-"Capture" Chess (idea of opperwezen, maybe not new): captures are forced,
-but the goal is still to checkmate (not lose all material).
+Shako, also known as UniEed Chess (Jean-Louis
+Cazaux, 1990). Board 10x10; extra pieces are
+Elephant (moves one or two squares
+diagonally, may leap intervening square) and
+Cannon (as above); CC on a1/j1 and a10/j10,
+ERNBQKBNRE on ranks 2/9, 10xP on ranks
+3/8. The name means chess in Esperanto.
+(Cazaux)
-Cannibal Chess with forced captures.
+Shogi + Makruk/Thai chess --> see on Pychess
-Knightrelay: implement "official" version as Knightrelay v1
+Interesting:
+Monochrome Chess (Proprietary game,
+Looney Industries; Andrew Looney, 1996).
+Usual men and array but pieces are all of the
+same colour. A man is controlled by the player
+in whose half of the board it stands. Thus after
+e4-e5, the pawn changes sides and reverses
+direction. When you capture (by definition, in
+the opponent’s half) there can be no recapture
+as the piece has changed sides. You may not
+immediately reverse an opponent’s move. The
+king has no royal powers but can castle. The
+men are allocated points and the object is to
+have the most points (in pieces captured) when
+the game ends, which is usually when the
+players agree or when one half of the board is
+empty. Values: King=10, Queen=8, Rook=5,
+Bishop=4, Knight=3, Pawn=1. A related game
+Martian Chess is described in chapter 38.

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

-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.
+Diamond Chess [Rynd] (J. A.
+Porterfield Rynd, 1886) --> Berolina2 ?
+https://www.chessvariants.com/rules/diamond-chess
-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.
+Bicolour Chess (Gabriel Authier, 1958). v1 et v2 : (Roméo Bédoni, 1958)
+Kings are subject to check and checkmate by
+own as well as opponent’s pieces. The Q and
+QN are interchanged in the array
+.
+v2: y but a player may capture his
+own men (TODO: only v2?)
-+ Maxima, Interweave, Roccoco, Dynamo, Synchrone
-Synchrone Chess: allow to anticipate en-passant capture as well :)
+Koth : king of the hill, king cannot move into check, giving check is forbidden (no checkmate).
-S-chess https://en.wikipedia.org/wiki/Seirawan_chess
+Berolina Grid Chess, also known as
+Gridolina (originator not noted). A
+combination of Berolina and Grid Chess.
+Better than Grid Chess since Berolina pawns
+cross grid lines more easily. Described in
+World Game Review 10 as the most popular of
+the NOST combination games. (Nost-algia
+150, also Nost-algia 112 ‘not seen’)
+--> pourquoi pas, mais faudra pouvoir tracer des lignes sur plateau (Ball, Koth, Sittuyin, celle-là, Rococo)
-"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 (?)
+Contact (quoted by David Silverman, 1971).
+White puts a knight on any square of an empty
+chessboard. Black moves the knight and
+places a marker on the square vacated. Play
+alternates. The knight may only be moved to
+vacant squares. The object is to make the last
+move. The game can also be played with any
+of the other pieces. (Your Move)

+Le gagnant est le premier joueur à marquer un but, càd celui qui arrive à installer une de ses pièces dans les cages adverses: d8,e8 pour les blancs et d1,e1 pour les noirs.

+Philippe Rouzaud, Phénix 151-152, mai 2006): Un camp peut, à la place d'un coup orthodoxe, capturer une de ses pièces et replacer la pièce capturée immédiatement sur l'échiquier. Un roi peut rester en échec durant cette action. Une pièce déplacée sur l'échiquier peut mater. Un pion ne peut pas être déplacé en première ou dernière rangée. Un roi peut déplacer et être déplacé, y compris pour se soustraire à un échec. Le roque ne peut se faire que de manière orthodoxe.
+Rouzaud-Banaddou: 1.Fxb2 (=f5) Dxc7 (=e6) 2.fxe6 dxe6 3.Txb1 (=b5) Dxe7 (=c7) 4.Txb2 (=a3) Dxf7 (=d6) 5.Txg1 (=g5) Dxg7 (=f6) 6.Txf1 (=f7)+ Rxf8 (=h4) 7.Fxb2 (=e8) Rxg7 (=c5) 8.Rxd1 (=f8)+ Rxh8 (=g7) 9.Dxg8+ Txg8 10.Txg8#

+Madrasi Chess, Abdul J. Karwathar, 1979): Deux pièces de même nature (excepté les rois) qui s'observent, se paralysent mutuellement en perdant tout pouvoir (déplacement, prise, donner échec ou mat) sauf celui de paralyser une autre pièce.
+1.e4 e5 2.Cf3 Cc6 3.Fc4 Fc5 4.Cxe5 d6 5.d4 (5.Fxf7+ Rxf7 est légal; ou 5.Dh5 Fe6 immobilisant le Fc4) 5...Fxd4 6.Dxd4 dxe5 et la Dame blanche est perdue.
