Given clues such as "the rook is not next to the king" and "the bishop shares no rank with the queen", place all the pieces consistently. This is a constraint-satisfaction puzzle: each clue removes possibilities, and you eliminate until one arrangement survives.

A grid of which piece can be on which square makes the deductions visible: mark a cell impossible when a clue forbids it, and mark it forced when it is the only cell left in a row or column. Apply the most restrictive clue first, because it cuts the search the most and often triggers a chain of further eliminations.
