Abstract: This invention introduces an expanded Chess Game played on 10×10=100 square chessboard. The rules of the classic game apply as directed by FIDE (rules as of Apr. 1, 2004), with adjustments made in consideration of the larger board and added pieces. The ChessQuire/Chess 100 game introduces only one new type of chess piece named here “Esquire”: white squares bound and black squares bound; four of them in total, two on each side of the board, belonging to the two opposing sets. Esquire's properties and behavior are somewhere in between that of a Knight and a Bishop. The other notable changes are the extra four pawns on the board; two on each side, and a slight pawn move rules modifications such as the en-passant rule and castling. My goal was to expand the classic game in such a way that the classic game's integrity and soul stay preserved. The game can be played at chessquire.com.
