I propose the following change of rules for a new chess variant. It is inspired by fog of war and chess 960.
Board size and pieces are as in regular chess.
1. This is a version of fog of war or dark chess. You can see only the part of the board that your pieces can "see". However, when compared to fog of war you can see past your own pieces. They do not block your view. More precisely:
A piece can see all squares directly around it and all squares it could move to as if no own pieces would be in the way. That means that a queen can see in the 8 directions until its view is blocked by an enemy piece. (The enemy piece is seen, but not beyond.) Based on this definition a knight in the center can see the 16 squares.
The king has special seeing ability. The king can see much more than other pieces. It can see everything a queen would see that is on a square a king can move to. Note that this does not imply that the king cannot move onto an attacked square. For example, if the white king is on E1, and black has a bishop on F3 and a knight on G4, the king cannot see the night, because its view is blocked by the bishop. If other pieces of white cannot see the night either, then the white king may decide to move to F2 and be captured.
Other rule differences:
2. The starting position has only the pawns for both players. Prior to the first move players place their pieces in the first (or last) rank in any order. (Unlike in chess 960, there are no restrictions whatsoever. You can even have two same colored bishops.)
3. The goal is to capture the king. No stalemate. 4. No castling. 5. No double pawn move or en passant. 6. 50 (or such) move rule still applies.
Anyone interested in cooperating with me getting this further refined and ultimately implemented?
