A friend told me about a chess game he had seen. At certain moment, the only pieces on board were a Queen at h8, a Rook at g6, and the Kings at h6 and g8. He didn't remember what color was each piece, but it can be worked out... how?

If the Rook had been at g7, what would have been the colors?

(In reply to Solutions by e.g.)

In the second scenario, how did the white rook get from g7 to g6 at the same time as the white pawn was advancing from h7 to h8?
