DuchessTM is a multi-player Chess variant fo two to six players.
In addition to the King, Queen, Bishop, Knight and Rook there are two combination pieces, called the Duchess (bishop + knight) and the Fortress (rook + knight), as well as the Wizard, which moves like a King and also enables pieces next to it to move `by teleportation' in a manner explained more fully below. Pawns can move forward, backwards or sideways and take on any diagonal. They promote by moving to the central "square" (which is really hexagonal).
