Over the years a number of chess variants have been proposed for boards featuring hexagonally shaped cells (commonly called hexes). The most popular of these is Hexagonal Chess which was invented in 1936 by Wladyslaw Glinski of Poland.
David Pritchard says, in the Encyclopedia of Chess Variants, that Glinski's game is played by over half-a-million people, mostly in Eastern Europe.
This is the original file from which I made a Game Crafter edition of Hex Chess, provided here so that others may adapt to other printers, such as SuperiorPOD. To use with TGC, the file had to be split in half and lightened so as not to print too darkly.
