Yan Ke and others are MIT students, living in school dormitories, not looking for another place to live. Although it's the summer vacation and there are many vacant places in the dormitories, the beds in American university dormitories are still relatively private. It's not popular for friends to come to the dormitories, so Xiao Yao naturally won't squeeze them into the dormitories.

Cambridge is a famous university town with complete infrastructure, many hotels and good environment. Xiao Yao had already reserved the hotel in advance before he came.

Xiao Yao has been on a plane for about 20 hours. He will meet with the card counting team tomorrow. Naturally, he won't arrange any programs in the evening. Yan Ke and others send Xiao Yao to the hotel for check-in. After they invite Xiao Yao to have a meal and ask him to have a good rest, they leave.

The next morning, Yan Ke and Xiao Yao went to the hotel to meet with other members of the card counting team on MIT campus.

At MIT, the card counting group is not a student association recognized by the school. At most, it can only be regarded as an unofficial secret organization. However, the hardware resources of MIT are very rich, and it is very easy for students to find a few classrooms for activities. Xiao Yao and Yan Ke met in a remote classroom on MIT campus.

There are a total of seven members in this card counting group. Besides Yan Ke's three members, there are four other members. When Yan Ke and Xiao Yao arrived, the four members were already waiting in the classroom. After the meeting, Yan Ke introduced Xiao Yao and the four to each other.

The four men are three men and one woman. Judging from the skin color and appearance, the three boys are Caucasian, Latino and Indian respectively, while the girl looks like a mixture of East Asian and European Latino.

Xiao yaolai's card counting group learning card counting method is actually a "peach picking" behavior. Yan Ke three people in order to persuade the other four people agree to Xiao Yao to "pick peaches", naturally will introduce Xiao Yao to the four people in advance. However, Xiao Yao is here to learn how to count cards, not to hold a fan meeting. When Yan Ke introduced Xiao Yao, they focused on Xiao Yao's mathematical skills and relationship with them, not Xiao Yao's identity.

Yan Ke said that Xiao Yao was the roommate they met when they participated in the training of the Chinese Mathematical Olympiad national team in middle school. The ability to enter the training of the national team of Chinese Olympiad Mathematics is not bad. Yan Ke and his colleagues had some research achievements when they joined the card counting group. The reason why they started to study the mathematical model and method of card counting very early was also proposed by Xiao Yao. Therefore, the achievements they brought into the card counting group were also contributed by Xiao Yao. Moreover, they once agreed to go to the casino together to experience playing blackjack with card counting.

It is mainly for these two reasons that the card counting team agrees that Xiao Yao will come to learn how to count cards. Yan Ke didn't think Xiao Yao's star status was helpful for this, and they didn't even mention it to the four people in the card counting group.

In this meeting, when they introduced each other, Yan Ke did not mention Xiao Yao's identity as a star.

However, Xiao Yao is also well-known in the United States. Yan Ke three people do not mention, does not mean that the other four people will not recognize Xiao Yuan.

After greeting each other, the half blood girl stares at Xiao Yao for a while and suddenly asks, "Xiao Yao? Is your English name Yang? You're a member of "immortals"? The Chinese star who has participated in EVA show and all star masters

"It's me!" Xiao Yao nodded with a smile, "but I'm not a member of the band now that I've quit immortals."

"Dean, haven't they made a statement that I'm out of the band yet?" Xiao Yao said in his heart.

Recently, Xiao Yao is busy, and he doesn't pay attention to the news. But this kind of thing, Xiao Yao and Dean and others to show attitude, even if they have not declared, Xiao Yao will not urge. It's just a murmur in my heart.

"Oh, my God!" The girl named Sandra said to Yan Ke, "why didn't you tell me that your friend is a big star of China?"

"Does it matter?" Yan Ke said with a smile, "we let him learn how to count cards because he can learn it in a short time and do it well, which has nothing to do with whether he is a star or not."

"Yes The white boy named Taylor in the card counting group said, "our card counting group teaches him to count cards, which has nothing to do with whether he is a star or not."

"Yang, can you tell me which school and major you studied in?" Taylor turns to Xiao Yao again and asks.

"Ty, why do you ask that?" Sandra asked Taylor, "do you want to show the superiority of your MIT students?"

"Of course not." Taylor told Sandra, "I'm just a little worried about his ability in math."

"Yan told us that Yang once participated in the training and selection of the Chinese Olympic Mathematics National team, and got full marks in Mathematics in the Chinese sat exam!" Sandra said, "do you think they're lying to us?"

"No, I believe in Yan!" Taylor said, "however, Yang may have been a mathematical genius like Yan in middle school, but genius also needs to be learned. The fact that a member of the band "immortals" can perform in the EVA show and the masters shows that he is an artist and a star. I don't think a well-known entertainment star can spend much time studying and researching mathematics. He is a star with high reputation in the United States, which shows that his band playing is not a hobby, but a profession! ""It seems reasonable!" Sandra thought and nodded gently.

"Can you answer my question?" Taylor saw Sandra did not speak, turned his head and asked Xiao Yao again.

"First of all, I'm not only a band member, I'm also a professional actor and director." Xiao Yao said with a smile, "I'll answer your question again. My undergraduate study in China's Shencheng drama college, which is a professional film and television school, my major is the performance department! At present, he is a double degree master's student in the Department of director and performance of Huaxia Yanjing Film Academy. You can know from his name that he is still a professional film and Television College, and his major is still related to film and television. "

"Do you need to learn mathematics in Chinese film and television colleges and your film and television major?" Taylor asked again.

"No need!" Xiao Yao shook his head and said, "my bachelor's and master's majors are all arts majors, and there are no courses related to mathematics!"

"Ah ~" said Xiao Yao, the four non Chinese members of the card counting group were surprised and disappointed.

"Thank you for your honesty!" Taylor nodded to Xiao Yao, "but I'm sorry..."

"Wait!" Yanke, knowing what Tyler was trying to say, interrupted.

"Yan ~" Taylor looked at Yan Ke with some dissatisfaction.

Of course, Tyler would be dissatisfied with Yan Ke. However, compared with Yan Ke's interruptions, he was more dissatisfied with the fact that when Yan Ke and his three men introduced Xiao Yao to them, they didn't mention Xiao Yao's recent situation at all, and they concealed the four of them.

The four of them had heard from Yan Ke that Xiao Yao had participated in the training of Huaxia Olympiad Mathematics National team with them, and Huaxia sat got full marks. The total score was the first in their city, so they took it for granted that Xiao Yao was a mathematical genius and continued to develop in the direction of science and engineering as they did these days. Even if they didn't come to MIT like them, most of them studied in Shuimu University in Huaxia or famous universities in other countries. Unexpectedly, this person went to study art and didn't study mathematics at all in four or five years.

"Taylor," Yanke said with a smile, ignoring the dissatisfaction in Taylor's eyes, "now our card counting model has been made. Yang is here to learn how to count cards, not to help us study how to count cards. We don't need to tell him what mathematical principles are used in card counting, as long as he remembers those calculation formulas and tells him how to calculate and how to do it. So even if Yang didn't study the advanced mathematics knowledge of the University, he could also learn how to count cards. "

"But," Tyler said.

"I know!" Yan Ke once again interrupted Taylor with a wave of his hand, "what's the basis of card counting? First, need a strong memory, can remember used cards. Second, a strong mental ability, through the formula to calculate the size of the next card probability, from the probability to make the most favorable choice. Memory and mental arithmetic ability, gifted reasons, can also be improved through training. We have both talent and a lot of exercise the day after tomorrow. Even if Yang exercises less the day after tomorrow, if his talent is high enough, he will be no worse than us! "

"What did you say? Talent? " Taylor said.

"Yes," Yan Ke said with a smile, "we all think we are genius, mathematical genius, but Yang is our more talented genius! At that time, Yang was younger than us, but he was better than the three of us in memory and mental arithmetic, and much better. Even though Yang hasn't studied mathematics and trained in recent years, his talent in these two aspects is very high. We believe that his two abilities are still better than ours! "

"Is it possible?" Tyler has some doubts.

"Isn't that right? Let's test it and we'll know?" Yan Ke said, "we have already agreed to train and assess Yang. Now that Yang has come to the United States from China, we can't let him go back without doing anything? "

"What do you think?" Taylor turned to ask the other three non Chinese members.

Yan Ke, the three Chinese people, always advance and retreat together. Looking at the expressions of Chen Jiwei and Yu Gang, it's obvious that they all have this idea. Taylor doesn't think it's necessary to ask any more, so he only asked the other three non Chinese members.

"I think Yang should have a try!" Sandra said first.

"We're all here anyway, and we don't have any plans today," said Sam, a Latino from South America who took a deck of playing cards out of his pocket and shrugged. "It's OK to play!"

The Indian boy named Raji looks more introverted, doesn't speak, just nods.

"All right!" Taylor see everyone agreed, then nodded, "Sam, you test it, first test his ability to remember cards!"

“OK!” Sam nodded, put the two desks together, stood on one side of the desk, pointed to the other side and said to Xiao Yao, "please sit down!"

Xiao Yao smiles, moves a chair and sits in the middle of one side of the two combined desks. The rest of the group naturally stood around the table.

"I have a deck of playing cards in my hand now," Sam said to Xiao Yao as he removed the cards in his hand. "I will shuffle the cards first, scatter all the cards in order, and then deal according to the speed rhythm of the blackjack table in the casino. We calculate according to four players plus one Dutch official. We don't need cards. We issue ten cards each time and then buckle them up. You have to tell us what these ten cards are. Next, we play the second game, or ten cards. After the issue, buckle them up, and then you talk about it. Fifty two cards can play five rounds, as long as you can say all right, the test is over"Must all the colors and points be correct?" Xiao Yao asked.

"It's better!" Sam thought about it and said, "but if you can't remember the colors, it's OK to remember how many times a certain number has appeared!"

"Wait!" This time, Yu Gang said, "it's too hard! We have a way to count cards, not to mention the color, and even points do not need to remember so clearly! We take a few points as a code to record them together... "

"Stop!" Xiao Yao said to gang, "I haven't passed the test yet, so don't tell me your card counting method first! There are five or six sets of cards in the casino. In many cases, there are more than four players on the table. Now Sam only tests me one set of cards according to the situation of four players, which can be regarded as lowering the standard. I'm willing to accept this kind of challenge! "

“OK!” Sam takes out the big and small kings, throws them away, shuffles the rest of the cards, and then starts to deal.

Sam deals according to the blackjack rule. First in front of Xiao Yao made four, and then in front of their own hair one, and then five positions and each hair one. In addition to their own in front of the first card is buckled, the rest of all cards are directly open. When all the ten cards are dealt, Sam first lights up the card he is holding in front of him, and shows Xiao Yao a look separately. He makes a gesture and then holds all the ten cards in turn.

"Tyler, you put the cards away, you check them!" Sam said to Taylor, pointing to the ten buckled cards on the table.

Tyler understood Sam and reached for the cards on the table.

"Wait!" Xiao Yao grabs Tyler's hand that reaches for the playing cards on the table.

"What's the matter?" Sam and Taylor look at Xiao Yao curiously.

"I want to make it a little more difficult!" Xiao Yao said with a smile, "I not only remember the cards, but also remember their positions."

"Here!" Xiao Yao stretched out his hand and ordered his left most two buckled cards and said, "three diamonds and ten spades!"

Taylor reached out and picked up Xiao Yao's two leftmost cards, looked at them and nodded.

"Here, plum six and heart Q, here, spade nine and heart eight..." Xiao Yao ordered in turn, and finally pointed to the two cards in front of Sam and said, "finally, Sam, in front of you, two J's, spades and hearts!"

Sam picked up the two cards in front of him, looked at them and nodded.

The first round all guessed right, but the card counting team did not show too surprised expression. After all, it's just ten cards. They can do it. Even if Xiao Yao increases the difficulty of color and position, it is not impossible for them. The key depends on whether Xiao Yao can still remember so clearly after more cards.

He put the two cards in his hand in front of him. Sam looked at Xiao Yao and said, "originally, I was going to put away all the used cards, and then randomly ask you the number of times a certain number of points has appeared in the next few rounds. Since you want to improve the difficulty by yourself, I won't take these cards. Later, I will not only ask questions about the number of times a certain point appears, but also about the stack of cards that have been used in a certain position. May ask if there is a certain number of cards and decors in that pile of cards, may also let you say all the number of cards and decors in that pile of cards, can you do it

Sam did this, is to further upgrade the difficulty of the test, with the card count requirements are getting further and further away. However, after Xiao Yao took the initiative to upgrade the difficulty for the first time, Yan Ke and others didn't want to help Xiao Yao speak any more, and they all entered the theater mode.

"I don't know, but I'd like to have a try!" Sure enough, Xiao Yao didn't refuse and nodded with a smile.
