In the penultimate round of Weijia, Li Xiangping, who has recently won a few games of chess in a row, is full of ambition and confidence, and he thinks that he can break his wrist with a first-class master, but he was poured a basin of cold water in the game with Gu Dali. Not only did he lose this game of chess, but he basically lost the whole game, not to mention that he basically had no decent chance, especially in terms of strength, which was completely suppressed by Gu Dali.

After the loss, Li Xiangping was depressed, because after this game, he not only deeply felt the gap between himself and the first-class chess players, but also because he lost this game, his team also lost to the Yamashiro team with a score of 1-3.

Because they didn't get a point in this round, then in this way, the whole team is on the verge of relegation again, and they are currently ranked second from the bottom of all 12 teams in the Wai Li, and with the last round of the game left, it can be said that they have one foot in the Wei B.

After the game, Li Xiangping was silent for a long time.

But fortunately, after looking at the current points ranking and the final round of matchups, Li Xiangping found that there is finally no endless road, and if the last round is played well, their team still has hope of relegation.

Because in the last round of the game, they happened to meet the current third-to-last Pingmei team----- this is a real relegation battle, and it is the kind of relegation battle that does not need to look at the faces of other teams.

This year's relegation situation is like this: in addition to the last place that has been relegated, another relegated team will be produced between them, and so far, the Pingmei team is only one point more than Li Xiangping's team.

Seeing such a point situation, Li Xiangping suddenly felt a lot of pressure.

You must know that the competition system of Weijia is different from many other competitive events, there is a special "home will win" rule, that is, two teams 4 games, if it is 4 to 0 or 3 to 1, then the winner will get 3 points, and the loser will get 0 points.

If the two teams are tied 2-2, it depends on which side of the home team wins, and the side that wins gets 2 points, and the side that wins gets 1 point.

It is precisely because of such a rule that it is completely conceivable how important Li Xiangping's game is in the final round. It is no exaggeration to say that if Li Xiangping loses in the last round, then his team has a probability of more than 80% relegation, and if Li Xiangping wins, they have more than 50% hope to succeed in relegation.

After the penultimate round of tournaments, it's September 2002, and after that month, international competitions are still busy, and most of the tournaments are getting better.

For example, at the beginning of this month, Li Xiangping will go to Japan to participate in the quarterfinals of the "Toyota Cup", in the middle of the month, the quarterfinals of the "LC Cup", and at the end of the month and the beginning of October, the quarterfinals of the "Samsung Cup" and the semifinals of the "Toyota Cup" will be played in succession. Although there are so many important competitions, before going to Japan to participate in the "Toyota Cup", Li Xiangping is still thinking about the last round of the armor competition.

Because this game is the last round, and the closing ceremony is after the competition, the game time was postponed to late September, and it was precisely because there was still sufficient preparation time that Li Xiangping pulled down his face and asked his plug-in for advice, asking him if there was any good way to quickly improve his ability to calculate the road.

However, what Li Xiangping didn't expect was that when he opened his mouth to his plug-in, Lao Shi replied to him like this:

"Counting the way? I think Xiangping Xiaoyou's ability to calculate the road is very good, and there is no need to use other special methods to improve. ”

Well, what do you want to say about Lao Shi's words, if it was Li Xiangping a year ago or half a year ago, then he would definitely be complacent when he heard this, and he might even be fluttering. However, now he is different, especially when he has just been taught by Gu Dali to be a man, which makes him realize his lack of ability to calculate the road, then he is even more dissatisfied with Lao Shi's answer, and feels that his plug-in is obviously perfunctory.

Li Xiangping said to himself with a dark face: "Brother Ding'an is going to be perfunctory, you have also seen this game, my way of calculation is not bad?" I don't think I deserve to be able to do this, do I? ”

"This"

How to say it, after all, the two have been getting along for several years, so of course Shi Da Qisheng also heard it, Li Xiangping seemed to be real this time, so he paused a little and decided to seriously discuss this issue with Li Xiangping:

"In this way, Xiangping Xiaoyou, since you talked about the way of Go, then let me ask you first, in your opinion, what is the way of Go?"

"This"

This time it was Li Xiangping's turn to choke, don't look at him talking about calculating roads and calculating roads every day, but if you really want him to give an accurate definition of this word, then he really doesn't have that ability.

After thinking about it for a while, Li Xiangping replied: "This and this, I thought that the calculation of Go was more complicated, this is actually a complex, which can be divided into two kinds of real calculation and virtual calculation of the road Alas, I don't know how to say it, anyway, I personally think that the kind of what can count how many steps at a time, the so-called "counting a thousand hands" person may not be able to say that he has a strong ability to calculate the road. ”

"However, I very much agree with Xiangping Xiaoyou's statement, as you just said, there is a distinction between virtual and real in the calculation of the road of Go, and the so-called calculation of a thousand hands is just a kind of real calculation road, and in Go, the real calculation road is only the foundation, and the virtual calculation road is more important, especially in high-level duels, it is often the virtual calculation road of the chess player that plays a decisive role."

Li Xiangping nodded when he heard this, and he still agreed with Lao Shi's words. Regarding the "virtual calculation road" in Go, Li Xiangping personally understands it as the kind of "calculation path with judgment", as for why this kind of calculation is more important? In fact, not long ago, Lao Shi won the game of chess against Liu Chonghe in the final of the "Fujitsu Cup", which may be a better illustration of this problem.

In that game of chess, Liu Chonghe mainly lost in two places, one was the "sharp rush" in the front, and then the "killing" method behind Lao Shi.

In the later offensive and defensive battles, will Liu Chonghe's ability to "calculate the road" be worse than Lao Shi's? Objectively speaking, of course, there is no, such as the specific means that can contact his base camp later, Liu Chonghe has actually calculated it.

The only thing he didn't calculate at the time was that after his big dragon escaped, the situation was still backward, no, judging from his next few moves, he didn't fail to calculate, he just calculated a little late. However, it was such a small gap that led to the slaughter of the big dragon in his game of chess, and it ended in such a tragic way.

Of course, when we say "he didn't calculate" here, in fact, a more accurate description should be to say "he didn't judge when calculating specific means", "he didn't judge", and this kind of calculation with judgment is what everyone often calls "virtual calculation road".

If you really want to talk about it, in fact, "not judging" is nothing, after all, in a game you "don't judge", that only affects the game, the real scary thing is that you judge when you calculate, but you "misjudge", or simply "can't judge", which is often the culprit of losing.

Don't think that professional chess players will not make mistakes, in fact, in Li Xiangping's view, it is also normal for professional chess players to make mistakes in judgment.

When Mr. Wu Qingyuan was competing with Japanese chess players for Juban, he played a total of 10 Juban chess in 20 years, and among them, there was an old man who played the most with him, a total of 3 times, but this old man finally lost badly, and was finally beaten by Mr. Wu to "Dingxian" This old man is the first Japanese to play nine dan through the game, Mr. Fujisawa Tomosai.

Don't think that Mr. Fujisawa Tomosai is a rookie, in fact, his level is extremely high, especially his strength, which is even Sakata Eio, and his nickname is "Dump Machine", so it can be seen from this nickname that he was famous in the entire Japanese chess world for his strength and calculation at that time.

So why didn't he win Mr. Wu Qingyuan? In Li Xiangping's memory, there is such a clip of the game that year, which may be very revealing.

When Fujisawa Tomosai played Shiban chess with Mr. Wu for the second time, there was a game in which Fujisawa Tomosai made a super strong move in the middle game, which caused many masters to marvel at the game, thinking that the chess hand was far-reaching and fully worthy of the title of "counting a thousand hands". Not only that, but Fujisawa Tomosai's series of moves after that super move are even more exquisite, and after N rounds, Fujisawa Tomosai's strategic goals and strategic intentions seem to have been fully realized.

But just as everyone was ready to cheer for Fujisawa Tomosai, a low-level chess player who was serving as the notator of the game at the time weakly said:

"How do I think, Mr. Wu's real space seems to be a lot ahead"

This is the gap between Mr. Fujisawa and Mr. Wu Qingyuan.

This is actually the difference between the "real calculation path" and the "virtual calculation road" in Go.

Li Xiangping even believes that after Go reaches the professional level, the level of distinguishing professional chess players is largely reflected in the virtual calculation road (of course, in the case of Lao Nie, the ability to calculate the virtual road is still there, but the actual calculation path has completely abolished the martial arts of chess players to be excluded).

And Li Xiangping thinks that this point of view, in fact, after the birth of the later generation of Go AI, it is more obvious, where is the gap between humans and machines? In later generations, everyone recognized that the biggest gap is actually the difference in judgment, that is, the difference in the "virtual calculation road", but from the perspective of the "real calculation road", the gap between humans and Go AI is not so big.

After reading those dog moves that embody the "virtual calculation road" of Go AI, sometimes I will feel that the previous level of judgment of human beings is simply childish and ridiculous.

It can be said that it is precisely because Li Xiangping has seen the dog tricks of later generations that he is so eager to improve his level of calculating the road, especially the level of the virtual arithmetic road.

However, what Li Xiangping didn't expect was that when he asked Lao Shi for advice on this issue again, Lao Shi actually said the same thing.

Shi Daqisheng smiled at Li Xiangping and said:

"Little friend Xiangping, you don't have to think of any special way now, you need to know that you are on the right path."

"Huh?"
