Abstract

Abstract A new chess game device and method for playing, for example, modified chess for four players. The novel chess game device includes a playing board of 260 squares using a set of twenty playing pieces consisting of 10 pawns and 10 other pieces per player for two, three or four players. Each set of playing pieces is colored in a distinct, separate color so that a different color is used to identify the playing pieces of each participant. The playing board is colored in the same four colors as the playing pieces in an alternating color fashion (FIG. 1). The set of playing pieces of the novel chess game device includes all of the conventional chess pieces and two additional pieces called the Prime Minister (FIG. 2) and the Squire (FIG. 3) respectively. The Prime Minister's sphere of movement is the same as a conventional Queen except the Prime Minister may also move a single square at a right angle in either direction to its chosen course either before it starts movement on its chosen course or after it completes all movement on its chosen course (FIG. 5). The Squire' s sphere of movement is the same as a conventional Queen except it is limited to a movement of two squares in any direction that a conventional Queen can move (FIG. 7). The method of playing the new game of chess is to use normal chess rules except as modified to utilize the larger board, the extra players, and an accelerated game to permit use by four people.

Claims Analysis

Total Claims: 6
Claim 1
Independent Claim 216 words
A chess board device for chess type play among two to four players comprising: (a) a board, having (1) a square central section being sub-divided into a plurality of smaller squares and having two diagonal lines thereon further subdividing said central section into four triangular central sub-sections, and (2) four wing sections, each being a rectangular section extending from one side of said cental section, contiguous therewith and forming with said associated triangular sub-section a complete board sub-section of said board, and being likewise sub-divided into a plurality of squares the same size as said central section squares, said board having said squares alternately colored in four different colors, each board sub-section having said squares colored alternately. with but two of said four colors, opposite sub-sections having the same two colors for their squares, wherein said color scheme serves to identify and distinguish each of said squares and wherein said diagonals serve as reference indicators for perpendicular piece movement into adjacent sub-sections; and (b) a set of playing pieces for game play on said board comprising: (1) the pieces of a conventional chess set for movement according to conventional chess rules, said playing pieces to be placed on the outermost two rows of squares of at least two of said wing sections in conventional chess arrangement.
Claim 2
Dependent Claim 216 words
A chess board device for chess type play among two to four players comprising: (a) a board, having (1) a square central section being sub-divided into a plurality of smaller squares and having two diagonal lines thereon further subdividing said central section into four triangular central sub-sections, and (2) four wing sections, each being a rectangular section extending from one side of said cental section, contiguous therewith and forming with said associated triangular sub-section a complete board sub-section of said board, and being likewise sub-divided into a plurality of squares the same size as said central section squares, said board having said squares alternately colored in four different colors, each board sub-section having said squares colored alternately. with but two of said four colors, opposite sub-sections having the same two colors for their squares, wherein said color scheme serves to identify and distinguish each of said squares and wherein said diagonals serve as reference indicators for perpendicular piece movement into adjacent sub-sections; and (b) a set of playing pieces for game play on said board comprising: (1) the pieces of a conventional chess set for movement according to conventional chess rules, said playing pieces to be placed on the outermost two rows of squares of at least two of said wing sections in conventional chess arrangement.
Claim 3
Dependent Claim 115 words
The device of claim 1 further comprising: (a) a first additional major piece having allowance for movement in the manner of a conventional chess Queen with the additional capability on any given move of a single one square step perpendicular to the conventional chess Queen movement; (b) a second additional major piece with allowance for movement in the manner of a chess Queen, but limited to the traversal of two squares per move, said additional major pieces to be initially placed on the same row as the major pieces of said conventional chess set; and (c) two additional pawns to be initially placed on the same row as the pawns of said conventional chess set.
Claim 4
Dependent Claim 51 words
The device of claim 2 wherein: (a) said first additional piece is initially placed between the King and Queen of said conventional chess set, next to said King; and (b) said second additional piece is initially placed between the King and Queen of said conventional chess set, next to said Queen.
Claim 5
Dependent Claim 24 words
The device of claim 1 wherein all of a player's pieces are removed from the board when the player's King is put into check.
