The National College Student Chess Game Competition is a competitive event specifically for college student chess enthusiasts. At the same time, it is also the event with the highest gold content of all the contestants.

A total of 128 colleges and universities across the country participated

Held at the end of December every year, it includes 10 types of chess: backgammon, backgammon, dot grid, surakarta, amazon, phantom go, no go, Einstein, military and hex.

The event was hosted by the Chinese Chess Association and hosted by major universities in turn.

This year's contest was held at Kyoto University of Aeronautics and Astronautics in Kyoto.

In previous years, in this event, there was a figure of Tsinghua Chess and Card Club, and the results were remarkable.

In chess, Zhang Wenjie has participated in two sessions, winning first place once and third place once.

In the Go project, due to the presence of President Lian Qingfeng, in the past three years, it has won the first place in a semi-crushing situation.

In other chess sports, except for the more unpopular chess sports such as Surakar chess, the rest have performed very well.

Now, in another week, it's time to register for the competition.

According to the rules, the number of participants in each chess sport cannot exceed two per university.

At the same time, in order to limit the number of contestants, the total number of contestants from each university shall not exceed ten.

The Go project is a popular event in the National College Student Chess Game Competition, and most colleges and universities will send two players to this project.

However, Tsinghua University has the existence of Lian Qingfeng, a great god, and only needs to send him to sit firmly in Diaoyutai.

But this year......

Lian Qingfeng sat on the chair and smiled bitterly, "I'm afraid I won't be able to go to this year's competition." ”

Lian Qingfeng is already a senior.

Usually all kinds of internships, writing papers, preparing for graduate school entrance examinations or something, have kept him busy.

Therefore, at present, Zhang Wenjie is responsible for the management of the daily activities of the entire chess and card club. Lian Qingfeng just wants to come here for a walk when he is occasionally free like today.

The National College Student Chess and Card Game Competition, from registration to the end of the competition, takes at least half a month.

This time...... Lian Qingfeng really can't afford to delay.

But if he doesn't go, who will go?

In today's chess and card club, there are many students who play Go.

But even if there is one who doesn't even have half of Qingfeng's strength.

went, and it was also cannon fodder.

But it is impossible for Tsinghua University not to send people to participate in the big project of Go.

Therefore, the desperate Lian Qingfeng can only touch the mouse blindly to see if Cheng Nuo, a first-year member, will give him a surprise.

Now, he urgently needs someone to participate in this year's Go competition for him, continuing Tsinghua University's strong dominance in Go.

"Will it be a little?" Lian Qingfeng smashed his mouth carefully, pondered for a while, and slowly asked, "Then Cheng Nuo, have you ever studied Go systematically and systematically?" Or, what kind of Go interest classes have you signed up for before?"

Cheng Nuo shook his head, "No." ”

"When I was in junior high school, the doorman at the school gate and a cleaning uncle often went down there, and after watching a few plates, I would get a little bit. ”

"Uh...... All right. Lian Qingfeng was helpless. "That Cheng Nuo, if you are allowed to participate in the Go competition now, do you feel that you can win?"

"President, you won't really let him go, right?" Zhang Yunjie on the side knew what Lian Qingfeng's plan was, and couldn't help but wonder loudly.

Lian Qingfeng waved his hand, "Don't be impatient, it's not like I haven't decided yet." At the very least, I'm going to put it to the test. ”

Cheng Nuo was confused by what the two said, "Two presidents, what are you two talking about?"

"Don't speak. Lian Qingfeng took out a pair of Go from the drawer of his desk, "Come, let's talk to me in the next game first." ”

Cheng Nuo, who didn't know the situation, took the chess pieces handed by Lian Qingfeng in a daze.

Until now, Cheng Nuo didn't know exactly what was going on.

I don't know that Lian Qingfeng wants to take this opportunity to test whether Cheng Nuo is qualified to fight in his place.

The strength does not require much to be high, as long as you have half of yourself.

Lian Qingfeng thought so in his heart.

............

Go is a chess sport that originated in China.

Compared with chess, Go has a greater reliance on the player's computing power and logical reasoning.

Just like Alpha Dog a few years ago, it relied on its powerful algorithm, the computing power of counting 100 moves in one step, and the playing style of hundreds of top chess players, so that several world-class players could not raise their heads.

The calculations of Go are different from the calculations of mathematics. The calculation of Go must take into account the opponent's moves, predict and rehearse the throws of both sides according to the best moves...

Of course, no matter what type of calculation it is, it is easy for Cheng Nuo's brain to open a bug.

The top Go players will predict the opponent's next few moves according to their style and path, and make targeted targets in advance.

But Cheng Nuo had never played against Lian Qingfeng before, and he didn't know what his chess style was.

So......

When using computing power, Cheng Nuo can only use the elimination method.

That is, starting with the most unlikely hand, gradually eliminating and eliminating, and finally locking in the best move. This method greatly reduces the rate of missed calculations, but requires strong and rapid computing power.

This is no problem for Cheng Nuo.

The game begins.

Cheng Nuo is a black chess piece, the first move.

Smack!

Smack!

In the first few hands, both sides were testing each other, and they couldn't see the advantages and disadvantages.

However, after more than a dozen hands, Cheng Nuo's brain turned on the high-speed operation mode.

In his eyes, all the possibilities of Lian Qingfeng's fall in the next twenty hands flashed as quickly as a slideshow.

Possibility 1: White moves 18 at 10,5, Black at 19 moves at 15,11, White at 19......

Possibility 2: White moves 18 at position 2, 18, black ......

............

A total of tens of thousands of possibilities, Cheng Nuo calculated the response plan one by one.

Cheng Nuo, who had been in a state of shrinking defense, suddenly became extremely aggressive.

The atmosphere in the cubicle suddenly became tense.

Zhang Yunjie, who was sitting on the side, didn't dare to breathe, and there was only the sound of two people clicking and falling in the compartment.

......

White's 48th move.

Lian Qingfeng picked up a white chess piece with his index and middle fingers, and raised his wrist slightly.

Smack!

White falls.

A confident smile flashed across Lian Qingfeng's face.

On the opposite side, Cheng Nuo held a black chess piece and slowly landed in a position on the chessboard.

Smack!

The sound of falling children.

Suddenly, Lian Qingfeng, who was looking at the chess game, changed his face greatly.

The confidence on his face was gone.

"I throw in the towel. Lian Qingfeng said three words that he hadn't said for a long time.

"Senior, I've given you a lesson!" Cheng Nuo smiled.

Lian Qingfeng shook his head with a wry smile and looked at Cheng Nuo, "Cheng Nuo, your Go game was really learned from the doorman?"

Cheng Nuo spoke, "Sort of." ”
