No.982 by Eric Huber – A play of two Nightriders forces an appearance of the wK in Republican Chess problem. (JV)

Definitions:

Phantom Chess: Any unit except a king may move either normally (from its current square) or as though from its Circe rebirth square if the latter is vacant.

Republican Chess (Type 2): There are no Kings : if the side which has played can put the opposite King on a square where it would be legally mate, then the opposite King is put on such a square. The opposite side can then put itself the other King on a square where it is mated.

Nightrider(N): (1,2) Rider. Operates along straight lines with squares lying a Knight’s move away from each other.

Thus they force the apparition of the white King on that line and that closes the line. (Author)
