No.658 by Geoff Foster – Phantom Chess where all the pieces are neutral! (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.

Circe: Captured units (not Ks) reappear on their game-array squares, of the same colour in the case of pieces, on the file of capture in the case of pawns, and on the promotion square of the file of capture in the case of fairy pieces. If the rebirth square is occupied the capture is normal.

 No.658 Geoff FosterAustraliaoriginal – 03.12.2014Dedicated to Chris Feather Solutions: (click to show/hide) neutral Kh5 pa2f7h7 h#2            2 solutions     (0+0+4n)Phantom Chess 1.nPa2-a1=nB nPh7-h8=nS 2.nBa1-f6 nPf7-f8=nQ # 1.nKh5-h6 nPf7-f8=nS 2.nPa2-a1=nQ nPh7-h8=nB # { (C+ by Popeye 4.69)} This problem was inspired by Chris Feather’s PhantomChess problems, but here all the pieces (including the king) are neutral! In PhantomChess it is possible for a neutral piece to check a neutral king without giving self-check, because the different sides have different rebirth squares. The problem features a cyclic change of promotions. (Author)

Note that 1.a1=nQ?? is an illegal selfcheck.
