This adds an element of bluffing to the game as each player tries not only to figure out his opponent's goal, but also to disguise his own goal. The rules are similar to Hidden Target Chess , but in this variant, a third person acts as a referee, randomly selecting each player's target species. Neither player is given any information as to what either target species is. The referee announces when the game is over and who won. The queen can only capture pawns.
All pieces can check and checkmate, and kings still capture everything, as usual.
Except for White's first move, each player is required to follow a normal move by a second move if possible. The second piece which is moved must be different from the first, and it must move in the same direction and over the same distance. Castling is mimicked as the king's move, two squares to the right or left. Check, checkmate, and stalemate can only be given when a turn is done. You must escape from check on your first move of a turn.
