"After research, we believe that White's move just now should not be valid......"

At the scene of the 3rd "Ying's Cup" five-way chess final, a little after 2 o'clock in the afternoon, Li Shifo was explaining the research experience of Koreans on this large-scale routine.

“…… When white is played here, the two sides must form a "duet". On the surface, when white has this method, he can "kill" quickly. But in practice, black has a very stubborn means of resistance. Please take a look at ......"

Next, Li Shifo quickly changed his chess on the chessboard. As you can tell from the speed of his moves, he is also very familiar with this change.

“…… Black's move can be called a "cold" move, and sometimes it's really hard to think of. Because the only function of this move is to ensure that this "all the way to the pull" is the first move. But in today's specific situation, this step is fatal. One "all the way to the pull" here, and one "all the way to the pull" there, with these two "all the way pulls", this has already made black grow a breath, so this large kill, it should be a slow move for white......"

Li Shifo didn't say much, and he didn't continue to talk about it here. However, through his explanation and chess arrangement, at least chess players of Zhang Da's level have clearly seen the changes here.

"Two pulls along the way", this is a problem that can often be encountered when killing. Such a problem may sometimes be ignored by amateur Go enthusiasts below 3 dan level, but at the level of reporter Zhang Da, there is no problem at all to understand.

It is precisely because most people in the research room have understood that the hearts of reporter Zhang Da and others began to sink, including Chen Chaoyue, Nie Whirlwind, Team Leader Hua and others, and none of them looked good. South Korea's Park reporter and others began to be overjoyed.

"Is this the end of the game? Is the final of the "Ying's Cup" still going to usher in the final tiebreaker? ”

This is at this moment. Almost everyone in the research room thinks.

Indeed, Li Shifo's explanation just now was very convincing, and he even found a good reason for Li Xiaoqiang's "mistake". Why did Li Xiaoqiang make a mistake? Of course, it can't be said that Li Xiaoqiang doesn't know the truth of "two pulls and two delays all the way", but he didn't notice that the step was "cold". This may be the key - it is not uncommon to study a large routine, even if it is a group study.

It's okay if you haven't studied it that thoroughly. The most important thing is that the mistake made by Li Xiaoqiang is still the most serious kind in Go. It's a big killing. What does it mean to have a big kill? It means that Li Xiaoqiang has no room for maneuver at all.

"This game of chess...... Is that really the case......

From 2 o'clock in the afternoon to 2:30 o'clock, a vigorous secondary study was carried out in the laboratory. That's right, although the hearts of Nie Whirlwind, Zhang Da, reporters and others have sunk to the bottom. But it's definitely a little unrelenting, isn't it? What's more, for such large-scale and complex changes, it is also necessary to continue to study in depth.

So did Li Xiaoqiang really make a mistake just now? Of course not! In this large-scale routine, Li Xiaoqiang not only knew that step was "cold", but he also knew more than Li Shifo. However, by the time the on-site research laboratory discovered the problem, it took everyone about half an hour.

Interestingly. The first to discover the problem in the on-site research room is still the Korean chess player.

While the Chinese are conducting secondary research, the South Koreans are also conducting secondary research. However, this time, the keynote speaker was replaced by Cao Yanzi, who combined the game of chess he had lost to Yoo Chang-hyuk to show reporter Park a change in this large-scale routine. Li Shifo added on the side.

“…… So, do you think Chang Hyuk has won this game......

"Of course......" Cao Yanzi smiled heartily at this time: "...... Although Li Xiaoqiang is called a chessboard wizard, no matter how powerful his witchcraft is, I am afraid that he will be in a catastrophe today. So be it. In order to make it easier for you to see, let's take a few more breaths. Just take a few more steps and I think you should be able to see it clearly. ”

When Lao Cao was playing chess, Li Shifo was smiling and watching from the side. Li Shifo is an honest child, but he is also a strict person. He saw the record of reporter Park brushing up on the side -- he knew in his heart that reporter Park was going to post the reference map of Cao Yanzi in the magazine.

So at this time, Li Shifo decided to correct a small mistake of Lao Cao:

"Master. You are not in the right order, you can play a game that is so tight, but not today, because today's black chess is not good......"

The sign is not good!

The plate that Lao Cao and Liu Changhe played, Lao Cao went down is "star." Xiaomu", and Li Xiaoqiang's game today, he is "Erlian Star". The difference between "Star Position" and "Small Eye" all the way. But Go is so interesting, and sometimes it's just such a difference that the whole game will change dramatically.

For example, today's game of chess!

The first to notice the abnormality was Cao Yanzi:

"The sign is not good? This and this...... I really didn't notice that...... No, no, no, I don't think there are other variables in this game. ”

"There are no other variables, the killing here actually has nothing to do with Zhengzi. If you kill against each other, white can't win at all, and black just needs to change places and tighten up first...... Just ......"

When Li Shifo said this, he finally noticed something unusual, so he finally didn't say the word "line".

Cao Yanzi's feeling is correct, and what Li Shifo said is also right, although this pair of kills does not have anything to do with Zhengzi, in this part, no matter how white kills, black chess cannot be killed. However, due to the different order of tension that black needs to choose, this makes the whole game different. Poles apart!

So where is the standard answer to this mega-routine? In addition to Li Xiaoqiang in the game room, now this standard answer is in the China Chess Academy, in the Chinese National Go Junior Team!

Also at about half past two in the afternoon, the Chinese Chess Academy, Gu Dali, Kong Erjie and a group of members of the national junior team were laughing there. Gu Dali said with a grin:

"Qiu Bao is amazing, this change you found has been used by the boss. If the boss relies on this routine to win the world championship. Then be sure to ask him to treat you to a treat. Everyone said yes. But then again, Qiu Bao, you're not kind. Why didn't you tell us about such a perverted change first, but let the boss know first. ”

Gu Dali's group of chess players entered the national junior team, and Li Xiaoqiang was the "Teacher Li" for a short time, but after everyone got acquainted, especially Gu Dali was accepted as a disciple by Lao Nie. Li Xiaoqiang's "Teacher Li" can no longer be done. This guy used the excuse of "seniority" to no longer call him "Teacher Li", but learned from Chang Rensheng and called them "Boss". As for the other members of the national junior team, it is natural to follow the same example. Therefore, if Li Xiaoqiang still thinks about the addiction of "Teacher Li", it is estimated that he will have to wait for several years.

The "Qiu Bao" in Gu Dali's mouth is the famous "Brother Niu" in the "Little Tiger Generation" of Chinese Go, the famous "Bitter Child" and "Bull Demon King", and the most outstanding representative of the "diligent" Chinese Go players.

However, the "Brother Niu" of later generations is still just Qiu Bao in everyone's mouth. "Qiu Bao" listened to Gu Dali's words. He was giggling there:

"I did put this change on the table at the time, but I didn't know much about the gains and losses here. So I consulted the boss at the time......"

"Brother Niu" really didn't deceive Gu Dali. Li Xiaoqiang's changes under the stage of the World Series finals today, the "original" is indeed him. However, this can be regarded as the result of his drilling of the horns of the bull - compared with Gu Dali, Kong Erjie and others, the greatest talent of "Brother Niu" in Go may be his kung fu of drilling the horns of the bull.

Despite this, the tip of this horn of "Brother Niu" is still a bit special. For this big change. In terms of real calculations, it should be said that he has completely figured it out. But the judgment of this change is pros and cons. He was still a little vague at the time - young man, the way of calculation is always ahead of judgment. This is not only him, but also the vast majority of professional chess players. Among them is Li Xiaoqiang.

The same was true of Li Xiaoqiang when he was young.

Now Li Xiaoqiang is not young, so at that time, "Brother Niu" found Li Xiaoqiang and asked him to help him judge and judge. It's as simple as that, Li Xiaoqiang thinks this change is okay. So it was used in today's game......

So what exactly is this change?

At 2:40 p.m., around 80 moves in the game, this large-scale routine came to an end for the time being. However, when it arrived at the laboratory, it was about 2:50 minutes.

3 o'clock in the afternoon. Reporter Zhang Da, Team Leader Hua and others gathered around Nie Whirlwind.

Nie Whirlwind's current calculation may no longer be good, but his judgment is still the world's first-class level. This is something that everyone should recognize. Therefore, it is normal for everyone to wait for him to judge.

Reporter Zhang Da and others stared at Nie Whirlwind, but Nie Whirlwind stared at the chess game for more than 10 minutes.

At 3:10 p.m., although reporter Zhang Da and others were still nervous, their faces were much better than just now.

"Old Nie, what do you think of the changes here? What do you think? Reporter Zhang Da asked nervously.

After a few more minutes, Lao Nie finally raised his head, and he breathed a long sigh of relief:

"I think that after this routine, white should be okay......"

Despite Nie Whirlwind's ability to judge, despite the fact that he was a man of extreme self-confidence - he rarely used an ambiguous tone when he spoke.

However, today, even if he is as confident as him, he does not dare to easily draw conclusions about the results formed on the chessboard, which shows the difficulty of judging the gains and losses here.

"Lao Nie, is it white chess that can still be played, or white chess that is "okay", can you make it clear now? ”

"This ...... I now think that it is "white" can be "......", and after thinking briefly for a while, Nie Whirlwind slightly aggravated his affirmative tone:

"Under this routine, a large piece of white chess is eaten by others, and black chess has made a huge profit, and the number of meshes on this piece of chess has exceeded 60 meshes, so locally, it can be considered that black chess is cheap. However, from the overall point of view, white chess is not without gain, what is the value of this external potential formed by white chess? Now it becomes the key to judgment. I just took a closer look and think that white has at least four advantages to make sure that this external position is enough to compete with black's field......"

When Nie Whirlwind was analyzing the situation, everyone was listening quietly.

Today's game of chess has been played so far, black has gained a huge profit, and white has formed a strong external momentum, which is of course predictable. If Li Xiaoqiang's big dragon was simply killed, then today's game should have ended a long time ago, and Nie Whirlwind would not sit here and talk about it.

How did Li Xiaoqiang's white chess form this external momentum? The most important reason, of course, is related to the "tight order" of black. And the causal relationship in this can be attributed to the previous "difference all the way". This is what Li Shifo and others did not study. This is also the essence of the whole routine today!

Just today, in today's "China-South Korea Routine Competition", where China is smarter than South Korea is that Li Shifo and others only see a part. And Li Xiaoqiang, he sees the overall situation!

Li Xiaoqiang is sure that after this large-scale change, he should benefit slightly. By the time this "big routine" is completed, he is getting closer and closer to his 4th World Championship!

So what are the benefits of this change? Everyone was listening carefully to Nie Whirlwind's analysis.

While Nie Whirlwind was analyzing, the chess game was moving towards the end step by step. (To be continued.) )
