Regarding this ancient "Double Feiyan" formula, Li Xiangping really didn't want to talk too much, after all, this kind of Go concept is not clear in this kind of place. He himself is because he has a dog as a referee in later generations, and the dog seems to agree more with "starting and flying with two hands, not too tight", so he thinks that ancient chess is right in this formula.

However, is the dog's perception necessarily correct?

What if more advanced dogs emerge in the future, and they will be more in favor of the modern game of Go?

Is this possible?

Li Xiangping couldn't say clearly, and he couldn't be sure. Because in his opinion, if the problem rises to the level of "Go concept", it can actually be classified into the category of philosophy, which is very metaphysical and very god-like, and it is not a problem that he can discuss as a sophomore in high school.

It is precisely because of this that after simply saying a few good words to help Zhonggu Qi, he is ready to skip this question and continue to explain the subsequent process.

However, what he didn't expect was that he was about to jump over, but his partner didn't have this awareness, and she continued to entangle this "Double Feiyan" formula.

And the reason why Chen Ying continued to entangle, it was because Li Xiangping said casually, before ending this topic, he was going to make a simple mistake and correct a mistake about the old method of "Double Feiyan":

“..... Chess friends, pay attention, in the face of this move of white chess "support..... Yes, it is the feather root nine dan "support" in the small position of this chess, some chess friends like to "dig" a hand at this time, I tell you, this hand is very bad, not only vulgar, but also said that it is a big evil hand is not an exaggeration, so in the future, when you meet people and you play the "double swallow" formula, you must not take this step "dig" the way of playing......"

It was at this time that Chen Ying interrupted Li Xiangping's speech, and it is understandable that she interrupted, after all, the step of "digging" that Li Xiangping just mentioned was also considered one of the normal changes of "Shuangfeiyan" in the past, and this change was included in the "Go Dictionary" published by the Japanese to the "Go Formula".

"Ahh Xiangping, wait a minute, do you think this step of "digging" is a big evil? But... But in the past, wasn't there such a move? ”

Well, this question is relatively simple, simpler than the previous question, and it does not belong to that kind of metaphysical thing, so Li Xiangping replied with certainty:

That's right, this step of "digging" is a big evil step! ”

Chen Ying once again entered the praise mode: "Ah! Why? ”

Li Xiangping explained to everyone one by one: "First of all, Sister Chen Ying, you see, if white chess "digs" a hand like this, is it a little strange that white chess has its own chess shape? Especially the move that white played before ......"

Speaking of this, Li Xiangping pointed to a chess piece on the big chessboard, which was a chess piece played by white before:

"Then the position of this move is very awkward, what is it? This is what everyone often calls "Ding Si", the standard "foolish form" in Go, the efficiency is very low, so in Go, if you play a move, you will make your own sub-efficiency become low, such chess is usually not a good chess. ”

After Li Xiangping finished the first article, Chen Ying did not answer, and no one in the audience raised any objections. Indeed, this first reason is easy to understand, even beginners in Go know that "Ding Si" is the so-called "foolish form" that is very inefficient.

After a pause, Li Xiangping continued: "Of course, this is not convincing if you only have this one, although playing chess is to pay attention to the shape of the chess, but it is not only the shape of the chess, a game of Go, that does not mean that you can win the chess game if you play a beautiful shape......

When Li Xiangping said this, the chess fans on the scene began to laugh, and Chen Ying of course also laughed, and she said to Li Xiangping with a smile:

"Yes, yes, if you want to pay attention to the shape of chess, then Xiangping you seem to be the most unqualified, don't you often play some weird tendons when you play chess, and you still win so many championships."

"That's it, the people in the rivers and lakes say that they don't feel uncomfortable."

At this time, I don't know who roared and how, and as soon as these words came out, it naturally attracted a bigger laugh.

After everyone laughed, Li Xiangping also laughed happily, and he laughed and defended himself, saying:

"Hehe nonsense, who said that I don't pay attention to the shape of chess when I play chess, let me tell you, in fact, in my own opinion, I am the person who pays the most attention to the shape of chess, but my standard for judging the quality of chess may be different from others..... Sister Chen Ying, what do you think is the standard for judging the quality of chess shapes? ”

Chen Ying smiled: "How do I know, then Xiangping, tell everyone now, what do you think is the standard for judging the quality of the chess shape?" ”

"There is only one, efficiency, the sub-effect of the chess pieces!"

Li Xiangping paused and then said: "In my mind, there is only one criterion for judging the quality of the chess shape, that is, to see whether each chess piece you fall on the chessboard can play the highest efficiency, the high efficiency is the good shape, the low efficiency is the foolish shape, and not the other way around, you see its beautiful chess shape, then you think that its efficiency must be high, if you do this, it is obviously putting the cart before the horse." ”

Speaking of which, Li Xiangping did not continue to expand, because if he expanded on this issue, it would be a bit like criticizing the Japanese theory of Go in the past.

To tell the truth, in the past few decades, the group of chess players represented by Mr. Otake, the Japanese "aesthetic chess player", have actually been doing this kind of thing putting the cart before the horse, which should be one of the reasons why Japan is lagging behind.

After stopping, Li Xiangping began to tell the second reason why the "digging" was not good:

"Why do I say that this move of "digging" is a bad move? In this way, it seems that there is no convincing force just to say that the chess shape is good or bad, so let's compare it with the actual battle, the actual combat of black chess did not play this step "digging", but directly in the three three "pull" a hand, this is also one of the positive changes of "double Feiyan", as long as the two changes are compared, the good or bad of the "digging" may be able to distinguish very clearly. ”

Hearing Li Xiangping say this, Chen Ying cooperated very well to put the actual combat process on the big chessboard, and after she finished, Li Xiangping began to explain the problem by asking questions:

"Sister Chen Ying, you can compare these two changes now, although they were both fixed formulas before, what do you think of these two changes?"

"This ......"

"Let's talk about the real space first, after white chess "digs" like this, is this cheap in terms of real space? Is it possible to increase one's own reality? Or can it compress the opponent's real space? ”

"It seems to be about the same in terms of real space, and it's ......."

"And if you 'pull' it alone, white is a hard head, so the real space in the corners is actually more solid, right?"

"Yes, yes."

"Okay, now we have made the second point clear, that is, compared with the single "pull", the real and empty aspects are at a loss, at least they can't take advantage, this is the second disadvantage of this method, now let's talk about the third ......"

"Huh? Are there any drawbacks? Wasn't this considered a fixed formula before, how could there be so many shortcomings? ”

Li Xiangping said with a smile: "Of course, there are shortcomings, and Sister Chen Ying, I tell you, this third shortcoming, the problem is actually the most serious, let's put it this way, if this step "digging" only has the first two shortcomings, then this chess may only be called a vulgar hand, it is precisely because there is still this third shortcoming, then this step "digging" is a bad move, and a step is really like a fake bad hand. ”

"Oh? So what is the third drawback? ”

"Earlier, we compared the real space, now let's take a look at the thickness, Sister Chen Ying, you observe again, compared with these two pictures, how is the thickness of the two sides?"

This ...... "digging" and "single pull" compared to the same, their own thickness is about the same, but the opponent's thickness is very different, as if after digging, the opponent's chess is much thicker, Xiangping is not like this? ”

Li Xiangping smiled and nodded: "Then after "digging", how can you make the opponent's chess much thicker?" ”

This question is very simple, Chen Ying said with a smile:

"It's very simple, after "digging", the opponent's breakpoint does not exist, since there is one less breakpoint, this is a lot less places that can be used, then of course this chess can be considered thickened. ”

Li Xiangping smiled and nodded again, but this time he didn't nod to Chen Ying, but to the audience:

"Now everyone should know that this step of "digging" is a big evil step, right? So if you encounter this formula in the future, then don't go down to this step to "dig". ”

Chess fans listen to it with relish, especially those who are biased towards "technical flow", which is even more rewarding. Indeed, under Li Xiangping's in-depth analysis, even K-level chess players now know that this is a bad move.

What a joke, a move to reduce your own sub-effectiveness.

One move does not take any advantage in terms of the number of meshes.

One move has no effect on one's own strength, but it does strengthen your opponent's moves.

If such a move is not a big bad move, then what kind of chess in Go can be called a bad move?

However, it was such a move, and for a long time in the past, it was considered a "fixed play".

By the way, because the "Double Feiyan" formula is very ancient, it is also available in ancient chess, but in the "Double Feiyan Formula" listed by our ancient national players, this step of "digging" has never appeared.

So it's still the same sentence, haven't the derogatories been emphasizing what "evolutionary theory", the concept of "starting and flying is not too tight" and not talking about it, just like that, where did the modern Go before Go AI evolve?

"Okay, that's all for the changes in this "Double Swift", let's continue to look down and see what this game looks like now......"
