Description

Hectochess Chess is a 10x10 chess variant invented in A. M. DeWitt. You'll find more details on the game's chessvariant page.

Rules

Initial setup

The board has 10 x 10 squares.

Pieces

Champion

The Champion leaps two spaces in any orthogonal or diagonal direction, or one space in any orthogonal direction. It is a compound of the Alfil, Dababbah, and Wazir. It was introduced in Omega Chess, and it moves the same as it does in that game.

Wizard

The Wizard moves one space diagonally or leaps to a space one file and three ranks away or three files and one rank away. It is a compound of the Ferz and the Camel. It was introduced in Omega Chess, and it moves the same as it does in that game.

Marshall

It combines the move of Rook and Knight. It can be found in many, many chess variants since Carrera, Bird, Capablanca and many others like Grand Chess or Gothic Chess. (under many other names: Champion, Guard, Empress, Concubine, Chancellor, etc. The later is sometimes preferred, however it is confusing since Capablanca used it once for R+N and once for B+N. It is an Elephant in Seirawan Chess).

Archbishop

It combines the move of Bishop and Knight. It can be found in many, many chess variants since Carrera, Bird, Capablanca, Modern and many others like Grand Chess or Gothic Chess. (under many other names: Centaur, Minister, Equerry, Janus, Archbishop, Princess, Chancellor, etc. It is a Hawk in Seirawan Chess).

Leo

The Leo moves as a Queen but must hop over an intervening piece to capture.

King

Moves as in usual Chess but castle 2 or 3 squares away with the rook.

Queen

Exactly as in usual Chess.

Bishop

Exactly as in usual Chess.

Knight

Moves as in usual Chess.

Rook

Exactly as in usual Chess.
