No.732 by Peter Harris – Interesting miniature in a typical elegant author’s style! (JV)

Definitions:

Royal piece: Piece that executes a function of the King on the board.

Sentinels Pion Advers: When a piece (not a Pawn) moves, a Pawn of the colour of the opposite side appears on the vacated square if it is not on the first or the last rank, and if there are less than 8 Pawns of that colour on the board.

Einstein chess: All units (Ks excluded) change their type when they move, according to a precise pattern. For non-capture moves: Q>R, R>B, B>S, S>P, P remains P. For capture-moves: R>Q, B>R, S>B, P>S, Q remains Q.

This gives rise to an incorrect third h#2 solution and omits one hs#3 solution. (Author)
