The princess is a fairy chess piece that can move like a bishop or a knight. It cannot jump over other pieces when moving as a bishop but may do so when moving as a knight. The piece has acquired many names and is frequently called archbishop, Minister, or cardinal; it may also simply be called the bishop+knight compound. Chess moves in this article use A as notation for the princess. Movement The princess can move as a bishop or a knight. History and nomenclature The princess is one of the most simply described fairy chess pieces and as such has a long history and has gone by many names. It was first used in Turkish Great Chess, a large medieval variant of chess, where it was called the vizir (not to be confused with the piece more commonly referred to as the wazir today, which is the (1,0) leaper). It was introduced in the West with Carrera's chess, a chess variant from 1617, where it was called a centaur, and has been used in many chess variants since then. The name archbishop was introduced by José Raúl Capablanca in his large variant Capablanca chess. He originally called it the chancellor, but he later changed the names, and the rook+knight compound became known as the chancellor. Both of these names refer to higher ranks than the bishop in the Roman Catholic Church, but archbishop does so more obviously to most people and thus became more popular. In fact, the name archbishop has been used for other augmented bishops as well, such as the reflecting bishop (which reflects off the sides of the board) and the bishop+wazir compound. Christian Freeling, the inventor of Grand Chess, took a similar approach to Capablanca, naming the piece the cardinal. Princess is the most widely used name among problemists. By analogy with the queen, which is a rook+bishop compound, it was decided that the three basic combinations of the three simple chess pieces (rook, knight, and bishop) should all be named after female royalty. Since the bishop+knight compound is obviously weaker than the rook+knight compound (as the bishop is weaker than the rook), the name princess was assigned to the bishop+knight compound, while the rook+knight compound was named the empress. Value The princess is worth approximately 8 pawns. Computer self-play studies show that a single pawn is enough to compensate the difference between queen and
