The "break" that Lao Shi refers to is actually the break point left on the outside of the black chess pattern when there are more than 60 moves in the game.

Well, although Lao Shi didn't say it explicitly, and there were many breakpoints on the chessboard, based on the tacit understanding between the two of them, Li Xiangping knew the breakpoint his plug-in was talking about as soon as he heard it.

Not only that, after receiving the plug-in prompt, Li Xiangping knew within a second that it was a good move!

It was a very clever "test move" and a very advanced tactic. With this move, White would immediately be in a favorable position in the upcoming battle.

So the move Lao Shi pointed out is likely to be the winning move in this game!

I believe that most Go enthusiasts have heard of the name "Trial Hands" in Go, and they should have heard many professional players say: "Trial Hands is a relatively advanced method in Go", but in the end, advanced

Many chess fans may not know where it is.

Perhaps from today's practical example, everyone can understand a little bit about the magic of "trying it out".

In fact, as early as the 60th move, before Li Xiangping made the "move of will", he had already targeted the breaking point of the black chess, because at that time, that breaking point was the weakest point of the overall appearance of the black chess.

It's a pity that although it was considered a weakness, it could not be regarded as Black's "flaw" at the time -------

If Li Xiangping had rashly cut off the move at that time, based on the overall configuration at that time, there would be no benefit at all from white's head-on battle.

It is precisely because of this that Li Xiangping did not dare to make a decision at that time, but adopted other tactics.

After that, neither side started fighting in the midfield area, but started fighting for officials in the corners of the chessboard.

So now, the situation in the midfield area has basically not changed. The breakpoint still exists, and it is still considered the weakness of black. However, if white moves directly, it seems that it still cannot be established.

But there is a catastrophe about to appear on the chessboard.

A valuable robbery with a total number of close to 15 items.

It is precisely because of the existence of such a tribulation that the breaking point that was not a "flaw" in the past has now become the dog's flaw!

Why do you say this? Let’s use this basic principle in Go to explain this problem:

The most important thing to judge the quality of a chess move is to look at the opponent's response. If your next chess move can put your opponent in a dilemma, make your opponent's response poor, and you will never be able to find a change that satisfies you.

So this kind of chess can be clearly said to be a good move.

And today’s “break”.

And you can only make this "break" at this time, it is such a good move!

Now put yourself in another’s shoes and think about this issue from a dog’s perspective.

Facing White's "break" move, if you only look at that part, the dog will certainly not be afraid, because the surrounding situation has basically not changed, and the dog will not be afraid at all in frontal combat.

But now there is a catastrophe on the chessboard.

Although this calamity dispute did not appear, it was completely foreseeable: for a long time to come, that calamity contention would be the main contradiction on the chessboard.

Since it is the main contradiction, then whenever you play chess anywhere on the chessboard, you must always be staring at such a main contradiction.

And what is the key factor that determines the success or failure of a robbery? Of course it is the robbery materials!

Yes, Li Xiangping's "break" step, although it can't gain any results in that part, it can affect the amount of robbery materials, and then use this method to connect with the main contradiction of the overall situation, and then directly affect the overall situation.

Victory or defeat.

The above is the wonderful taste of "trying it out"!

Because of the existence of "trying hands", it fully explains that Go is an overall and holistic game.

A method that seems to be untenable locally will have an important impact on the overall situation, and can even directly determine the outcome of a game of chess.

In addition, there is a game of chess introduced earlier in which the second-generation dog defeated the third-generation dog. A tetsuji that seemed unsolvable and extremely sharp in a local area may become a defeat in the overall situation.

Among all human chess games, it seems that only Go can harmoniously unify such contradictions. Therefore, Go is worthy of being the most complex chess game invented by mankind.

"55,56,57..."

Li Xiangping still followed his own rhythm. When the countdown reached 57, he "cut off" his hand and slapped it on the chessboard. Then while waiting for his opponent to make a move, he continued to think about it from the perspective of a dog.

Think about how the dog would respond to this move.

Faced with this "broken" hand, dogs actually don't have many ways to deal with it, and there are only two that they see.

Of course, here we must first rule out the possibility of the dog losing the lead. Don't look at the fact that this hand break is not valid locally, but it cannot allow White to play two consecutive moves in the middle------

If the dog dares to escape first, then Li Xiangping will not start a robbery with the dog.

Anyway, with the "group" move just now, White's chess piece is partially alive, so it doesn't matter even if all the empty corners are destroyed by the opponent, the value is definitely not as good as two consecutive moves in the middle.

Since the possibility of detachment has been ruled out, dogs are left with two local responses.

One way is to just ignore it, pretend that the catastrophe does not exist, and do whatever you want in that part of the world.

However, if the dog really dares to play like this, White will have at least 5 more calamity materials, and after White has so many more calamity materials, it will definitely not be able to win the next calamity battle.

Another way to win is to take into account the calamity contention on the other side of the chessboard, and then choose to compromise locally and completely eliminate White's calamity material in the center area at the cost of losing 2 pieces.

Well, compared to a calamity worth 15 goals, a two-movement game is certainly a trivial matter. If the dog can win that calamity, the loss of the two-movement game is worth it.

It's just a pity, well, it's a pity from the dog's point of view. Once the dog chooses to compromise and loses 2 pieces locally, this will actually also affect the overall calamity.

The principle here is this: the total value of the robbery is 15 items, so during the robbery, the robbery materials found by either party must match this value.

If you find a move worth 14, it can barely be considered a robbery, but if you find a move worth only 10...

The opponent will definitely be happy to eliminate the calamity, and then make a net profit of 5 items through a calamity fight.

It is precisely because of the problem of "matching of robbery materials" that if the dog loses 2 eyes here, Li Xiangping will find it easier to find the robbery materials, and it will be more and more difficult for the dog to find the robbery materials.

Li Xiangping only needs to find a robbery material worth 13 goals.

And if the dog wants to win or lose, it will be a little behind before considering it. Every robbery material it finds must be worth more than 19 items.

Obviously, the chessboard is only that big, and there will definitely be fewer valuable robbery materials. Therefore, calculated in this way, once the dog chooses to make a compromise by losing 2 moves in advance, the local robbery materials will be eliminated, but from a global perspective, it will still

will face the dilemma of insufficient resources.

Such an example actually once again demonstrated the integrity of Go, which is an overall game. It took Li Xiangping about 5 minutes to sort out all the clues on the board. The more he thought about it, the more embarrassed he became for the dog.

, the more I think about it, the more I feel that the dog is not up to it.

Since the dog didn't respond, Li Xiangping felt that victory was already waving to him.

"...Hey! It's been another 5 minutes, why hasn't the dog made a move yet? Hehe, today I played chess, and then Lao Shi played chess, forcing the second-generation dog to take the test for more than 5 minutes. It's a pity that Jueyi and other domestically produced

The dog hasn’t come out yet, so it doesn’t have the conditions for walking the dog yet. Otherwise, I really want to take the current situation and walk the dog to see what the winning rate is now..."

Well, of course Li Xiangping still doesn’t know that he can’t walk his dog, but he can in Europe.

And after the dog's last long test, Fan Erduan and Yan Qing had already experienced it. Now that they saw the dog taking the "long test" for more than 5 minutes again, they immediately urged Dr. Huang to turn on the background monitoring again.

The winning rate displayed in the background left the entire Afagou team speechless.

Eighteen point three percent!

After Li Xiangping "broken" his hand, the background showed that the dog's winning rate dropped by nearly 20 points, and now it is less than 20%!

Seeing this situation, Yan Qing suddenly asked:

"Hey, Dr. Huang, since the winning rate is now below 20, shouldn't the dog start making some meaningless hits like it did to Lee Sedol last time?"

The first generation of dogs, when the Google team set up the competition program, they still thought that it was relatively simple. Dogs were based on the winning rate, and once the winning rate dropped to a certain critical point, some inexplicable "beaters" would appear in the dogs.

Because at that time, only "beating the general" can maintain the previous winning rate. Playing any other chess will cause the winning rate to continue to decline. It is precisely because of this principle that humans can see dogs continuously "beating the general".

Faced with Yan Qing's inquiry, Dr. Huang, who has a 6D online level (note that Dr. Huang is a 6D, not an amateur 6-dan level as some netizens said) shook his head and replied:

"No, we have now improved the program and adjusted the critical point to 5%. This means that as long as there is still a 5% winning rate, the machine will still operate normally."

"Oh, that's good. Let's continue watching Li Xiangping's performance and see if he can withstand the impact of the master in the end."

Just like the previous time, the dog once again took a "long test" for about 10 minutes before making a move. With Li Xiangping, the dog chose to stick to the local area and deal with itself in this way.

Li Xiangping cheered up and once again concentrated on the game. Today, he was eager to hold the victory firmly in his hands.

Time passed bit by bit, and then Li Xiangping had entered a state of selflessness. He felt that his mind was extremely clear, and even in his eyes, the crisscrossing black and white chess pieces on the chessboard had formed an extremely beautiful picture.

The time has come to 10:15 p.m. At this time, Li Xiangping does not know that in the future, countless chess fans are already extremely excited, and everyone is waiting for the moment when the dog surrenders.

It’s the moment when machines surrender to humans! Call the shots

At 10:20 in the evening, at this time, the game had reached more than 240 moves. At this time, Dr. Huang, who had been monitoring the background, saw that the dog's winning rate had dropped to less than 5%.

"Haha, you can admit defeat." After saying this, Dr. Huang made the decision for the dog and pressed the admit defeat button on the computer screen.

Seeing the dog admitting defeat, Li Xiangping laughed at that time.
Chapter completed!
