At the beginning of the afternoon game, feeling that the opponent was likely to step into the trap set by himself, Li Xiangping walked into the game room in a happy mood.

Yes, for today's game of chess, to be more precise, shocked by Da Li's first game, Li Xiangping and his plug-in really carefully designed a trap.

Or rather, prepare a throwing knife!

Of course, when it comes to Li Xiangping's current level, especially the flying knife he and Shi Da Qisheng jointly created, it is certainly not comparable to ordinary flying knives. Li Xiangping even felt that if it was only in the human realm, then the flying knife he sacrificed today would definitely be classified as the highest level.

How advanced is it? ------

Isn't there a saying in later generations: the so-called invisible pretending is the most deadly, so if you use this sentence in Go, it is called an invisible flying knife, which can hurt people even more.

Compared with the ordinary "tangible" flying knife, Li Xiangping thinks that the one sacrificed today can be called invisible. Since it is an invisible flying knife, the lethality is not mentioned for the time being, compared with ordinary "tangible" flying knives, at least it is more concealed, and it is more difficult for opponents to detect, so such a flying knife is naturally more advanced.

Now the question arises, what kind of flying knife can be called "invisible"?

Well, for such a question, he doesn't know what other people think, but in his personal opinion, this throwing knife must have the following characteristics at the same time, so that it can be called "invisible".

The first feature: the basic chess shape of this flying knife, it is best to be the kind of big road goods, the more ordinary the better, the more common the better, and in this, it is best not to have the kind of weird-looking play in the whole process, and even the "tesuji" This thing is as little as possible, if there is such a chess shape as a carrier of a flying knife, then it is possible to practice an "invisible flying knife".

For the above article, the negative example is the famous "seventeen and a half tricks" in Go, although this trick is famous, why is it just a low-level throwing knife? That's because the trick is a bit weird, so weird that even K-level players see it, and this move seems to be saying: I'm a cheat, come and take the bait......

Since it has such characteristics, no matter how famous this trick is, it can only be a low-level flying knife.

The second characteristic that the "invisible flying knife" must have: that is, in the early stage of unfolding the flying knife, it must have many choices and many ways to play.

In other words, in a high-level throwing knife, it is better to have as many forks in the road as possible, because only then will the opponent be more likely to be confused and lose his vigilance.

The negative example corresponding to this article is like the "big avalanche" that Li Xiangping once performed.

Well, although Li Xiangping once used a "big avalanche" flying knife to win a game of Da Li, but to tell the truth, there are not many forks in the road in a chess type like a big avalanche, and there are quite a lot of plays that are "one way".

Obviously, if there are too many "one way" moves in a flying knife, then such a move must only be a "tangible flying knife", and it is not qualified to be called an "invisible flying knife".

The third characteristic that the "invisible throwing knife" must have: that is, in the process of casting this flying knife, it must not only involve local problems, but must be related to the whole world.

Well, this point actually involves the difficulty coefficient of the whole flying knife, in fact, if you want a professional chess player to take the knife, especially if you want a master like Da Li to get a knife, it must not be just a local problem, it must be a global difficulty.

Although there are throwing knives that are only of local difficulty and can be used by professional chess players, there is a prerequisite for this, and that is that such throwing knives must be contained in those classic chess shapes-----

For example, Li Xiangping's "big avalanche" that won Da Li last year, because this chess shape is so classic, the classic to the master's play has been deeply rooted, which is likely to allow you to succeed.

For example, last year, Li Xiangping didn't prepare the flying knife before the game, but Da Li bumped into it himself, which made him lucky.

The fourth feature of the "invisible throwing knife", that is, the theoretical support of this throwing knife, it is better not to be a more specific move, it seems that it should be a more ethereal chess theory.

Li Xiangping believes that this one is very critical, this one should be a watershed, that is, your flying knife must have this element, then it can be called an "invisible flying knife", otherwise if you only have the first three, no matter how high the difficulty coefficient is, it may only be called a "tangible flying knife".

It's very interesting, the flying knife that Li Xiangping prepared today just has these four characteristics at the same time, so he thinks that today's flying knife is very advanced, and it is an "invisible flying knife" that is like a fake.

Now let's correspond to it one by one:

First of all, the basic chess pattern of this throwing knife originated from the play method of "one small eye hangs low, and then three high clamps".

There is nothing to say about this play, of course, this is a very ordinary road goods, it is not an exaggeration to say that since the Japanese began to develop "Xiaomu Go", this routine is even the classic chess form of Xiaomu Go, in the past human Go development history, countless generations of masters have performed countless such changes.

So Li Xiangping chose this change as the carrier today, which is of course not easy to arouse the vigilance of the opponent.

Article 2: In this chess form as a carrier, there are quite a few forks in the road.

This article does not need to be described too much, chess friends with a little strength know that in Go, whenever it comes to the change of "pinch", there are usually many choices, and this kind of fork in the road is not one-sided, there are many choices for both black and white.

Especially the path that Li Xiangping chose today, because it is a "three-room clip", it can be regarded as a relatively loose way of pinching in Go.

It is precisely because of the relaxation that this allows both sides to have more choices, especially since many of the choices are not very compulsive, which of course makes it easier for the opponent to lose their vigilance.

Point 3: This throwing knife cannot be a local difficulty, it must be a global related difficulty.

Well, there is actually nothing to say about this, at the level of Li Xiangping and Li Canghao, every move and style will definitely be considered from the overall situation. To put it mildly, even if this flying knife itself only has local difficulty, it may not need Li Xiangping to guide it, and Li Canghao himself will make the problem global.

The fourth point: the theoretical basis that supports this flying knife is not a specific move, but a relatively illusory chess theory.

How so? Li Xiangping is now playing in South Korea, and he doesn't know what is happening in the discussion of the Chinese chess players in China, otherwise if he is there, he will definitely smile and be silent.

Because indeed, just like Chen Yaoyue said, the basis for him and Lao Shi to design this flying knife was precisely after studying the hundreds of chess games of dogs fighting in more depth------

(I can say a little more nonsense here, this should indeed be called "more in-depth research", because by now, Li Xiangping and Lao Shi are no longer satisfied with only staying at those particularly obvious dog moves that are completely different from human methods, but will observe some human moves that dogs don't like)

Li Xiangping and his plug-in found that the dogs seem to be particularly unwelcome to the common "pinch-attack" play in human Go, especially at the beginning of a game of chess, which has almost never seen a dog play.

So there is nothing to say, for such a situation, of course Li Xiangping will conduct an in-depth study with Lao Shi.

Although up to now, Li Xiangping and Lao Shi have not fully figured out why this is, but after studying for so long, they already have a certain experience, they just don't know whether their experience is right or wrong.

In fact, it is precisely for this reason that when he sacrificed this flying knife today, he thought that he could weigh the touchstone of Da Li in today's flying knife------

The reason is very simple, because the dogs never attack, but Li Xiangping took the initiative to attack today------

Of course, there is nothing to say, if there is a dog sitting opposite today, Li Xiangping thinks that it is good to say that he is pleasing here, and it would be good not to be defeated by the dog immediately.

Now it is replaced by the human chess player Li Canghao, although he is also an unborn genius among human chess players, Li Xiangping still thinks:

If Da Li can not suffer in front of this flying knife, then his comprehension of dog tricks has surpassed himself.

So has Da Li surpassed himself?

At 1:40 p.m., 40 minutes after the afternoon match, when Li Xiangping dropped his 63rd hand overall, he began to wait quietly.

Because of the next move, the answer should be revealed, if Da Li completely copes, then even if he really completely dodges this flying knife, and the overall situation may be ahead.

After seeing Li Xiangping drop his 63rd hand, Da Li looked slightly stunned, and then he fell into the long exam.

It was the longest long exam he had so far in this bureau.

Li Xiangping continued to wait calmly.

Yes, using the word "calm" at this time, Li Xiangping thinks there is nothing wrong with it.

Even Li Xiangping himself is a little strange, it is said that at this time, he should be a little worried, he should be afraid that Da Li will deal with it.

However, at this moment, Li Xiangping actually had a subtle psychology, and he vaguely hoped that his opponent would be able to deal with it.

Li Xiangping didn't know if he was noble, in short, at this moment, he really hoped that there would be human chess players who could understand the true meaning of dog moves!

It doesn't matter if the person isn't you!

It's just a pity that at 2:10 p.m. Korea time, it means that after about half an hour of long exams, Lee Canghao fell behind the 64th hand in the overall situation.

Seeing this move, Li Xiangping was slightly disappointed.

Of course, while disappointed, he also felt that there should not be much suspense in today's game.

An "invisible throwing knife" with 3 traps, after Da Li dodged the first two, he still couldn't dodge the third one in the end.
