Historical notes

In Shogi, the Japanese form of Chess, the Dragon Horse (龍馬, transliterated as ryūma) is the promoted form of the Bishop, moving like a Bishop or a Wazir.

The piece is often used in western variants, and typically portrayed, though not necessarily named, a crowned bishop. In Man and Beast 01: Constitutional Characters, Charles Gilman calls it a Primate, which he says is a synonym for archbishop. In Archcourier Chess, it is called an Archcourier, since the Courier of Courier Chess moves as a Bishop. In Sac Chess it is called a Missionary, which is a more mobile type of clergyman. Jean-Louis Cazaux also uses this name in several of his variants.

In Holywar, Fergus Duniho called this piece a Lady, in reference to Joan of Arc, the Lady of Lorraine. In the context of this game, it was a weaker version of a Queen.

Although it isn't normally a royal piece, Fergus Duniho has used a royal version of the Dragon Horse in Fusion Chess and several more games based on it, such as Bedlam and Thunder Chess. He originally used the name of Pope, though in updating Fusion Chess, he changed it to Pontiff. By either name, it is one of four possible royal pieces, which a player can form by merging his King with a Bishop.

Movement

The Dragon Horse may slide any number of spaces diagonally, or it may step one space orthogonally. Diagonal movement follows along lines of spaces connected only at their corners. Spaces are orthogonally adjacent when they share a side in common.

For a more detailed explanation of a Dragon Horse's movement on a hexagonal board, read about Hex Shogi.
