Chess960 Position Generator

Chess960, also known as Fischer Random Chess, randomises the starting position of the pieces on the back rank. This generator creates any of the 960 legal positions - ensuring bishops are on opposite colours and the king is placed between the rooks. Click to generate a random position or enter a specific position number (0-959).

Professor Archer says: Bobby Fischer invented this variant because he believed opening theory had become too dominant in classical chess. Whether you agree with him or not, Chess960 is a wonderful way to test your understanding of chess principles. When your memorised openings are useless, you discover how well you truly understand piece development, center control, and king safety.
