Assimilation Fusion Chess

by Fergus Duniho

Assimilation Fusion Chess is hybrid of Assimilation Chess and Fusion Chess. In this game, simple pieces can combine with pieces of either side to form new compound pieces, and compound pieces can split into simple pieces. It differs from Fusion Chess by letting you assimilate enemy pieces, and it differs from Assimilation Chess by letting you combine your own pieces. It adds to Fusion Chess the ability to increase your forces by capturing enemy pieces, but not in the straightforward Shogi-like way that Fusion Chessgi does.

Setup

The initial setup for Assimilation Fusion Chess is exactly the same as for regular Chess. So there is no need for a diagram.

Rules

Assimilation Fusion Chess is played like FIDE Chess with the following exceptions:

Pieces


King
The King moves one space in any direction, but may not move into check. The King is one of four possible royal pieces which a player may have. A King may merge with a Bishop to form a Pope, with a Rook to form a Dragon King, or with a Knight to form an Eques Rex. If any one of these pieces gets checkmated, you lose.

Pope
The Pope moves as a King or Bishop, but may not move into check. The Pope is a royal piece and is formed when a King merges with a neighboring Bishop. When the Pope is on the board, it is the player's only royal piece, and the game is lost if it is checkmated. The Pope may split into its components by making a non-capturing move with one of them.

Dragon King
The Dragon King moves as a King or Rook, but may not move into check. The Dragon King is a royal piece and is formed when a King merges with a neighboring Rook. When the Dragon King is on the board, it is the player's only royal piece, and the game is lost if it is checkmated. The Dragon King may split into its components by making a non-capturing move with one of them. The name for this piece is borrowed from Shogi.

Eques Rex
The Eques Rex moves as a King or Knight, but may not move into check. The Eques Rex is a royal piece and is formed when a King merges with a neighboring Knight. When the Eques Rex is on the board, it is the player's only royal piece, and the game is lost if it is checkmated. The Eques Rex may split into its components by making a non-capturing move with one of them. The name is Latin for Cavalier King.

Knight
The Knight moves as the Knight in Chess, jumping in an L shape, two spaces forward and one to the side. A Knight may merge with a Rook to form a Marshall or with a Bishop to form a Paladin.

Rook
The Rook moves as the Rook in Chess, any number of spaces orthogonally. A Rook may merge with a Knight to form a Marshall or with a Bishop to form a Queen.

Bishop
The Bishop moves as the Bishop in Chess, any number of spaces diagonally. A Bishop may merge with a Knight to form a Paladin or with a Rook to form a Queen.

Queen
The Queen moves as the Queen in Chess, any number of spaces in any single direction. The Queen is a combination of Rook and Bishop. It may separate into its components by moving one of them to an empty space.

Marshall
The Marshall moves as a Rook or Knight. The Marshall is a combination of Rook and Knight, and it may separate into its components by moving one of them to an empty space.

Paladin
The Paladin moves as a Bishop or Knight. The Paladin is a combination of Bishop and Knight, and it may separate into its components by moving one of them to an empty space.

Pawn
The Pawn moves as the Pawn in Chess. It moves forward one space, but is allowed a double move on its first move. A Pawn captures by moving one space diagonally forward. If a Pawn makes a double move to a space alongside an enemy Pawn on its fifth rank, the enemy Pawn may capture it by en passant. Upon reaching the last rank, a Pawn may promote to a Rook, Bishop, or Knight. It may not promote to a Queen, Marshall, or Paladin.

Notation

Use algebraic notation as you would for Chess. Use P to denote Paladin and M to denote Marshall. Denote Pawn moves without the use of any letter to identify it. When a piece merges with another piece, follow the move with = and the abbreviation for the new piece. For example, R a4 - d4 = M indicates that a Rook moved from a4 to d4 and merged with a Knight on d4 to form a Marshall. When a piece separates from a compound piece, identify the move as belonging to the piece which moves away from the compound piece. Follow its move with a semicolon and identify what piece is left behind. For example, R a4 - d4; a4 = N indicates that a Rook moved to d4, separated from a Marshall at a4, and left a Knight behind at a4.

Equipment

You can play this game with the pieces from a regular Chess set, a Gothic Chess set, or a Grand Chess set. If you use a regular Chess set, you should use a pair of pieces to represent each compound piece. One regular Chess set will have all the pieces you need for this. Sets for Gothic Chess and Grand Chess come with additional pieces that represent all the non-royal compound pieces in this game. But you would still have to use pairs of pieces for the royal compound pieces.

Play on Your Computer

You may play Assimilation Fusion Chess on your computer with Zillions of Games. In April 2001, the board was updated to the one shown on your left. It is made from computer generated textures. This board combines elements of the boards for Fusion Chess and Assimilation Chess. Sound effects were also updated, there was a slight rule change, and the code was optimized a bit.
