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?

        a   b   c   d   e   f   g   h

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

(In reply to Kings Problem ! by Syzygy)

my mistake...

interchange the g6 with h6... new combinations :

g8 b b b b w w w w
h6 w w w w b b b b
h8 w b w b w b w b
g6 w b b w w b b w

This is because both the kings cannot be the same colour !!!
