Abstract: A pocket-size chess set is disclosed, comprising a pair of identical panels pivotally secured at their inner edges to a narrow third intermediate panel, whereby the first two panels may be folded together to form a case with the third panel acting as a spine. Two slidable para-magnetic checkerboard halves are provided, on the top surface of each of the first two panels. Thirty-two chessmen are also provided. Each of the latter is provided with a magnetic element on its back and bottom surfaces. Thus, each chessman may be placed either horizontally or vertically on the checkerboard halves. The squares of the latter have a recessed portion and their margins are also recessed for the placing of captured chessmen thereon. The case is kept in closed position by the magnetic attraction of the chessmen for one another.
