The "man-machine war" that Mr. Zhao Zhixun just mentioned was a man-machine confrontation held by Japan in real history, half a year after the "alpha dog" defeated Lee Sedol, and Zhao Zhixun challenged a "Japanese dog" named ZEN.

It's just a pity that in the "man-machine war" held by the Japanese, although Mr. Zhao Zhixun won in the end, he defeated the Japanese dog with a score of 2 to 1, but later did not form enough influence, not only failed to save the dignity of human beings, but even most people did not admit that this was a real man-machine war.

It's not for other reasons, because the strength of the Japanese dog at that time was really not good, and there were still a lot of technical flaws, which were manifested in the game that the loopholes were very obvious, which did not represent the development level of Go AI at that time.

In fact, if you really want to talk about it, before the "Alpha Dog" was born, the Japanese dog named "ZEN" was already well-known in the Go world, and it is said that it has broken through the four sub-levels of human beings, and is the undisputed boss of all the "primitive dogs" in the early years.

However, to paraphrase the pretending words of the astronaut of the lighthouse country who landed on the moon that year: his own small step is a big leap for the entire human race.

This sentence is changed to this place, and that is: from "ZEN" to "Alpha Dog", this may be just a small step for human computer technology, but it is a big step for Go technology.

A game-changing step!

In hindsight, the man-machine war launched by the Japanese obviously seemed a bit rushed, "ZEN" was originally just a primitive dog, although the Google paper had come out at that time, and the developers of "ZEN" also upgraded the dog, and quickly improved its level in a very short time.

However, at the time, "ZEN" was not a truly mature dog, and at best was just an "enhanced version of the original dog".

At 1 o'clock in the afternoon, Li Xiangping re-entered the game room, and while reviewing the man-machine battle, he was thinking about how to play chess in the afternoon-------

The reason why he chose to go down like this today and suddenly sacrifice the "cosmic flow" that he basically didn't use before was, of course, affected by the man-machine war.

Of course, the "influence" mentioned here does not mean that Li Xiangping was influenced by "ZEN", but more by Mr. Zhao Zhixun.

Li Xiangping doesn't know much about AI, but as a chess player, he is still deeply impressed by the process and pattern of the three games of chess that year.

Because of the three games of chess back then, the pattern formed in the middle of the game was almost identical: Mr. Zhao Zhixun's board was his "ground-drilling weasel" like extreme realism, and "ZEN" was like a cosmic flow.

"ZEN" used the cosmic flow and finally lost to Mr. Cho Ji-hoon, which is something that Lee Xiang-ping already knows, so if he adopts the cosmic flow, can he defeat Mr. Cho Ji-hoon? This is what Li Xiangping wants to try today-------

It's hard to understand what kind of psychology Li Xiangping is now, "ZEN" is obviously losing, why do you want to learn it?

In fact, to be honest, even Li Xiangping himself doesn't know why, there is really no other reason, he just wants to try it today, as if he has an inexplicable urge to make a "cosmic flow".

After returning to the game room, since the last hand of the morning was the 46th in the world, it was the turn of Mr. Zhao Zhixun, who was in charge of black, to fall next.

However, he did not fall immediately, and within 10 minutes after returning to the game room, Lao Zhao was not in a hurry to fall.

While waiting for his opponent to fall, Li Xiangping suddenly regretted a little, he felt that his strategic choice today may be really a little unwise, especially when he saw his opponent's 47th move, this regret was even worse-------

Lao Zhao's hand is not a particularly good move, nor is it that as soon as this move comes out, Li Xiangping immediately feels that his situation is unfavorable.

It can even be said that Lao Zhao's move was completely expected by Li Xiangping------- because this is a move with a strong Zhao Zhixun's personal style, the kind of "weasel that drills the ground".

As soon as this move is played, the pattern of this game is fully formed, and it is an almost irreversible pattern.

This is the kind of confrontation pattern in which black is extremely realism versus white.

Li Xiangping does not regret this pattern, what he is worried about is actually this 'extreme' --------

As for why worry? Of course, chess players with amateur early stage strength know that once such an extreme pattern is formed on the chessboard, it will look very exciting on the surface, but the later play will become very simple and rude, basically using attacks and treatment to determine the victory or defeat.

If black successfully breaks through the big appearance of white chess, it is basically black winning.

Otherwise, white wins.

So the question is, who would prefer this pattern if the two players were divided into "top" and "bottom" in a professional game?

The answer is very simple, of course, as the "starter" side, this pattern is more welcome, because under this extreme pattern, there are too many things that do not need to be considered at all, and everyone is limited to competing in the same field, so as to virtually eliminate some other gaps between the two sides.

Specific to today's game of chess, compared with the current Mr. Zhao Zhixun, who is the "starter" and who is the "starter"?

Li Xiangping doesn't need to be hypocritically modest, he thinks that of course he can only be considered "hands-on" now, not to mention that Mr. Zhao Zhixun is now nearly 50 years old, even if it is his peak more than ten years ago, because he has mastered some more advanced dog tricks, he should be counted as a master.

But today, isn't it a bit unwise to adopt a more favorable method for "starting"?

It's just that there is no regret medicine in the world, and since this pattern has been formed, it is impossible to go back, and Li Xiangping can only think about how to win this game of chess now.

“........ Alas, it's better to hope you don't use the two swords......."

With this in mind, Li Xiangping put aside other distractions and began to wrestle with his opponent on the chessboard.

After about an hour, when Li Xiangping saw his opponent's latest move, his brows furrowed even tighter-------

This is the 69th move of the whole world, and to be honest, this move is still in Li Xiangping's calculation, but it is the last move he wants to see.

This is a move similar to a "depth charge", and as soon as this move is played, the already extreme pattern becomes even more extreme.

is so extreme that the dragon slaughters to determine the winner, Li Xiangping seems to have to kill this depth charge-like chess piece to be enough to compete with the opponent.

After Mr. Zhao Zhixun dropped this chess move, Li Xiangping subconsciously reached out to help the chess piece, can he kill this chess piece? Since he hadn't had time to make a detailed calculation, Li Xiangping was not clear for the time being, but based on his intuition, he thought he couldn't kill it-------

And the source of his intuition is very simple, since he has also thought about how his opponent will play (although this is not the only way Li Xiangping predicted), he still thinks that it may be very difficult to kill chess.

However, no matter how difficult it is, it seems that you have to give it a try, because once this chess piece is escaped by the opponent, the big appearance of the white chess piece is almost gone, and no matter how you look at it, it is not enough to look at the field, so Li Xiangping must give it a try.

After completing the inevitable exchange of a few moves, Li Xiangping began to think deeply about the possibility of killing this chess piece.

However, it is a pity, or a little funny, in the next thought, Li Xiangping did not find a way to slay the dragon, but helped the opponent find a way to cure the orphan-------

This is that kind of dilemma, it is difficult for white to kill the dragon, and it is also a bit difficult for black to successfully control the orphan, such as the method of controlling the orphan that Li Xiangping just discovered, which is also a very hidden and very difficult to find method, but unfortunately for Li Xiangping, as long as this means exists, then the dragon slaying route designed by himself will not be established.

Li Xiangping began to rethink, trying to find another route to slay the dragon, but unfortunately, nearly half an hour had passed, and he had not been able to find a completely capable way of slaying the dragon.

The time gradually came to 3 o'clock in the afternoon, seeing that all the roads seemed to be impassable, Li Xiangping finally ran out of options, and he smiled bitterly and asked for help from his plug-in:

"Brother Ding'an, what do you think I should do now?"

"I'm sorry Xiangping Xiaoyou, I haven't found a good solution for this situation, or you can try it somewhere and somewhere......."

After listening to Lao Shi's suggestion, Li Xiangping smiled bitterly at that time.

Well, if there is really no other way, then the method recommended by Lao Shi is really a good strategy:

First: If this way of playing is carried out, the dragon slaying will definitely not be established, but if it continues to evolve according to this path, then after dozens of moves, the situation of white seems to be maintained.

In other words, the method recommended by Lao Shi can minimize the loss, and the success of being orphaned by others will certainly lead to the backwardness of the situation, but there seems to be a chance to maneuver later.

The second and more important point: the covert method of treating orphans that Li Xiangping himself discovered just now is actually included in this change.

What he just said about "dragon slaying is definitely not valid" is based on the fact that Mr. Zhao Zhixun can completely get right, but what if he doesn't find that hidden method of controlling orphans?

If he really can't find another way, then he can only do it like this, but after listening to Lao Shi's words, Li Xiangping is still a little unwilling, and he decided to think about it again.

After all, the opponent is a veteran who is nearly 50 years old, so in the face of such an opponent, do you still have to expect the opponent to make mistakes in the game?

Besides, since Lao Shi said that he didn't find a better way to play, can't he find it.......

It is the psychology of comparing it with his own plug-in, and seeing that it is only a little more than 3 o'clock now, and there is still a lot of game time, which prompted Li Xiangping to try again.

After another 10 minutes or so, Li Xiangping finally found a clue, or a new fulcrum of thinking.

This fulcrum is nothing else, it is the hidden means of controlling orphans------- since it is because of the existence of this means, the entire dragon slaying plan is not established, if this method can be broken in advance, isn't it possible to be established?

Li Xiangping's thinking began to diverge, and he began to look at this local problem from a higher perspective.

Another 20 minutes passed, and a smile hung on the corner of Li Xiangping's mouth, because by this time, a new plan had taken shape in his mind.

Li Xiangping didn't rush to make a move immediately, he spent about 5 minutes to verify that his calculation was correct, and then he picked up a white piece and slapped the chess piece on the chessboard.

"Oh, Xiangping little friend! You're ........."

Hearing Lao Shi's sudden voice, he didn't know why, Li Xiangping was inexplicably happy at this moment, because he could hear from this sound that his plug-in really didn't seem to have changed yet.

At least at this moment, Shi Da Qisheng should not have counted the new changes he discovered.

Of course, Li Xiangping doesn't have time to explain to him now, anyway, after this chess move, there are not many changes in the next 10 rounds, and it is close to the change of "one way".

And when this "one way" is over, his intentions will be revealed to the world immediately.

And Lao Shi exclaimed, the opponent Lao Zhao did not doubt it at this time, after all, Li Xiangping's true intention was to hide behind nearly 20 moves, so in the face of a seemingly ordinary and close to the "one way" imperative method, most people will not doubt it.

The pace of the two sides suddenly accelerated, and in less than 10 minutes, more than a dozen chess moves were crackled.

When the time came to about 3:40 p.m., Li Xiangping dropped his latest move, which happened to be the 100th move in the world, and Mr. Zhao Zhixun's hand finally stopped.

And by this time, Li Xiangping finally had time to say a few words to his plug-in:

"Hehe, Brother Ding'an, what do you think of my hand?"

"Ouch this ..... I've told you a long time ago, you and I are really different, this move is whimsical, extremely flexible, and I am ashamed of the talent of Xiangping Xiaoyou. ”

"Haha has won the award, Brother Ding'an has won the award, this trick carving insect has a small skill ear, it should not be praised like this......."

Strictly speaking, Li Xiangping's words are not particularly hypocritical, his move is really not the kind of very cool "big move", and he will not be able to slay the dragon because of this move.

The only function of this move is to bring in another piece of black chess.

Another chess roll that seemed safe but not yet fully alive came in.

However, in today's situation, this move can play this role, and Li Xiangping thinks it is enough.

Because this move has changed the overall pattern of this game of chess, from the original simple and crude life-and-death to the left and right of white, and to the "attack profit" of white.

As soon as this move is played, the piece he just got involved in will inevitably be looted before Black successfully handles his big dragon.

Although the looting that black will receive is actually not much, at best it is about 4 moves, but according to Li Xiangping's own calculations, he judged that this profit was enough.

If you can really make a profit of 4 moves, then this move will not be a black advantage, but Li Xiangping's white will enter the final stage with a slight advantage.

Obviously, this move was not only unexpected by Lao Shi, but also by Lao Zhao's expectations.

So he also started to take long exams.

What will this game of chess look like? The answer will be revealed right away.
