Abstract
Abstract A chess-like board game apparatus for three player chess is disclosed. The apparatus consists of a game board of such architecture so as to present to each of three players a portion of the overall board, which three portions consist of forty-eight playing positions each, arranged in eight file rows and six rank rows. The head of each of these segments is aligned with the external sides of an equal-sided triangular shaped board segment consisting of twenty-four positions. The game is played by three opponents, each employing a full complement of traditional chess pieces whose movements, although similar to what they would be in the conventional game of chess, are further governed by a set rules specific to the game apparatus.
