How to beat the casino – legally
If there’s something everyone understands about gambling it’s that this house always wins. And while it is true that casinos always make money, there are a number of ways to cheat it – many of which are actually perfectly legal.
Half a century ago, mathematician Edward Thorp published a groundbreaking book outlining the way a player could use “card counting” to have an advantage amongst gamers Blackjack by maintaining a record of they left in a very deck. Ever since, casinos have been looking to eradicate card counting while card counters are receiving increasingly skilled at failing to get caught. So is it possible to outplay casinos today? And after that or not it's such as the long run?

Casinos are businesses and operate by building inside a margin – often referred to as your home edge. If you play roulette and bet on a single number you may be paid at odds of 35-1 in the event the true likelihood is 36-1 in Europe and 37-1 in the US. The fact that you are experiencing below the actual odds is your home edge and explains why casinos earn money in the long term. Of course, many people need to win, otherwise casinos would disappear.
Advantage players
What casinos don’t like are “advantage players” – people planning to provide an edge over your home. Sometimes this involves cheating and/or illegal activities which range from past posting (setting up a bet following your time when no more bets are to be taken) to collaborating in the chat box and taking advantage of your personal computer to make decisions.
Card counting, however, is legal. In Blackjack, the aim of the player would be to acquire a hand of cards whose points accumulate closer to 21 as opposed to dealer’s hand, but without exceeding 21. Many hands are played from your same deck of cards, just what exactly occurs in one hand will influence what occurs in future hands. As an example, if a ten has become played from the pack then it cannot show up in the subsequent hand. This is not the same as other games, including roulette, in which the upshot of one spin doesn't have relation to the next spin.
Card counting will depend on the belief that a large proportion of high cards (including tens, jacks, queens and kings, that happen to be all worth ten points) left inside unplayed deck statistically improves the player’s chances. This is because a person can decide not to draw a new card to your hand for example 16, however the casino is forced to, mainly because it follows strict rules. If there is a high proportion of high cards left inside unplayed deck, the casino dealer has more probability of busting (going over 21). This can be coupled with “basic strategy” – developed from computer simulations of an incredible number of blackjack hands – which tells the player the best thing to do per possible card combination.
Combining card counting and basic strategy might help a player convert the (long term) house edge from 2.7%, towards the casino, to about a 1% benifit of the player. Of course, when you have this advantage you are able to increase your bet.
To offer a simple example, had you been playing basic strategy and were dealt a ten and a six, and the seller had a three showing (among the dealers cards is visible to the gamer), you'd probably stand (not take another card) because you hope how the dealer would draw a ten and bust. If you were card counting, and you also knew more and more low cards was played, you may decide to enhance your stake at this point.
Evolving battle
Casinos have introduced a number of measures to deter card counting. These include spotting those carrying it out and banning them from playing, and even from entering the casino. Another approach is usually to boost the amount of decks from to (typically) six, or even eight. Some casinos also shuffle the cards only for about 75% happen to be played or shuffle them constantly using automatic shufflers.
You might wonder why casinos don’t simply withdraw blackjack. Well, it remains a favorite game, then one that is still profitable. There are also many would-be card counters that are not actually that good advertising online, plus they provide income to the casinos.
Many blackjack players have fought back against such measures, arguing that casinos should allow gamblers to work with skill when playing the overall game. As a card counter operating independently is relatively an easy task to spot (intense concentration, increasing bets and so on), a team of students from MIT showed it might successfully be accomplished in teams. The idea is the fact that someone else counts the cards – they could not even be sitting at the table. When the count reaches an agreed value, they signal to another player, who joins the table to start betting. This is a many more challenging to detect but casinos may stop players joining the sport until after a shuffle to combat a real strategy.
Other players manipulate shuffle tracking, where blocks of cards are tracked so that you have some idea after they can look. If you happen to be due to the substitute for cut the pack, you try and cut those near in which you think the block of cards you are tracking is so that you'll be able to bet accordingly. A variant for this is always to track aces as, once you learn when you are likely to appear, you've got a distinct advantage on the casino.
It’s been half a century since Thorp’s book, which is unlikely that the war of wills between blackjack players and casinos can certainly in the near future. Some of our work has investigated how artificial neural networks (simple kinds of the human brain) can help you evolve blackjack strategies. This was produced by playing a large number of blackjack hands and also the computer learning how to handle it in a given situation, improving whenever. There is a lot of scope to find out if automated computer programs could learn even more sophisticated strategies.
