Abstract: A chess set construction permitting chess to be played with the chess board in a vertical position, removably mounted in a frame on a wall, and in a horizontal position, as on a table. Each chess piece is bisected, being rejoinable by a tongue and groove. At least one of the halves of each chess-piece has a magnet, and the chess board is a magnetic receptor, such that each such magnet half piece may be held in playing position on the chess board when the chess board is vertical on a wall, with each half piece being viewed in normal upright profile. Display storage provisions are made for the halves of each playing piece not in play. The chess board is removable from the wall frame with the half-pieces remaining in position for continuation of play on a horizontal table.
