"Capture" Chess (idea of opperwezen, maybe not new): captures are forced,
but the goal is still to checkmate (not lose all material).

Cannibal Chess with forced captures.

Knightrelay: implement "official" version as Knightrelay v1

Antiking: implement v1 (deterministic) https://www.chessvariants.com/diffobjective.dir/anti-king-chess.html

Generator vatiant, called "Matrix" ?
Peces on first rank never move but generate new pieces. Pawn don't generate.
A generator captured and replaced by a similar piece does not generate.
King does not generate. No castling. En passant possible?
Goal is still checkmate.

Take(a)n(d)make : if capture a piece, take its power for the last of the turn and make a move like it.
If a pawn taken: direction of the capturer.

+ Maxima, Interweave, Roccoco, Dynamo, Synchrone
Synchrone Chess: allow to anticipate en-passant capture as well :)

S-chess https://en.wikipedia.org/wiki/Seirawan_chess

"Ball" Chess: 9x9 board, ball on center square. 2 queens ?
To take the ball when it's free you need to capture it.
To take the ball when it's used, u need to take the piece.
Goal: bring ball to final rank.
Possibles passes : soit à une pièce, soit sur une case.
  --> remplace un déplacement de pièce. Par exemple pion a2 passe à cavalier a4 = 1 coup.
  --> selon le mode de déplacement standard (donc tout droit pour les pions)
Pas de notion d'échec ou de mat (?)
Si une pièce est mat elle donne le ballon (?)
