The "first dog move" that came out of the "generation of dogs", why is it said that "vulgar thorns" are not the key, and the subsequent detachment is the essence? To understand this problem, Li Xiangping believes that it is best to connect it with the original human method, and use the "dog move" to compare it with the human formula, then it may be possible to see it more clearly.

What appears on the board today is called "Kometo Retreat", which is one of the most basic formulas in Go, and it is a very ordinary, very simple, and at the same time very old and very classic formula.

It is said that this formula is very ancient, because since the Japanese began to give up the seat to play "Xiaomu Go", this formula has appeared, and it is said that this formula is very simple, because the number of hands in this formula is small, the structure of the chess type is simple, it does not contain how complicated the calculation path, and there is no "flying knife".

In addition to these characteristics, there are very few variations of this formula, and it has been almost unchanged from the day of its birth to the present, as was the case with Dao Ce and Xiu Ce hundreds of years ago, and still in the 21st century. It is precisely because this is such a classic formula, so analyzing the difference between it and "dog moves", Li Xiangping may be able to better understand the difference between human thinking and Go AI thinking.

Anyone who understands Go knows that when the Go AI plays that "vulgar stab", the human play is not like this, at this time, the normal progress of the "small eye to retreat the formula" is to "remove the edge" in the next step, and when the black chess finishes this move to "remove the edge", the entire local formula is completed.

As for why this step is "splitting the edge", according to the original human Go theory, of course, it is also very easy to understand, the black chess originally made into the "tiger's mouth" of the three pieces, at this time has not been completely stabilized, the so-called "two to dismantle three three to dismantle four", so at this time, the next step "dismantling the edge" is very necessary, this move not only makes the black chess more stable, but also has a certain value of the mesh.

By the way, it is not someone else who summed up such a classic Go proverb as "standing two and demolishing three three and dismantling four", it is Li Xiangping's body that is the external Shi Daqi Sheng, it is precisely because this saying is so classic, no one has ever objected for thousands of years, so naturally, no one has ever objected to this step of "small eyes to retreat", and no one has ever disagreed, and everyone thinks that this is the most normal progress.

And all this, until the birth of the "alpha dog", the situation changed!

So is it the "dog move" that overturns the Go proverb summarized by humans? From a strict point of view, it can't be said that even Li Xiangping, a person who has seen the power of Go AI, does not dare to make this conclusion easily.

However, only in terms of this "small eye support retreat formula", if the "vulgar thorn" made by the alpha dog is carefully compared with the human step's "side removal", then Li Xiangping still has to admit that maybe it is really a dog move that seems more reasonable, and this move is in line with a higher level of chess theory.

In other words, even until now, Li Xiangping does not think that the move made by humans to "remove the edges" is a bad move, but compared to the dog move, this move seems too ordinary, and it is the so-called mediocrity.

This is a bit like nitpicking, and now let's compare these two moves with the strictest eyes to see where the mediocrity of this "side-breaking" is.

First of all: if humans make this move to "remove the edges", then after this formula is completed, black will fall to a back move, and Alpha Dog's move will be "vulgar" and then take off first, and black will earn a first move locally.

Even if many people who don't know how to play chess, they should all know that the "first hand" in Go is better than the "back hand", so this first difference goes without saying, and the dog move that can earn the first move will get a point first.

The second point: the step of "dismantling the edges" under the human formula is actually not of much value at this time.

You must know that when this "small eye support retreat" appeared on the chessboard, this was not long after the overall situation began, a total of more than 10 chess, the chessboard is still very empty, this step of "dismantling the edges" is certainly a "big field", but it is by no means the largest "big field" on the current chessboard.

For example, in the game of chess between Alpha Dog and Lee Sedol, as well as in today's game of chess, after black took the lead, he immediately went to grab another "big game" on the chessboard, that is, let black form a "Chinese flow" formation on the other side.

There is no doubt that from the perspective of "big field" alone, the move that constitutes the "Chinese stream" formation is obviously more valuable than this move of "dismantling the edge". Therefore, this second round should also be a dog move to score.

The third difference between the two methods, Li Xiangping believes that this is actually the most important difference:

As we all know, there is a saying that "urgency" is greater than "big field" in Go, and the so-called "urgency" is actually the point of contention between the two sides. For example, if you don't play this move, then your own piece is likely to die, or if you don't play this move, you could have killed the opponent's piece of chess but couldn't kill it, then this kind of chess is called "urgency." ”

So now the question arises, can the move in the human formula "dismantle the edge", this move be called "urgency"?

The answer is obvious, this move is certainly not a 'hurry'. Therefore, the direction of this "side splitting" is the so-called saline-alkali land in Go, and the value of playing chess in the direction of saline-alkali land is certainly there, but it certainly does not involve the rise and fall of the two sides' formations, so from this point of view, this move is of course difficult to call "urgent".

The second angle: If black does not make this move to "split the edge", will the large piece of black die? Take a step back and say that even if you don't die, will you be miserable by white?

Yes, Li Xiangping thinks that this is the crux of the matter!

Because the original intention of human beings to play this move is to take this move as a "hurry", thinking that if you don't make a move here, then black may suffer a severe attack, so it is necessary to strengthen a hand, and it is precisely because this move has both the role of reinforcing itself, but also has a certain practical value, so for thousands of years, very few people have raised objections to this.

It's a pity that Alpha Dog thinks that this move is not a "hurry"!

And after seeing that step of the dog move, after careful research and a lot of actual combat verification, we must also admit that that step of "dismantling the edge" is indeed not a hurry.

The reason is very simple, the original "tiger's mouth" chess shape of black chess is actually very elastic, especially after the addition of that "vulgar thorn", the eye position is actually very rich, from the perspective of safety, the effect may be a little worse than the human move "dismantling", but it is impossible to be attacked by white chess very badly, let alone have the risk of life and death.

And this, in fact, is the real connotation of this step of the "first dog move"!

This dog move, first with a step 'vulgar hand' to strengthen itself, although from the degree of safety, this move may not be as good as the human move "dismantling the edge", but considering the first two advantages of this move, then in a comprehensive comparison, of course, the embarrassment can be considered that this step of the dog move is more reasonable, and the human move "dismantling the edge" is set off by it into mediocrity.

Is the connotation of this "dog move" very profound? Li Xiangping thinks that it is not profound, because such a move is only played by a "generation of dogs" after all, and everyone knows that a generation of dogs using "deep learning" algorithms is still learning human play, so its Go thinking is actually more or less imprinted by humans.

For example, I have analyzed so much just now, in fact, in a word, this "first dog move" of Alpha Dog is commonly known as the "rush first" method.

The biggest feature of this style of play is actually to give up part of the safety within the range that is acceptable to oneself, and then emphasize the rapid development of the move, and quickly seize other big games.

There are also practitioners of this kind of play among human chess players, and the most typical example of this is of course Mr. Wu Qingyuan.

Li Xiangping remembers that in real history, when McClymond Jiudan was explaining the game between Lee Sedol and Alpha Dog to Europeans and Americans, he emphasized it many times; In the chess of the alpha dog, he clearly saw the shadow of Mr. Wu, such as the "five-way sharp rush" that shocked everyone's attention in the back, this move is like Mr. Wu's chess.

Li Xiangping believes that in fact, it is not only that step, this seemingly unbearable "thorn" is actually in the same vein as Mr. Wu's Go thought, but from the formal point of view, this move is only "god-like", not like the 'five-way sharp rush' god shape.

Of course, Li Xiangping thinks that it is now meaningless to say that Mr. Wu is like an alpha dog, or whether an alpha dog learns from Mr. Wu, and when Go AI begins to learn from human chess games, then it has already left humans far behind.

It is precisely for this reason that when Ke Jie Ke Shaoxia watched Lee Sedol VS Alpha Dog, he left a sentence "Dogs can win Lee Sedol, but they can't win me".

Just at that time, Li Xiangping didn't think Ke Shaoxia was arrogant, after all, a generation of dogs still had a deep human Go brand, if the dog had not evolved, Li Xiangping thought that it was really impossible for humans to win it.

Back to today's game, when Li Xiangping sacrificed this "first dog move", Li Canghao began to slow down the speed of the fall, by 11:30 in the morning, the overall more than 30 hands, in this one-and-a-half-hour game, Li Canghao's time was half more than Li Xiangping.

Of course, the players who watch the game in the viewing room don't care about the time of the game, they only watch the progress of the game.

And at this time, whether it is a professional chess player watching the game or an ordinary melon-eating crowd watching the game on the Internet, everyone has expressed their feelings:

"Tsk, it seems that the stone Buddha will also be angry, it is understandable to think about it, in the face of Li Xiangping's bullying method, he is a vulgar hand and a precedent, so it may not work if he is not held responsible, and now next, Li Canghao should consider attacking the black chess block."

And in the game room, Li Xiangping, who was dragged into the chess game with all his heart, of course guessed his opponent's thoughts, and he knew that Da Li must be thinking of an attack route now.

Li Xiangping laughed silently!

Although there are only more than 30 chess moves at present, Li Xiangping knows in his heart that the game strategy he and Lao Shi jointly designed today should be considered a success.

Let's not talk about attacking in itself, Li Canghao said that he was good at it, just in terms of this chess form, this is not so easy to attack.

"Alas, the inertia and misunderstanding of human thinking ......"

Li Xiangping pretended to sigh like this.

At this time, Li Xiangping even saw victory beckoning to him.

So what exactly can this game of chess look like? The game continues step by step.
