Approaching 2 o'clock in the afternoon, when Li Xiangping saw Lao Shi fall into the 75th hand of the overall ...... Well, a more accurate description: When Li Xiangping heard the instructions from his plug-in, he found the point on the chessboard according to this instruction, and at that moment, Li Xiangping had a feeling of sudden enlightenment, and he immediately understood what Lao Shi meant.

It's a good move! It's a good game that really "has both offense and defense"!

On the surface, this move seems to be just the "own hand" of that kind of defense-----

Before this move, Lao Zhao was attacking a big dragon in black chess, of course, Lao Zhao's attack was not for the purpose of slaying the dragon, but to take the opportunity to consolidate his newly established basic void, so it can be regarded as a kind of "attack profit". And Lao Shi's 75th move, it is precisely to resist the opponent's attack.

If this move has only one function, then in Go, such a move is called a "home move".

It's a pity that Lao Shi's move is not a simple "own move", Li Xiangping saw it at the first time-----

Yes, Li Xiangping did see it at the first time!

Because before Lao Shi reported this chess move, Li Xiangping himself also thought about a point, precisely because he ... It didn't seem to be able to think of it with his own plug-in, so he could quickly feel the wonder of Lao Shi's move.

Well, if the move that Li Xiangping thought of himself was the "own move", a move that was purely defensive, then Lao Shi's move was not, this move did not forget to attack, and hid a very severe follow-up move-----

If there is a chance to cash in on this follow-up move, then black will be able to penetrate the basic void that white has just rebuilt.

Li Xiangping's sudden enlightenment is in this place.

He just questioned Lao Shi's play, thinking that the situation of black chess has been unfavorable since the 37th move, so isn't it because white can re-establish a basic blank piece?

What if this basic void could be broken through again?

Or simply say: because of the existence of the 75th move, Shenma's "white chess re-establishes the basic void" does not exist at all, which is actually a false proposition, so the previous 37th move, can you still think that it is a bad move?

The obvious answer is that if this is the case, then the previous move is certainly not a bad move.

Not only is it not a bad move, but it can even be seen as a good move to break the gap harshly!

"It's really strange, Lao Shi, how did this guy think of playing that chess hand at that time? It doesn't make any sense......"

After figuring out the technical problems, Li Xiangping soon had new questions. This question is: How did you think of Black 37 at that time?

In Li Xiangping's opinion, this question is very interesting, not only interesting, but even for himself, this question is also very important, because if you want to better cultivate the "combination of two swords" with Lao Shi, it is very important to figure out such a problem.

It's just that Li Xiangping couldn't figure it out all of a sudden, and he couldn't guess how he thought of that hand at all.

First of all, Li Xiangping can make it clear: Lao Shi's 75th hand just now is definitely not the product of some "inspiration", nor is it a wonderful move he came up with temporarily.

On the surface of all kinds of signs, from Lao Shi's voice and tone, Li Xiangping knew that he had already reached this point, and he could be very sure that this was his own premeditated plan.

It is precisely because he knew that this was premeditated by Lao Shi, so Li Xiangping was even more puzzled: So how did Lao Shi think of this step in the first place, the starting point of the entire battle plan, that is, the 37th move of today's game?

You must know that this is not a simple problem of calculating the path, if it is a simple calculating the way problem, then it is nothing, from 37 hands to 75 hands, this is just a way of calculating more than 30 moves.

In the words of Mr. Eio Sakata, a famous Japanese chess player: the calculation path of a professional chess player should be "30 moves at a glance", and if it is measured by this standard, then today's straight line calculation is only a little more than "a glance".

The real problem today is that Lao Shi seems to have no reason to think of the 37th hand before.

Because Lao Shi is not a Go AI, he doesn't know what "deep learning" is, let alone "Monte Carlo Teaching", Li Xiangping knows very clearly that his plug-in still has a human soul.

It is precisely because he is still a "person" that Li Xiangping is strange, he should have no reason to think of that hand.

Let's take Li Xiangping himself as an example, because he is not the kind of "weasel that drills the ground" type of chess style, and he usually doesn't like the "ditch flow" play, so when he is in the game, he first instinctively rejects the black 37 play.

In the vast majority of the time, a move like this flashes through his mind at most, and he rarely verifies the feasibility of this move.

Even in some irresponsible online games, Li Xiangping may use this kind of play, but he will never be so deep and will calculate whether there are any good moves after more than 30 moves.

Li Xiangping knows that in this regard, he is the same kind of person as himself, Lao Shi is a famous chess master, and he even pays more attention to chess theory than himself.

However, today, he actually chose a seemingly completely unreasonable move early.

Regardless of the choice of this play, he actually seemed to have premeditated, and he calculated so deeply at such an early stage, calculating more than 30 moves.

Is this possible? Is this reasonable?

Well, now the first question no longer exists, because now that Lao Shi has come out, then there is no discussion of the impossible question.

Now ask one: Is this reasonable?

Li Xiangping didn't understand, he couldn't figure it out.

It was precisely because he couldn't figure it out that he desperately wanted to know the answer.

"Well, it's better to end this game of chess quickly, so that I can quickly ask Lao Shi ......"

In fact, Li Xiangping was not disappointed, this game of chess did end quickly, and even in Li Xiangping's view, when Lao Shi's 75th move came out, the essence of this game of chess was exhausted, and there was basically no suspense-----

No, it may still be a bit too exaggerated to say this, in fact, after 75 moves, this game is still in suspense, but there is a premise, and this premise is: Mr. Zhao Zhixun must be the same as Li Xiangping, he must pay attention to the hidden and strict follow-up measures at the first time, so that the situation may still be maintained.

However, it is a pity that Mr. Zhao Zhixun does not seem to notice this, and he may still regard this move as his "own move".

So at around 3:40 p.m., just over 100 moves, the game came to an abrupt end when black cashed in on the hidden way to break the air.

After the opponent confirmed to admit defeat, Li Xiangping couldn't care about anything else, and he asked Lao Shi as soon as possible:

"Quick, Brother Ding'an, tell me quickly, how did you come up with that hand at that time?"
