A shuffled back rank to counter strong opening knowledge. Aka Fischer Random Chess.

Introduction

Chess 960 derives its name from the 960 possible unqiue starting positions. The the home ranks are randomized, within some limitations, which makes it distinct from standard shuffle chess.

Invented by world chess champion Bobby Fischer in effort to improve the game by breaking the dependency of experienced players on opening theory.

In his own words - Bobby Fischer announces Fischer Random / Chess960

Starting Position

Pawns are placed normal, but the home rank is set up in 1 of 960 possible variations within the following rules.

  • The King must start between the Rooks
  • Bishops must remain on opposite color squares, as with classic Chess.
  • White and black home ranks pieces are set up identically, including the King and Queen facing each other on the same file.

    Castling

    The randomised home rank necessitates change in the standard castling rules. All remain the same as Standard Chess, with the exception of the starting positions and squares travelled during the castling move.

    Rather than moving two squares along the home rank, the King must move to either side of the Rook regardless of how many squares are vacant between them.

    When the King and Rook are adjacent to each other the King must be placed onto the Rook to initiate the castling.

    In this instance, the King must be placed on the same square (C8) for A Side castling, or on to the Rook for H Side castling.
