Wouldn’t checkering itself, even in the abstract, need to reference two discernible colours or shades, and so, wavelengths of light, and so, some extension along a z axis, and position in time? Is it possible even for an abstract checkered pattern to be defined in any less than 3 dimensions + time?
Factoid; all chess games are technically 4D.
You can argue 3D pieces + time but in the abstract the board only uses two dimensions
