The "iron weight" of the Go style is a very old change, how old is it? It is so old that it was only popular in the Song Dynasty and the Ming Dynasty, and even in Lao Shi's time, this change was no longer common.

It's interesting to talk about some of the archaic formulas in medieval chess, which usually have two characteristics. The first feature: many ancient formulas usually have a nice name, and the second feature: all the formulas with names in the middle and middle chess, and the variations of these formulas are often extremely complex.

Needless to say, the name is good, just look at the names of "Double Flying Swallow", "Inverted Weeping Lotus", "Jinjing Column", "Jade Screen", and the comparison between the "Great Avalanche", "Great Oblique", "Muramasa Demon Knife" and so on created by the Japanese.

As for the "disguised Chinese stream" and "Vietnamese stream" created by modern people, to tell the truth, if you compare the cultural conception alone, these things will not be made up at all, and there is no comparison at all.

There should be no controversy about saying that the name of the medieval formula is good, but when it comes to the complexity of the medieval formula, this may not be clear to many modern people-----

In the early 80s of the last century, the Japanese Chess Academy organized people to compile a large-scale Go reference book, which was the famous "Daquan" series, which included four books: "Layout Daquan", "Stereotype", "Dead and Alive" and "Tesuji Daquan".

Li Xiangping personally believes that this set of "Daquan" series can be regarded as a great contribution made by the Japanese to Go. Because don't people often talk about "technology accumulation"? And this set of "Daquan" is actually the work done by the Japanese in this regard, and they try to make a summary of the development of Go technology in the past.

This kind of trying attitude is commendable, but what about the effect of summarizing? To be honest, in Li Xiangping's view, the effect of the Japanese work is only reflected in the popularization of Go, and as for what is said to "promote the progress and improvement of Go technology", there is no effect in this regard.

Taking the most representative "Formula" of these 4 "Daquan" as an example, after the emergence of Go AI in later generations, everyone used Go AI to review this "Daquan of Formulas", so humans were a little embarrassed to find that more than 80% of the formulas summarized by humans were problematic in the eyes of Go AI. Well, to put it mildly, it's called "debatable".

In addition to this embarrassment, there is another problem with this "set formula" issued by the Japanese, that is, the summary is not comprehensive, so thick a "set style", "small set style" occupies the vast majority of the space, and it is supposed to have the same status as the "small set style" The "star set style" is not only very small in this "big book", but also the changes listed are relatively simple.

It can be said that it is precisely under the influence of this "Daquan" (because since then, the entire Go world has not done similar work, whether it is China, Japan, or South Korea, in fact, no similar summary work has been done), which gives a false impression to the young people who learn chess in later generations, and everyone generally believes that the "small eye formula" is more complicated than the "star style", mentioning the "big avalanche", "big oblique", "Muramasa demon knife" These famous "small eye formulas" are all the way, but little is known about the "star style".

However, is the "star set" really simpler than the "small eye set"? This is of course impossible. In fact, due to the position attributes of "small eye" and "star position", everyone often says that "small eye" is both offensive and defensive, and "star position" is difficult to attack and difficult to defend.

How complex is the large "star fixation"? The story of "Jinjinglan" must be known to many chess fans, in the early years of the Republic of China, when the domestic first-class player Wang Yunfeng played against the Japanese chess player Heijiro Hirose Liuduan, because Wang Yunfeng had been frustrated many times before, he found a chess book in a hurry, and this book was nothing else, and it was just a "three-son spectrum" written by Bai Ling.

However, it was precisely this book that saved Lao Wang's life, because he learned a formula through this book, and this formula is nothing else, that is, the very ancient and very ordinary "Jinjing Column" in medieval chess, how old is this formula? Ancient to the time of the Northern and Southern Dynasties in our country, this formula has actually been formed, about 500 A.D., Emperor Xiao Yan of Liang Wu has the saying of "East Chamber", which shows that the chess style spread early.

How common is it? Ordinary to the point that Bai Ling only included it in the "Three Sons", and ----- "Three Sons" may not be very clear to some people, this is actually an ancient Go textbook, which is what Guo Bailing thinks he should master if he lets the three sons.

However, it is such a very ancient and very ordinary "Jinjinglan", but it has become a flying knife in the hands of Lao Wang, he relied on this flying knife, leaving a good story of "asking Qiu Weng about the quick things in his life, Jinjinglan is better than the one-eyed dragon". Lao Wang's name is "Qiu Weng", and Hirose has a blind eye, so it is said that the one-eyed dragon, in all fairness, this poem does seem to be a little unkind, but it is precisely because of this poem that the "Jinjing Column" style is famous.

Now the question arises, what level is it in Medieval chess with a fixed form like "Jinjing Column"? Is it one of the most complicated formulas?

Well, in modern times, there are many people who think that this is one of the most complex formulas of medieval chess, and put it alongside the "inverted weeping lotus" and "big pressure beam", which is delicious This is the three complex formulas of medieval chess, comparable to the "big avalanche" and other three large small rules.

However, it is a pity that this may only be the opinion of modern people, but the chess players in the ancient chess system do not see it this way, otherwise, the "Jinjing Column" would not only enter the old "three sub scores", let alone "pair scores", even the "two sub scores" are not eligible to enter.

Speaking of which, there may be many people who don't believe it, but Li Xiangping personally believes that this is precisely where many modern people underestimate the ancient chess.

Why can "Jinjinglan" only enter the "Three Sub-Spectrum"? Li Xiangping's personal understanding is like this: everyone knows that in the field of Go, there is a saying that "judgment is higher than calculation", which means that everyone generally believes that abstract judgment in Go is more difficult than concrete calculation.

For such a concept, Li Xiangping believes that modern people generally have no objections, right? Well, Li Xiangping can ask the modern derogatories to think about it, since modern people will hold this concept, then why do you think that the ancients would not think like this, they will only be obsessed with local tesuji?

So to be honest, as long as modern people are not too self-righteous and feel good about themselves, and do not look at medieval chess with colored glasses, it should be easy to understand that people like "Jinjing Column" can only enter the "three-son spectrum".

Because although this kind of formula is complex and difficult to solve, it is only complex in specific means and tesuji, but it is not difficult in abstract judgment, so in the eyes of the ancients, such as "Jinjing Column" is obviously not up to the highest level, but there are many more complex formulas than this.

For example, Lao Shi's popular "five or six flying attacks" and "dismantling two flying attacks" in that era were high-level formulas that paid equal attention to concrete means and abstract judgments.

Another example is the popular "big iron net", "small iron net", "empty flower corner", "jade screen" and so on in the late Ming and early Qing dynasties, which are also higher levels than the "Jinjing Column".

For example, Li Xiangping's "Iron Heavy Pass" sacrificed today, this is actually also the existence of surpassing the "Jinjing Column".

Okay, let's get back to business, the reason why Li Xiangping sacrificed an ancient high-level formula today, his ideas naturally have nothing unspeakable, and his game ideas today are of course the same as Lao Wang back then.

In the face of an opponent who is stronger than himself and has deeper skills than himself, then choose a more complex, more advanced, and most importantly the opponent is likely to be unfamiliar with the changes to start, and expect such a start to play the effect of "flying knives", which is of course a very common game strategy, which is the most common game strategy used to impact the start.

Therefore, from this point of view, Li Xiangping thinks that his attitude towards today's game is quite correct, and when facing Chang Hao, he puts himself in the "start" position.

However, what Li Xiangping didn't expect was that he personally thought that he was in a good position, but others didn't see it that way.

For example, before half past 10 o'clock in the morning, shortly after the game began, after seeing the "iron heavy pass" on the chessboard, the old coach of Shencheng who knew this change just now said:

"Oh, it seems that Li Xiangping attaches great importance to this game today, I guess Xiao Chang may have trouble today."

"Huh? Why do you keep saying that? ”

"Hehe, I usually pay a lot of attention to Xiangping, this kid, you can think about it, although Li Xiangping is known as a hidden weapon, his novices in the game are endless, but in addition to the earlier online games, as well as the novices in international competitions, have you ever seen him play like this in the Weijia arena?"

The old coach's words reminded everyone:

"Oh, it seems to be really ho, I recall, Li Xiangping doesn't seem to be a novice in the armor arena. That he is today"

After someone opened this head, everyone's brains came out one after another:

"By the way, after playing this game of chess, Li Xiangping is about to go to Japan to compete with Liu Chonghe for the Fujitsu Cup.

"Hehe, there must be a meaning for military training, but I don't see it like sharpening a knife, until I know how fast the information is spreading now, Li Xiangping is a novice today, then maybe Liu Chonghe will know it at night, if I prepare a flying knife, then how can I sacrifice it now."

"Maybe he's not sure about this knife yet, so he wants to try the effect first."

"Yes, yes, yes, there is also a possibility"

"No, no, you can think about it carefully, Li Xiangping's flying knife, that is the real Xiao Li flying knife, his flying knife shot, has anyone seen who dodged it? I'm afraid not, anyway, no one has avoided it so far, this is a real case, so to say that he is not sure to try the effect on Xiao Chang first, whether you believe it or not, I don't believe it anyway"

After everyone talked so much, in the end, the old coach concluded:

"In short, in today's game of chess, I think Xiao Chang still has to have a correct attitude, otherwise he may lose this point and a half."

"Yes, yes, correct attitude, Xiaochang really has to correct attitude"

In the game room, Chang Hao's attitude was really correct, and after seeing Li Xiangping's novice, he began to take a long test with a cautious expression.

And just like that, a game with a good attitude officially began.
