     and a knight.


The new pieces have properties that enrich the game. For example, the archbishop by itself can checkmate a lone king (king in a corner, archbishop placed diagonally with one square in between).

Setup of the pieces

Capablanca proposed two opening setups for Capablanca Chess. In one opening setup, he proposed that the archbishop be placed between the bishop and the queen and that the chancellor be placed between the king and the king's bishop. This setup has the flaw that it leaves the pawn in front of the king's bishop undefended, allowing white to threaten mate on the first move.

He subsequently revised the opening setup so that the archbishop was between the queen's knight and bishop, and the chancellor was between the king's knight and bishop. He also experimented with 10×10 board sizes, where the pawns could move up to three squares on the initial move.

 writes (p. 39):
...I played many test games with Capablanca, and they rarely lasted more than twenty or twenty-five moves. We tried boards of 10×10 squares and 10×8 squares, and we concluded that the latter was preferable because hand-to-hand fights start earlier on it.

, thought that there were too many strong pieces, making the minor pieces less relevant.

The names for new pieces, Archbishop and Chancellor, were introduced by Capablanca himself. These names are still used in most modern variants of Capablanca Chess.

Variants that predate Capablanca Chess

Capablanca was not the first person to add the Chancellor and the Archbishop 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.

 published a book Il Gioco degli Scacchi, which contained a description of a chess variant played on 8×10 board. He placed new pieces between a rook and a knight. Chancellor was on the king's side and archbishop on the queen's side. Carrera used names champion instead of chancellor and centaur instead of archbishop. The game was largely forgotten after the death of the inventor.

In 1874, Henry Bird proposed a chess variant similar to Carrera's variant. The only significant difference was the opening setup. The chancellor was placed between the queen's bishop and queen and the archbishop was placed between the king's bishop and king. Bird used names guard instead of chancellor and equerry instead of archbishop.

), which adds the two pieces to the standard game in a different manner. The player, after moving a piece (for example, a bishop) from the first rank, may immediately place either of the two pieces on the bishop's square. If the player moves all his eight officers without placing the Hawk or the Elephant (Seirawan's names for the Archbishop and the Chancellor, respectively), he forfeits his right to do so.
