UK PARLIAMENT VOTE ON EU REFERENDUM BETTING

The most obvious of these is providing free "comped" alcohol to anyone who is gambling, which is standard practice in casinos in tourism-dependent areas like Las Vegas a. Addiction, and the unreasonable expectations that drive it, are the basis for the old gambler's saying that losing a lot of money is the second-worst thing that can happen to a new gambler and the worst thing that can happen to a new gambler is winning a lot of money. Research also demonstrates how the brain can get addicted to gambling.

A number of purported methods exist for beating the odds in games of chance, such as slot machines and the lottery. One of these is the use of computer programs in which one enters recent winning lottery numbers, and the program attempts to select the most likely next winning combination of numbers.

This is patent nonsense and a massive misunderstanding of probability , since winning lottery numbers are selected entirely independently and at random. Anyone who thinks a combination of numbers is more likely to be selected because it hasn't been selected before needs a basic class in statistics. Some systems claim they select lottery numbers that are less likely to be picked by other people, so that the expected win will be higher. However, although these systems decrease the chance that a winning bettor will be compelled to share the pot with others, this is the only way in which they increase payout; in particular, they do not in any way increase the odds of that bettor holding winning numbers.

From time to time, some lotteries have an abnormally large jackpot for instance, if it's not won, the prize "rolls over" to be included in the following week , where purchasing a lottery ticket would technically have a better payoff than not purchasing one. However, this only applies to short term lottery play; if you attempt to perform the same trick over the long term, the growth is only positive if you are already a millionaire. Also, it's important to point out that all of this is true only if a lottery or other bet is considered solely as an investment, with only monetary rewards considered.

In other words, gambling is an extremely poor investment strategy, but a person who approaches gambling as something other than an income stream e. Slot machines are a more complicated matter since they use algorithms generating pseudo-random numbers and theoretically this combination must eventually repeat since they are not truly random. However, properly constructed slot machines are designed to defeat attempts at discovering this sequence by constantly generating pseudo-random numbers even when the machine is not being played or in the case of older mechanical ones, have another form of avoiding predictable patterns.

With card counting, it is possible to beat the odds in some card games such as Blackjack. However, some casinos have taken countermeasures to make this tactic more difficult usually by just adding more decks into the shoe and by not dealing all the cards and thus ensure that the house always wins over the long run. The players that are capable of resisting even these tactics will be threatened, and later barred from the casino franchises, or at least from the blackjack tables.

There are also some card games, notably the most popular version of baccarat which is not the one described in the Ian Fleming book Casino Royale , where card counting is completely useless because they are pretty much entirely games of chance. Despite this having been known, in the case of baccarat, for a long time, it hasn't stopped people from trying. The Martingale System is a betting strategy that works only statistically doesn't work, even if you happen to be richer than Bill Gates.

It works thus: In a game of chance, you put up your original stake to bet. If you lose, you double your bet. If you lose again, you double your bet again. Because you have to win at some point, you just keep doubling your bet every time and eventually, you will make all the money back plus the original stake. Obviously, this system requires very large sums of money readily at hand, which the house is always happy to relieve you of.

However, as the per-bet chance of winning decreases linearly, the required reserves increase geometrically. This system therefore is a fine real world example of the sunk cost fallacy. Over the long term, a cursory understanding of probability tells us that any finitely long streak of losses is guaranteed to occur eventually, giving the martingale a probability of ruin equal to one.

This remains the case for any betting scheme that sizes bets independently of the expected value on the bet card counting, noted above, tracks this expected value and wins because it sizes bets accordingly. Speaking of the real world, this principle led the currency trader Nick Leeson to repeatedly redouble losing bets on East Asian currencies, until his losing position reached over 9 billion British pounds.

In so doing, he bankrupted his employer, the major British bank Barings. If the intent is to rapidly amass money by winning bets, the Martingale system falls on its face. If the intent is to amass money gradually by making many small safe bets, there are surely much more profitable avenues to pursue, like the "short stacking" poker strategy outlined below.

Poker is a unique gambling game because instead of playing against the house, you compete against other players. Although luck plays a part in the short term, in the long term skill, table selection and strategy determine a player's average win or loss rate. All players can benefit from learning the basic strategies and by becoming proficient in working out the odds of hands being made in comparison with the size of the pot.

Instead, card counters assign a point score to each card they see that estimates the value of that card, and then they track the sum of these values — a process called keeping a "running count. Basic card counting assigns a positive, negative, or zero value to each card value available. When a card of that value is dealt with, the count is adjusted by that card's counting value. Low cards increase the count as they increase the percentage of high cards in the remaining set of cards, while high cards decrease it for the opposite reason.

For instance, the Hi-Lo system subtracts one for each dealt 10, Jack, Queen, King, or Ace, and adds one for any value 2—6. Values 7—9 are assigned a value of zero and therefore do not affect the count. The goal of a card counting system is to assign point values that roughly correlate to a card's Effect of Removal EOR. The EOR is the estimated effect of removing a given card from play, and the resulting impact on the house advantage. The player may gauge the effect of removal for all cards dealt, and assess the current house advantage of a game based on the remaining cards.

As larger ratios between point values are used to create a better correlation to actual EOR with the goal of increasing the efficiency of a system, such systems use more different numbers and are broken into classes depending on such as level 1, level 2, level 3, and so on, with regard to the ratio between the highest and lowest assigned point values. The High-Low system is considered a level-one count because the running count never increases or decreases by more than a single, predetermined value.

Advanced players might additionally maintain a side count separate count of specific cards, such as a side count Aces, to deal with situations where the best count for betting accuracy differs from the best count for playing accuracy. The disadvantage of higher-level counts is that keeping track of more information may detract from the ability to play quickly and accurately. Some card counters might earn more money by playing a simple count quickly—more hands per hour played—than by playing a complex count slowly.

The following table illustrates a few ranking systems for card counting. Many others exist. The primary goal of a card counting system is to assign point values to each card that roughly correlate to the card's "effect of removal" or EOR that is, the effect a single card has on the house advantage once removed from play , thus enabling the player to gauge the house advantage based on the composition of cards still to be dealt.

Larger ratios between point values can better correlate to actual EOR, but add complexity to the system. Counting systems may be referred to as "level 1", "level 2", etc. The ideal system is a system that is usable by the player and offers the highest average dollar return per period of time when dealt at a fixed rate.

With this in mind, systems aim to achieve a balance of efficiency in three categories: [9]. Some strategies count the ace ace-reckoned strategies and some do not ace-neutral strategies. Including aces in the count improves betting correlation since the ace is the most valuable card in the deck for betting purposes. However, since the ace can either be counted as one or eleven, including an ace in the count decreases the accuracy of playing efficiency.

Since PE is more important in single- and double-deck games, and BC is more important in shoe games, counting the ace is more important in shoe games. One way to deal with such tradeoffs is to ignore the ace to yield higher PE while keeping a side count which is used to detect an additional change in EV which the player will use to detect additional betting opportunities that ordinarily would not be indicated by the primary card counting system.

The most common side counted card is the ace since it is the most important card in terms of achieving a balance of BC and PE. Since there is the potential to create an overtaxing demand on the human mind while using a card counting system another important design consideration is the ease of use. The Running count is the running total of each card's assigned value.

When using a Balanced count such as the Hi-Lo system , the Running count is converted into a "True count," which takes into consideration the number of decks used. With Hi-Lo, the True count is essentially the Running count divided by the number of decks that have not yet been dealt; this can be calculated by division or approximated with an average card count per round times the number of rounds dealt.

However, many variations of the True count calculation exist. Back-counting, also known as "Wonging," consists of standing behind a blackjack table that other players are playing on, and counting the cards as they are dealt with. Stanford Wong first proposed the idea of back-counting, and the term "Wong" comes from his pen name. The player will enter or "Wong in" to the game when the count reaches a point at which the player has an advantage.

The player may then raise their bets as their advantage increases, or lower their bets as their advantage goes down. Some back-counters prefer to flat-bet, and only bet the same amount once they have entered the game. Some players will stay at the table until the game is shuffled, or they may "Wong out" or leave when the count reaches a level at which they no longer have an advantage.

Back-counting is generally done on shoe games, of 4, 6, or 8 decks, although it can be done on pitch games of 1 or 2 decks. The reason for this is that the count is more stable in a shoe game, so a player will be less likely to sit down for one or two hands and then have to get up. In addition, many casinos do not allow "mid-shoe entry" in single or double deck games which makes Wonging impossible.

Another reason is that many casinos exhibit more effort to thwart card counters on their pitch games than on their shoe games, as a counter has a smaller advantage on an average shoe game than in a pitch game. Back-counting is different from traditional card-counting, in that the player does not play every hand they see.

This offers several advantages. For one, the player does not play hands at which they do not have a statistical advantage. This increases the total advantage of the player. Another advantage is that the player does not have to change their bet size as much, or at all if they choose. Large variations in bet size are one way that casinos detect card counters, and this is eliminated with back-counting. There are several disadvantages to back-counting. One is that the player frequently does not stay at the table long enough to earn comps from the casino.

Another disadvantage is that some players may become irritated with players who enter in the middle of a game, and superstitiously believe that this interrupts the "flow" of the cards. Their resentment may not merely be superstition, though, as this practice will negatively impact the other players at the table, because with one fewer player at the table when the card composition becomes unfavorable, the other players will play through more hands under those conditions as they will use up fewer cards per hand, and similarly, they will play fewer hands in the rest of the card shoe if the advantage player slips in during the middle of the shoe when the cards become favorable because, with one more player, more of those favorable cards will be used up per hand.

This negatively impacts the other players, whether they are counting cards or not. Lastly, a player who hops in and out of games may attract unwanted attention from casino personnel and may be detected as a card-counter. While a single player can maintain their own advantage with back-counting, card counting is most often used by teams of players to maximize their advantage.

In such a team, some players called "spotters" will sit at a table and play the game at the table minimum, while keeping a count basically doing the back "counting". When the count is significantly high, the spotter will discreetly signal another player, known as a "big player," that the count is high the table is "hot".

The big player will then "Wong in" and wager vastly higher sums up to the table maximum while the count is high. When the count "cools off" or the shoe is shuffled resetting the count , the big player will "Wong out" and look for other counters who are signaling a high count. This was the system used by the MIT Blackjack Team , whose story was in turn the inspiration for the Canadian movie The Last Casino which was later re-made into the Hollywood version The main advantage of group play is that the team can count several tables while a single back-counting player can usually only track one table.

This allows big players to move from table to table, maintaining the high-count advantage without being out of action very long. It also allows redundancy while the big player is seated as both the counter and big player can keep the count as in the movie 21 , the spotter can communicate the count to the big player discreetly as they sit down. The disadvantages include requiring multiple spotters who can keep an accurate count, splitting the "take" among all members of the team, requiring spotters to play a table regardless of the count using only basic strategy, these players will lose money long-term , and requiring signals, which can alert pit bosses.

A simple variation removes the loss of having spotters play; the spotters simply watch the table instead of playing and signal big players to Wong in and out as normal. The disadvantages of this variation are reduced ability of the spotter and big player to communicate, reduced comps as the spotters are not sitting down, and vastly increased suspicion, as blackjack is not generally considered a spectator sport in casinos except among those actually playing unlike craps , roulette and wheels of fortune which have larger displays and so tend to attract more spectators.

A mathematical principle called the Kelly criterion indicates that bet increases should be proportional to the player advantage. In practice, this means that the higher the count, the more a player should bet on each hand in order to take advantage of the player's edge. Using this principle, a card counter may elect to vary their bet size in proportion to the advantage dictated by a count creating what is called a "Bet ramp" according to the principles of the Kelly criterion.

A bet ramp is a betting plan with a specific bet size tied to each true count value in such a way that the player is betting proportionally to the player advantage with aim to maximize overall bankroll growth. Taken to its ultimate conclusion, the Kelly criterion would demand that a player not bet anything at all when the deck does not offer a positive expectation; the "Wonging" strategy described above implements this.

Historically, blackjack played with a perfect basic strategy offered a house edge of less than 0. Advantages of up to 2. The variance in blackjack is high, so generating a sizable profit can take hundreds of hours of play. Under one set of circumstances, a player with a unit bet spread with only one-deck cut off of a six-deck game will enjoy an advantage of as much as 1.

Instead, it comes from the increased probability of blackjacks, increased gain and benefits from doubling, splitting, and surrender, and the insurance side bet, which becomes profitable at high counts. A range of card counting devices are available but are deemed to be illegal in most U. 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 a win on any given spin, the gambler will net 1 unit over the total amount wagered to that point. Once this win is achieved, the gambler restarts the system with a 1 unit bet. With losses on all of the first six spins, the gambler loses a total of 63 units. This exhausts the bankroll and the martingale cannot be continued. Thus, the total expected value for each application of the betting system is 0. In a unique circumstance, this strategy can make sense. Suppose the gambler possesses exactly 63 units but desperately needs a total of Eventually he either goes bust or reaches his target.

This strategy gives him a probability of The previous analysis calculates expected value , but we can ask another question: what is the chance that one can play a casino game using the martingale strategy, and avoid the losing streak long enough to double one's bankroll. Many gamblers believe that the chances of losing 6 in a row are remote, and that with a patient adherence to the strategy they will slowly increase their bankroll.

In reality, the odds of a streak of 6 losses in a row are much higher than many people intuitively believe. Psychological studies have shown that since people know that the odds of losing 6 times in a row out of 6 plays are low, they incorrectly assume that in a longer string of plays the odds are also very low.

When people are asked to invent data representing coin tosses, they often do not add streaks of more than 5 because they believe that these streaks are very unlikely. In a classic martingale betting style, gamblers increase bets after each loss in hopes that an eventual win will recover all previous losses.

The anti-martingale approach, also known as the reverse martingale, instead increases bets after wins, while reducing them after a loss. The perception is that the gambler will benefit from a winning streak or a "hot hand", while reducing losses while "cold" or otherwise having a losing streak. As the single bets are independent from each other and from the gambler's expectations , the concept of winning "streaks" is merely an example of gambler's fallacy , and the anti-martingale strategy fails to make any money.

If on the other hand, real-life stock returns are serially correlated for instance due to economic cycles and delayed reaction to news of larger market participants , "streaks" of wins or losses do happen more often and are longer than those under a purely random process, the anti-martingale strategy could theoretically apply and can be used in trading systems as trend-following or "doubling up".

In some countries — notably the UK, Ireland, and Australia — an alternative and more popular facility is provided by bookmakers who effectively make a market in odds. This allows the gambler to 'lock in' odds on a horse at a particular time known as 'taking the price' in the UK. In North American racing, the three most common ways to bet money are to win , to place , and to show. A bet to win , sometimes called a "straight" bet, means staking money on the horse, and if it comes in first place, the bet is a winner.

In a bet to place , you are betting on your horse to finish either first or second. A bet to show wins if the horse finishes first, second or third. Since it is much easier to select a horse to finish first, second, or third than it is to select a horse just for first, the show payoffs will be much lower on average than win payoffs. If there are a small number of horses in the race, show or place bets may not be offered or if bets have already been made, they are cancelled and the wagered amounts refunded.

In Europe, Australia, and Asia, betting to place is different since the number of "payout places" varies depending on the size of the field that takes part in the race. For example, in a race with seven or less runners in the UK, only the first two finishers would be considered winning bets with most bookmakers. Three places are paid for eight or more runners, whilst a handicap race with 16 runners or more will see the first four places being classed as "placed".

A show bet in the North American sense does not exist in these locations. An each-way bet sees the total bet being split in two, with half being placed on the win, and half on the place. The full odds are paid if the horse wins, plus the place portion , with a quarter or a fifth of the odds depending on the race-type and the number of runners if only the place section of the bet is successful. In the UK some bookmakers will pay for the first five some independent firms have even paid the first six for a place on the Grand National.

This additional concession is offered because of the large number of runners in the race maximum Occasionally other handicap races with large fields numbers of runners receive the same treatment from various bookmakers, especially if they are sponsoring the race. Each portion is treated by the totalizator as a separate bet, so an across-the-board bet is merely a convenience for bettors and parimutuel clerks.

In addition to straight wagers, "exotic" wagers offer bettors an opportunity to incorporate the placement of different horses in one or multiple races. The two broad types of exotic wagers are horizontal and vertical. Horizontal exotic wagers are bets on multiple horses in one particular race, while vertical exotic wagers involve predicting results across multiple races. Both have specific options for which bets are available and are detailed below.

In the most basic horizontal wager, an exacta , the bettor selects the first and second place horses in the exact order. Picking the first three finishers in exact order is called a trifecta and a superfecta refers to the specific finishing order of the top four horses. Boxing is a tactic that increases the odds of winning an exotic wager by removing the need to choose the exact order.

A quinella , which boxes an exacta allowing the first two finishers to come in any order and still win , is the basic box, but boxing can be applied to the trifecta and superfecta as well. In a sense, a win bet can be thought of as a specific type of wheel bet. Vertical bets are spread over different races. A daily double is an exotic wager placed on the winner of two consecutive races.

Picking the winner of three, four, five or six straight races is referred to as a pick-3 , pick-4 , pick-5 and pick-6 respectively. In addition to traditional betting with a bookmaker, punters bettors are able to both back and lay money on an online betting exchange. Punters who lay the odds are in effect acting as a bookmaker. The odds of a horse are set by the market conditions of the betting exchange which is dictated to by the activity of the members.

By the late 19th century over tracks were in operation in the country but those opposed to gambling caused the banning of bookmakers and horse racing at the beginning of the next century. In pari-mutuel tote betting was introduced, helping the industry to prosper and that has continued to be the case to the present day. Pari-mutuel betting is currently legal in 32 US states.

Due to new legislation horse race betting in the US could change significantly in the near future.
