Rectangular Cubic Chess
Rectangular Cubic Chess is a 72 square variant where extra eight squares are at the top and base of the board. The board rotates and pieces are the same as orthodox chess. The additional squares at top and base open up the board and allow for potentially infinite movement in almost any direction. The image on the left with knights and rooks shows the reverse side to the image on the right. All pieces move the same as orthodox chess with adaptations to the board.
These images above demonstrate movement of knights and bishops. Unlimited movement for bishops if unimpeded by other pieces.
To the left shows how diagonal movement on the top
four squares (applies to the bottom four as well) is
limited to that side of the board one square diagonally.
On the left shows how the rook can move around the board
forward, backward and across.
Queen can move forward, backward, across and diagonally.
Pawns move the same as orthodox one square forward or
two forward on the first move and one square diagonally
forward to take including diagonally to another side.
Pawns also retrieve taken pieces upon reaching the
opponents side of the board.
