Marseillais chess Marseillais chess Marseillais chess (also called Double-Move chess) is a chess variant in which each player moves twice per turn. The rules of the game were first published in Marseillais local newspaper "Le Soleil" in 1925. The variant became quite popular in the late 1930s with such chess grandmasters as Alexander Alekhine, Richard Réti, Eugene Znosko-Borovsky, and André Chéron playing it. A player can either move one piece twice or move two different pieces on his turn. Castling is considered a single move. When a player gives check on the first move, he loses the second move of his turn.
Touch-move rule the player is about to touch a piece on the board, typically to centralise it on its square, without the intent of making a move with it. Although this French term is customary, it is not obligatory; other similar indications may be used. A player may adjust a piece in this way only when it is his turn to move. There have been occasions in chess history when a player has uttered "j’adoube" after making a losing move in order to retract it, thus attempting to avoid the touch-move rule. Such behaviour is regarded as cheating (see cheating in chess).
