Circe Rex Inclusive: Captured units (including 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.
Castling Chess:
1. A king is allowed to castle even if it has already moved.
2. A king is allowed to castle with any piece of either colour, standing on the same diagonal or orthogonal, under the assumption that intevening squares are empty, it is not in check and it will not cross fields attacked by the enemy.
3. For the implementation of castling the king moves two squares towards its partner, while this partner jumps over the king and lands on the next square.
Grasshopper(G): Moves along Q-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.

The following version of no.1003 has an extra “castling” with the Knight.

Circe Rex Inclusive
Castling Chess
1.Kb2 2.Ka3 3.Kc5(Se7->b4) (“castling”) 4.Kd6 5.Ke7
6.Kc5(Sb4->d6) (“castling”) 7.Kb5 8.Kd3(Kf1->c4) (“castling”)
9.Ke2 10.Kf1 11.Kd3(Kc4->e2) (“castling”) 12.Kd2
13.Ke1 Se8 #
In the following setting both “castlings” with the Knight are orthogonal, and there is also a capture of the Knight!

9.Ke2 10.Kd1 11.Kf3(Kg4->e2) (“castling”) 12.Kf2 13.Ke1 Se8 #
So.. in Casling Chess, the other piece involved can be at any distance from the King?
The following setting has 5 “castlings”, as well as a capture of the white King!
