weiqi

Weiqi is an intellectual game, which originated in China and has a history of more than 3,000 years. Weiqi contains the meanings in ancient philosophy, such as one yuan gives birth to two instruments, two instruments gives birth to four elephants, four elephants give birth to eight diagrams, a place with a round sky, solar terms in the 19th agricultural season, days of 360 weeks and so on.

Not long ago, the Chinese Weiqi Association (hereinafter referred to as the Association) revised the Grade System of Weiqi Amateurs in China and the Grade System of Weiqi Amateurs in China, which aroused widespread concern of Weiqi enthusiasts all over the country and Weiqi workers in various provinces and cities. In order to let you know more about the contents of this document and the revised outline, we will make the following analysis according to the revision process of this document.

At the beginning of 2005, the State Sports General Administration (hereinafter referred to as the General Administration) held a meeting on athletes' technical level, and some general administration centers and provincial and municipal sports bureaus sent representatives to attend the meeting. The content of the meeting is to solicit opinions on the revision of athletes' technical grades, to convey the ideas of the General Administration on the management of athletes' technical grades, and to introduce some latest preferential policies of the General Administration and the Ministry of Education on athletes' going to college. (See the relevant documents of the Ministry of Education and the General Administration for details. ) emphasizes the importance of strict management of athletes' technical grades, and requires athletes of relevant grades to make public announcements before obtaining the title of grades in the future, so as to be fair, open and just. Amateur position is an important reference standard for the technical level of Go players (1 players and below). According to the spirit of the General Administration, the association also needs to strictly manage amateur posts to be fair, open and just.

As early as 1992, the association established the amateur level of Go in China. At that time, I borrowed some experiences from other countries, the main purpose of which was to increase the interest of Go lovers. In addition, the policy of athletes going to college at that time was not obvious in Go, so people did not strictly associate amateur position with grade certification. Now amateur jobs must be managed according to grade certification. It can be said that this is the biggest difference between China's Go Amateur Grade System and China's Go Amateur Grade System and 1992 China's Go Amateur Grade System.

The following highlights several changes:

First, publicity

1. Players who have obtained the amateur certificates in paragraphs 7, 6 (for 1 level athletes), 5, and 4 (for level 2 athletes) issued by the Chinese Go Association must be publicized on the Go website of the Chinese Chess Academy.

Note: Athletes above Grade 2 can already enjoy greater preferential policies, so they must be strictly required.

2. The chess institutes, chess associations or Go associations under the jurisdiction of the sports bureaus of all provinces and municipalities directly under the Central Government (hereinafter referred to as the first-level institutions) shall record the information of players who have obtained amateur certificates of 1 or above within their respective jurisdictions and report them to the associations for later use.

Note: I hope that local chess associations will strengthen information management and better organize activities for Go lovers. The association has mastered the information of Weiqi fans all over the country, which is convenient for statistics, provides information and builds an interactive platform for fans.

Second, identify

1. First, the first-level institutions recommend expert chess players to the association, which will take effect after the approval of the association.

Note: Enhance the authority of local chess associations.

2. The amateur recommended by the appraisers should be over 18 years old, and the amateur position obtained through appraisal cannot be used as the basis for applying for the level athletes.

Note:/kloc-Amateur chess players under 0/8 years old are the most sensitive and contradictory group of athletes. We encourage small chess players to get good results in the competition and get amateur positions in line with their own strength through their own efforts.

Third, the annual review

In order to make local chess associations better meet the requirements of the General Administration and the Association, since 2005, the Association has implemented the annual examination system of the first-level institutions.

Note: Units that practise fraud, issue certificates indiscriminately or fail to put on record shall be supervised. Corresponding measures will also be taken for the first-level institutions that have been inactive for a long time.

Fourth, the certificate

1, unified reservation. The first-level agency reserves the required certificate amount from June 65438+February 1 to June 3 1 every year, and receives the reserved certificate after passing the annual examination.

Note: unified booking is convenient for management and reduces workload.

2. Certificate number. The serial number of the festival card is ***9 digits, and the numbering method is as follows: the first 3 digits are the first 3 digits of the ID card number of each province (city), the middle 2 digits are the year number, and the last 4 digits are the serial numbers of each grade issued in the current year. The top three figures of China Weiqi Association are 000.

Note: It is convenient for statistics.

V. Military rank system

Adopt the suggestion of local chess association, increase the grade system, and facilitate popularization.

This is the first revision of the amateur level of Go in China since 1992 was formulated by the association. Since 13, Go has become more popular all over the country, loved by more people, and its social influence has increased. The amateur position of Go is well known by the society as a standard to measure the level of chess players, and the position certificate is also accepted by the society as grade certification. This is the result of the development of Weiqi, the heartfelt support of our vast number of Weiqi fans, and the hard-won result. The more amateur positions can reflect the actual level of the players, the higher the social awareness will be, and the more rewards the players who really work hard at Go will get. On the contrary, if we neglect to maintain this system and standard, social recognition will gradually drift away.

In short, on the one hand, the association's management of amateur positions should conform to the regulations of the General Administration on the technical level of athletes, on the other hand, it should absorb the suggestions of the vast number of Go lovers and local Go associations and gradually improve them.

chinese weiqi association

September 20(th), 2005

Transfer from Sohu

Go is called "hand talk". Both sides communicate with each other in the language of moving the ball, and each hand transmits information.

Tactically, there is a saying in Weiqi that "Jinjiao has a silver border and a grass belly". It means that the same amount of land is enclosed, and both sides of the chessboard can be used on the corners of the chessboard, which requires the least force (number of hands); The edge of the chessboard can only use one side of the chessboard, which requires more strength (number of hands); In the chessboard, there is no edge in the middle abdomen, which requires the most force (number of hands). Therefore, the mainstream game mode is mainly based on the corners of the chessboard.

Weiqi is an economics. Different from other chess events, the process of catching some opponents' pieces first and then pursuing the goal to win, Weiqi takes the side that controls the territory as the winner and pursues the numerical advantage; Go, like other chess events, is also played by both sides in turn, and the opportunity of playing chess pieces and moves is a scarce resource for players. Economics is a science that studies how to allocate scarce resources for different purposes in order to satisfy the infinite desires of human beings as much as possible. Weiqi studies how to allocate the limited military resources well and satisfy the desire of the players to control as much territory as possible. It is easy to use your own six pieces to fence the corner with two live chess, but the efficiency of resource allocation is very low, and your opponent's six pieces can completely surround more live chess and gain an advantage.

The core concept of economics (1) is opportunity cost. You can't have your cake and eat it. Both fish and bear's paw are opportunity costs and must be chosen. This is also reflected in the unique "robbery" of Go. Rob and don't rob is the opportunity cost of each other, and we must choose. The principle of comparative advantage is also applicable.

In fact, choice runs through the whole process of playing chess. If you understand Go from the perspective of moderation or' harmony', you will have more experience of life.

Different from chess, military chess and military chess, the number of sub-forces on the chessboard is monotonously decreasing with the progress of the chess game, and it is impossible to increase. In addition to being eaten, the number of children on the board of Go generally increases with the progress of the game. Therefore, except the first move, every move is an increment on the basis of the original situation, and every move behind it should be marginal analysis, which is an important research method of economics.

Game theory is summarized from all kinds of games including Go, and it is also applicable to Go.

Another important principle of economics is that more expected returns are often accompanied by greater risks, and so is Go. It is more reliable to surround two destinations in the corner with your own six pieces. You can be the master in these two destinations without risk, but the income of only two destinations is very low; It is more profitable to enclose more sites with the same six blocks, but sometimes such sites may not be able to make their own decisions, and there is a risk of being broken by opponents. How similar this is to the economic phenomenon!

Go is a bit like enclosure in economic history.

The origin of weiqi

Weiqi is figuratively likened to a black-and-white world. It is a favorite entertainment and competitive activity in ancient China, and it is also the oldest board game in human history. Because it integrates science, art and competition, it has the characteristics of developing intelligence, cultivating will quality and flexible strategic and tactical thinking. Therefore, it has flourished for thousands of years and gradually developed into an international cultural competition.

Weiqi, called chess in ancient China, can be said to be the originator of the whole ancient chess. It is said that it has a history of more than 4,000 years. According to Shiben, Go was written by Yao. Zhang Hua, a Jin native, also said in the Natural History: "Shun pretended to teach his son to be a fool." Yao Shun is a legendary figure. The theory of making Weiqi is not credible, but it reflects the early origin of Weiqi. During the Spring and Autumn Period and the Warring States Period, Weiqi has been widely circulated in the society. Zuo Zhuan's Twenty-five Years of "xianggong" once recorded such a thing. In 559 BC, the monarch of Wei was deported by Dr. Ning Zhi and others. Later, Ning Zhi's son promised to welcome Wei Xiangong back. Criticized: "Ningjia is going to be in trouble. The players are indecisive and unable to couple. What is the situation? " The word "indecision" in Weiqi is used to describe political indecision, which shows that Weiqi activities have become a common thing in the society at that time.

Qin destroyed the six countries and unified the whole country. There are few records about Go. It is recorded in the third volume of Miscellanies of Xijing that Du Fu in Ling Du was the first person in the world in the early years of the Western Han Dynasty, but such records are as few as stars, indicating that the development of Weiqi was still relatively slow at that time. By the early years of the Eastern Han Dynasty, the society was still in a state of "being knowledgeable in the world and being good at chess". It was not until the middle and late Eastern Han Dynasty that Weiqi became popular again. 1952, archaeologists found a stone chess board in the Eastern Han Tomb No.1 in Wang Du, Hebei Province. The chessboard is square with four legs under it, and the situation is 17, which provides vivid materials for the shape of Weiqi chessboard in Han and Wei Dynasties. Associated with the frequent wars in Han and Wei dynasties for hundreds of years, the battle of Go has also become an important tool for training military talents. Ma Rong in the Eastern Han Dynasty regarded Go as a small battlefield and played it as a battle. "Three feet game is a battlefield;" Chen Jushi died, and the two enemies are even. "At that time, many famous military strategists, such as Cao Cao, Sun Ce and Lu Xun, etc. During the Three Kingdoms period, he was outstanding on the battlefield and in chess. Wang Shen, one of the famous "seven sons of Jian 'an", is not only famous for his poems and prose, but also a master of Weiqi. It is said that he has an amazing memory, and he knows the play and style of Go like the back of his hand, and he can re-display the "bad" chess he has seen.

The Go system in China has undergone two important changes in history, mainly due to the increase of local roads. Before and after Wei and Jin Dynasties, important changes took place for the first time. Han Weidanchun's Book of Changes said that before and after the Wei and Jin Dynasties, "there were 17 kinds of vertical and horizontal chess, a total of 289 kinds, 150 pieces of white chess and 150 pieces of black chess". This is exactly the same as the Go system of the Eastern Han Dynasty found in Wang Du, Hebei. However, the Chess Classic of the Southern and Northern Dynasties, discovered in the stone room of Mogao Grottoes in Dunhuang, Gansu Province, records that the chess game at that time was "361, imitating Sunday." Explain that Go with 19 channel has become popular at this time. This is exactly the same as the current chess game, reflecting that Go at that time had its original customization.

Due to the rise of metaphysics in the Northern and Southern Dynasties, scholars are proud of speaking clearly, so playing Go is more prosperous, and playing Go is called "hand talk". The upper rulers are all good at playing chess. They set officials by chess, established a "chess product" system, and awarded "character" (grade) to "chess players" with a certain level. Chess at that time was divided into nine categories. "Biography of Heather Liu Yun" contains: "Liang Wudi is good at playing chess, and there are 278 people on the chess score." This shows the universality of chess activities. Now Japanese Go is divided into "nine segments", which is the reason. These changes have greatly promoted the improvement of Weiqi entertainment technology and laid the foundation for the further development of Weiqi entertainment in China and its spread abroad.

The Tang and Song Dynasties can be regarded as the second great change period of Weiqi entertainment in history. Due to the emperor's love and other reasons, Weiqi has developed by leaps and bounds, and the wind of playing chess has spread all over the country. At this time, Weiqi lies not only in its military value, but also in cultivating sentiment, pleasing body and mind, and increasing wisdom. Playing chess, playing the piano, writing poems and painting are regarded as elegant things by people and become entertainment items suitable for men, women and children. The silk painting "Ladies Playing Chess" unearthed from the Tang Tomb at Astana 187 in Turpan, Xinjiang, depicts the image of aristocratic women playing Go at that time. At that time, the chess game was dominated by 19, and the players had changed from square to round. 1959 The porcelain Weiqi board unearthed from Zhang Sheng's tomb of Sui Dynasty in Anyang, Henan Province, and the ivory chess board with wooden clips presented to Emperor Xiaowu of Japan in the Tang Dynasty and now stored in Zhengcang Hospital of Japan are 19 in both vertical and horizontal directions. The black and white round chess pieces in Tang Dynasty collected by China Sports Museum and 50 black and white round chess pieces unearthed from the tomb of Yang Gong Song in Huai 'an all reflect the changes and development of Weiqi in this period.

The implementation of the system of "playing chess with imperial edict" in the Tang Dynasty is a new symbol in the development history of China Weiqi. The so-called equal-faith chess is a professional chess player who accompanied the emperor in the Hanlin Academy in the Tang Dynasty. At that time, the chess players dedicated to the palace were all selected through strict examination. They all have first-class chess skills, so they are called "national players". Famous chess players in the Tang Dynasty include Xuanzong Wang, Wang, Gu Shiyan and Xinzong Slip. Due to the implementation of the equal trust system, the influence of Go has been expanded and the social status of chess players has been improved. This system lasted for more than 500 years from the early Tang Dynasty to the Southern Song Dynasty, which greatly promoted the development of Go in China.
