Chess Variants/Balbo's Game

thumb|310x310px|Initial starting position for Balbo's Game. Introduction Balbo's Game uses a special cross-shaped board made up of 70 squares, and each player commands a full chess army minus one pawn. History Balbo's Game was created by its namesake, Monsieur G. Balbo, in 1974. It subsequently appeared in a French chess magazine, Le Courrier des Echecs, in September of that year. Rules All of the standard rules of chess apply. However, because the king starts on a different rank from the rooks, this variant has no castling. In addition, the promotion rules have been altered to accommodate the new geometry: A pawn that reaches the square at the far ends of the d- through h-files may promote to a queen, rook, bishop or knight as normal. A pawn that reaches the square at the far ends of the c- or i-files may only promote to a bishop or a knight. A pawn that reaches the square at the far ends of the a-, b-, j- or k-files may not promote at all. It will simply sit there as an obstacle until it is captured or it manages to make a capture that takes it off those files, at which point it may promote. Sub-variants This chess variant does not have any notable sub-variants. Board games Games
