What hand muscles and formulas must I know about Go?

Hand tendon and formula in Go are two important concepts in Go. Hand tendon refers to making one's chess pieces more stable on the chessboard through some specific techniques, so as to better control the situation. Formula refers to a conventional way of playing chess, which is summarized from the previous experience of Go.

Here are some common Go players' muscles and formulas:

-Star pattern: put two pieces in the center of the black edge and three pieces around the white edge.

-Small-eye formula: the black side plays a chess piece in the center, and the white side plays three chess pieces around.

-Big-eye formula: black hits three pieces in the center and white hits four pieces around.
