This is a large Chess variant using three new pieces, the Rhinoceros, the Gazelle, and the Great Ferz. The inventor is unknown.
The board is thirteen squares by thirteen, uncolored (it is checkered in this graphic for ease of illustration). White's first rank (and probably Black's, too), left to right, is Rook, Knight, Bishop, Rhinoceros, Gazelle (here illustrated as a Giraffe), Great Ferz (here illustrated as a Chancellor), King, Queen, Gazelle , Rhinoceros, Bishop, Knight, Rook. The Pawns are placed on the fourth rank, and have only single moves.
The Pawn promotion rule is unknown. There is no castling, and a stalemated player loses.
