Both players need to place six neutral pieces within an 8x8 square, with each player having three pieces. The first piece of each player must be placed in the central 4x4 area, while the second and third pieces must be placed on the sides but not on the two squares at the corners (meaning there are four squares in the middle of each side where pieces can be placed). It is required that all neutral pieces cannot be collinear (on the same horizontal or vertical line) and cannot be connected diagonally. How should this ludeme be written?

Afterwards, the first player chooses a corner to place Rook, and the opponent chooses the opposite corner to place Rook. There are three available spots to place the Rook on each corner and they can choose any of them. Then, players take turns placing a Pawn on any empty site.
