The present invention relates to a board game and more particularly to a modified chess game.
Traditional chess is a game requiring strategy. It provides the pleasure of analytical thought and has been used by schools to help develop analytical thinking. However, some players, including the great champion Capablanca, have felt a need for some modification of the conventional game of chess.
There are numerous prior art patents that disclose variations of the traditional game.
U.S. Pat. No. 4,093,237 issued to Gary Weiss in 1976 discloses a chess game that can be played by more than two players.
U.S. Pat. No. 4,553,756 issued to Robert L. Linnekin in 1983 discloses a chess game that is played with a circular board.
U.S. Pat. No. 5,125,666 issued to Timothy Adams in 1992 discloses a modified chess game that is played by four players.
U.S. Pat. No. 5,033,753 issued to Tom Yuen et al. in 1992 discloses a game similar to chess but which includes a number of pieces not found in chess. The rules for the game are quite different than those of traditional chess.
U.S. Pat. No. 5,484,157 issued to Michael King in 1994 discloses a chess game in which military pieces are substituted for the traditional chess pieces.
U.S. Pat. No. 5,662,329 issued to Richard Nason in 1997 discloses a chess game utilizing a three-dimensional game board.
U.S. Pat. Nos. 5,690,344; 5,692,754; 5,901,957 and 6,095,523 each disclose modified chess games in which pieces with powers not provided to traditional pieces are included as part of the game.
U.S. Pat. No. 5,690,334 issued Nov. 25, 1997 discloses a chess variant denoted as Falcon chess. Falcon chest includes an extra game piece called a “falcon” which can be moved in straight and diagonal movements.
U.S. Pat. No. 6,116,602 issued in September 2000 discloses a four handed chess set with a number of additional pieces but with no piece equivalent to the beast of the present invention.
The Encyclopedia of Chess Variants by D. B. Pritchard Published by Games & Puzzles Publications, P.O. Box 20, Godalming, Surrey GU8 4YP, United Kingdom. This provides information concerning other variations of traditional chess.
While numerous modifications of traditional chess have been provided, none have included the modifications provided by the present invention.
The game of the present invention is related to traditional chess but has an additional type of piece with expanded powers different than the powers of traditional chess pieces. The additional piece is labeled a ‘beast’ for purposes of the present disclosure.
Unlike Falcon chess where the piece called a “falcon” can only move straight and diagonally the “beast” of the present Chess variant, called Tensor Chess, blocks opposing pieces and shields its own like-colored pieces while allowing its own players to pass through the piece. The beast also allows its own pieces to “bounce” i.e. Shift movement in new directions. The beast can be “propelled if one of its own pieces lands on a square occupied by a beast. The beast, on the same turn, can be sent off the square, moving in the manner of the piece that landed on the square.
The pieces disclosed in U.S. Pat. No. 6,116,602 have enhanced powers but none have the powers provided to the beast of the present application.
A better understanding of the game of the present invention can be had by referring to the drawings in which:
Referring to
In the drawings the pieces are designated as follows:
While the board is shown in the drawings as having squares all of the same color, it is intended, at least in the preferred embodiment that is now being described, that a two-color chessboard be used. The board is being shown as not including colored squares to avoid confusion in describing the position and movement of the pieces of the modified chess game of the present invention.
In general the rules of traditional chess apply to the modified chess game of the present invention unless otherwise noted.
The conventional pieces are provided except that an additional type of piece, a beast W, is provided for each player, each player getting two such beast pieces. The conventional pieces, in addition to having all of the traditional powers of movement, capture and promotion, have augmented powers as will be apparent as the description proceeds.
The beast cannot capture or be captured by anything except an opposing beast. Other pieces, including another beast, are able to ‘pass through’ a beast of the same color, i.e., move along the piece's normal line of movement as if the beast were not there; but opposing pieces, other than a beast (or a knight), are unable to pass through or over a beast of another color. Thus a beast acts as a shield for pieces of its own color but allows pieces of the other color to be attacked.
The beast is able to move one square in any direction to an unoccupied adjacent square. The beast is also able to move by hopping or leaping over its own adjacent or opposing adjacent pieces either diagonally as in checkers or orthogonally (along a rank or file), but not orthogonally and diagonally on the same turn. The beast is able to make multiple leaps in a given turn and by leaping could even move forward, backward, and sideways orthogonally on the same turn or diagonally forward and backward. The beast is able to capture an opposing beast by leaping over it and landing on the square beyond if that square is unoccupied. But capturing is not obligatory when making such a leap.
As described in more detail below, a bishop, knight, rook or queen may ‘bounce’ or ricochet off one of its own beasts. This maneuver is also referred to as a ‘beast bounce’ although the other piece ricochets off a stationary beast. Kings and pawns cannot bounce. A beast may bounce off a beast of the same color if the first beast initially moves one square (no hop) to get to the square occupied by the second beast, bounces at a right angle to its prior line of movement, and ends adjacent to the second beast. There is a limit of one bounce to a turn no matter what type of piece bounces. Captures can be made at the end of a bounce except by a beast bouncing off another beast.

A queen can bounce by moving to a square occupied by a beast of the same color and then moving off at a right angle. If the queen moves to the beast along a diagonal, it can bounce only along a diagonal. If it moves to the beast square orthogonally, i.e., along a rank or file, it must bounce along a rank or file. For instance, if it came to the beast along a file, it could bounce by then turning at a right angle and moving along the rank on which the beast is situated. The queen cannot approach the beast square diagonally and then bounce orthogonally or vice versa. In understanding this restriction, it may help to remember that in orthodox chess a queen may move like a bishop or like a rook but not both ways on the same turn.
A beast may make a bounce by moving one square to a square occupied by another beast of the same color and then moving off at a right angle. It cannot hop or capture on the same turn.
A knight, bishop, rook or queen can ‘propel’ a beast of the same color. This could be considered a two part turn. First the piece moves unto the square of the beast, and then the beast moves as though it were that piece. However, a propelled beast is not allowed to capture on that turn. A propelled beast could move forward, backward, or sideways. It may, for instance, follow in reverse the trajectory of the propelling piece and land on the square originally occupied by that piece or further back.
A beast propelled by a queen would move diagonally like a bishop if the queen had come to the beast square along a diagonal like a bishop and like a rook if the queen had come along a rank or file.
A king cannot propel a beast.
A beast cannot propel another beast per se, but a beast passing through or bouncing off another beast could have a similar effect.
A pawn may propel a beast but only on the pawn's first move and only one or two squares vertically forward along the same file. The propelled beast would end up on the square just in front of the pawn. For example, if a pawn is at square A2 and a beast of the same color at square A3, the pawn could move to A3 and propel the beast to A4, or move to A4 and propel the beast to A5. If a pawn is at square A2 and a beast at A4, the pawn may move to A4 and propel the beast to A5. Neither the pawn nor the beast could move through or capture other pieces that turn.
A piece that can propel as described above, may come to the beast square by means of a bounce and then propel the beast. A bounce may proceed a propelling on the same turn. Likewise, a propelled beast may bounce in the same manner the propelling piece would bounce. But there may not be more than one bounce or one propelling on a given turn.
The capture of an enemy piece, including a pawn, ends the player's turn.
A player shall have the right to castle as in conventional chess with a castling rook ending up adjacent to the castled king, but the player has the option to place the king one, two or three squares from the side edge of the board with the rook adjacent if castling queen side and one or two squares from the side edge with the rook adjacent if castling king side. To castle, the king moves at least two squares and cannot move into a corner. The rook moves to a square adjacent to the king but closer to the center of the rank. As in conventional chess, neither the king nor the rook involved can have moved prior to castling.
Castling may be done through a beast of the same color, but this is the only time a king can pass through a beast and the beast may not move on that turn. The position of the beast may limit castling options. For instance, if the beast is at I1, the king may castle king side but only with the king ending at H1 and the rook at G1 since the beast occupies I1.
As in conventional chess, a player may not castle when the king is in check or when the king would have to pass through a square where it would be in check. But a king may pass through a square to castle if a beast of the same color occupies that square even if an opposing piece would otherwise check the king on that square. The beast occupying the square nullifies the check.
A pawn can promote to a beast when it reaches the other side of the board.
In the preferred embodiment, the board is a rectangle eight squares deep by ten squares wide. The size of the board could be varied however without departing from the invention. For instance, the board could be ten squares wide but nine or ten squares deep.
As shown in
While the additional piece W of the present application has been labeled as a “beast” it should be understood that other names such as “wizard” could be used to name the piece W without departing from the scope of the present invention. Any name could be used for the piece. What is important is that it has the powers of the piece W. The use of the term “beast” in the following claims is not intended to limit of the claims to a piece having this name.
Although several variations and modifications of the present invention have been described, it should be apparent to one skilled in the art that other modifications could be made without departing from the spirit of the invention as set forth in the following claims.
