"Brother Ding'an, what do you mean by this move?"

Seeing Shi Xiangxia suddenly make a move of "single official", Li Xiangping was equally surprised. You must know that the so-called "single official" in Go is a move without purpose, and it can also be considered as a move without any value. Before the game,

If you end up playing this kind of chess, it is certainly a problematic move.

It's just that although there was a problem with the move, Li Xiangping did not dare to question it immediately, not because it was too complicated, but because the problem was too simple. You must know that it is difficult even for beginners to play "single official" before all the official positions are collected.

A mistake you won't make.

How could a master like Shi Xiangxia make such a mistake? Therefore, Li Xiangping's reaction was the same as that of the people at the Chinese Chess Academy. His first reaction was to be surprised, and then he re-examined the chess game, wanting to see Lao Shi

Have you discovered any problems in black's chess pattern and need to make up for it here?

It's just that Li Xiangping has people close to professional level after all. The current situation of this chess game can be said to be very simple. Almost all parts have been finalized. The largest board only has 3 goals on the back hand. Therefore, it seems that

After a while, Li Xiangping couldn't help but ask.

"Ah, mistake, mistake, I forgot you explained to me that the rules of Go nowadays are different from those in the past. I am just out of habit..."

Before Lao Shi could finish speaking, Li Xiangping jumped up: "Ah?! It turned out to be a mistake. What's wrong with you, Lao Shi? You are a great chess master, how could you make such a mistake?"

Wrong, don’t you know that today’s game of chess is very important to me.”

After making the mistake, Lao Shi also seemed quite embarrassed. He explained in a low voice: "I'm sorry, little friend Xiangping, in the era we live in, this move... this move is indeed the biggest official move on the board...

..."

"Um?"

After hearing this, Li Xiangping was thoughtful. He seemed to have remembered something. After he re-examined the chess game, Li Xiangping burst into laughter. At this time, he finally understood why Shi Xiangxia committed such a low-level crime as modern people.

Error.

This is actually related to the rule of "returning the head" in medieval chess.

The so-called "returning the chess head" means that in ancient chess, after the end of the chess game, there are still more pieces. If the total number of black chess pieces at the end of the game is 4 pieces, and the white chess pieces are 5 pieces, then according to the thinking of the ancients, it takes at least one piece of chess to survive.

2 eyes work, 2 eyes are 2 eyes. According to the rules of medieval chess, the value of these 2 eyes cannot be calculated and needs to be deducted at the end of the game. The more pieces there are, the more deductions will be made. If the black piece survives 4 pieces, it will deduct 8 pieces, and the white piece will deduct 8 pieces.

If you live for 5 yuan, 10 items will be deducted.

So in a simple sentence: "One piece of chess takes 2 pieces", this is the core idea of ​​"returning the chess head".

Just because he thought of this, Li Xiangping immediately understood why Shi Xiangxia made the mistake just now. Because if this game of chess follows the "return the head" rule, then the move just now is indeed valuable.

Because the move Lao Shi just played not only connected the two black pieces, but also cut off the two white pieces. So with this increase and one subtraction, this move is considered by modern people as a "single official"

", in medieval chess, it has 4 goals.

This is the reason why Shi Xiangxia said "it's a matter of habit". This is actually what makes medieval chess more complicated than modern Go, an increase in complexity caused by rule issues.

In later generations, Li Xiangping often saw some shallow and ignorant people slandering ancient Chinese chess on the Internet. Some people with level 3 and 4 dared to criticize Huang Fanshi. The extremely confident among them even dared to criticize Huang Fanshi.

Commenting on their chess records, I thought that Fan Xiping's move was unintelligible and Shi Xiangxia's move was full of fallacies.

However, to be honest, more than 90% of such comments are unreliable, and more than 90% of the reviews are truly incomprehensible and full of fallacies.

Some people don't even understand the core idea of ​​"returning the chess head". Such people actually dare to criticize ancient chess. Li Xiangping can only say "haha" to this.

Take today's game of chess as an example. This kind of "one increase and one decrease" worth 4 goals is not the most complicated problem caused by the "return the head" rule. If a connection or cutoff also involves a robbery problem...

...Anyone who knows a little bit about Go knows that the complexity here will increase exponentially.

If you want to comment on ancient chess, you must first understand the complexity.

Well, Li Xiangping thinks that he is not a superficial person, so he can still understand Lao Shi's mistakes. However, what should I say, today's game of chess is a game after all, isn't it? Although it is just a game of online confrontation, it can

However, Li Xiangping defined this game as "a battle to defeat the opponent." Especially now that it is approaching the end and victory is in sight, will this move affect the final outcome?

"This... this is equivalent to stopping a move. At present, the back hand has the largest 3 eyes on the board, so this move is very likely to lose 3 eyes. If it loses 3 eyes... Hurry up,

Brother Ding'an, please hurry up, no, no, no, let's play together and see if this move will not affect the final outcome..."

Just when Li Xiangping was hurriedly preparing to re-judge the situation, something even stranger happened. After Shi Xiangxia made this very technical move, the other side didn't know what they were thinking. They didn't make a move for a long time.

, 3 minutes later, with a "pop", Ax Gang* Honinbo Xiudou actually chose to admit defeat in the middle of the game.

"Have you admitted defeat? What does Yan Qing mean? He has been stubbornly resisting here before, but now he has finally waited for my mistake. How come he gave up so readily..."

Of course Li Xiangping would not know that at this moment, at the Chinese Chess Academy, the people from the National Youth Team had another interpretation of Lao Shi's move.

When they first saw this move, the guys from the national youth team were as surprised as Li Xiangping. But their level was higher than Li Xiangping's, so they realized it was a mistake faster. It was just that the previous move was a mistake.

Why would an opponent who showed a very high level make such a low-level mistake? Just as everyone was talking about it, Kong Erjie suddenly spoke:

"Ha, I know!"

"Hmm? Xiaomei, what did you see? What does this move mean?"

"What else can you mean? They are trying to persuade you to surrender."

"Persuade to surrender?"

"I just checked carefully. Even if Black stops here for a move, he will end up with 6 eyes on the board. No more, no less, exactly half a goal."

Speaking of this, Kong Erjie shook his head and said with emotion: "Tsk, tsk, this guy is really awesome, who is this? With such fierce chess ahead, no one has time to judge the situation, right? Anyway, I didn't see it clearly. But this person

Fortunately, they not only judged it, but also judged it very clearly. When they made this move, they clearly told us: Look, I will "stop" at this moment, and it will be no more, no less, and I will win you by half an eye. Everyone said this

What's the matter if it's not about persuading surrender?"

Yan Qing and Ao Lang looked at each other, and Hu Yaoyu and Qiu Jun looked at each other. Although Kong Erjie's statement sounds a bit strange, it must be admitted that this seems to be the most reasonable explanation.

You must know that this is an online chess game. This kind of "persuading surrender" may rarely happen in real life, but it is not uncommon in online chess games.

For example, Li Xiangping once saw a game of chess played online by the "secret agent" who was the best player in the country in later generations. His opponent was a Korean chess player. He saw that he killed two pieces of his opponent's chess pieces, but the man continued to resist.

The little spy finally got impatient, and he made a "pop" sound of "one, one", which is the corner of the chessboard. This is a typical "stop move", which means why are you still playing?

After listening to Kong Erjie's explanation, Gu Dali was not a Korean chess player after all, so he laughed:

"Haha, it turns out he's trying to persuade you to surrender. He's very powerful. But just because he can see clearly, he is indeed qualified to persuade him to surrender. I'll admit defeat now. Brother Niu, come here quickly. If you want to help me avenge you, you have to follow me early.

Invitation extended….”

So just like that, around 10:10 in the evening, the match between the Beggar Gang*Honinbo Xiuqin and the Ax Gang*Honinbo Xiudou ended in this unexpected way.

When Li Xiangping pressed the "confirm" button, before he had time to be happy, all kinds of private chat messages came to him overwhelmingly, especially the news about gang leader Hongqiao Wolong.

Beggar Gang* Hongqiao Wolong: "Is that you in white? Haha, congratulations."

Beggar Clan* Honinbo Xiuqin: "Haha, it's okay. I've already told you that this amazing horse Honinbo Xiudou is no match for me. What about Boss Hongqiao? It's a blessing that I took the initiative to take the job, right?"

Beggar Gang* Hongqiao Wolong: "Haha, is that you in white?"

Beggar Clan* Honinbo Xiuqin: "It's me...huh? Boss, what do you mean? You asked me this twice."

Beggar Gang* Hongqiao Wolong: "Haha, it's nothing, white clothes..."

Beggar Clan* Honinbo Xiuqin: "Boss, what on earth do you want to say? Why do I feel that you are acting weird right now."

Beggar Gang* Hongqiao Wolong: "Haha, it's okay. I actually want to tell you something. Do you know who your opponent was just now?"

Beggar Clan* Honinbo Xiuqin: "I know, I know this guy's background very well. I've known for a long time that he is no match for me."

Beggar Clan* Hongqiao Wolong: "Let me tell you the truth in Bai Yi. The person you played chess with just now was Gu Dali."

Beggar Clan* Honinbo Xiuqin: "Ah?!!!"

Beggar Gang* Hongqiao Wolong: "This news comes from Lao Mei. You also know Lao Mei. His source of information must be good."

Beggar Gang* Honinbo Xiuqin: "Ah?!!!!!!!!!!"

Of course Li Xiangping knew it by this time. No wonder Hongqiao was hesitant in speaking. He must have doubted his true identity and was trying to find out who his gunman was.

Just when Li Xiangping was about to continue chatting with Hongqiao, other prompts appeared on the computer screen:

"The Ax Gang*Honinbo Xiudou has sent you an invitation to play."
