PWC: When a capture is made, the captured unit (except a King) is replaced on the square the capturing unit just leaves. A Pawn is immovable on its 1st rank.
Anti-Super Circe: On making a capture, any capturing unit (including the King) is reborn on any free field on the board (without causing a self-check or a selfmate) or can be removed from the board . Thus every move has two active parts: capturing component (capture of enemy piece) and rebirth (replacing) component. If the first or second component is not possible, the move is illegal. The captured unit disappears as in normal chess. Pawns (white, black, neutrals, half-neutrals) can be reborn on the first or eight row. When reborn on the first row (for Black) or the 8th row (for White), the promotion (as the second move’s part) is obligatory and the promoted unit is chosen by the capturing side. White reborn Pawns on 1st rank (black on 8th) have no power. Normal, orthodox rules for castling and en passant are in force with the following additional elements: castling is permitted with the reborn King or (plus) Rook, and en passant is possible in combination with the Pawn’s promotion as second component of the same capturing move.

While the play may appear repetitive at first glance, the differentiation of the echo mates – set up at diagonally-opposite corners of the board – is achieved essentially through the secondary anti-supercirce fairy effects of the ‘captures’. The mates are a departure from the classic nB-in-the-corner mate. A tanagra alright, but white has a choice of roughly 197 available moves at the start… (Authors)
