This game has two problems. First there is the perennial problem with
symmetry about square centres: the Bishops are confined to the same group
of squares. Secondly it does not as promised use only the standard chess
set. There are nine Pawns per side (assuming the f8 Pawn a misprint). My
first thought for solving this was to remove the b8 and h2 pawns and
reverse Bishop and Knight on the Queen's side. Then I had a better idea:
leave the Bishop and Knight, strip out the long diagonals, and close up
the board to 8*8, putting the Kings in opposite corners. This would allow
the standard board as well as set can be used. Below are two versions, one
rotationally symmetrical (like the 9*9), the other symmetrical about the
empty diagonal.
