Judge’s comment
“A “simple” fake 0-0? This is operated thanks to a fascinating clockwork mechanism and with a long walk by the black King. The star move is the unexpected 0-0-0!! with switchback by the Rook a8: on the surface, 0-0-0 is unnecessary and Rook a8 just have to wait in the corner… As finishing touches, Rook d1 contributes to the illusion of a white 0-0-0 and black Queen returns to home square”.
