Some Asian chess boards include also diagonal lines or dots on top of their

horizontally)

On Go boards, the grid cells are definitely rectangular, not square. The
reason for this is that boards are usually looked at at an angle, and
having the cells be higher than wide makes them appear (close to)
square. However, because diagrams are usually viewed at close to a right
angle, Go diagrams use squares, not rectangles.
