Turkish Great Chess, variation V
By John Ayer
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 Rhinoceros combines the powers of Bishop and Knight.
- The Gazelle leaps one square diagonally and two orthogonally; that is, it leaps to the opposite corner of a rectangle two squares by four.
- The Great Ferz moves one square diagonally and then three or more orthogonally, not leaping.
- The Pawns have only single moves.
The Pawn promotion rule is unknown. There is no castling, and a stalemated player loses.
