An amazon is a fairy chess piece that can move like a queen or a knight. It may thus be considered the sum of all orthodox chess pieces. It cannot jump over other pieces when moving as a queen, but may do so when moving as a knight. Chess moves in this article use A as notation for the amazon. The amazon can force checkmate on an enemyking without the help of any other friendly piece.

History
The amazon 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 experimented with and used widely in the Middle Ages to replace the old slow ferz, and competed with the orthodox queen for this role; however, the normal queen eventually won out, because of the excessive power of an amazon. In Russia for a long time the queen could also move like a knight; some players disapproved of this ability to "gallop like the horse". The bookA History of Chess by H. J. R. Murray, page 384, says that a Mr. Coxe who was in Russia in 1772 saw chess played with the queen also moving like a knight. The amazon was first used in Turkish Great Chess, a large medieval variant of chess, where it was called the giraffe. It appears most famously as the maharajah in the chess variantMaharajah and the Sepoys, where it is White's royal piece and also his only piece. The result of this game is a Black win with perfect play; the complete set of orthodox chessmen can force checkmate on a lone amazon.
Value
The amazon has a very high value because it controls every square in a 5×5 square of squares centered on itself and therefore attacks everything nearby, filling a whole area with attacks once it moves into position and forces checkmate by itself. In contrast, although the gryphon from Grande Acedrex would seem to have the value of two rooks, the squares it attacks are more dispersed and it can be more easily defended against than the amazon. In the endgame of king and amazon versus king and empress, the amazon usually wins, but in a few positions the weaker side may force a draw by setting up a fortress. These fortresses force the side with the amazon to give perpetual check, as otherwise the side with the empress can force a simplification or give its own perpetual check. King and amazon versus king is a forced win for the side with the amazon; checkmate can be forced within four moves. In comparison, the queen requires 10 moves and the rook requires 16. In fact, the amazon does not even require its king's help to force checkmate, and this great power is the reason why it is not seen as often in chess variants as the princess or empress.
