, the effect of either is less than a third of a percent.

Legendary blackjack professional Ken Uston pioneered this system, which is largely identical to the high-low count, except that deuces are treated as neutral and sevens as dealer-favourable. Weighed against the mathematical impact of the cards, both assumptions are mistakes, but they more or less cancel each other.

But in our humble opinion, a side count strategy is not worth the effort. Putting more time into playing more efficiently, erasing mistakes from your game, and acting less like a robotic card counter will have a bigger impact on your bottom line than learning a more complicated strategy. Balanced or Unbalanced bal? While these systems are fairly simple to explain and understand, much more is required to implement them successfully inside the casino environment and make a profit.

We recommend considering a premium membership to learn everything you need to know to become a successful card counter and not lose your shirt trying to implement something you read about over the last 5 minutes. It sounds scary but go with us here. Once a card is played in a conventional game of blackjack, it cannot be played again until the completion of the whole deck or shoe.

That means the next card to be drawn cannot be the one that was just played. When the cards left to be played are favorable to the player, a card counter can place bigger bets to capitalize on this. Most roulette wheels in the US have 38 possible numbers. The ball MUST land in one of those 38 spaces no matter what. Each space has an equal probability of winning, each round you spin.

The numbers that have recently won have no bearing on the probability of the next number coming up despite the fervent beliefs of many gamblers. The odds are the same this round as they will be the next round. Unfortunately, the majority of things you can wager on in a casino follow the rules of unconditional probability and are generally invulnerable to advantaged play.

It takes many hours of disciplined practice to beat the casinos at their own game. Edward O. Thorp , wrote a simple math program that could simulate a game of blackjack. He was looking for an optimum strategy that would give a player the best decision for any given hand of blackjack. The strategy he discovered later became known as basic strategy.

He discovered in his simulations that when the remaining cards in the game were rich in tens and aces, the player had a tendency to win more often than the dealer, and when the remaining cards were rich in low cards the dealer would win more often than the player. There are several mathematical explanations as to why this occurs so we made a video about all the reasons. Without getting too deep in the details, a couple of the big reasons are A when there are high cards left in the shoe, the player will get more blackjacks which pay 3 to 2 1.

Thorpe published these discoveries, along with a simple system to use these principles against the casinos, in his iconic work Beat the Dealer in Almost overnight, a revolution was born. The game of blackjack, which was a relatively obscure and unpopular game at the time, became the most popular casino game in America.
