Anti-Circe (Cheylan): After a capture the capturing piece (Ks included) must immediately be removed to its game array square (necessarily vacant, else the capture is illegal). Captures on the rebirth square are not allowed. Game array squares are determined as in Circe: R, B & S go to the square of the same colour as the capture; Ps stay on the file of capture; fairy pieces go to the promotion square of the file of capture.

Circe Diametral: The captured pieces reborn on a square, which is diametrically opposed to the origin field of captured piece, i.e. a point mirrored on chessboard center. For example: a possibly captured black (white) Queen doesn’t reborn on d8 (d1), but on e1 (e8) (if e1 (e8) is occupied, then the Queen vanishes entirely from the board).

Bishop-Moose: Moves like a Bishophopper (Bishophopper: Moves along Bishop-lines over another unit of either color to the square immediately beyond that unit. A capture may be made on arrival, but the hurdle is not affected.), but deflects 45° either way on passing over the hurdle. The arrival square is adjacent to the hurdle.
