Go Legend

   Chapter 513 Half Year Summary Time

   Playing chess on the 21-way big board is undoubtedly very tiring.

   In particular, the two of them knew each other well, and their levels were comparable. More importantly, the two had an extremely correct attitude towards the game this time, and they played this game of chess with a pious mentality that was almost "exploring the true meaning of chess."

   Then such a chess game is naturally more tiring.

   From the beginning to the end of this chess game, another two days have passed.

   "Hehe Ding'an brother, it seems that I am slightly inferior after all." 閺��

   This chess game was played by Li Xiangping in black, and finally the board was 7-pointed, compared to the 8-pointed board of Lao Shi last time, so Li Xiangping said the above words.

   However, although he feels "a little inferior", Li Xiangping has no dissatisfaction, let alone "depressed", "lost" and other negative emotions.

   First of all, isn't it normal for him to be "slightly inferior" compared to an old monster like Ren Lao Shi who has lived for hundreds of years? This is completely acceptable. Since the heart thinks it is possible to accept it, of course it will not produce any negative emotions.

   The second and more important point is that by playing such a game of chess with an almost religious attitude, Li Xiangping really feels that he has gained a lot. Since he has other gains, of course he will not care about the outcome of this kind of chess.

   "Hehe, little friend Xiangping, you're polite, little friend Xiangping, do you feel now, did we take it for granted last time?"

   "Ah?! Hahaha Ding'an brother, did we think of going together?"

   After all, they have been together for so many years, although they have not yet reached the realm of "common hearts", but Li Xiangping still understands what Lao Shi said.

  What Lao Shi said of "taking it for granted" actually means that last time, the two of them had a "take it for granted" idea about how to judge the outcome on the 21-way chessboard.

   To be more specific, when Lao Shi played 8 goals last time, why didn’t the two of them say that the chess was won by Lao Shi? This is the reasoning of the two out of a "take it for granted".

   This "take for granted" is generated like this:

   On a normal 19-way chessboard, the current Go rule is that the black sticker is 6 and a half eyes or the black sticker is 7 and a half eyes. It doesn’t matter whether such stickers are accurate or not, let’s take this as a basic reference for the time being.

   Well, let’s look at the small chessboard first: on the 9-way small chessboard, can Black still stick 7 and a half or 6 and a half eyes?

   The answer is very clear: although I don’t know how many are appropriate to post, anyone who has played Go knows that on a 9-way board, black can’t post that much anyway.

   If you really want to post so much, then let two professional players play, and the black player will lose 10 games if he plays 10 games.

   Consider the situation of the 11-way chessboard and the 17-way chessboard

   Therefore, before the 19-way chessboard, you can get a simple inference: as the chessboard expands, the black chess sticks should be gradually increasing.

   The last "take it for granted" between the two came about like this: since the 21-way chessboard is bigger than the 19-way chessboard, shouldn't the stickers of black also increase accordingly?

   Just how much should be added? The two had no idea in their hearts and couldn't tell clearly, so last time when Lao Shi had 8 goals, they couldn't say who would win and who would lose.

   However, through today's second chess game, Li Xiangping had an obvious perception, that is, he now believes that the sticking eyes of this black chess are not increasing with the expansion of the chessboard.

   Tiemu must have a limit, or there must be a limit value, and even in the process of expanding the chessboard, there may be an inflection point. That is to say, when the sticker size reaches a certain level, it may not increase any more, and it is very likely that as the chessboard continues to expand, it will start to gradually decrease.

  The question of "limit value" is well understood, here is a little explanation:

  The so-called "post-eye" in Go is actually to offset the efficiency of Black's advance, or it can also be regarded as the average value of each move on the chessboard.

   If you understand the purpose of the post from this angle, then the question is simple: Since it is the average value of each move, can this value be infinite? This is of course impossible.

  Because Go is very complicated, but the chessboard is a closed space, a closed space with boundaries!

  Since it’s a finite space, then something like “Tiemu” must have a limit, and it’s impossible to keep growing like that.

   To give an intuitive example: If Li Xiangping is playing chess with Lao Shi on the 31-way chessboard, and Lao Shi ends up with a 15-game lead in black, then Li Xiangping would be too embarrassed to admit that he lost chess?

Well, Li Xiangping is not so cheeky yet, of course he is embarrassed, let alone 15, even if it is only 10, he must admit that he lost. There are so many chessboards with 10 meshes, no matter how big the board is.

  It is not difficult to understand the concept of "limit value", so what really interests Li Xiangping now is: since "Tiemu" cannot keep getting bigger, does it have an "inflection point"? If there is an inflection point, where will this inflection point occur?

   Does it appear on the most standard 19-way Go board that humans are currently using?

  Li Xiangping didn't know what other people thought, but when he started to think about this issue, he immediately thought that the truth was probably like this.

   That is to say: if there is really an inflection point in Tiemu, then the most likely place for this inflection point is on the most standard 19-way Go board!

"Brother Ding'an, I remember that before the Han Dynasty in our country, everyone mainly used the 17-way chessboard, right? It was not until the Three Kingdoms and the Jin Dynasty that the 17-way was officially abandoned and the 19-way was adopted, so do you know why people made this? trade-off?"

Lao Shi said with a smile: "No, in fact, in China, the 17th and 19th roads have coexisted for a long time. Even in the Tang Dynasty, some people used the 17th board to play chess. It should be after the Song Dynasty that the 17th board was officially withdrawn. The historical stage is completely replaced by the 19th road."

   Li Xiangping nodded after hearing this. What Lao Shi said was in line with modern archaeological discoveries. For example, some 17-way stone chessboards were unearthed in some tombs in the Tang Dynasty.

   However, at this time, Li Xiangping's focus was not on this aspect. He was more concerned about what the ancients did to consider that they abandoned the 17th road and adopted the 19th road.

   "Brother Ding'an, that's not what I'm asking. I want to know what the ancient sages thought when they thought of using the 19-way chessboard instead of the 17-way?"

   Lao Shi said: "It's very simple, the 17-way chessboard is unreasonable, and it goes against the way of yin and yang between heaven and earth. It is taken for granted by the 19-way chessboard."

   Li Xiangping was stunned: "Yi Li? The Way of Yin and Yang Six Harmonies?"

"Of course! Xiaoyou Xiangping, you must know: chess is a word, it is easy to change, and it is a decimal. A chess player, a transaction, has changed from one change to ten thousand, and there is no change, so that nothing changes. Changes are made to become gods. When gods arrive, they are almost transformed. They are in line with the surrounding sky and make their changes. Grasp them beforehand, hide spirits in secrets, and do not understand the origin of creation. It is difficult to say this.”

   "Stop, stop, brother Ding'an" Hearing that Lao Shi began to babble off his book bag again, Li Xiangping was really angry and funny, he forcibly interrupted:

"Brother Ding'an, I know that you are proficient in Zhouyi, but you don't need to show it to me. In fact, about this question, um, it is about why the 19-way chessboard can become the final choice of human beings. In my previous life, I listened to it. There is another more superficial explanation, do you want to hear it?"

   "Oh, then let's hear it."

   "It's very simple, this is actually a problem related to "equilibrium""

Li Xiangping really didn't lie just now. Probably in the early 1990s, some domestic experts really thought about this, and published a special research article on "Go World", discussing why the 19-way chessboard is the most suitable choice for everyone .

The core point of the    article is very simple: the reason why everyone chooses a 19-way chessboard is for the consideration of sub-effect equilibrium.

   When it comes to the sub-effects in Go, basically every move is composed of two parts: one, the efficiency of this move to take the ground, and the second, the efficiency of this move to take the external situation.

Among all the chessboards, only on the 19-way chessboard, these two efficiencies are the most balanced. On a chessboard smaller than the 19-way chessboard, the efficiency of taking the ground is obviously higher than that of taking the external potential. Conversely, the efficiency of taking the external potential should be significantly higher than that of taking the ground.

   And that article argues: It is to maintain a certain balance that people finally fix the Go board on the 19th way.

   Waiting for Li Xiangping to briefly explain this truth, he said to himself:

   "Brother Ding'an, what do you think?"

   "Well, there is some truth to this statement, and it has already hinted at the way of changing numbers, but Xiaoyou Xiangping, if you want to fully understand it, I still recommend you to study it."

   "Stop, stop!"

   Li Xiang asked with a heartbeat what was going on with his plug-in? What era is this, and you still want to seduce yourself to study Zhouyi? As a modern and promising young man, how could it be possible to study such a mysterious thing?

   Because of this, Li Xiangping decisively told Lao Shi to shut up.

   But after Lao Shi really shut up, Li Xiangping couldn't help thinking:

"Well, not only Lao Shi likes Zhou Yi, but it seems that Boss Wu also likes Zhou Yi in his later years. Is that thing really helpful to the practice of Go? Then should I think about it too? No, it will be many years later. It's okay, I'm so young now, and now I'm thinking about that kind of nonsense, isn't that making people laugh at me? So no, no, this kind of thing is definitely not allowed now"

  Since he has made up his mind to reject Lao Shi, and the question seems to have been explained clearly just now, at least at this time, the two have reached some kind of consensus, so Li Xiangping quickly changed the topic:

   "Brother Ding'an, this is what I think now. If you have no opinion, then we will use the 21-way chessboard for training in the future, and use the black sticker with 7 points as the criterion for judging the victory or defeat. What do you think?"

   "Haha, I have no opinion, everything is just like the little friend Xiangping."

   After he finished saying this, Lao Shi added another sentence without hesitation:

   "Hey, no matter what, if we can set this standard today, then we have gained a lot in this game today, at least pointing out the direction for future training."

  Li Xiangping nodded with empathy, knowing that it is very important to have a criterion for judging the outcome of such training.

  For example, when he was in the middle game, Li Xiangping judged that he was 8 points ahead of the board, so should he think he was an advantage or a disadvantage?

   Obviously, he must have a standard for judging victory or defeat in his mind, in order to better guide his next move.

   Well now, this standard is finally settled.

   I don't care if this standard is right or not. Anyway, such a standard doesn't need to be announced to the public. It is a matter between him and Lao Shi. From this point of view, this is of course a big gain in this game of chess.

   In addition to this gain, Li Xiangping had other gains, but at this time, he had no time to communicate too much with Lao Shi.

  Because the new round of armor will start soon after the two of them finish the game, and this round of armor is on the road again, so Li Xiangping must immediately join his teammates and rush to the field.

   Not only that, but at this time, the opening date of the new "Chunlan Cup" has also been determined, just on the 3rd day after the new round of armor. Therefore, for the next week or so, Li Xiangping has to travel around the field all the time.

   In the afternoon of the same day, Li Xiangping rushed to the airport to meet his teammates. The destination was the Spring City Kunming.

   On the 2nd day, Li Xiangping played the main team again, and there was no other reason for him to play the main team, because Xiao Li is currently in the Yunnan team. As a super foreign aid, he has been the best choice for the Yunnan team this season.

   However, when Li Xiangping went out to fight, he couldn't help but be stunned when he saw that the person sitting opposite turned out to be "Dragon Feihu".

   But when he saw Xiao Li playing in the fast chess stage, he suddenly understood everything. ​​​

   This must have been proposed by Xiao Li, and he wanted to touch him at the main stage, but with Xiao Li's character, he definitely wanted to touch himself at the Kuaiqi stage.

Not only Li Xiangping saw it, but the coaches of the two teams also saw it. So at the end of the game, after Li Xiangping's team "the main player won" again with a score of 2-1, Coach Wu laughed. The provincial coach joked:

"Hahaha, it turns out that Xiao Li wants to touch Xiangping so much? Well, I'll give you a chance. Don't we have to touch it again this year? It's up to you to choose next time. Which one do you want Xiao Li to go to? Just squeak in advance, I promise to arrange for Xiang Ping to go down to the same stage."

   Those who play Go are of course not afraid of this, so the coaches of the two teams high-five and swear.

   After finishing this game of chess, Li Xiangping rushed to Taizhou, Jiangsu, to participate in the opening ceremony of the "Chunlan Cup".

   Since he is the defending champion, he only has to play chess this time.

  Wait two days later, when Li Xiangping defeated Korean veteran Liang Zaihao relatively easily, the time has entered July 2004, and it seems to have entered the half-year summary time.

   It was only when someone started a half-year summary that he realized that since he lost to Li Canghao last year, Li Xiangping has only lost a game of chess this year, that is, he lost a game to Gu Dali in March, and then he has won all the way to the present.

   So at this time, "Who can stop Li Xiangping?", once again became a hot topic in the Go world.
