The pieces are Red and White, and are called Black and White
in most books. In some modern publications, they are called Red and White. Sets
bought in stores may be other colors. Black and Red pieces are still called Black
(or Red) and White, so that you can read the books. The pieces are of cylindrical
shape, much wider than they are tall (see diagram). Tournament pieces are smooth,
and have no designs (crowns or concentric circles) on them. The pieces are placed
on the dark squares of the board.
