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.
