ZOP Chess

This is a very rough outline of a chess-style game. The pieces and their movements are described below:

King

• Moves only one square at a time.
• Cannot move adjacent to an opponent's king unless the player's king is on a rotator, in which case it can move one square. If a queen is present, standard movement rules apply.
• Capture occurs only under specific conditions.

Queen

(Movement rules to be specified)

Rook (Fortress)

• Cannot move independently; another piece must be present on the same circle.
• Active only when another piece is immediately adjacent (not necessarily on the same rotator).
• Cannot move with an opponent's rook. This exception does not apply to the king (one move) or queen (three moves).
• Captured by the king and queen (possibly involving a change of position).
• Can be captured by another rook with stronger support.

Bishop (Cannon)

• Moves in a straight line with a specific cadence (1, 3, 2, 2, 1, 1…), where the number represents the distance from the bishop.
• Cannot shoot over its own pieces or opponent's pieces, except when positioned immediately behind a rook, in which case its shooting range doubles in the direction of the rook.

Knight (Rider)

• Moves one or two squares on its rotator.
• Can move over its own pieces or opponent's pieces.

Pawn

• Moves freely; has one point value.

Castling

• An entire rotator containing six pieces can be exchanged for an empty rotator.
• This can be done only once per game.
• Alternatively, it can be done multiple times, but only after the opponent has castled.
