China chess formula table

China chess formula table is introduced as follows:

Basic walking formula:

A horse walks in the sun like a field. The car went straight and sped over the mountain. Take diagonal lines to protect the generals. The chess pieces will never come back.

Advanced walking formula:

General Tanaka left anyway and became a loser if he was eaten.

Scholars walk sideways to protect the generals from going far.

Walking sideways like a field, a son can't walk in the field.

The word "pony day" goes sideways, and you can't go straight with your son.

The old car lets you go for free, and whoever eats it is called the first brave.

Anyway, the cannon can move, and the opponent can only be eaten by the spacer (meaning that the cannon moves in the same way as the car, but it can only be eaten by the spacer).

The team can only go forward and cross the river to control it.

When you meet your opponent on the road, you should prevent him from walking while eating.

A man-eating general is called a general, and losing chess is a good hand.

Chessboard:

The place where the chess pieces move is called a chessboard. On the rectangular plane, nine parallel vertical lines and ten parallel horizontal lines intersect, and * * * has ninety intersections. ?

Chess pieces are placed at the intersection. The middle part, that is, the blank area without vertical lines between the fifth and sixth horizontal lines of the chessboard, is called "River Boundary". In the middle of China's chessboard, there is often a gap with the words "Chu River" and "Han Boundary" written on it, which is the "Chu-Han War" in the history of chess.

According to historical records, the "Chu River Han boundary" was located in Xingyang and Gaoping in ancient times, with the Yellow River in the north, Mangshan Mountain in the west, the plain in the east and Songshan Mountain in the south, which was a battleground for military strategists in past dynasties. In 203 BC, Liu Bang sent troops to attack Chu, and Xiang Yu was short of food and soldiers, so he was forced to put forward the requirement of "dividing the world, cutting the gap for Han in the west and Chu in the east". Since then, there has been a statement from the Chu and Jianghan circles.

There are still two ancient city ruins in Guangwu Mountain of Xingyang, one in the west is called Hanwang City, and the other in the east is called Bawang City, which is said to have been built by Liu Bang and Xiang Yu. Between the two cities, there is a big ditch about 300 meters wide, which is what people usually call the gap, and it is also the basis for marking the boundary river on the chessboard. ?

The square between the two ends, that is, between the fourth and sixth vertical lines at both ends, is called "Jiugong" (with exactly nine intersections), which symbolizes the military account. ?

The whole chessboard is divided into two equal parts by the river boundary. In order to record the game and learn chess, the current rules stipulate that each vertical line in the red side is represented by chinese numerals 1 to 9 from right to left, and each vertical line in the black side is represented by Arabic numerals 1 to 9. Our own chess pieces always use their own line numbers, regardless of whether the chess pieces "cross the river".

Before the game starts, the red and black sides should put the chess pieces in the designated position. Every step of any chess piece, walking sideways like a car, writes "advance", "retreat" and "flat".
