Abstract
Abstract A game board for use with three sets of chess pieces whereby three players may simultaneously compete, each against the others. The board is in the shape of an equilateral triangle within which are three play areas each containing 36 rhomboid-shaped play spaces. At the center of the board is a space as an equilateral triangle connecting the three play areas. Between pairs of play areas is an area of elongated paths linking adjacent play spaces of each pair of play areas. A parallelogram-shaped area in each corner of the board provides a buffer between players.
