Editing Circe chess (section)

==Example==
The position illustrated demonstrates a couple of unusual effects which can occur in Circe. It is Black to move. White is threatening checkmate with 1.Re1#. Black would not be able to defend with 1...Kxe1 after this move, because the rook is instantly reborn on a1 from where it gives check (Black's bishop does defend a1, and the black king is free to move to e2 or capture at d2, but this is of no consequence as after Kxe1 it will be ''White's'' move.). It might appear that there is nothing Black can do to prevent this threat, but in fact he has 1...Ba1{{chesspunc|!}} – if now 2.Re1+, Kxe1 is possible because the rook is not reborn because its rebirth square is occupied.
