The game Fischer random chess, played with conventional chess pieces and rules, starts with a random selection of one of 960 positions for the pieces. Arrangements of the pieces are restricted so that the king is between the rooks and the bishops are on different colored squares. In order to both select a valid arrangement and to then concisely discuss which randomly selected arrangement a particular game used, the Fischer random chess numbering scheme is used: a number between 0 and 959 indicates a valid arrangement and given an arrangement the number can be determined.
