♞ Kriegspiel Fog of War Chess

How to Play

• You see only your own pieces on the board. The opponent's pieces are hidden.
• When you attempt an impossible move (e.g. move a bishop like a knight), you hear "Impossible!"
• When you attempt an illegal move (blocked by an invisible piece), you hear "No."
• When a capture occurs, both players are told the square.
• When you are in check, the direction is announced: vertical, horizontal, long diagonal, short diagonal, or knight.
• Ask Pawn Captures? to learn if any of your pawns can capture — but if the answer is "Yes!", you must attempt a pawn capture next move.
• Lovenheim variant: ask Occupies? to learn if any specific square is occupied.
• Rochester variant: when you attempt a pawn capture (legal or not), the target square is announced.
