The origin and development of gobang?

It is said that Huangdi, the ancestor of the Chinese nation, inadvertently drew 17 horizontal lines and 17 vertical lines. This unintentional invention created gobang. As early as 595 AD, the ancients used porcelain to burn gobang plates.

The ancient gobang chessboard and Weiqi chessboard are universal. Seventeen-way (17× 17) chessboard was used in the Han and Wei Dynasties, and nineteen-way (19× 19) chessboard was popular in the Southern and Northern Dynasties. It was not until 193 1 that the so-called gobang appeared. The shape is close to a square, and 15 parallel lines are drawn horizontally and vertically on the plane. The lines are black, forming 225 intersections. The distance between two adjacent intersections is about 2.5 cm in the vertical line and 2.4 cm in the horizontal line.

The horizontal lines at both ends of the chessboard are called end lines, and the outermost two longitudinal lines on the left and right sides of the chessboard are called sideline lines. Four points that develop from two end lines and two side lines to the center and intersect with the fourth line are called "stars". Tianyuan and Xing should be marked with solid dots with a diameter of about 0.5 cm on the chessboard.

The reform of Japanese gobang:

Gobang is a popular board game in heian period. Since 1899, Japanese chess players have proved that Gobang with original rules will win first, and Gobang has entered a road of continuous improvement. After decades of revision, verification and revision, Gobang was finally developed and publicly named Gobang, so rules were formed in Japan, also known as Japanese rules or. The original rules are still being played in China, which are also called no-prohibition rules and free rules. With software verification, the black hand will win.

Decades have passed, and people find that it is still impossible to completely balance the advantages of Kuroko. Therefore, the "RIF rule" used in international competitions, based on the gobang rule, adds three-handed exchange and five-handed two-playing, which is the first gobang professional rule that can truly meet fair competition.
