How to calculate the victory and loss of Go How to calculate the victory and loss of Go?

In Go, the winner is determined by the number of intersection points enclosed, and the intersection point is the 19 19 361 points obtained by the intersection of 19 horizontal lines and 19 vertical lines in the chessboard.

or the number of children, whichever side wins. But generally speaking, Black has to post a goal to White first to balance the advantage of the first move, that is, to add a goal to Black's at the end. Note that the meaning of "goal" and "sub" at this time is different from the previous one, and the "purpose" and "sub" here refer to two different methods of calculating victory and defeat, and either one can be used, and the meaning is the same.

Let's start with the calculation method of "eye": the difference between the number of meshes of the two sides, such as black and white, the result is that white wins.

out of the eye, because Black wants the post first.

Let's talk about the calculation of "pieces": half of the intersection is (half of the purpose), if one side exceeds this number, the winning number of children is the difference between the number of pieces of that square, as in the example above, i.e. White wins 3 3 4 pieces.

Due to historical reasons, the rules of Go are not uniform in the world. At present, there are 10 teams and individuals in the world, but basically the rules to be used are decided according to the requirements of the sponsors, and the same is true for other regional Go competitions around the world, which can sometimes be confusing. At present, there are three types of Go rules used in the world: Chinese rules, Japanese and Korean rules, and Ying's Cup rules, which are actually two major rule systems.

The core problem of Go rules is how to calculate the winner and loser, and there can be two completely different methods for calculating the victory and defeat in Go, namely the "number method" and the "number method", thus forming two rule systems, namely the Chinese rules that use the "number method" and the Ying rule (the Ying rule is called the "counting method", the name is different, but the essence is the same) and the Japanese and Korean rules that use the "number method". The rule system of the "number sub method" follows the principle of "sub-emptiness is ground", that is, whether it is sub-emptiness or real emptiness, it is the "land" of one side; The rule system of the "number method" is not to count the children, but only the number. The differences of opinion on the unification of the rules are mainly on which one is more reasonable, the number or the number.

Originally, it is okay to use these two different methods of calculating the victory and defeat in the game of Go, but in fact, under normal circumstances, this does not affect the outcome of the victory and defeat (so many people think that the difference between the two rule systems is very small), but it is different in some special cases (such as whether to make up the game in the real air and whether to make up the chess in the real space). Chinese rules emphasize that actual combat is the only criterion for testing the reasonableness of all moves, and if it is a live chess, it must not be killed; If it is a dead move, it will definitely be killed, such as "four corners of the game", and finally whether it is dead or alive can only be determined according to the actual combat situation, and there is no need for hard and fast rules. However, in the rules of Japan and South Korea, it is artificially hard to stipulate that this chess shape is a dead chess, and this obviously unreasonable provision is caused by the rule system of "number law".

This is a dilemma: if the "number method" is adopted, it cannot be used to solve the dispute; If we want to resolve disputes through actual combat, we must abandon the "number method" and adopt the "number method".

Lesson 22 of Go – Winning or Losing Go.

There are at least three ways to calculate the winner or loser in Go:

1. Number method: The method of calculating the victory and defeat of Go commonly used in China, also known as the Chinese number method, the current Chinese Go rules stipulate: 3 and 3/4 of the black chess stickers, that is to say, 185 pieces win, and 177 pieces of white chess wins; Of course, China also has a number.

2. Number method: Japan and South Korea both use the number method, and South Korea is learning from Japan, referred to as Japan-South Korea rules, but it is not the same as China's number rules, such as double-live and eyeless.

3. Ying's rules: one of the three major Go rules alongside Chinese rules, Japanese and Korean rules, founded by Mr. Ying Changqi. There are also flaws, such as the fact that a false hand can be used as a robbery, which is different from the Chinese rules.

But it also has his advantages: the use of the fill-in counting method, that is, after the final game, fill in the blanks formed by both sides of the grid, and then compare who has more left, more left, indicating that the total empty is less, and it loses.

Go, a strategic two-player chess game, was called "Yi" in ancient China and "go" in the West. It is popular in East Asian countries (China, Japan, South Korea, and North Korea), and is one of the four arts of qin, chess, calligraphy and painting. Go originated in China, is said to have been written by Emperor Yao, and has been recorded in the Spring and Autumn Period and the Warring States Period.

During the Sui and Tang dynasties, it was introduced to Japan through Korea and spread to Europe and the United States. Go contains the rich connotation of Chinese culture, and it is the embodiment of Chinese culture and civilization.

Go uses a square checkered chessboard and black and white round chess pieces to play the game, and the chessboard is divided into 361 intersection points with 19 vertical and horizontal line segments, and the chess pieces walk on the intersection points, and the two sides alternately move the chess, and cannot move after the pieces fall, and the one with more enclosures wins. Because Black took advantage of the first move, it was artificially stipulated that Black should give White a post at the end of the game.

In ancient China, black and white placed two discs at the diagonal star position (diagonal star layout), which was a seat system, with white taking the lead. The modern game of Go was developed from Japan, and the rule of the seat was abolished, and black came before white, making the changes of Go more complex and changeable. Go is also considered the most complex board game in the world.

Chinese rules.

1. The rules for sticking 3 and 3 4 subs:

The first step is to remove the dead son.

The second step is to count only the number of points around one side and record them (generally the points are in units of ten points).

In the third step, if the number is black, subtract 3 and 3 4 discs, and if the count is white, add 3 and 3 4 discs.

In the fourth step, the result is compared with 180 and 1 2 (half of the 361 points on the board), and if it is exceeded, it will be considered a victory, otherwise it will be a loss. The number of black eyes is more than the number of subs, while the number of white meshes only needs to exceed the subs to win. In layman's terms, 177 pieces of white pieces win, and black pieces win.

2. Let the first and let the son: let the first do not stick the eye, let the child paste back half of the number of let children (as if the transferee received the order in advance).

Japan-Korea rules. The rules are the same in Japan and South Korea, using the number method, and the black finale is 6 and a half meshes. Count the number of eyes of one side and record it, then count the number of eyes of the other side and record it, then black subtracts 6 and a half meshes, and finally compares with white, and the more wins.

It is worth mentioning the saying "one son, two eyes". Although the method of calculating the winner of Go is different, it is manifested in a specific game, sticking m = sticking 2m, and winning n = winning 2n. Here's why:

The number method is to calculate the deviation between either side of black and white and the attribution number (361 2=; The flounder method is the difference between the number of meshes obtained by the black and white sides.

Lesson 22 of Go – Winning or Losing Go.

After both sides confirm the endgame, the number or number (according to the rules). Black needs to repay a certain amount of interest, with the following differences in numbers or numbers:

The rules of Japan and South Korea are based on numbers. Since 2003, the number of black squares has been increased to 6 and a half meshes, and there is no need to go until the end of the single officer. The more the eye wins.

The current rule in China is that the black paste is 3 and 3 4 subs (equivalent to 7 and a half meshes), and the number of subs must be carried out after the end of the single official. The one with more children wins.

Let's explain the "winning half" problem you talked about. In fact, there will be no winning half-son, only winning 1 4-son or half-eye, and the result of these two is the same. Why does 1 4 sub equal to a half-eye?

It seems that you are a beginner, so I will explain to you the concept of mesh. The purpose is the area that is enclosed on the chessboard and has been occupied by you without a child. Strictly speaking, the zi is the goal, which is equivalent.

However, in daily games, it is easy to give people the concept of "one son and two eyes", because the method of calculating victory and defeat is different. The number method calculates the victory and defeat, which is the deviation between the calculation and the standard; In the number method, the difference between the two sides is calculated. The simplest analogy:

Three apples, let's divide them. You take two, I take one. In this case, in the method of counting, it is considered that you (more than the standard of 1 and a half per person) take half more, that is, win half a child; In the method of numbers, if you think that you (than me) take 1 more, you will win one eye.

Therefore, it gives people the misunderstanding of "one son and two eyes", but in fact, children and goals are concepts of equal value.

In addition to the endgame, there is also a more common way to end the game, where one side judges that the gap is too large and it is impossible to catch up again, and admits defeat in the middle game.

In addition, the final game that still exists at the time of the game may be:

1.The game is lost after overtime.

2.Violation of rules or discipline may result in a warning or penalty. When a warning is given, the warning party will be penalized on the basis of the original regulations when calculating the outcome of the game. If a player is given two warnings in a game, the game is lost.

3.In principle, it is forbidden to prohibit the rare exceptions of the recurrence of the global homomorphic cycle, such as the cycle of three tribulations, the cycle of four tribulations, immortality, and the double mention of two sons. According to different competitions, corresponding supplementary regulations can also be formulated, such as no wins, draws, play-offs, etc.

In the middle of some chess games, the players on the disadvantaged side think that their gap is too big, and when they continue to return to the sky and have no hope of conceiving the defeat, then the winning side wins in the middle game.

When the final count is reached, the following rules are followed.

Chinese Go Rules **Encyclopedia.

Article 7 Finality.

1. The game is final when both parties unanimously confirm the completion of the move.

2. When one of the players admits defeat in the middle of the game, it is the final game.

3. The continuous use of virtual by both sides is the final game.

Article 8 Live and Dead.

1. At the end of the game, all the pieces that cannot be extracted are live chess, as confirmed by both parties.

2. At the end of the game, the pieces that can be extracted are dead pieces after confirmation by both parties.

Article 9 Calculation of Winning and Losing.

In the game where the moves are completed, the number method is used to calculate the winner and loser. After the dead pieces of both sides are cleared out of the board, the live pieces of either side and the points surrounded by the live pieces are counted in pieces.

Half of the empty spots between the two live pieces.

Half of the total number of points on the board is the number of points. If the total number of points scored by one team exceeds this number, it wins, which is equal to the number of points that are a draw, and if it is less than this number, it is negative.

In the case of a Go competition that adopts the post method, the winning and losing criteria will be set separately.

If you continue according to the rules, the side with fewer goals will fill the land you occupy first, resulting in the exhaustion of your chess spirit. Fillers are meaningless except to delay time, because they can't increase the number of meshes they occupy.

Judgment of victory and defeat: Generally speaking, 177 pieces of white chess are the winner, and black pieces are the winner. China uses the numerical rule, and because Black has a certain advantage first, all rules use the sticker system.

The rule of sticking 3 and 3 4 discs: if the number is black, subtract 3 and 3 4 discs, and if the count is white, add 3 and 3 4 discs.

The result is compared with 180 and 1 2 (half of the 361 points on the board), and if you exceed it, you will win, otherwise you will lose. The number of black eyes is more than the number of subs, while the number of white meshes only needs to exceed the subs to win.

According to Chinese rules, the Go board is 19x19=361 intersections, and theoretically one side occupies more than half of them, that is, 181 intersections, which is a victory. However, since black has a certain advantage in moving first, in order to balance this advantage, the rules of Go stipulate that black must occupy at least 185 intersections to win, while white only needs to occupy 177 intersections to win.
