InfoChess is a game played on a standard chessboard with standard chess pieces, but with the addition of information warfare (IW) moves. The game is designed to stimulate a deeper appreciation of the interaction between the informational domain and more traditional military affairs.
The game becomes available to set up and play when both the Black and White positions are filled by players.
Each player simultaneously determines the pieces it will use in the game. Each player is given 10 points. Kings are free and each player gets one. Queens cost 3 points; Knights and Rooks cost 2 points; Bishops and Pawns cost 1 point. Players can buy up to one Queen; up to 2 each of Knights, Rooks, and Bishops; and up to 8 Pawns.
Pawns can be placed anywhere on the second row. All other pieces can be placed anywhere on the back row. If two bishops are purchased, they must be placed on different colors.
Kings, Pawns, and Knights start off as invisible to the opponent.
Queens, Rooks, and Bishops are visible.
Each player receives 10 IW points that it can use during the course of the game. Players must decide before the game starts how they will allocate their points between two types of IW moves: Psyops and Electronic Warfare.
- Psyops essentially force an opponent's piece to surrender. Psyops capture the pawn furthest from the King. (This is measured by the number of moves it would take the King to get to that piece). If the opponent does not have any pawns, the furthest remaining piece is removed. Kings can be captured using Psyops if they are the last piece.
- Electronic Warfare essentially disrupts the opponent's ability to communicate to its units. Electronic Warfare prevents the opponent from making its next physical move.
- All pieces move according to standard chess rules, unless otherwise noted.
- The game ends when the King is captured.
- White moves first. Sides are determined randomly.
- Notification, if applicable, of whether the player's previous IW move was defended or not.
- Notification, if applicable, of opponent's IW move (but not whether it was reinforced or a feint).
- Option to defend against opponent's IW move and notification of success or not.
- Option to ask about "pawn-capture" (see below)
- Required physical move
- Option to make one offensive IW move, either Pysop or EW but not both
