In the game room, Li Xiangping faced Zhang Xu's chess hand, and he began to think about countermeasures, but until he thought of half an hour, half an hour had passed in the afternoon game, and he still couldn't clarify his next move.

This is indeed a very headache choice, Li Xiangping even thinks: In today's pattern, it should belong to the situation that he will not be able to, this may also be his most serious shortcoming, if he can form a breakthrough in this regard, then his strength will be able to go to a higher level immediately.

The "difficulty" of this situation does not mean that Li Xiangping will not be able to find the next hand, on the contrary, there are too many points on the chessboard for Li Xiangping to choose.

However, each of these choices seems to be of great value, so big that Li Xiangping can't tell the specific size of it.

Each of these points represents a different operational idea and a different operational concept, so that Li Xiangping is completely confused about which operational idea is better.

Each of these choices directly affects the future flow of this game of chess, and now Li Xiangping, of course, he can't figure out which flow direction is the best, which is the flow direction that leads directly to the direction of victory.

It is precisely because of the above reasons that Li Xiangping felt very tricky, he hesitated there for more than 20 minutes, and still did not choose his next hand.

However, it is not a problem to continue like this, after all, the game time is limited, and it is only in the prologue stage, if you continue to hesitate like this, it is easy to fall into time panic later.

It was with this in mind that at around 1:35 p.m., Li Xiangping finally fell after making it clear that he would definitely not find the best answer to the current situation.

This move is the 51st move overall.

When Li Xiangping dropped this move, to be honest, he himself couldn't figure out whether his move was good or bad.

The only thing that is clear about Li Xiangping is that the chess he played seems to be in line with the chess theory, and it is in line with the chess theory created by human beings.

This is the only reason why Li Xiangping made this move.

Why does this move conform to this principle? To clarify this issue, it is necessary to revisit the previous situation.

When this game of chess reached the 49th hand, because Li Xiangping had been struggling to get to the ground before, he had snatched 3 and a half of the 4 corners, and in the previous process, the opponent Zhang Xu seemed to be very "cooperative", so at that time, this game of chess had formed a more typical, even slightly extreme "implementation of confrontation" pattern.

Zhang Xu's 50th move is a key to the game, as soon as this move is played, a huge appearance of white chess has a faint skeleton-----

The reason why it is just a "skeleton" is because it is still early after all, and the whole chessboard is still very open, and the appearance is not only not completely realistic, but also not even "formed", so it can only be called "a skeleton with a large appearance".

However, despite this, when Zhang Xu's 50th move came out, the big appearance of white chess actually became the focus of the overall situation at the first time, and Li Xiangping knew very well in his heart that the attack and defense around this appearance had become the key to the victory or defeat of this game.

It is not an exaggeration to say that it is the only key.

Li Xiangping's long exam just now, of course, was also making a fuss about this big picture, and he was thinking about how to do it.

However, it is a pity that it may be because Zhang Xu's choice just now is really good, of course, it is more likely, it is because Li Xiangping's current strength is not enough, in short, he thought of several plans just now, but none of them can satisfy Li Xiangping.

Around the large-scale attack and defense, of course, there are only two most common methods, one is the so-called "shallow elimination", and the other is of course "penetration", deep penetration.

When Li Xiangping was taking the long exam just now, he used these two conventional ideas to consider 5 selection points, of which 2 selection points were "shallow elimination" ideas, and the other 3 were "entering" methods.

Of course, 5 points represent 5 roads, and each road can derive a lot of changes, but unfortunately, in Li Xiangping's own calculations, he didn't find any change maps that could satisfy him.

It is precisely because of this that Li Xiangping thought of the step of "entering the boundary slowly" just now.

Because in his opinion, the reason why he didn't find the ideal map just now is not necessarily that those 5 points are not good, it is likely that the time to place those points is not good-----

This kind of problem is of course very common in Go, if you choose the same point and play at different times, the effect may be very different, you are a bad hand at this time, and you may become a good hand at another time.

Considering that he had thought about 5 points, it was impossible for the opponent to take all the points in his next move, so in this way, he decided to "wait" for a hand for the time being, and then decide his own way of playing after seeing the opponent's next move.

And the above one, that is actually the chess theory of "entering the realm should be slow", this is the development of Go for so long, the valuable experience summed up by human beings, at least so far, Li Xiangping is still convinced of this, so he made this choice just now.

So is this the right choice? Of course, Li Xiangping himself doesn't know-----

At least he didn't know it when he played it, otherwise he wouldn't have made a move.

Not only did he not know when he fell, but even when he saw Zhang Xu's next move, that is, when he saw the 52nd move of the whole world, he even thought that his hand just now might be good------

Because Zhang Xu's chess move was expected by Li Xiangping.

This move is also one of the five points that Li Xiangping considered before.

Well, if Li Xiangping did this just now, then it can be called "shallow elimination", and now what about Zhang Xuxia? Of course, this chess move is "wei", the "wei" of Chiguoguo.

White 50 hands plus 52 hands, as soon as these two hands appear on the chessboard, the appearance of white chess is not only the "skeleton", the appearance has been fully formed, if you let white add a hand, then the whole appearance of white chess will immediately become real, and he will surpass the global field of black chess with a big empty space.

Then at this time, of course, Li Xiangping could not let white strengthen his hand. In fact, when he first saw the 52nd hand of the overall situation, Li Xiangping was still happy in his heart, he thought that everything was under his control.

Li Xiangping's next move didn't take much time, and he quickly fell to the 53rd move in the world------

This move is also one of the five points that Li Xiangping thought about before, and this move was called "entering" when it was played at that time, and it was played at this time...... Of course, it's still called "breaking in".

It's just that Li Xiangping thinks that of course, they are also "entering", but there is an essential difference between the two.

If you play this chess hand in front of you, then this chess hand may be a little unreasonable, because Li Xiangping has calculated a tough cutting method for white chess, and although he will not die in the subsequent battle, he will be attacked by the opponent very badly, which belongs to the typical "not to die but also to peel the skin".

However, now it is different, because I just "waited" for a step, and this move just now can actually play a role in responding.

In other words, in fact, 51 and 53 moves can be regarded as a "combination punch", this set of "combination punches", Li Xiangping believes that he is fully combatable, while also opening a gap in the appearance of white chess, black chess does not have to worry about being attacked too badly.

As soon as Li Xiangping's 53rd move came out, it seemed that the opponent had also stopped, Zhang Xu's 52nd move just now was very fast, but when he saw the 53rd move, his hand had stopped and began to think about the chessboard.

And when the opponent was thinking, Li Xiangping of course did not stop, he checked the follow-up changes again.

After checking that the calculation was correct, that is, after thinking that his "combination boxing" was indeed feasible, seeing that the opponent still hadn't fallen yet, Li Xiangping couldn't help but feel a little proud.

He felt that after two months of online training, his strength should have been significantly improved, otherwise, he would not have been able to play such a subtle and reasonable good chess today.

“.... Well, this may be the so-called realm, after two months of training, it seems that my realm has really improved a lot, this is "entering the realm should be slow", in the past, then I can't play such a realm combination ......"

Just when Li Xiangping was complacent, the time came to about 2 o'clock in the afternoon, and at 2 o'clock, Zhang Xu finally finished the long exam, and he fell behind the 54th hand in the overall situation.

Li Xiangping was stunned.

That was his first reaction.

Of course, his reaction was normal, because the move was completely unexpected by him, and it was not at all within the range of his previous calculations.

Li Xiangping's good mood gradually disappeared, and he even became a little headache.

The above was his second reaction.

Of course, his reaction was also normal, because when he finished interpreting this move, he found that this move seemed to be a good move, and this move was quite difficult to deal with.

Li Xiangping felt a little ashamed, ashamed of the word "realm" that he had just thought of.

The above is Li Xiangping's third reaction.

His reaction was actually very understandable, because he suddenly found that compared with his previous realm of "entering the realm slowly", Zhang Xu's realm seemed to be higher.

This is a more subtle step, a more far-reaching calculation, and a good move to win the realm of "last, middle and first" in Go!

"Damn, is my current realm even inferior to Zhang Xu......

Thinking of this, Li Xiangping couldn't care about being ashamed, and he couldn't care about blushing, he cheered up and thought hard about how to break the enemy again.
