Weiqi, a strategic two-player board game, was called "Yi" in ancient China and "Go" in the West. Popular in East Asian countries (China, Japan, Korea, North Korea), is one of the four arts of piano, chess, painting and calligraphy. Weiqi originated in China and was written by Emperor Yao. It was recorded in the Spring and Autumn Period and the Warring States Period. In the Sui and Tang dynasties, it was introduced to Japan through Korea and spread to Europe and America. Weiqi contains the rich connotation of Chinese culture, it is the embodiment of Chinese culture and civilization.
Go, chess board
Go uses a square checkerboard and black and white round pieces to play, there are 19 lines on the board and the board is divided into 361 crossing points, the pieces walk on the crossing points, the two sides alternate chess, can not move after the drop, to surround the more ground to win. Because the black side took advantage of the first, it was artificially stipulated that the black side should give the white side a post at the end of the game. In ancient Chinese Weiqi, the black and white sides place two pieces at the diagonal star position (diagonal star layout), which is the seat son system, and the white side first. Modern Weiqi developed from Japan, cancelling the seat son rule, black first and white later, making the changes of Weiqi more complex. Go is also considered the most complex board game in the world.
Counting (comparing) method: expressed in simple words, it is to calculate and compare the number of areas surrounded by the two sides in the final game, and to judge the outcome by the number of eyes, the Japanese and Korean Go rules all use the counting method. The Chinese Weiqi rules use the number method.
The number method is based on the number of pieces on the board to determine the outcome of the game after the end of the game. Because the counting method only calculates the number of territorial items, the completion of the single official does not affect the outcome of the game, so it is stipulated that the final game does not collect the single official. Therefore, whether all the single officials have been collected is the main difference between the counting method and the counting method at the end. The so-called return number is the basic outcome standard of exponential submethod. Because a standard Go board has a total of 361 intersections, each side of the game should have half of the total points, or 180.5 points. More than this number wins, less than this number loses, equal to this number of sum.
