The new pieces allow new strategies and possibilities that change the game. For example, the archbishop by itself can checkmate a lone king in the corner (when placed diagonally with one square in between).
Setup and rules
Capablanca proposed two opening setups for Capablanca chess. His final revision placed the archbishop between the and ; the chancellor between the and . The king moves three squares when
castling instead of moving two squares as in standard chess. A pawn can
promote to archbishop or chancellor in addition to the regular promotion options in standard chess.
Unlike orthodox chess, each king, instead of each queen, starts on a square of its own color (the white king on a light square; the black king on a dark square).
Capablanca also experimented with a 10×10 board size with a different initial setup and where pawns could advance up to three squares on their first move.

The new piece names ''archbishop'' (originally named chancellor) and ''chancellor'' (originally named marshall, followed by marshal) were introduced by Capablanca himself. These names are still used in most modern variants of Capablanca Chess.
Variants of Capablanca chess
Predating Capablanca chess
Capablanca was not the first person to add the archbishop and the chancellor to the normal chess set, though he is the most famous. Other attempts mostly differ only by the arrangement of pieces and the castling rules.
In 1617,
Pietro Carrera
Pietro Carrera (July 12, 1573 – September 18, 1647) was an Italian chess player, historian, priest and author.
Biography
Pietro Carrera born in Sicily, in Militello in Val di Catania ( Province of Catania), located in the Valley of Noto; he ...
published a book ''Il Gioco degli Scacchi'', which contained a description of a chess variant played on an 8×10 board. He placed new pieces between a rook and a knight. Archbishop was on the and chancellor on the . It is highly probable that his primary motivation for the design was the limitations of
opening theory in this time and he was not as concerned with avoiding structural weaknesses in the new game’s starting position created by a potential new piece standing on a given file, as with the Archbishop between the knight and the rook leaving its own pawn unprotected. Carrera used the names ''Centauro'' (centaur) instead of archbishop, and ''Campione'' (champion) instead of chancellor.
In 1874,
Henry Bird proposed a chess variant similar to Carrera's variant. The only significant difference was the opening setup. The new pieces were now between the bishops and the royal pair, the archbishop close to the king, the chancellor close to the queen. The queen's bishop's pawn is not protected in the initial setup. Bird used the names ''equerry'' instead of archbishop, and ''guard'' instead of chancellor. The theoretical benefit of this setup is that the new pieces’ pawns are thus very important to the opening theory of the game, equally to the king’s and queen's pawns. This makes the chancellor‘s pawn a pair for the queen's pawn as leading to a more strategically oriented game from the nature of the chancellor.

Several chess variants postdating Capablanca chess were designed with initial arrangements where all pawns are protected by at least one piece; these include Universal chess, Grand chess, Gothic chess, Grotesque chess, Ladorean chess, Schoolbook chess, and Univers chess which adopted the starting lineup of Universal chess and used it on a 10×8 board, and Embassy chess which uses a starting position identical to Grand Chess adapted to a 10×8 board.
Aberg's variation has the same setup as the historic ancestor Carrera's chess. Aberg followed Murray's description, which was wrong, and invented a new game by switching the archbishop and the chancellor, thus reaching exactly the setup proposed by the 17th century Italian master.
In 2004, David Paulowich proposed an arrangement that was included in ChessV as ''Capablanca Chess, Paulowich Variant''. John Kipling Lewis re-invented it independently in 2007, giving it the name of Victorian Chess.
