Chess piece
In chess, each player has one of two equivalent sets of pieces (each a different color) at the beginning of the game. Each set has six types of pieces, each with its own pattern of movement:
Other pieces, not used in conventional chess but used in chess variants or certain kinds of chess problems, are known as fairy pieces.
Physical chess pieces used to play a game are usually three-dimensional figurines, taller than they are wide (a set of pieces designed for a board with squares two inches wide will typically have a king around 3.75 inches tall). They are available in a variety of designs, with the most usual known as the "Staunton design", named after the 19th century English chess player, Howard Staunton, being designed by Nathaniel Cook. On computers, chess pieces are often two-dimensional symbols on a 2D board, although some programs have fancier 3D graphics engines with more traditional styles.
For games played at the top level, pieces made of wood are usual, but for lower-level games or very large tournaments, plastic sets are more normal.
Some small magnetic sets, designed to be compact, have pieces more like those used in Shogi and Xiangqi - each piece being a similar flat token, with a symbol drawn on it to show which piece it is.
