Lumberjack Bruce Zimov wrote me about a chess variant, he invented in 1973. The game was played with much enthousiasm in Cincinnatti in a period where many chess variants were tried out there. Rules All pieces except pawns move according to the column they are on - following the movement of the type of piece that starts the game at that column in usual chess. So, for instance, a king on a4 moves as a rook, but still may not move to a square that is attacked by an opponents piece.
Pawns move as in usual chess.
Bruce Zimov wrote that the game becomes interesting when combined with another variant, like Alice . Written by Hans Bodlaender, based on an email of Bruce Zimov.
