Introduction

CHESSAGON® is a strategy game for two players. The game consists of a hexagon shaped board with 96 triangular spaces and 48 playing pieces. There are seven types of pieces: King, Queen, Duke, Bishop, Knight, Rook and Pawn. The object of the game is to maneuver the pieces in such a way that the opponent’s King becomes trapped and cannot escape. This is called checkmate.

Intent

The principal difference between Chess and Chessagon is that you are playing on triangles instead of squares. Chessagon was intended to be as close to standard Chess as possible except for those changes necessary to implement Chess on a board of triangles instead of squares. To illustrate, consider the following points:

The Chessagon board orientation of playing corner to corner, rather than side-to-side, on a hexagonal board of triangles is also unique feature. Playing from opposing corners allows the game to be closely analogous to standard chess. It also helps the Pawns have fundamentally similar moves and captures on triangles as compared to squares.

An addition to Chess that Chessagon makes, is for the piece called the Duke. It was logical and necessary to create the Duke to account for the expansion of fundamental board geometry. The geometry of the board demanded and dictated the need for the piece to be created to account for the increased axes of movement on the board. A Duke is analogous to a Rook. It can reach any space on the board, but its movement is rotated 30 degrees from that of a Rook. Its power level is less than that of a Rook, but slightly superior to a Knight. A Duke's movement allows it to "squeeze" between adjacent pieces as it moves across the board.

History

CHESSAGON® was created in the summer of 1977 by two brothers, Kerry Langford and Eric Langford, as a remedy for boredom and as an attempt to create a strategy game more intricate than traditional Chess, yet tactically just like Chess. The board size, orientation, and the invention of the Duke piece were all settled during that initial summer of 1977. A lot play testing was done to try alternative piece setups, variations on Pawn opening moves, and the number of Pawns in the front ranks in subsequent years. Rules for En Passant and Castling were the last items to be completed. Kerry's wife, Debra Langford, helped revise and grammar check various forms of the rule books over the years to share with family members. Eric Langford has done much proof reading and editing of the rules over the entire span of 40+ years. Kerry's son, Preston Langford, is credited with creating the first computer version of the CHESSAGON® game with a playable Artificial Intelligence opponent. Preston Langford also made the game with an online mode for playing and sharing games with other players remotely over the internet on Apple iOS devices (iPod, iPhone, and iPad) during 2017 and 2018. An update to the app was published in 2020.
