Editing Circe chess (section)

==Rules==
These are the most usual rules employed in Circe—there are numerous other forms of the game in which the rules of rebirth may vary.

* Pawns return to the start position on the same file they are captured on.
* Rooks, knights and bishops return to the starting square which is the same colour as the square they are captured on.
* Captured queens are returned to the queen's square.

For instance, a white pawn captured on b4 is reborn on b2; a black knight captured on f6 is reborn on b8; a black rook captured on the same square is reborn on h8. [[Castling]] with a reborn rook is permitted. A reborn pawn regains its initial two-step move option. A captured promoted piece is treated as a piece (not a pawn).  

If the square that the rebirth should take place on is occupied, either by a friendly or enemy piece, the captured unit is not reborn—it is instead removed from the board and takes no further part in the game (like a capture in orthodox chess).

If a pawn captures via ''[[en passant]]'', it would be immediately in front of the reborn opponent's pawn, thus preventing either pawn from moving.

[[Philip M. Cohen|Philip Cohen]] has suggested that a move that simply reverses the opponent's previous move should not be permitted. (For example, White Qd1, Black Bg4: if White plays Qxg4, the bishop is reborn on c8, and Black should not be permitted to immediately recapture Bxg4.){{sfnp|Pritchard|2007|page=56|ps=}}
