"I'm not going to play eighty points today, let's play something else. Pen ~ fun ~ pavilion www.biquge.info" It was nine o'clock in the evening, Xiao Yao took the playing card and said to the three unscrupulous roommates in the dormitory.

After more than 20 days of intensive training, Xiao Yao has basically no hope of entering the Olympiad national team and becoming a regular player. Xiao Yao's mentality is quite calm about this, but he is still unwilling to play cards in the dormitory and be ravaged by three roommates. Eighty points really can't play them, and today Xiao Yao simply changed his tricks.

"You can't play anything against us," Yan Ke smiled arrogantly, "At most, we won a few games in the first few games while we were not familiar with the rules, do you want to change the way we play every day, just to win a few games at the beginning?"

"Cut~" Xiao Yao pursed his lips disdainfully and ignored him.

Chen Jiwei waved his hand at Yan Ke and Yu Gang and said: "Forget it, we've been bullying others for a long time, and people want to change their ways of playing to find some confidence, so let's just settle on him." After speaking, he turned his head and asked Xiao Yao again, "What are you playing today?"

"21 o'clock! will you?" Xiao Yao smiled with the corners of his mouth crooked.

"No!" Chen Jiwei and Yu Gang replied at the same time.

"21 o'clock?" Yan Ke obviously would, but said with some surprise: "It's okay to play cards, but the rules of the training camp are strictly forbidden to gamble." ”

In the two hours of free time from nine o'clock to eleven o'clock, it was not only the four people in Xiao Yao's dormitory who played cards. Teachers are not forbidden to play poker, on the one hand, there is no TV in the dormitory of middle school students, and the students are really bored at night, on the other hand, most of the playing cards are also brain-solving, so it is considered extracurricular training.

But for these teenage children, it is not completely indulgent. The teachers strictly forbade the students to gamble by playing cards. Once discovered, they will be immediately expelled from the winter camp training team.

"It's not gambling if you don't play for money. Xiao Yao explained with a smile, "I prepared melon seeds, green beans, toffee, and chocolate. Each of them has a big bag, and we use these things to represent different points, and everyone will get the same value at the beginning, and finally the winner or loser will be determined by the value of the things they have. ”

"Yes. "The three of them think about it, it's doable. Yu Gang was still a little unwilling to say: "Why do you have to have a little color, right? Why don't you play 80 points like before, and the one who loses is responsible for the hygiene of the dormitory?"

As Yu Gang spoke, the eyes of the three of them all glanced at Xiao Yao. Xiao Yao ignored the expectant looks of the three of them, shook his head and refused: "I've been cleaning for more than ten days." Change the rules today, and if you lose, you will have a meal tomorrow. ”

"It's okay, big stars have money anyway. The three of them jokingly said.

"Don't be complacent, beware that I will eat you poor tomorrow. Xiao Yao said viciously.

"First of all, let's explain the rules that you two don't know. To put it simply, it's all about looking at points. The flower cards JQK are all ten points, and A can do both eleven and a little. The total of 21 is the highest, and if it is exceeded, it will explode, and whoever has the most points will win if it is not higher than 21 points. Bet first, then deal. At the beginning, each person is dealt two cards, the player has two cards, and the banker has one bright and one dark. If you have less than 21 points, you can play again until you burst. Get a plus ten points, that is, two cards constitute 21 points, called blackjack, the dealer pays 1.5 times, of course, the premise is that the dealer does not also get BJ, otherwise it is a draw. If the player's starting two cards have the same number of cards, you can choose to split the cards, one becomes two, and if you meet the same number of points again, you can also choose to divide again, up to one is divided into three, but the extra number of cards after splitting must be made up with the same note. After splitting, each team calculates the win or loss separately, do you understand?" Xiao Yao looked at the two of them.

"Understood!" The two guys who can enter the Olympiad Winter Camp must also have a good IQ, Xiao Yao explained it so clearly, how could he not understand?

"Okay, let's get started. I'll be the banker!" As he spoke, Xiao Yao took out five brand-new decks of playing cards from the table one after another.

"Damn, do you want so many?" the three of them stared at the five decks of cards, their eyes widening.

"The time has come to test your brains. After removing the big and small kings and a redundant matching card, Xiao Yao mixed the five decks of cards together and shuffled them, and said while shuffling the cards, "I know that you play cards by brain, not luck." If you can build a mathematical model or formula to play this to count the cards, increase the probability of winning, and prove that it actually works. In the future, I will take you to Machia or Las Vegas. ”

"Really?" said the three of them excitedly. If others say so, the three of them will definitely be suspicious, but Xiao Yao has the identity of a star, whether it is going to Macheng or the United States, it is really not too difficult for him.

"Don't get too excited. This is not the eighty of two decks of cards, but the main and fractional cards in the hands of others can be counted from the card path and the cards that have been played. Xiao Yao poured cold water on the three of them and said, "These are five decks of cards, and it's hard for you to understand your opponent." The only options you have are to hit and don't. Even if you are all mathematical geniuses, it is not easy for you to come up with such a mathematical model or formula. If you don't have a way to improve your chances of winning, I won't take you there. ”

"What the hell do you want to do?" The more the three of them listened to Xiao Yao's words, the more confused they felt.

"I want to play big. Xiao Yao smiled: "I want to capture the casino." ”

"How did you attack?" the three of them said in surprise: "By 21 o'clock?!"

"Rely on math!" The way is through 21 points!" Xiao Yao pointed to his temple, "Of all the items in the casino, except for slot machines, the smallest human factor is 21 points." Each table is five decks of cards, and they are shuffled through the shuffle, the dealer is also trained in the same way, and there is a rule of what to do and what not to do. I think it's entirely possible to rely on math to improve your odds of winning money at 21. ”

"How do you know so well?" Yan Ke asked curiously, "Have you ever been to the casino?"

"Nope. Xiao Yao shook his head.

"Then how do you know that you can win money in the casino by relying on math?" Yu Gang also asked.

"I know from the way you abused me so well a few days ago. Xiao Yao smiled bitterly, "Why do I always lose to you when I play eighty points? Is it because my experience is not as good as you? Is it because your memory is not as good as yours? Which of you dares to memorize English words with me? It's not because you're better at math than me, and you're better at counting cards than me. Eighty points can be counted, but 21 points can't be counted?"

"Can I tell you that in my previous life, there was a guy named Ma Kaiwen who did it with his companions?" Xiao Yao added silently in his heart.

Xiao Yao grew up watching films such as Fa Ge's God of Gamblers, Andy's Gambler, and Xing Ye's Gambling Saint when he was a child in his previous life. Although he was fascinated by the various card playing techniques in gambling movies for a while, Xiangjiang's gambling movies seemed too exaggerated, and he never wanted to connect them with real life.

Until 08 years in his previous life, when he was already an adult, he saw an American gambling film called "21 o'clock in the decisive battle". To be honest, the film as a whole is not very good, but he was still impressed by the plot of counting cards to increase the odds of winning and successfully winning a lot of dollars from the casino.

After a little checking, he was surprised to find that this movie was based on a true story. The prototype of the main character, Kevin Ma, is a Chinese-American math genius at the Massachusetts Institute of Technology. Ma Kaiwen and his companions relied on card counting to make about $10 million from the casino in a few years. The United States has not only made movies based on his deeds, but also best-selling books about the deeds of Kevin Ma and his companions adapted into novels. Since then, Ma Kaiwen's name and deeds have also been deeply imprinted in his mind.

Xiao Yao in his previous life was not a mathematical genius, and he could only sigh at the deeds of Ma Kaiwen, a great god. But Xiao Yao in this world is different, although he is not a mathematical genius, but there is no Ma Kaiwen in this world, and no one has used card counting to set off a "bloody storm" in Las Vegas. Xiao Yao wants to get his own 21 o'clock group out and go to the casino to do whatever he wants, it is not completely impossible.

Some time ago, while being ravaged by the three guys in the same dormitory every day, Xiao Yao also found that the three of them seemed to have some talent in using mathematics and cards. As he himself said, whether it is playing experience or memory, he is stronger than the three, such a way to lose, can only be because they are particularly good at counting cards. I didn't expect to participate in a math winter camp, and at the same time, I was shocked to the point and accidentally found three guys who were quite talented in card counting. Xiao Yao's crazy idea buried deep in his memory was a little chilly.

Seeing the tangled expressions of the three people who were a little hesitant and a little excited, Xiao Yao smiled and continued: "Don't be so entangled, I just have such an idea, and I just mentioned it by the way, and I don't want us to do this tomorrow or next year." ”

"U.S. imperialist law requires you to be at least 21 years old to enter a casino, and I'm five years away. Xiao Yao continued, "And the way to improve the odds of winning is not so easy to find, we are all high school students now, and it is not certain whether we can get it out with the current mathematical knowledge." "In his previous life, when Ma Kaiwen joined the 21-point card counting team, he was a top student in the third year of MIT, and now their middle school students are definitely not at his level.

"I mean, you might as well think of this as a long-term goal, when we find an effective way to count cards, when to do it again. A Mr. Ma once said, "Dreams are always there, what if they come true?" Xiao Yao quoted the classic words of Ma Yun in his previous life.

"Which Mr. Ma?" asked Chen Jiwei with a confused expression.

"That's not the point. Xiao Yao waved his hand, "The point is whether we can find an effective method of card counting." Let's not think of this as a gamble, but as a math problem. When we solve it, we want to make it known in a way that shocks the world. ”

"But I guess we'll have to wait until I'm in college. The first is that we are old enough to enter the casino at that time, the second is that it may be until then that the mathematical knowledge we master is enough to support the theoretical basis of our card counting, and the third is that we can also have the kind of personal freedom that can run around at that time. Xiao Yao clapped his hands, and finally concluded, "So, I hope you can have such an idea in your heart now and work hard in this direction." Hopefully, in a few years, we'll be able to do it. ”

"Okay, interesting, do it!" Yu Gang was the first to respond.

"It's just exciting to think about. Chen Jiwei also blushed and said excitedly.

"We just treat him like a math problem, and I don't believe we can't solve it in years. Yan Ke was also convinced.

"Okay, you will be responsible for solving the problem, and I will be responsible for the rest. Xiao Yao nodded with a smile.

Now the world is at the beginning of 2015, and the development of science and technology is far from comparable to the mid-90s of the 20th century in the previous life. All he wants is to live an addiction that he never forgot in his previous life.
