I remember that before the birth of Go AI, Li Xiangping heard a non-well-known professional chess player say: In fact, so far, human understanding of the middle of the chessboard is still pale and weak.

Li Xiangping deeply agrees with this.

Especially after seeing Go AI wreaking havoc on mankind later, I believe that not only Li Xiangping, but more people should have a deeper impression of it.

So why does the middle belly of the board become a difficult part of Go? For example, in today's game of chess, a person of Li Xiangping's level has no clue about the selection of the mid-belly, and even a human chess player like Mr. Masaki Takemiya is recognized as a master of the mid-belly, and even he can't say why for a while.

This is, of course, because it is often difficult for human chess players to find the right direction of thinking when choosing a mid-belly point.

Of course, the selection of the mid-abdomen requires specific calculations, but in quite a few cases, the mid-abdominal selection problem seems to be more than just a specific calculation problem, but also requires your judgment to cooperate.

So in this case, is it mainly based on calculation or judgment? Or what proportion should both be? Of course, no one can figure out such a problem, and Li Xiangping even believes that even if it is a Go AI, it may be more accurate than humans, but it may not have been fully understood.

It is precisely for this reason that the problem of choosing a point in the middle of the chessboard, which has always been an ultra-difficult Go technique, belongs to one of the most difficult "virtual calculation path" problems.

It is also for this reason that in the history of the development of human Go, if there is a chess player who can play this kind of mid-belly skill, it will always be highly respected.

For example, since the birth of Go, it can be said that even in the field of human beings, there have been countless wonderful moves, but in terms of popularity, on the degree of respect for the wonderful hands, that step "The Wonderful Hands of the Red Ears" seems to be ranked in the top three of the human magic hands no matter how it is arranged.

Why is this happening? Li Xiangping believes that in addition to the fact that this trick comes with a bit of a legendary story, another most important reason: that is, the trick of choosing a point in one step!

This kind of trick is inexplicable, no one knows why Xiuce's predecessors suddenly played there, and even many years after the appearance of this move, there are countless chess players who have tried to interpret this move in detail, and among the interpreters, there are also top masters such as Wu Qingyuan and Mu Gu Minoru.

However, no one has ever explained it clearly, at least Li Xiangping has not seen it, and any kind of interpretation can be truly convincing.

However, it is a wonderful hand, the kind of magic hand that is truly "a wonderful hand", the kind of magic hand that everyone is convinced of, and everyone who has seen it feels pleasing to the eye, and even can move people.

And just now, when Li Xiangping dropped that move according to Lao Shi's instructions, his first feeling was that this was a good move, a good move similar to the "wonderful move of the ear".

Yes, although at the first time, Li Xiangping actually didn't understand what this move meant, because this move was completely beyond his expectations, just now when he was thinking about choosing a point, he didn't think about this place at all, but Go is so wonderful, when he saw the chess piece that he landed on the chessboard, he felt that this move was pleasing to the eye, and this move even moved him a little, so he intuitively thought that it was a good move.

Of course, Li Xiangping is also a professional chess player now, and he is a professional chess player whose level is not low and he hopes that he can continue to improve, so his next reaction is, of course, to try to interpret this chess hand, so as to understand what it means to play this chess hand.

And at the same time that Li Xiangping tried to interpret this chess hand, of course, everyone in the viewing room was also interpreting this chess hand, and the interpretation of the viewing room was still headed by Masaki Takemiya, and Mr. Takemiya was still looking at the chess game for 3 minutes, still looking demented, and repeating a sentence repeatedly in his mouth:

"This ...... It looks like a good move, but it should be a good move! But, but...... Can Go still be played like this? ”

And seeing him like this, Dazhu Hero was not satisfied, he took the chess game from Wu Gong and looked at it himself, and not only Dazhu, but also the situation here attracted Mr. Lin Haifeng and others, so in the next moment, the "bamboo forest" in the Japanese chess world was also interpreting the chess that Lao Shi had just played.

After a few more minutes, Mr. Otake Hero sighed:

"Good chess, it's really a hand full of extraordinary imagination, as soon as this chess hand comes out, it seems to have suddenly solved the difficult game of white chess."

Mr. Lin Haifeng didn't keep staring at this side in front of him, so his reaction was a little slower, and after spending a few minutes going through the previous process again, Mr. Lin didn't hesitate to praise:

"Yes, it is indeed an extraordinary hand, this Chinese teenager is really a once-in-a-century genius, I think this chess hand should be comparable to the "wonderful hand of the ear red" of Xiuce Chess Saint, right? ”

Interestingly, although Mr. Otake Hero also agrees that this is a good move, he doesn't seem to agree with Mr. Lin's statement, he glanced at Mr. Lin and said:

"Oh? Does Mr. Lin think this is like a "wonderful hand with red ears"? I have a different opinion. ”

"Huh? Mr. Otake means ......."

Dazhu Hero sighed: "Seeing this hand of chess, I think of a sentence that Zhang and his predecessors have said, Zhang and the chess saint once said: no attack, no killing, no living, no encirclement, this is the highest level of Go, Mr. Lin, you look at this hand of chess, do you already have a little bit of this charm?" ”

Of course, this evaluation is higher, higher than the evaluation of "Ear Red Skill", Mr. Lin smiled when he heard it: "Haha is good, not attacking, not killing, not living, not surrounding, this chess hand has indeed achieved these four points at the same time, good chess!" Today, even if you only see this move, it is already worth the trip. ”

Let's not mention how the two old-timers blow each other in business, by this time, Li Xiangping in the game room almost understood this chess hand, and after reading it, Li Xiangping also had a very mysterious feeling, he felt that after understanding this chess, it seemed that even his own realm had improved.

So where did Lao Shi play this chess move? Why do so many chess players marvel at this move after understanding it? To explain this problem, it is necessary to re-sort out the previous situation.

When this game of chess was played to about 70 moves, due to Mr. Zhao Zhixun's previous series of simple and fierce plays, white chess faced a very realistic problem, that is, at this time, white chess did not have a decent basic skill, so before Shi Da Qisheng's hand, everyone thought that white chess needed to "encircle" a hand, so it was better to maintain the balance on the ground first, otherwise the more you go to the back, you may not even have the opportunity to "encircle", because with the increase of chess pieces on the chessboard, Then if you simply enclose the land, it will only get smaller and smaller.

And because before this move, black had already made all the pieces on his chessboard, so it can't be said that the overall situation is thick, but at least it has been stable everywhere. So in this situation, the master knows that it is not easy for black to "encircle" the "encirclement", and this kind of play that is simply used to encircle the air is not only inefficient, but also violates the rules of chess.

However, in the current situation, white seems to be able to only encircle the air, which is the difficulty of white chess before, and it is also the reason why everyone thinks that white chess is difficult to play, because at that time, even a master like Mr. Masaki Takemiya did not help white find any very suitable moves.

It's just that Mr. Wu Gong didn't find it, but Shi Da Qisheng seems to have found it, and he seemed to have successfully solved this difficulty with this chess move just now.

It must be mentioned in particular that Lao Shi's move just now still falls in the middle of the abdomen, rather than moving to other places on the chessboard to play chess, otherwise it is not called solving the problem, but creating a clue to transfer the contradiction.

So now the question is, since it is also playing chess in the middle of the abdomen, so there are so many masters in the research room, why haven't everyone found Lao Shi's selection point? Could it be that Lao Shi's mid-abdomen feels even more awesome than the dignified "cosmic flow" Mr. Wu Gong?

It is not clear whether there is a better than Mr. Wu Gong Li Xiangping, but what Li Xiangping is clear is that Shi Daqisheng's mid-abdomen must be much more awesome than his current self.

After understanding the meaning of Lao Shi's chess move, Li Xiangping understood very well why he couldn't think of this choice:

Because of Shi Da Chess Sage's chess, he didn't stand on the word "wei" at all!

Yes, when everyone thought that they should be "encircled", Lao Shi did not go to "encircle", which is where the intention of this move is higher.

Of course, it's just that "no encirclement" is nothing, and it doesn't seem to see any cleverness, the real cleverness of Lao Shi's chess is that:

This move looks "not around", but it looks like it is "around", after white has more of this hand on the board, that look still looks like it is leaking everywhere, and black seems to have many ways to penetrate this look.

However, as long as you carefully calculate, you find that after white has more moves, black seems to be really not so easy to act rashly, because this piece of white has already put on a combat posture-----

To use an inappropriate analogy, Lao Shi's chess move, that is, when others thought he should tie his fence, he did not go to the fence, but held a stick in his hand, and waited for others to rush into his room at any time, and then he would close the door and beat the dog.

Lao Shi's way of thinking is undoubtedly a very profound way of thinking.

And such an idea is precisely the idea of "no attack, no killing, no living, no encirclement" put forward by the Japanese chess saint Zhanghe back then.

At that time, Zhanghe believed that this kind of thinking was the "highest state" of Go, and he personally pursued this state of affairs all his life.

To be honest, whether this is the highest level of Go or not, Li Xiangping doesn't know at all.

The only thing he knows now is that with this move, White has managed to open the position, and the game will enter a new pattern.
