What's the use of the stars on the board of Go?

The nine points on the chessboard can all be called "star positions", which are composed of 19 parallel lines with equal distance and perpendicular intersection. Form 36 1 intersection points, referred to as "points". The overall shape of the chessboard and the transverse direction of each grid are slightly shorter, generally 2.4 cm: 2.3 cm per grid. In ancient China, it was called "Tai Chi Map", but in modern times, it follows the Japanese nomenclature. The biggest role is to facilitate positioning. With it, it will be much more convenient for you to find small, high, off-site and third-class positions, especially for those with more skilled skills, which will play a great role in grasping the bureau.
