Chess generalized to higher-dimensional 8n boards. This 3D version is an 8×8×8 board with legal move generation, check, checkmate, and stalemate.
Coming soon: n = 4 visualization using eight connected 3D boards.
I designed an extension of standard chess notation for boards of any dimension. The square of action starts with a letter a–h, has one number 1–8 for each middle dimension, and ends with a letter a–h so the dimensionality is visible from the square name.
Example: Qxf7+ in 2D becomes Qxf7a+ in 3D, where f7a is the square.
Example: b8301c describes a square on a 6D board.
Regular 2D chess is identified by two letters instead of letter-number. Example: f4=Q becomes fd=Q.
