"Do you have a USB flash drive? I'm finished and want to print it out and prepare to give them an exam tomorrow." Su Chen handed the laptop to Wang Wenyun, who was at the service desk who was busy with something.

"So fast?" Wang Wenyun was a little surprised, but soon she felt relieved. She thought Su Chen had downloaded the test paper online and had completed it by simply modifying a few data.

"There is a special photocopy room in the school. Just use it to print it for them. The school photocopy room has a special email address. You log in to the school's teacher system and use your account to send your test paper to the school's photocopy room. Notice how many copies you want to print, and you can go directly to get it." Wang Wenyun explained to Su Chen the usage of the school teacher system.

Huacheng Experimental Middle School has its own independent teacher system. In order to keep it confidential, it has established an internal email system for the communication of file information between internal teachers. This email system is installed on this teacher system.

"That's it, let's see." Su Chen suddenly realized that he knew that the school had a teacher system, but he couldn't use this thing normally. He had never followed this thing after recording the account password.

Su Chen opened the school’s teacher system, entered the account and password and logged in. He first checked the number of students in Class 1 and Class 8 of Senior High School on it. Finally, he found the email system in the system and sent a test paper to the school’s photocopying room, indicating the number of copies and the usage time.

After returning the computer to Wang Wenyun and Su Chen, he left the library with the book. He planned to go back to the office of the Sports Department. After all, there was his office location, and it was not a big deal not to go back.

Walking on the tree-lined path on the campus, Su Chen was a little dazed. The afternoon sun was still quite strong, but fortunately there were trees covering it.

"Ba, I'll eat!"

Su Chen, who was walking on the quiet tree-lined avenue, suddenly heard the sound. He was curious and couldn't help but follow the sound. The sound came from behind a small wood next to the tree-lined avenue.

Because of the obstruction of trees, Su Chen could not see the scene behind him, but there was a pebbles on the tree-lined path connecting the grove.

Su Chen walked to the end of the pebbly path and looked up. He saw that behind the woods was another world. There was a small pond with lotus planted in the pond, and there was a platform beside the pond, and there was a small pavilion on the platform. There was a stone tablet on the side of the platform, and the three big words "Ziping Star Platform" were engraved on it.

Looking up, the previous sound should have been made by the two people sitting in the pavilion.

Su Chen held the book and walked through the small pool. There were actually many goldfish in the pool. Unexpectedly, there was such a small world on this campus.

After climbing the Star Picking Platform, Su Chen saw clearly the people in the pavilion.

They were two old men, one of whom was wearing gold-wire reading glasses, with gray hair and a gardener's outfit. They were really gardener's clothes, not the kind of campus gardener who praised the teacher, but the one-piece gardener's outfit that cuts flowers and plants. There was a straw hat on the chair beside him, which looked like a flower and plants gardener.

Another old man looked much more normal, with casual clothes and black hair, but the age spots on his face betrayed his age.

Two old men were playing chess, and Su Chen also walked into the pavilion. When the two old men heard something, they raised their heads and saw that the visitor was a young man who was not aware of. Without saying a word, they lowered their heads and continued to look at the chessboard.

When they play chess, some students come to watch chess from time to time, and they are not surprised. Just like Su Chen, she is also a student who has nothing to do to watch chess.

Su Chen walked up to watch the chess game. It seemed that not long after the opening, most of the chess pieces on both sides were there. Su Chen took out his cell phone and looked at the time. He had classes in the second session in the afternoon, and there was still a lot of time left, so he just stayed to see others play chess.

Su Chen also likes playing chess because Su Chen thinks playing chess is a deduction process. What impact can each step cause? The other party will take another move to fight back against you. There are many possibilities this time, and each possibility will create a different situation, which rises to a probability problem.

It seems that someone has now developed a robot to play chess with professional Go players and chess players through data calculations. Su Chen was also a little interested, so he stood by and watched.

Su Chen stood beside him for ten minutes, because he didn't know whether the red chess pieces would go first or the green chess pieces would go first, so Su Chen didn't dare to ask the two old men because he didn't speak the truth about a real gentleman who watched the chess.

So when Su Chen stood beside him for ten minutes, he assumed that the red chess piece would go first, and then Su Chen began to calculate the direction of the chess game in his mind, and calculated each step, how should the green chess piece fight back. Finally, through the calculation, if there is no mistake, the red chess piece that masters the first move will win the game.

Calculate the situation of playing the red chess piece first, Su Chen's feet were a little numb. He found that the two old men had not moved yet. From Su Chen's appearance to now, the two old men had not yet left. The old man in the gardener's uniform was holding the red chess piece. He saw his right hand on his thigh, his thumb and index finger kept chasing his chin, and his left hand was placed on the table without moving, as if he was thinking.

"Isn't the red chess going first? Otherwise, my calculation result would be that the red chess is likely to win, and this old man wouldn't have thought for so long. Well, that must be the case. It should be the green chess piece going first." Su Chen stood for a few more minutes and found that the old gardener had not moved yet, thinking to himself.

Su Chen put the book in his hand on the stool beside him, and he also found an empty stool to sit down. Su Chen's legs were really numb, so he had no choice but to sit down.

After sitting down, Su Chen began to deduce the situation where the green chess piece went first. More than ten minutes passed by this deduction. Because the green chess piece had one less "horse" than the red chess piece, the red chess had more choices.

Finally, Su Chen finished deducing it. Su Chen finally concluded that the probability of winning the green chess piece is about 40%, which is still smaller than the red chess piece.

No wonder this old black-haired man had to think for so long, it turned out that his winning rate was relatively low.

I saw the old man with black hair holding two eaten chess pieces in his left hand and holding his right hand on the table and supporting his chin, looking full of concentration.

Su Chen has calculated the results when the chess pieces on both sides have not taken action yet. Su Chen can only sigh that he is old and his thinking ability has declined, and he may think a little slower than young people.

Time passed minute by minute, and the two old men had not moved yet. Su Chen could not sit still. He also admired the concentration of the two old men. If it were him, he would probably be unable to sit still. It seems that the word "young and energetic" is really good. If he could do so calmly and calm one day, he would probably be able to do things without any surprise.

"Who should?" At this time, the old man in the gardener spoke.

"I don't know either!" said the old man with black hair.
