Anti-Circe Anti-Circe Calvet (the default type): 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 allowed. 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.

Rather interesting annihilation strategy in all four phases (set, 2 tries and solution), with consequent use of annihilation.
Minus from the point of view of changes: the checkmate 2.Sxd2 (Sd2→g1)# is not properly transferred as it follows both 1…dxc2 (Pc2→c7) and 1…dxe2 (Pe2→e7) in both phases with keys capturing on the c-file. Although always only one of defences defends against relevant threat in respective phases, the other unfortunately besides threat allows also the mate Sxd2 (Sd2→g1)#. (For proper mates transference see e.g. this #2 by Mikhail Marandyuk: http://www.jurajlorinc.com/chess/ukrajina.htm#uloha1 )
