+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.

+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?)
+
+Koth : king of the hill, king cannot move into check, giving check is forbidden (no checkmate).
+
+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)
+
+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)

+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.
