Casino movie "21."

A scary movie was released.

I saw a review on the 바카라사이트 Casino Land.

A math genius at the Massachusetts Institute of Technology (MIT) swept a large sum of money at a blackjack table in Las Vegas, the USA, with a technique called 'card counting.'

The movie '21' is an adaptation of a 'true story' from 1994 to 1995. The main character, Ben Kemble (Jim Sturgess), is a math genius recognized at MIT.

He is recognized for his witty answer in Professor Mickey Rosa (Kevin Spacey) 's lecture on nonlinear equations and joins the professor's blackjack team.

And there, he learns to count cards. Blackjack is a game in which the player who adds up the number of trump cards to a number close to 21 wins. A is counted as 1 or 11, and J, Q, and K are counted as 10.

The dealer must receive cards unconditionally if the sum of the cards is less than 17, and the player can decide for himself according to the situation on the table. If you go over 21, you lose unconditionally.

The game is played 1:1 between the dealer (casino side) and the player who divides the hand. Even if there are multiple players at a table, each player only needs to win the dealer.

However, since players are dealt cards first, it is essential to make a hand that is not over 21 but is close to 21. Card counting is a method devised in 1963 by Edward Thorpe, a professor of mathematics at MIT.

Professor Thorpe noted that the higher the number of cards not on the table, the more likely the player was to win. If the dealer's hand is less than 17

He is more likely to go over 21 because he must receive a card unconditionally. Professor Thorpe counts the cards on the table and is much lower.

The higher the number of the remaining cards, the higher the probability of winning was calculated. So, according to his theory, the player has about a 52% chance of winning when the higher numbers are left.

It was a subtle difference, but Professor Thorpe made nearly \$100,000 based on his theory and flattened the nose of the casino. 30 years have passed since then

Card counting methods have become more sophisticated, and MIT professors and students synthesized them to create the most straightforward strategy. Depending on the size of the number without memorizing all the cards

This is a hi-low method, starting from 0 and adding and subtracting numbers. This method was also used in the movie. For example, in the high-low method, 2 to 6 add 1, and 10·J·Q·K·A subtracts 1.

7-9 are not counted. Therefore, if the calculated number exceeds +10, it means that there are many high cards left, and if it is close to 0 or negative, it means that the probability of losing is high.

In particular, MIT professors and students kept counting while playing the game, and when the number fell below 10, they stood up. When depending on all one deck of cards, the number is

It starts from 0 and ends with 0, so even if you participate in the game at a good point, you will inevitably become at a disadvantage over time. Kevin Lewis, then a student at MIT,

In the book 'Breaking Down the Casino of MIT Mathematical Geniuses,' which became the original work of Movie 21, he said, "The method of making 0 by pairing +1 and -1 cards made calculations much faster and more accurate than the existing method."

If so, is card counting still effective ten years after the actual incident? The answer, unfortunately, is 'no.'

This is because casinos restrict the entry of card counters, and a device has been prepared to prevent card counters secretly participating in the game from counting correctly.

Most casinos have machines that allow you to reshuffle the cards used in the game. As a result, dealers can cut down on manual mixing time.

This is because you can quickly shuffle the cards before they run out so as not to interfere with the game's progress. But unfortunately, it is a fatal method for a card counter that predicts the remaining cards by memorizing them in front of them.

Also, some casinos change the rules of blackjack. For example, the dealer must take an extra card for a hand under 17, but some casinos only accept cards under 12.

Even if you receive a high number of cards, the probability of not exceeding 21 increases; there is also a limit on the number of bets placed on a single game.

If you want to win money without getting caught by card counting, you have to bet a little bit when the count is less than +10 and bet a lot when it is over +10.

However, if you limit the maximum bet amount, it won't be easy to regain as much as you lose. As Professor Mickey in the movie told his students

"If the odds of a daughter are low, you should rob her right away and get up," but it's easy to lose her temper once you start gambling.

A team led by Professor Stephen Quartz of the California Institute of Technology used functional magnetic resonance imaging (fMRI) to scan a gambler's brain.

"The expectation of winning money slows down areas of the brain that feel threatened," published in the American journal Neuron in August 2006.

So, among professional gamblers, a famous saying has been passed down for a long time. "The only way to win a casino is not to go to the casino " he said.
