Solution


Demotion chess: Any piece (not pawn) that sets foot on the 8th rank is immediately reborn as a pawn on the 2nd rank of the same file; promoting pawns are excempted during the promotion move.

Duellist chess: Once a unit has moved, it must continue moving turn after turn, as long as it has legal moves.

ParrainCirce: When captured, a piece is reborn on the square that has the same distance and direction from the capture square as the distance and direction between the departure and arrival square of the next move. E.g. 1. d4 e5 2. dxe5 Qe7[+bPf4]
