International Draughts

International draughts (also called Polish draughts or international checkers) is a strategy board game for two players, one of the variants of draughts. It is played on a 10×10 board with alternatingly dark and light squares, of which only the 50 dark squares are used. The two players are at opposite sides, with 20 pieces each, light for one player and dark for the other. In conventional diagrams the board is displayed with the light pieces at the bottom and dark at the top and in this orientation the lower-left corner square must be dark.

The World Draughts Federation maintains a ranking. As of October 2009 the men's list is headed by Ton Sijbrands from the Netherlands, followed by Alexander Georgiev from Russia and Alexander Schwarzman from Russia, while at the women's site Darya Tkachenko from the Ukraine is in the lead, closely followed by Tatjana Chub from the Netherlands and Zoja Golubeva from Latvia.
