Queen (chess) to the announcement of "check". Some published rules even required this announcement before the queen could be legally captured. This custom was largely abandoned in the 19th century. 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" (knight). The book "A History of Chess" by H.J.R. Murray, page 384, says that William Coxe who was in Russia in 1772 saw chess played with the queen also moving like a knight. Such an augmented queen piece is now known as the fairy chess piece "amazon".
Fairy chess piece "pao" and "vao" (derived from the Chinese cannon) and the "mao" (derived from the horse). Those derived from the cannon are distinguished by moving as a hopper when capturing, but otherwise moving as a rider. Pieces from xiangqi are usually circular disks, labeled or engraved with a Chinese character identifying the piece. Pieces from shogi (Japanese chess) are usually wedge-shaped chips, with kanji characters identifying the piece. Fairy pieces vary in the way they move, but some may also have other special characteristics or powers. The joker (in one of its definitions) mimics the last move made by the opponent.
