"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 acting!" Xiao Yao said without blushing at all.

"Okay, I'm taking the test, not here to discuss my life and career choices with you!" Xiao Yao continued, "Excuse me, have you completed the test?

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

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

"Of course!" Taylor nodded, holding out his hand, "Welcome to the MIT 21 group." ”

"Join?" Xiao Yao smiled, "But I'm not a MIT student!"

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

"Okay, my pleasure!" Xiao Yao reached out and shook hands with Taylor.

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

"OK, I'm in for a treat!" Xiao Yao smiled, "This is your territory, you find a place, I'll pay!"

Xiao Yao, Yan Ke and others came over not very early, and after an introduction and greetings, plus two tests, it took a lot of time, and now it was almost time for lunch.

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

"I agree!" Yan Ke interjected, "He's a star, he's very rich, he should be made to pay!"

"Alright!" Taylor thought for a moment and nodded.

After the discussion was decided, the group left the school to have lunch.

Although Yan Ke said that he wanted to "eat a big family", in the end, everyone took Xiao Yao to a small restaurant not far from the school, and in terms of scale and decoration, it didn't seem to be a particularly high-end place. Xiao Yao invited guests to dinner just as polite, not to show off how rich he was, so he didn't object, and followed everyone into this ordinary-looking restaurant.

After everyone entered the restaurant to find a vacant seat and sat down, the waiter of the restaurant quickly came to greet everyone and brought the menu to everyone.

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

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

The menu of this restaurant is very special. The normal menu, including the name and price of the food. On the menu of this restaurant, there is nothing special about the name of the food, but the corresponding price position after the name of the dish is not a number, but a different mathematical formula. Moreover, these formulas are not simple four-rule operations or equations, but complex formulas involving advanced mathematics, more than 80% of which Xiao Yao can't even read, let alone calculate.

"Ha!" Seeing Xiao Yao's speechless expression, Taylor and the others all laughed.

"The owner of this restaurant is a teacher in the math department of our school!" Sandra explains with a smile, "The customers here are basically students from our school!

This restaurant is not far from MIT, and when Sandra said this, Xiao Yao understood.

"As you said, I've passed the test," Xiao Yao leaned forward and asked Sandra in a tentative whisper, "So, this isn't another test for me, is it?"

"Looks like you really haven't studied advanced math yet!" Sandra understood, smiling, "yes, it's not a test. ”

"Oh!" Xiao Yao breathed a sigh of relief and leaned back in his chair.

"But," Sandra asked, "you can't read the menu, how do you order and pay?"

"Cut~" Xiao Yao pouted, "I just can't understand the formulas on the price, why can't I understand the menu?" I'm a rich man, and I don't look at the price when ordering, as long as I know the name of the dish." As for paying, I will pay as much as the waiter says, I don't care!"

"Wow~" Sandra pursed her lips with disgust.

Taylor and others all knew that Xiao Yao, a star, must be a rich man, but after a morning of contact, they found that Xiao Yao had neither a star nor the kind of rich man's mannerism, and his impression of him was still very good. Now Xiao Yao deliberately mentioned the money in response to Sandra's ridicule, which in their eyes was witty and humorous, rather than showing off, not only not disgusted, but feeling a little cute.

Xiao Yao doesn't think that the students in schools like MIT are all nerds, especially those who want to use mathematics to count cards and use cards to win money in casinos, it is even more impossible to be nerds. Xiao Yao is also very interested in this group of people, and he has a certain affection, and he is also very affectionate.

So, the atmosphere of the meal was good. After a meal, Taylor and the others chatted well with Xiao Yao, deepened their understanding, and became familiar with each other.

After lunch, everyone took a short break and then went back to a classroom at MIT to start teaching card counting.

In the afternoon teaching, Taylor and others took turns. Someone is responsible for explaining the formulas and calculation methods used in card counting to Xiao Yao, and someone is responsible for demonstrating.

Xiao Yao's learning ability and efficiency are very good, and he does not seek to understand the deep mathematical principles and knowledge involved in the formula, but only to master the method, and soon understands and learns the method of card counting.

"I think I understand!" Xiao Yao said confidently after not too long.

The people in the card counting team did not seem too surprised, nor did they have any compliments, as if they had expected this result.

"Really?" Sam walked up to Xiao Yao with a bag and pulled out the playing cards and chips from the bag, "Then let's try it!

"Okay!" Xiao Yao was also a little eager to try, and nodded happily.

This time, unlike the morning memory test, it was conducted in a simulated casino. Taylor is the dealer, Sam, Raj and Sandra are all players like Xiao Yao, only Yan Ke and the three still do not participate, only watching from the sidelines.

Although Sam, Raj and Sandra played, they only played the role of ordinary passers-by in the casino, not Xiao Yao. In the following process, the bets and cards of the three of them were very casual, and everyone's focus was on Xiao Yao.

And Xiao Yao's performance is very good. Through the study of that period just now, Xiao Yao did understand and master the card counting methods they taught. After more than an hour, the chips in front of Xiao Yao had almost doubled.

"It looks like I can leave for Vegas tomorrow!" Xiao Yao looked at the chips in front of him, turned his head and smiled at Yan Ke and the others.

"What? you're going to Vegas tomorrow?" the card counting team was surprised, and Taylor asked.

"Yes!" Xiao Yao smiled, "If I don't go to Vegas, why should I come to learn card counting?"

"No," Taylor said, "my point is, you're going to go alone?"

"Yes!" Xiao Yao nodded, "I heard Yan say that all the members of the group will go to Vegas, act collectively, and cooperate with each other." But aren't you all blacklisted by the casinos in Vegas? I want you to go with me, but Yan says you can't go to the casino, so I'll have to go alone. ”

"Also," Xiao Yao looked at the chips in front of him, and continued, "It seems that this kind of thing can be operated by one person!"

"Really?" Taylor smiled, "The casino doesn't play three decks of cards, so let's try a few more decks?"

"OK!" Xiao Yao nodded.

He had heard that the casino 21 tables were usually played with five or six decks at a time. The difficulty of three decks of cards is indeed less than the actual situation, but Xiao Yao thinks that he has learned to count cards, and does not think that he will not win by adding a few decks of cards.

"We're going to use eight decks of cards this time!" said Taylor, pulling out five more decks of cards from Sam's bag.

"What?" Xiao Yao was slightly surprised, "I heard that casinos generally use five or six decks of cards!"

"Yang, there are also eight decks of cards, we have encountered them in the casino!" Yan Ke said.

"Okay!" Xiao Yao nodded.

Eight decks of cards are indeed more difficult than five or six decks, and even more difficult to calculate. However, Xiao Yao has enough confidence in his memory and mental arithmetic ability, and for him who has mastered the method of card counting, he is still confident that he can cope with this increase in difficulty.

From three decks of cards to eight decks of cards, the difficulty has increased a lot, but Xiao Yao's performance is okay, basically the chips are still slowly increasing, so Xiao Yao still looks relatively calm. But when Taylor raised the difficulty again, Xiao Yao was not calm.

"Do it all over again!" After switching to eight decks of cards, Taylor did not deal all the cards, but after playing seven or eight rounds, he put the waste cards back together with the unused cards.

The more cards are discarded and the fewer cards that have not been used, the more accurate the player's judgment will be. However, when there are many cards in the opening game, it is not that it cannot be played, Xiao Yao thought that Taylor saw that he did not show a decline in the first few games, so he started again, so he just shrugged his shoulders and did not object.

What Xiao Yao didn't expect was that after Taylor put the eight decks of cards back together, he didn't start dealing cards, but directly took out a large stack of cards, put them aside, and started with only the remaining cards.

As a result, the number of points and some special cards on the table cannot be estimated.

Xiao Yao immediately frowned and said, "Hey~"

"This kind of situation also happens in casinos!" Yan Ke said on the side.

Although Xiao Yao heard that Yan Ke seemed to have a hint of schadenfreude in his tone, he didn't open his mouth to question it, just frowned and nodded, motioning for Taylor to continue.

Judging from the card counting method that Xiao Yao learned just now, this situation is a bit overclass. When Xiao Yao was playing, the speed slowed down significantly, and the time to think about whether to play cards became significantly longer.

Although Xiao Yao thought about it for a long time, the situation did not get better. After more than ten rounds, the chips in front of Xiao Yao have obviously decreased. Counting cards is to play the probability, is to improve the overall probability of winning, the more times you play, the more obvious the effect, and there is no guarantee that every hand can win, so it is normal for the chips to become less in a certain period of time. More than ten rounds is not much, which does not necessarily mean that Xiao Yao's algorithm has a problem, but Xiao Yao obviously feels that he has a problem.

Xiao Yao was very embarrassed to cut off some of the cards at the beginning, but he didn't expect that after playing more than ten rounds, Taylor opened a new deck of cards that he hadn't used, and after shuffling the cards, he added some of them to the pile of cards to be dealt.

"Hey!" Xiao Yao saw Taylor's movements, and immediately shouted dissatisfied.

"Jan~" Taylor laughed.

"Don't tell me this is what really happens in casinos!" Xiao Yao said as he looked at Taylor.

"It's true!" Taylor said, spreading his hands, "we've really met each other. You know, we're not the only ones counting cards now, and it's not like the casino hasn't met card counters. Those tables that don't use snail card machines will use these additional methods to deal with suspected card counters when they find that the suspected card counter cannot be identified!"

"I'll go, and this kind of thing?" Xiao Yao glared, "So, wouldn't it be useless to play?"

"Lost confidence?" Taylor laughed, "Are you going to throw in the towel?"

"I'm not here to gamble with you!" Xiao Yao said, "What you taught me can't cope with such a situation at all." If you continue to gamble, it is pure luck. I'm not a gambler, it's boring to fight for luck, and there's no point in continuing to gamble. ”

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

"You're kidding me?" Xiao Yao looked at them and said, "Okay, I admit that I was too arrogant just now, and you haven't finished teaching yet, so I can't wait to say that I have learned!"

"Why do you say that?" Taylor asked.

"Yan told me that you've been to Vegas and have been blacklisted by the Casino League. Xiao Yao said, "Only if you win money, will you be blacklisted by the casino, and Yan also said that you did win money from the casino." If you have encountered this situation and can still win money, it means that you have a way to deal with this situation! I have learned everything you have taught me, but I still don't know how to deal with it, but you have not taught me yet!"

"Yes!" Taylor nodded, "but we're not saying that you've learned something and deliberately hiding something from you, but that you can go to the casino alone." We count cards as a team, different people play different roles, have different divisions of labor and tasks, and one person can't complete it!"

"Division of labor and cooperation?different roles?" Xiao Yao waved his hand, "Can you elaborate on that?"

"We go to the casino in small groups. "In a group, there will be at least three people. Among them, there are two card counters and one big player. One of the two card counters is responsible for early detection, detecting the trend of the deck on the table, sending signals to the big players to enter the game. Another card counter is in charge of controlling the field and alerting the big players on the side. Of the three, the big player is the main player, and the other two are the support. Although they are auxiliaries, these two are also indispensable. ”

"There must be at least three people, then I can't go to Vegas?" Xiao Yao turned to Yan Ke and the others, "Why didn't you tell me about this before I came?"

"It's not like you can't go. Yan Ke said, "Although we have been blacklisted by the casinos in Vegas, it doesn't mean that our card counting is over." We can teach you, and naturally we can teach others. In the meantime, we've been looking for new card counting panelists. Once we've found a new member of the card counting team, we can go to Vegas with you. ”

"When will we have to wait until we find new team members?" Xiao Yao said.

"Soon!" Taylor said, "In the card counting group, the big players are the main force, and they are also the most demanding in all aspects of ability and quality. Relatively speaking, it is difficult to find people who can be big players, and it is easier to find two card counters who can be assistants. We think that your abilities and qualities are in line with the requirements of big players, and 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 supporters, and it won't take long. We're at MIT!"

Xiao Yao nodded and looked at everyone: "Can you tell me, who is the big player, who is the card counter, who is the early reconnaissance, who controls the field?"

"I, Yu Gang and Taylor are big players, and they are all card counters..."Yan Ke said.

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

"The three of us are mainly big players, and at the same time, we can also be qualified card counters and play auxiliary for others!" Yan Ke said.

"Oh!" Xiao Yao nodded, and suddenly his heart moved, and he said to Yan Ke and the others, "Can you show me how your three-person team works together?"

Several people looked at each other, and Taylor smiled and nodded, "Of course you can!"
