Abstract
Abstract An improved chess set, for play by opposing two-man teams, comprises a game board fifteen squares wide and twelve squares deep. Each team has a playing piece set comprising a common king and a player set for each of the team players. Each player set, color coded for identification, comprises two rooks, two knights, two bishops and a queen disposed on the outside rows of the game board. Each player set further comprises seven pawns, disposed on the squares immediately in front of the seven principal pieces. Each team set of playing pieces further includes a warder, for common play by either team member. The warder is initially disposed on the square in advance of the king and may be moved to any of the squares within a designated "castle area". The warder may be captured only by a knight or pawn. Each team member is limited to moving the pieces of his assigned player set, plus his team's king and warder. Excepting the provisions relating to the warder, the movement of playing pieces and their capture may be the same as in the well recognized rules of the game of chess.
