chess board International

The Chess Board of 64 squares has the following modifications:

All the Black squares are raised about 3-4 mm above the white squares.
By feeling the squares, the player is able to determine whether the
square is a black and white one.

· Each of the squares on the Board has a hole in the center so that
the pieces can be fixed in these holes.

· Each of the pieces has a downward projection (nail) at the base,
which fits into the hole in the squares on the Board, thereby fixing
the piece securely on the board.

· All the Black pieces have a dot on their heads helping the player
distinguish between a white and a black piece.

The players therefore, by feeling the raised or the lowered squares
can figure out whether the piece is on a black or a white square. By
feeling the shape of the piece, they can determine whether the piece
is a Pawn, Rook, Bishop, Knight, Queen or King. The touch of the dot
on the pieces helps the player from distinguishing a white piece from
a black one. The player is therefore able to have a clear picture in
his mind of the position on the Board. He is now ready to take on any
opponent, sighted or otherwise.
