Rotary Chess

In my parlance, a "rotary counterpart" to a piece is one whose move turns its move by 45 or 90 degrees. For example, the Bishop and Rook are rotary counterparts, as are the Wizard and Sorcerer, and of course the Ferz and Wazir, and the Alfil and Dabbabah.

In my wandering through the world of fairy chess pieces, I've come across a few that should have a rotary counterpart, but don't (as far as I could find). So, I created the counterparts.

This game features those pieces.

Pieces

This game uses all of the orthodox pieces except the Knight; that leaves the King, Queen, Bishop, Rook, and Pawns. They all move as they do in orthodox Chess.

The other pieces include:

Basilisk (counterpart to Frog): moves one space orthogonally, or leaps three spaces diagonally.

Caballero (Calatravan Knight; counterpart to Teutonic Knight): moves one space diagonally, or leaps (1,2) or (2,3).

Jackal (counterpart to Leon): Leaps three spaces diagonally, or (2,3)

Mongoose (counterpart to Snake): Moves one space left or right, then may slide diagonally from there like a Bishop.

Sniff (counterpart to Fibnif): Moves one space diagonally, or makes a sideways (1,2) leap.

Thaumaturge (compound of Wizard and Sorcerer): Moves to any adjacent space, or leaps (1,3) or (2,3).

Walrus (counterpart to Dolphin): moves up to three spaces diagonally, but can only leap to the second or third space if not capturing.

Rules

Except where noted otherwise, the usual rules of orthodox Chess apply.
