Capablanca chess

Capablanca chess is a chess variant played on a board larger than the standard eight-by-eight grid, most commonly ten squares by eight, using two additional piece types beyond the standard set: a chancellor combining the powers of a knight and a rook, and an archbishop combining the powers of a knight and a bishop, together sometimes called knighted pieces. It was devised by the Cuban world chess champion Jose Raul Capablanca, who set out the game in a Cuban publication in 1926 out of concern that orthodox chess was approaching exhaustion at the top level and needed a larger board and additional pieces to preserve its strategic depth. Capablanca chess gave its name to a wider family of more than twenty related large-board chess variants, including Gothic chess, Embassy chess and Grand chess, which vary the board size between eight and ten files and share the same chancellor and archbishop pieces.
