  • Patent number: 6170826
    Abstract: A novel three person chess apparatus and method of play is disclosed. A generally hexagonal board is provided having alternating side lengths of 8 and 9 spaces. Each of the three sides in the game set up the rear rank of their pieces on one of the 9 spaced sides. A new piece, referred to in the preferred embodiment as the “Champion”, is located centrally on the rear rank, between the King and the Queen, and combines the moves of either the Bishop or Knight. The rest of the major pieces are placed in the customary positions. 10 pawns are placed in the rank immediately in front of these major pieces and play alternates in a sequential fashion between the three players until two of the Kings are checkmated or a stalemate occurs.
