-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.

-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)
