Abstract

An improvement for a chess set comprising an eight-row by eight-column pattern of sixty four playing squares on a playing surface of a chess game playing board and two sets of visually distinct playing pieces each having eight pawns, two knights, two bishops, two rooks/castles, one queen and one king. A first set of one or more magnets having a North pole and a South pole is arranged in the board underlying the light squares such that the North pole is oriented toward the playing surface. A second set of one or more magnets having a North pole and a South pole is arranged in the board underlying the dark squares such that the South pole is oriented toward the playing surface. A first one of the bishops of each set movable only on the light squares includes a magnet having a North pole and a South pole arranged in conjunction therewith such that the South pole is odented toward the playing surface whereby the first bishops attract to the light squares and are repelled from the dark squares. A second one of the bishops of each set movable only on the dark squares includes a magnet having a North pole and a South pole arranged in conjunction therewith such that the North Pole is oriented toward the playing surface whereby the second bishops attract to the dark squares and are repelled from the light squares. In one particular modified construction, the chess pieces are weighted according to the convention of comparative or exchange value: each pawn weighs one weight unit, each bishop and knight weighs three weight units, each rook weighs five weight units and each queen weighs nine weight units.

In a chess set having an eight-row by eight-column pattern of sixty four playing squares on a playing surface of a chess game playing board and two sets of visually distinct playing pieces each comprising eight pawns, two knights, two bishops, two rooks/castles, one queen and one king, the sixty four playing squares comprising thirty-two light squares and thirty-two dark squares arranged in an alternating light/dark pattern in each of said rows and each of said columns, the improvement comprising:

a first set of at least one magnet having a North pole and a South pole arranged in connection with said board and underlying said light squares such that the North pole is oriented toward the playing surface, and
a second set of at least one magnet having a North pole and a South pole arranged in connection with said board and underlying said dark squares such that the South pole is oriented toward the playing surface,
a first one of said bishops of each of said sets movable only on said light squares including a magnet having a North pole and a South pole arranged such that the South pole is oriented toward the playing surface whereby said first bishops attract to said light squares and are repelled from said dark squares, and
a second one of said bishops of each of said sets movable only on said dark squares including a magnet having a North pole and a South pole arranged such that the North pole is oriented toward the playing surface whereby said second bishops attract to said dark squares and are repelled from said light squares.
