Chess960

Also known as Fischer Random, Chess960 is a chess variant created by former World Champion Bobby Fischer. While it follows the same rules as standard chess, the initial setup is designed to reduce the reliance on opening theory by randomly shuffling the pieces on each player's back rank.

Details

Game endings

Games in Chess960 end in the traditional ways—checkmate, stalemate, or time-out.

Bishops

Bishops must still be on opposite colors in the initial Chess960 position.

King and rook placements

The king must be placed between the two rooks to allow for castling in both directions. This means that the White king can only be placed between the squares b1 and g1 or b8 and g8 for Black.

Castling

Despite the varied starting positions, the standard rules of castling still apply:

  • It must be the first move for both the king and the rook.

  • The king cannot move through or into check (this restriction does not apply to the rook).

  • No pieces can occupy the squares the king or rook move through during castling.

Regardless of the initial locations of the king and rook, after castling, the final placement for both the king and rook when castling is constant.

This means that if White wants to castle kingside, the king must land on the g1 square, and the kingside rook must land on f1. Should White want to castle queenside, the king must land on c1, and the queenside rook lands on d1. To remember this, think about classical chess castling and where the pieces land:
