Fog of War

You see only your army and the squares it can reach, and kings are captured without check.

You see your own pieces and every square one of them could move to, including an enemy piece you can capture. Everything else stays hidden, while spectators see the full position. There is no check or checkmate: moving into attack is legal, no check warning is given, and capturing the enemy king wins. En passant remains visible for the one turn when it is available.
