Abstract

Abstract A method of playing chess for two, three or four persons, the game comprises a playing board having a checkerboard array of rows of squares. Four additional playing areas are contiguous with the four sides of the checkerboard and conventional chess pieces are staged in conventional layout within the additional playing areas. Each set of chess pieces including distinguishing characteristics, such as color, for differentiation. The pawns initially move forward as in conventional chess, however, to provide for additional chess strategy the pawns may change to a second direction of forward movement by capturing an opponent on the side of the second direction on any space on the game board. The pawn may then continue to move forward in this second direction, which is a 90° change in direction. Each pawn can be provided with a mechanism for indicating which direction the pawn can move and attack. The game is played conventionally except as modified as described above.
