This is a variant inspired by Tamerlane Chess. It features promotable pieces with leaper movements: the Rhinoceros, the Griffon, the Emir (also known as the Osprey), the Ship, and the Snake.
The first step is to choose a set of additional pieces to vary the game.
In this version, the board is now 12 x 10 squares.
Initial Position for Wild Babur, one of the possible variant :
Moves one square diagonally and then, goes away of an indefinite number of cases vertically, never horizontally. It can move one square diagonally only. It can not jump and must begin its move with the diagonal step. The Ship can promote to Griffon.
Moves one square diagonally and then, goes away of an indefinite number of cases vertically or horizontally. It is authorized to go only one square diagonal. It can not jump and the unobstructed path must start with the diagonal movement.
Jumps at 2 squares. The Squirrel can promote to Lion.
It jumps on any square situated at 1 or 2 squares distance from where it stands.
Moves one square vertically and then, slides away of an indefinite number of squares diagonally. The Ship can promote to Rhinoceros.
It moves one square vertically or horizontally and then, slides away of an indefinite number of squares diagonally.
It moves 1 or 2 cases orthogonally, jumping over the first case if it is occupied. Then, it combines the moves of old Dabbaba and Wazir found in ancient Muslim Chess variants. In this game, when the Machine reaches the last row it promotes to a Lion. The Machine can promote to Emir.
leaps to the second square orthogonally (the Dabbaba's leap), then slides outward diagonally like the Bishop.
it is another compound piece that moves as a Rook or a non-royal King. That means that it is a Rook that can also step one space diagonally.
Moves one or two squares diagonally. When an Elephant moves two squares, it is allowed to jump, i.e., the intervening square does not have to be empty. The Elephant moves as the combined Alfil and Firzan (Ferz) from Shatranj, two pieces which were also present in mediaeval Chess and have disappeared with the birth of modern moves for Queen and Bishop.
As in Metamachy, a well known piece from medieval Muslim great Chess like Tamerlane's Chess. It jumps to the opposite case of a 2x4 rectangle, like an extended Knight. No matter what intermediate cases contain. Note that it always stays on the same color of square.
moves without taking like a Rook, but it takes by going in a straight horizontal and vertical line and jumping over exactly one piece. When a Cannon takes a piece, there must be exactly one piece between the original and final square of the Cannon's move - this piece may be of either color. (This is identical to the move of the Cannon in Xiangqi.)
A non-royal King who moves and captures one square in any direction, but without being hindered by check. Like the Pawn, he can also move without capturing to the second square straight ahead, and like the Pawn he can be captured en passant on the square he crossed. When he reaches the last row it can promote to Queen.
Moves and captures as in usual Chess, and promotes to Queen, with one difference: on this 12x12 board a Pawn may take its two-square step from any square it stands on, not only from its starting rank. It still cannot jump, so a piece in front of it stops it, and it can still be captured en passant on the square it crossed.
Moves as in usual Chess, except there is no castling.
Exactly as in usual Chess.
