Rule 3 from the original post: 3) Only and all the chess pieces listed below the grid must be used for this task, in the exact quantities given. Often, some quantity will not be known in advance, but don't worry - to obey all the rest of the rules, the quantity will be forced, and the puzzle will still have a unique solution. For example, the sample puzzle must have exactly one queen and exactly one knight, and no other pieces but rooks. One cannot use pawns, bishops, kings, amazons, grasshoppers, marshalls, cardinals, dragons, cannons, or any other kind of piece. As for the rooks, I haven't given how many will be needed - could be a dozen, could be zero - but as the solution shows, four works, and its the only value that does.
The first sentence suggests that, for this puzzle, all of the piece types (knight, queen, and rook) must be used, but the last sentence suggests that zero queens or zero rooks might also be permissible.
