This is a classroom for small classes. There are three rows of desks, each row of 6. Each desk is filled with fifteen chessboards, but they are all empty. Everyone is standing next to the front desk in the middle row, watching a netizen playing chess with a girl.

There were at least a dozen people watching, but as soon as Du Qiu entered the door, the focus of his eyes was on the girl holding a chess piece in one hand and holding her chin in the other. She saw her black and thin, wearing an orange T-shirt and a water-green lantern shorts, and wearing a pair of black plastic sandals on her feet. Although they were all new, the color was distorted and the style was old-fashioned. At a glance, you could tell that it was the street stall that her stepfather bought, and her eyes were involuntarily red.

This is the bad guy who throws ice into the quilt in winter and puts spiders on the mat in summer...

This is the heroic sister who was bullied and avenged me in front of all the teachers and students in the school...

This is the funny sister who is versatile and has her arms around me and dances in public...

This is the strong sister who is optimistic and cheerful, smiling and telling me not to cry before she passed away...

"Oh, Boss 8 is here!"

"Boss 8 also likes Goji?"

Seeing Du Qiu's expression dazed and turned a deaf ear to the netizens' greetings, Du Chunhua hurriedly pushed him and asked, "Brother, what's wrong with you?"

"Ah? It's nothing." Du Qiu came to his senses, raised his hand to respond to the netizen, and covered it up: "My mind suddenly went down just now. I had something to say, but I couldn't remember what it was."

"Tsk, I just said I'm confused, I think you're really confused."

The arrival of Du Qiu and others was like a big rock falling into a small pond, destroying the peaceful and peaceful atmosphere of the game in the classroom. Cheng Yiyuan seemed a little dissatisfied. He threw the chess piece in his hand and stood up in a huh. His tone was very simple and his voice was crisp, and he announced in a clear voice: "I lost this game, let's play the decisive game."

"Everyone is quiet first, what do you have to say to them before they finish the game." Du Qiu walked to the chessboard and looked at it, feeling full of pity and warmth, but he joked in a somewhat awkward voice: "Little sister, I lost a bit miserable."

"I can't help but lose if I can't help but play Goji. I gave up on purpose." Cheng Yiyuan looked up at him and said confidently: "If there is a ban on the final game, I will definitely win him!"

The old sister has not yet grown up at this time. Apart from her big eyes, she can't tell how beautiful she is. She is wearing simple clothes, but her small body is straight, like a bud in early spring, like a little eagle spreading its wings, exuding a lively and high spirit, which is very cute. Therefore, as soon as she said that, someone immediately cheered: "One yuan is good, my sister supports you, and you will bet 10 yuan for the final game and you will win."

At this time, Du Qiu found that Xiao Wu was also there, sitting by the desk beside the window, with a bunch of colorful change in front of him. It was obviously a bet on the banker's side. Lin Jinyan half-kneeled on the stool opposite her, holding a few red banknotes of one dollar, like a little gambler, and shouting in a silence: "Sister Yiyuan, I support you, I also bet 10 yuan!"

The words of the boy made everyone laugh. Du Cunzhi stepped forward and picked him up, slapped him in the butt, scolded with a smile: "Little bastard, I didn't discipline for an afternoon and actually learned to gamble. That's all right."

Chen Zhiyang was always worried about the big black dog at the door. After smiling in a fit-of-view manner, he stood on the podium, made a move of pressing down with both hands, and urged loudly: "It's getting late, hurry up and play. There are other activities tonight, don't delay it."

Du Qiu stepped forward and helped Cheng Yiyuan clean up the chess pieces in the previous game, and asked, "Do you know the rules of banning hands?"

"Of course I know, my dad taught me, otherwise how dare I come to participate in the competition."

Ho! So confident?

The old lady has a lively personality, likes movement but not quiet. She has never played Goji in the time and space before traveling through time. Why has she suddenly become a genius little chess player now...

In the eyes of many people, Gozi is just a game played by children, and it is difficult to achieve elegance. In fact, this is not the case. Under the constraints of professional rules, Gozi is a very technical chess sport.

If you make an analogy, Go is a national-level battle, chess is a regional-level war, and Gozi is a battle in the elevator. In a narrow and fierce environment, the sword is bloody, and the person who takes the first action has a great advantage. Therefore, as early as 1899, Japanese chess players found that if there was no restriction, the first black chess can win by 10%. This view was proven by mathematics and computers in 1992.

In order to limit black chess, the Japanese people have been exploring for many years and have understood a set of rules called forbidden hands, which prohibits black chess from playing double three, double four, long-range layouts, even for defense, they are forced to play. This not only reduces the probability of black chess winning, but also adds a new way of winning to the white chess. There is no need to connect five pieces into a line. As long as the black chess can be forced to get out of the layout that should not be taken, it is considered a win.

This set of rules is prepared for professional competitions, which are quite complicated and will be difficult for amateurs to adapt for a while, so a compromise three-game two-win system was adopted at the Internet conference. The first two games were unstoppable, and one person held the black one at a time. If the score was 2:o, it means that the strength was very different, so there was no need to compete again. If it was 1; 1, it means that the strength was relatively similar, and you can use the rules with a forbidden hand to decide the winner.

In addition to the banned hands, a rule of five-handed and two-double play is also added. Five-handed and two-double play means that when the black chess reaches the fifth hand, two-double plays must be placed on the board with two asymmetrical positions, and the white chess decide which one is considered a move. This is a new rule that only appeared in 1988. Because after decades of development, even if there is a banned hand, the winning rate of black chess is still far from that of white chess, so we have to limit it.

"Do you two negotiate to choose black and white chess, or toss a coin?"

Cheng Yiyuan imitated the common movements in costume TV series, raised his right hand flat, made a gesture you asked for first, and said, "I'll do whatever I want, you can choose."

Her eyes were clear and her expression was serious. She sat and stood upright, showing her attitude of respecting her opponent and playing seriously. Although her movements were a bit nonsensical, they did not make people feel ridiculous. Instead, she had a calm and generous, polite and kind style. Du Cunzhi said to Du Chunhua when he saw this: "This little girl is good, she does things like you did when you were a child."

“I think it’s a bit like that, too.”

The netizen sitting opposite was a fat man with square head and big ears, whose online name was "Big Head Fish". He may have been infected by Cheng Yiyuan and did not show the arrogance or humility of adults towards children. Instead, he took out a coin and said, "Twish the coin, who guesses the right one, who is holding the black man. This is fair. Which side do you choose?"

"I choose the national emblem."

As a result, Cheng Yiyuan guessed wrongly and got the white chess. Bighead fish got the black chess. As soon as the two started, they only made four pieces. Du Qiu sweated for his sister in a cold sweat, feeling that she was about to lose.

Gozi chess originated in China and flourished in Japan. When Du Qiu went to Osaka as an exchange student, in order to experience foreign culture and hook up with foreign girls, he participated in the school's interest club and studied it carefully for a while. So just now, he heard that his mother was watching Gozi chess competition, so he came over temporarily.

In Goji professional competition, there are 26 fixed starts. Among them, Huayue and Uratsuki are recognized as the two most advantageous ones in Black. Even with the restrictions of banned hands and five-hand two-player, there are still more than three ways to win. You can even use software to find bug-level "carpet score". "Carpet score" means that Black chess doesn't have to care about white chess at all. You can follow your own steps, even if your opponent is the world champion, you will definitely win in the end.

The bighead fish starts with Huayue. If he has memorized some kind of chess score and follows a fixed routine, the elder sister will be in danger...

However, there was no formal professional Goji competition in China in 1995. There should be very few people who know that they will win. If they have not memorized the score, taking advantage of the game does not mean a stable win. My sister still has a chance...

Just as Du Qiu was thinking about it, Bighead played two black chess in the fifth move. Cheng Yiyuan took away the one that posed the most threat to her, completed the five-hand doubles, and then played the sixth white chess in the g1o position on the left.

"It's bad. This is wrong. I can't defend against black chess at all. I should play it..."

"Shh, a gentleman who doesn't speak, don't talk nonsense."

Du Chunhua gently touched Du Qiu with his elbow and asked his point with his eyes. Du Qiu did not rush to express his opinion. Instead, after the bighead fish played the seventh hand, he closed his hands as a microphone, and whispered to his mother to bite his ears: "It's already won."

"Is that true?" Du Chunhua stood on tiptoe and looked at the board with only 7 pieces in total, half-believing and half-doubting: "Can you see it now?"

"You ask Teacher Cheng, he seems to be going out."

Du Chunhua looked up and saw that Cheng Siwei, who was originally standing behind Cheng Yiyuan, gave up his position to a short netizen, walked out the door, and asked, "Teacher Cheng, where are you going?"

"I'm afraid that Xiaotian will scare the passers-by and go outside to watch it."

When Cheng Siwei walked to the door, Du Qiu raised his index finger, turned his wrist, drew a playful horizontal hook to his back, signaling his mother to follow him. Du Chunhua felt the joke, gave him a fierce look, and whispered: "It's not the chess played by Teacher Cheng, how could he know?"

Du Qiu smiled but said nothing.

After Huayue started, Black chess had at least three ways to win, but Cheng Yiyuan's move seemed to be ineffective in defense. In fact, after playing the 6th move with hidden murderous intent, Black chess only had one way to win, and the 7th move was very critical, with only two points to play. If you don't see it, you will soon collapse and lose.

My sister is a strange girl with motor nerves. Even if she suddenly becomes a Wonder Woman or kills a girl, I believe that she will become a genius chess player, but I don’t believe that she will become a genius chess player…

This very skillful trick must have been thought of by the stepfather of the chess fan who takes both Go and chess...
