Abduction Chess

Created by W. D. Troyka, November 2000


The rules of standard chess apply, with one minor exception:
An alien spacecraft is hovering over the board, making random moves after every round and occasionally abducting pieces, which are never seen again. The Alien moves like a Queen, except that it cannot be captured and it does not attack the King. It blocks movement by the pieces.

You win by capturing the King, not by checkmate. The King can move into check.

Alapo

Implemented by Matthew Burke.

This chess variant was invented by Johannes Tranelis in 1982. It was mentioned in a German book Spiele fur Zwei (Games for Two), and later in Pritchard's Encyclopedia of Chess Variants.

Be the first player to get a piece in the opposite endzone. You may only move a piece into the endzone, however, if it starts its move on the opponent's back row. The Queen, Rook, Bishop, and King move as in chess. The Minister (upside-down Bishop) moves one step diagonally. The Dignitary (updisde-down Rook) moves one step orthogonally.

Alekhine Chess

Invented and implemented by Michael Wortley Nolan, August 2002


Alekhine Chess is named in honor of Alexander Alekhine, World Chess Champion 1927-1935, 1937-1946.

Alekhine Chess is a variant of traditional chess, played on an 8x14 board. The object of the game is, like traditional chess, to checkmate the opponent. Both players start the game with 28 pieces consisting of 14 Pawns, two Rooks, two Knights, two Bishops, two Cardinals, two Marshalls, two Queens, one General, and one King.

To the group of traditional chess pieces are added the following:
Cardinal = Knight + Bishop
Marshall = Knight + Rook
General = Knight + Bishop + Rook

The Pawn, Knight, Bishop, Rook, Queen, and King all move and capture in the same manner as in traditional chess. The General moves and captures like a Rook or a Bishop or a Knight. The Marshall moves and captures like a Rook or a Knight. The Cardinal moves and captures like a Bishop or a Knight.

When castling, the King moves to the square next to and on the inside of the Rook, then the Rook moves to the square next to and on the inside of the King.

Pawn promotion (to any one of the seven pieces) and en passant capturing are the same as in standard chess.

The Notation variant consists of Alekhine Chess with a rank and file notation key.

Please note: Alekhine Chess requires Zillions of Games version 1.3.1 (or higher).

Alice Chess

Invented by V.R. Parton, 1953.
Implemented by Pierre Tourigny, August 1999.

Alice Chess is a popular variant where the pieces, like Lewis Carol's heroine, go "through the looking glass" to a Mirror board and then back to a Normal board. Curiouser and curiouser, you can use a single board to represent the Normal and Mirror boards at the same time.

The file contains five variants:

Alice Chess The variant invented by V.R. Parton in 1953
Alice Mirror Black pieces start on the Mirror board
Alice Zero Pieces can switch board while staying on the same square
Alice Grand An Alice version of Christian Freeling's Grand Chess
Alice Extinction An Alice version of Extinction Chess

Game: Anti-King Chess

Invented and implemented by Peter Aronson, January 2003.

Anti-King Chess is a variant that adds an Anti-King to the standard set of pieces used in FIDE Chess, and replaces the Pawns with Berolina Pawns.
An Anti-King is a King that is in check only when not attacked by opposing pieces. The goal of Anti-King Chess is to checkmate either your opponent's King or Anti-King.

Anti-Kings move like Kings, but can only capture friendly pieces. Being a form of King, Anti-Kings may not be captured, only mated. Anti-Kings do not offer check to friendly Kings. Kings do not attack Anti-Kings.

There is no castling, but Kings may make an Knight's leap to an empty square for their first move. Anti-Kings also get this move.

The primary feature of this game is the dynamic tension between protecting your King and keeping your Anti-King under attack.

Game: Assimilation Chess

Game and zrf implementation by Fergus Duniho Copyright © 2001


Assimilation Chess combines elements of Fusion Chess and Chessgi. Unlike Fusion Chessgi, which is a straightforward hybrid of these two games, Assimilation Chess slightly changes the rules of Fusion Chess to create a game in which you can add to your own material by capturing enemy pieces. Instead of holding onto a captured piece for future deployment, you assimilate the captured piece into the capturing piece whenever the two pieces are non-identical simple pieces. For example, a Knight that captures a Rook becomes a Marshall, or a Rook that captures a Bishop becomes a Queen. When a simple piece captures a Pawn or a compound piece, or when a Pawn or compound piece captures anything, the capture does not change the capturing piece.

The game's name is inspired by the Borg from Star Trek, who regularly increase their numbers by assimilating their enemies.
The object is the same as it is for Fusion Chess, to checkmate your opponent's current royal piece.

The board was made from computer generated textures.

Game: Assimilation Fusion Chess

Game and zrf implementation by Fergus Duniho Copyright © 2001


Assimilation Fusion Chess is a hybrid of Fusion Chess and Assimilation Chess. As in Fusion Chess, players can combine their simple pieces into compound pieces. As in Assimilation Chess, simple pieces assimilate other simple pieces when they capture them. And, as in both Fusion Chess and Assimilation Chess, compound pieces can split into their component simple pieces.

The board is made from computer generated textures. It combines elements from the boards for Fusion Chess and Assimilation Chess.

Game: Benedict Chess

Created by W. D. Troyka, February 2001


Standard chess rules apply, except:

There is no capturing.
At the end of a move, all enemy pieces attacked by the moving piece (under normal chess rules) are flipped to become friendly pieces.
You win by flipping your opponent's King.
In the variant, a promoted piece does not flip opponent pieces on the same turn as the promotion.

Benedict Chess is a wild game of rapidly shifting alliances. Initiative is everything. You must move your pieces to attack enemy pieces and establish a presence near the enemy King as soon as possible. Because there is no capturing, the full complement of 32 pieces remains on the board at all time, and the game is strictly positional.

Flipping the opponent's array pawns is not as advantageous as may first appear. Because they cannot capture, flipped pawns can serve as shields preventing (only for a moment) flipping of the opponent's royal pieces. This neutralizes White's opening advantage and allows for balanced play.

Games are fast and violent, seldom lasting over twenty rounds. It does not appear that either player has a calculable forced win.

(Note: For anyone interested, Abduction Chess has recently been revised to include four new variants, a new board design, and new sound effects. In the variants, the Alien randomly releases abductees back onto the board.)

Updated 12/21/02
Board switching implemented in Zillions v2 style (game still works in Zillions v1).

Game: Better Pawns

Invented and implemented by Karl Scherer, June 2000


Object: Checkmate the opponent's King.

All standard chess rules apply, plus the following: Variant 1 The Pawns can also move sideways, but they capture only forwards as usual.
Variant 2 The Pawns can also move sideways and backwards.
Variant 3 As variant 1, plus: apart from promoting on the far rank, pawns on files a to d promote on the h-file, the Pawns on files e to h promote on the a-file.
Variant 4 The Pawns can also move sideways and backwards, promote sideways, too.
Variant 5 thru 8 are similar to variants 1 thru 4, but the Pawns can also capture in direction NEE and NWW.
Variant 9 is standard chess plus this extended NEE, NWW capturing feature.
Variant 10 thru 13 are similar to variants 1 thru 4, but the Pawns can only capture forward. There is no En Passant.
Variant 14 thru 27 are similar to variants 1 thru 13, but the Pawns can also move 2 steps at any time. En passant capture is possible after these 2-step moves.

The game 'Better Pawns' was born from a desire to have more powerful Pawns in chess. Also, variants 3 and 4 make the otherwise rare event of pawn promotion a more frequent one.

Game: Big Battle

Big Battle © 1994 by M K Morrison
BigBattle.zrf © 1999 by David Milne


Introduction

Big Battle ( Big Bat for Short ) follows in the great tradition of Chess. M K Morrison invented Big Battle in 1994. The game was-fined to its final form in 1998. The first years of its creation involved play testing against International Chess Master Ortvin Sarapu (twenty time New Zealand Chess Champion). The final rule change came at the suggestion of the then New Zealand Champion Alexei Kulashko. Big Battle used Chess as a starting point but it becomes a different game. Chess players, even children, have found Big Battle an easy game to pick up.

Description

Big Battle is played on a 10 by 10 chequer board of a hundred squares. Because of the enhanced size of the Big Battle Board, the Big Battle counterpart of the Chess Pawn, called a Soldier ( Sol for short) has the option of moving three squares, two squares or one square forward. Unlike the Chess pawn the Big Battle Soldier has these options not only on its first move but throughout the game. The en-passant rules of Big Battle allow capture by en-passant whenever an enemy Soldier on an adjacent file attempts to sneak past by moving two or three squares. The other big difference seen in Big Battle consists of a new and powerful piece called the Prince. The Prince combines the power of the Chess Knight and the Big Battle Queen. But the Big Battle Queen itself has greater powers than the Chess Queen. In addition to the traditional powers of the Chess Queen the Big Battle Queen can jump over an immediately adjacent piece (but cannot move like a Knight). The Big Battle King has the ability to move two squares. He also, can jump over an immediately adjacent piece. The Big Battle Knight has the option, while positioned on its back rank of making a double Knight move, known as the double Knight hop, providing that no piece occupies the intermediate square of this manoeuvre. The Big Battle Bishop moves exactly the same way as the Chess Bishop. Off course the enhanced Big Battle chequer board gives it more squares to move to. All Big Battle pieces, except for the Bishop, have greater powers than the corresponding traditional Chess piece.

Game: Black Hole Chess

Invented and implemented by Karl Scherer, May 2000


Black Hole Chess
Object: Checkmate the opponent's King.

There is no fight for the centre in this variation of chess! Any move that would go to d4/d5/e4/e5 moves the piece from the board. However, it can be re-inserted into the game at any later time.

Note that you cannot really move a piece to the centre; you may move it off-board right away if the chance arises.
To reinstate a piece, just click on an off-board piece.

The motivation behind the 'black hole' in the centre is to avoid the typical struggle in standard chess to occupy the centre. Furthermore the re-insertion of pieces adds some new excitement to the game.

Black Hole Chess - Swap Variant
The Swap Variant is like Black Hole Chess, but only the latest piece that fell into the black hole is stored.

Game: Bottleneck Chess

Created by Koksal Karakus, March 2001


Bottleneck Chess is a chess variant designed for the 41 Squares Contest in http://www.chessvariants.com by Koksal Karakus in 2001.

Other than that, the only difference from the usual chess is the movement of the pawns. Here the pawns move one square in the NW direction for white or one square in the SE direction for black (diagonally). Pawns can capture one square in the N or W direction for white, or one square S or E direction for black (orthogonally).

One thing to note is that Knights cannot jump to a square if all of the three squares between them are outside the board, which for example applies to the inner Knight at the beginning of the game.

There is no en-passant rule or castling.

The aim is to checkmate to opponent's King.
