"Talent again?" Sandra looked at Xiao Yao and said, "since you are so talented in mathematics, why don't you study science and become an artist instead?"

"Because I have a higher talent in music and performance!" Xiao Yao didn't blush at all.

"Well, I'm taking a test, not to discuss my life and career choices with you!" Xiao Yao then said, "excuse me, have you finished my test? Did I pass the test? "

Sandra, Taylor, Sam and Raj looked at each other and nodded.

"Can you teach me how to count cards?" Xiao Yao asked.

"Of course!" Tyler nodded, reached out and said, "welcome to the mit21 point group."

"Join?" Xiao Yao said with a smile, "but I'm not a student of MIT!"

"Yes," Tyler said, "you're the first non MIT student in our group."

"Well, my pleasure!" Xiao Yao reaches out and shakes Taylor.

"I'm hungry!" Sam raised his hand and said, "I think we should celebrate that we have new members and find a place to eat!"

"OK, it's my treat!" Xiao Yao said with a smile, "this is your territory. If you look for a place, I'll pay for it!"

Xiao Yao, Yan Ke and others didn't come here very early. It took a lot of time to introduce and exchange greetings, plus two tests. Now it's almost lunch time.

"Since it's our territory..." Taylor said.

"I agree!" Yan Ke interjected, "he is a star, very rich, should let him pay! Let's choose a more expensive place! "

"All right!" Tyler thought about it and nodded.

After discussion, the party left school for lunch.

Although Yan Ke said that he wanted to "eat big", Xiao Yao was finally taken to a small restaurant not far from the school. Judging from the scale and decoration, it doesn't seem to be a particularly high-end place. Xiao Yao's treat to dinner is just polite, not to show off how rich he is, so he didn't raise any objection. He followed everyone into this seemingly ordinary restaurant.

After everyone entered the restaurant to find a vacant seat, the waiter of the restaurant quickly came to greet them and gave them the menu.

After receiving the menu sent by the waiter, Xiao Yao was dumbfounded.

"What kind of menu is this?" Xiao Yao is a little speechless.

The menu of this restaurant is very special. The normal menu includes the name and price of the food. On the menu of this restaurant, the food name is nothing special, but the price position corresponding to the food name is not a number, but a different mathematical formula. Moreover, these formulas are not simple four arithmetic operations or equations, but complex formulas involving advanced mathematics, of which more than 80% are beyond Xiao Yao's comprehension, let alone calculation.

"Ha Seeing Xiao Yao's silent expression, Taylor and others laughed.

"The owner of this restaurant is a teacher in the Mathematics Department of our school!" Sandra explained with a smile, "the customers here are basically our school students! So welcome to MIT! "

this restaurant is not far from MIT. After listening to Sandra, Xiao Yao understood.

"You just said that I have passed the test," Xiao Yao asked Sandra in a low voice, leaning forward. "So, this is not another test for me, is it?"

"It seems that you really haven't studied advanced mathematics!" Sandra understood and said with a smile, "yes, it's not a test."

"Oh Xiao Yao was relieved and leaned back in his chair.

"But," Sandra asked, "you don't understand the menu. How do you order and pay?"

"Cut ~" Xiao Yao said, "I just can't understand the formula of the price. Why can't I understand the menu? I'm a rich man. I don't care about the price when I order. I just need to know the name of the dish. As for the bill, I'll pay as much as the waiter says. I don't care! "

"Eh ~" Sandra turned her lips in disgust.

Taylor and others all know that Xiao Yao is definitely a rich man, but after a morning's contact, they found that Xiao Yao has neither the airs of a star nor the dandy style of a rich man, and they still have a good impression on him. Now Xiao Yao deliberately raises money in response to Sandra's ridicule. In their view, it's witty and humorous, rather than showing off. Instead of disgusting, he feels a little cute.

Xiao Yao doesn't think that all students in schools like MIT are nerds, especially those who want to use mathematics to count cards and use them to win money in casinos. Xiao Yao is also very interested in this group of people, and has a certain favor, and is very friendly.

So, the atmosphere of this meal is very good. After a meal, Taylor and Xiao Yao had a good chat. They got to know each other better and became familiar with each other.

After lunch, we took a short rest and went back to a classroom of MIT to start the teaching of card counting.In the afternoon teaching, Taylor and others took turns. Someone is responsible for explaining the formula and calculation method used in counting cards to Xiao Yao, and someone is responsible for demonstrating.

Xiao Yao's learning ability and efficiency are very good, and do not seek to understand the deep mathematical principles and knowledge involved in the formula, just to master the method, quickly understand and learn the card counting method.

"I think I understand!" Not too long, Xiao Yao said confidently.

The people in the card counting group didn't seem too surprised, and they didn't have any praise. They seemed to have expected the result.

"Is it?" Sam went to Xiao Yao with a bag and took out playing cards and chips from the bag, "let's have a try! This time we'll play with three sets of cards! "

"Good!" Xiao Yao was also eager to try, and nodded happily.

This is different from the memory test in the morning, it is simulated the actual situation of the casino. Taylor is the dealer, Sam, Raji and Sandra are all on the court, just like Xiao Yao. Only Yan Ke does not participate in the game, and just stands by.

Although Sam, Raji and Sandra are on the stage, they just play the ordinary passers-by players in the casino, not with Xiao Yao. In the following process, the three people's bets and cards are very casual, everyone's focus is on Xiao Yao.

Xiao Yao's performance is very good. Through the study just now, Xiao Yao really understood and mastered the card counting method they taught. After more than an hour, the chips in front of Xiao Yao almost doubled.

"It looks like I can leave for Vegas tomorrow!" Xiao Yao looked at the chips in front of him and turned to Yan Ke and said with a smile.

"What? You're going to Vegas tomorrow? " This time, the people in the card counting group were surprised, and Taylor asked.

"Yes Xiao Yao said with a smile, "if I don't go to Vegas, why do I want to learn how to count cards?"

"No," Tyler said, "my point is, are you going alone?"

"Yes Xiao Yao nodded, "I've heard Yan say that when you go to Vegas, all the members of the team will go out, act together, and cooperate with each other. But aren't you all blacklisted by Vegas casinos? I want you to go with me, but Yan said you can't go to the casino, so I can only go alone. "

"Also," Xiao Yao looked at the chips in front of him, and then said, "it seems that one person can operate such things as counting cards."

"Is it?" Taylor laughs. "The casinos don't play with three sets of cards. Let's try some more."

“OK!” Xiao Yao nodded.

He heard that the blackjack tables in casinos usually use five to six sets of cards at a time. The difficulty of three sets of cards is indeed smaller than the actual situation, but Xiao Yao thinks he has learned how to count cards, and does not think that adding a few sets of cards will not win.

"This time we'll use eight Deck Cards!" Tyler takes five more sets of cards from Sam's bag.

"What?" Xiao Yao slightly surprised, "I heard that casinos usually use five to six Deck Cards!"

"Yang, there are eight pairs of cards, too. We've met them in casinos!" Yan Kedao.

"All right!" Xiao Yao nodded.

The difficulty of eight pairs of cards is indeed higher than that of five or six pairs of cards, which is more difficult to calculate. However, Xiao Yao has enough confidence in his memory and mental arithmetic ability. For him who has mastered the card counting method, he is confident that he can cope with the increase of difficulty.

From the third deck to the eighth deck, the difficulty has increased a lot, but Xiao Yao's performance is OK. Basically, the chips are increasing slowly, so Xiao Yao looks calm. But when Taylor raised the difficulty again, Xiao Yao was not calm.

"Again!" After eight pairs of cards, Taylor didn't deal all the cards, but after seven or eight games, he combined the abandoned cards and unused cards again.

The more abandoned cards, the less unused cards, the higher the accuracy of player judgment. However, it's not that you can't play when you start a lot of cards. Xiao Yao thinks that Taylor started all over again just because he didn't show any decline in the previous games, so he just shrugged his shoulders and didn't object.

What Xiao Yao didn't expect was that Taylor didn't start to deal the eight deck cards after he put them together again. Instead, he took off a large stack of cards and put them aside. He just started with the remaining cards.

In this way, the number of points on the table and some special cards can not be estimated.

Xiao Yao immediately frowned and said: "Hey ~"

"this kind of situation will happen in the casino!" Yan Ke is on a side road.

Although Xiao Yao heard that Yan Ke's tone seemed to be a bit of schadenfreude, he didn't ask. He just frowned and nodded, indicating Taylor to continue.

From the card counting method that Xiao Yao learned just now, this kind of situation belongs to some super outline. When Xiao Yao was playing, the speed obviously slowed down, and the time to think about whether or not to play a card obviously became longer.

Although Xiao Yao took longer to think about it, the situation did not get better. After ten games, the chips in front of Xiao Yao are obviously less. Counting cards is to play probability, which is to improve the overall winning probability. The more times you play, the more obvious the effect is. It can't guarantee that every hand can win, so it's normal for chips to become less in a certain period of time. It doesn't necessarily mean that there is something wrong with Xiao Yao's algorithm, but Xiao Yao obviously feels that there is something wrong with him.It's hard for Xiao Yao to cut off a part of the cards at the beginning. Unexpectedly, after playing more than ten games, Taylor opened a new set of unused cards. After shuffling, he added part of them to the pile of cards to be issued.

"Hello Xiao Yao saw Taylor's action and immediately cried out discontentedly.

"Young," Tyler laughs.

"Don't tell me that's what's really going to happen in casinos!" Xiao Yao looks at Taylor.

"It's true Tyler said, "we've really met. As you know, we are not the only people who count cards now. It is not that casinos have never met card counters. Those who do not use the snail licensing machine gambling table found suspected card tellers and can not be determined, will use these additional methods to deal with suspected card tellers

"I'll go, and that kind of thing?" Xiao Yao glared, "so, isn't that no fun?"

"No confidence?" Taylor said with a smile, "are you going to give up?"

"I'm not here to gamble with you!" Xiao Yao said, "what you taught me can't cope with such a situation. If you continue to gamble, it's pure luck. I'm not a gambler. It's meaningless to fight for luck. It's meaningless to continue gambling. "

"Ha ~" all the people in the card counting group laughed.

"Are you kidding me?" Xiao Yao looked at them and said, "well, I admit that I was too arrogant just now. Before you finished teaching, I can't wait to say that I learned it!"

"Why do you say that?" Tyler asked.

"Yan told me that you've been to Vegas and have been blacklisted by the casino alliance." Xiao Yao said, "only if you win money will you be blacklisted by casinos. Yan also said that you really win money from casinos. You have met this situation, but also win money, that you have a way to deal with this situation! I've learned what you've taught me, but I still don't know how to deal with it, only you haven't taught me! "

"Yes Tyler nodded. "But, we're not aiming at you to say that you've learned to hide something and don't teach you. We're aiming at you to say that you can go to the casino alone. We count cards as a team. Different people play different roles and have different division of labor and tasks. One person can't do it! "

"Division of labor and cooperation? Different roles? " Xiao Yao waved his hand and said, "can you tell me more about it?"

"We go to the casinos in groups." "There will be at least three people in a group," Tyler said. There are two card counters, one big player. One of the two card counters is responsible for early detection, detecting the trend of the deck on the card table, sending signals to big players, informing them to enter the game. Another card counter is responsible for controlling the field and reminding the big players nearby. Among the three players, the big player is the main player, and the other two are the assistants. Although they are auxiliary, they are indispensable. "

"At least three people? So I can't go to Vegas? " Xiao Yao turned to Yan Ke and said, "why didn't you tell me this before I came here?"

"It's not that I can't go." Yan Ke said, "although we have been blacklisted by casinos in Vegas, it does not mean that our card counting is over. We can teach you, and naturally we can teach others. During this time, we have been looking for new members of the card counting team. When we find a new card counting team member, we can go to Vegas with you. "

"When will it take to find new team members?" Xiao Yaodao.

"Soon!" Taylor said, "in the card counting group, big players are the main force, and they also have the highest requirements for all aspects of ability and quality. Relatively speaking, it's hard to find people who can be big players, and it's easier to find two assistant card counters. We think that your ability and quality are in line with the requirements of big players. What we have just taught you is what big players need to master. With you as a big player, it won't be too difficult to find two more assistants, and it's not expected to take long. We are at MIT! "

Xiao Yao nodded and looked at the people:" can you tell me who are the big players, who are the card counters, who are the early investigators, and who are the controllers? "

"I, Yu Gang and Taylor are big players. They are card counters..." Yan Kedao.

"Wait a minute," Xiao Yao interrupted, "you said a group should have at least three people, you only have seven people in total, and there are three big players?"

"The three of us are mainly big players. At the same time, we can also be competent as card counters and help others!" Yan Ke said, "fixed combination is easy to find, we will do some rotation!"

"Oh Xiao Yao nodded. Suddenly, he said to Yan Ke, "can you show me how the three of you work together? That's what happened! "

Several people looked at each other. Taylor nodded with a smile and said, "of course."
