Point Reflection: When two pieces of any colour stand on squares that are symmetric with respect to the central point of the chessboard (eg. a1-h8, b3-g6), they exchange their powers of movement. A Pawn (or a Pawn-reflected piece) on the first rank cannot move by itself. Only non-reflected K and R can castle, and only non-reflected Pawns can capture en passant.
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.
