The game and rules of chess

The play and rules of chess are as follows:

The place where the chess pieces move is called a chessboard. On the rectangular plane, there are nine parallel vertical lines and ten parallel horizontal lines intersecting, and there are * * * ninety intersections for placing chess pieces. The blank area without vertical lines between the fifth and sixth horizontal lines in the middle is called "river boundary".

The whole chessboard is divided into two equal parts by the "river boundary"; The place where the two generals sit, where the word "rice" is painted, is called "Jiugong". There are thirty-two pieces * * *, which are divided into two groups, red and black, with sixteen pieces in each group. Each player holds a group, and each group has the same arm and is divided into seven types.

Red: Shuai (1), Shi (2), Xiang (2), Che (2), Ma (2), Cannon (2) and Bing (5); Black side: general (1), soldier (2), elephant (2), car (2), horse (2), cannon (2) and pawn (5). Among them, handsome and general, official and scholar, phase and image, soldier and pawn have exactly the same function, just to distinguish bonus chess from black chess.

China chess originated in China, which is an ancient board game with a history of about two thousand years. It is a classic product of intangible culture of Chinese civilization. Dr Joseph Needham, a famous British scholar, clearly pointed out in China's History of Science and Culture that chess is also the creation of China people.

He analyzed in detail the relationship between China's ancient game-Liubo and astronomy, symbolism and mathematics. He said: "Only in China, the prevalence of Yin-Yang theory promoted the emergence of the embryonic form of chess, invented astronomical divination, and then developed into a game with military significance."

The word chess first appeared in the Warring States Period. "Chu Ci Evocation" made a special record of its shape and play: "There are six books in chess; Go hand in hand with the camp, and the road is forced; When you become a cockroach, you will seek it and you will be white. " In other words, jade (that is, castor) is equivalent to dice.

(referring to two teams or two teams must fight), attack each other and force each other to death; Finally, the winner seeks victory. Defeated the enemy soldiers (five men in the military system in the Spring and Autumn Period) and gave a cheer of victory.
