How Marseillais chess is played
Marseillais chess is chess with two moves a turn. Everything else is as in chess: the board, the men and their moves, castling, promotion and checkmate.
The turn
Each player makes two moves in a row, with the same piece or with two different ones. White begins with a single move (the Balanced game); after that every turn has two. Your king may never be left in check, not even after the first move of your turn, so a king cannot step into check and out again.
Check
A check given with the first move ends the turn at once: the second move is lost. A player in check must escape it with the first move of the turn, and may then make the second.
En passant
A pawn that made a double step with either move of the opponent’s turn may be taken en passant, but only at once, with the first move of your turn. If the opponent made two double steps, you may take both pawns: the second with your second move, right after the first en passant capture.
Castling
Castling is one move, under chess’ conditions. A king or a rook that moved earlier in the same turn has lost the right.
Mate and stalemate
A player in check who has no legal first move is mated. A player who cannot make both moves of the turn is stalemated, a draw, unless a check with the first move ended the turn: so a king that can step out of check but then has no second move is stalemated, not mated.
Draws
The sources name no other draw, so the app draws when the same position stands at the start of a turn of the same player for the third time, after fifty turns by each player without a capture or a pawn move, and when neither side can mate: king against king, or king and one knight or bishop against king.
Balanced and Classical
In the original game of the 1920s, the Classical start, White’s first turn had two moves too. Robert Bruce gave White a single first move to balance the game, and this Balanced game has replaced the original among expert players. You can choose the Classical start when you set up a game.
Other readings
The app plays the rules most sources give. In the early years a check with the first move was sometimes illegal instead. Pritchard’s Popular Chess Variants (2000) allows en passant only against a double step made with the opponent’s second move, and some programs allow one en passant capture per turn.
The story
Marseille, France · published 1925
When and where
Marseillais chess was first published in 1925 in Le Soleil, a newspaper of Marseille. It is commonly credited to Albert Fortis, a journalist of the city, with the Norwegian I. Rossow, around 1922; a German magazine of 1926 gave a better claim to Jehan de Queylar, said to have set down the rules during the First World War. The credit for making it popular belongs to Fortis.
How it changed
Everything is chess but the turn: each player makes two moves in a row, with one piece or with two. A check given with the first move ends the turn, and a player in check must escape it with the first move. Robert Bruce balanced the game by giving White a single move in the first turn, in the 1950s by Pritchard’s account, in 1963 by others; Alessandro Castelli held that the original game was a win for White.
Today
It was in fashion in Paris in the late 1920s, with tournaments in Paris in 1926 and Hamburg in 1927, and Alekhine, Réti, Znosko-Borovsky and Chéron among its players. Boyer and Klüver revived it in the 1950s, E. T. O. Slater ran events by post, and from the late 1970s the Italian association AISE played it; Castelli wrote its theory in Scacchi Marsigliesi (1996). The balanced game, adopted by the American NOST and by AISE in 1990, has replaced the original among expert players, though Fabrice Liardet still holds tournaments of the original in Geneva.
Did you know?
In Mme Alekhine’s salon Mme Léon-Martin beat Réti and lost only narrowly to Alekhine himself. A game Fortis–Alekhine of 1925 survives, and the magazine Chess reinvented the game in 1939 as “SuperCharged Chess”.
