-# Functionality:
-On Game page "mconnect" events =>
- send lastate to them (because they have the game infos) or just "your turn" - if their turn
- remember them to send next "newmove" (or just "it's your turn") later - if not their turn
- (=> listen for "mdisconnect" as well, and gameover, and newgame)
-From MyGames page: send "mconnect" to all online players (me included: potential multi-tabs)
- When quit, send mdisconnect (relayed by server if no other MyGames tab).
-
-# Misc:
-Saw once a "double challenge" bug, one anonymous and a second one logged
-Both were asked a challenge probably, and both challenges added as different ones.
-=> would probably be solved by waiting for identity before adding people to people array

-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.

+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.

+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.
