Secret Intelligence Chess

For a long time, I did not support any incomplete information games in [Game Courier](/play/pbm/), because it normally makes complete information about the game publicly available. With the idea of enabling it to support incomplete information games like Kriegspiel or Dark Chess, I started working on my own incomplete information game that would rely on the capabilities of Game Courier and its GAME Code programming language to hide certain information from each player. I started by working on Hidden Identity Chess, in which the players could see each other's pieces, but they couldn't see what they were. Since an effective way of hiding pieces was to remove them from the board, I switched to working on a game I called Hidden Danger Chess, in which you could not see where your opponent's pieces were. Finally, I added elements of disinformation into the game and changed its name to Secret Intelligence Chess, as the game involves gathering intelligence on what and where your opponent's pieces are. While this game could be played with a human referee who knows the complete position and can tell players which moves are legal, it is designed for a computer program to run the game, and it will run more smoothly this way.

Setup

This is an unequal armies variant in which each player may end up with a different army. The program or referee should first pick a random number between 1 and 4. A human may do this with a four-sided die. Do this for each side separately. The setup is determined randomly. This may be done by a computer program or by a human referee who uses dice. * Each King is randomly placed on its first two ranks. * Each Pawn is randomly placed on its second or third rank. * One Bishop is randomly placed on a dark square on the first three ranks * One Bishop is randomly placed on a light square on the first three ranks * One Rook and one Knight are randomly placed on the left half and the right half on the first three ranks. * Every remaining piece is randomly placed on the first three ranks.
