About Chess960 (Fischer Random Chess)
Chess960, invented by Bobby Fischer in 1996, randomizes the starting position of pieces on the back rank while maintaining these constraints:
- Bishops must be placed on opposite-colored squares
- The King must be placed between the two Rooks
- Pawns start on the second rank as in standard chess
- Castling moves the King to c/g file and Rook to d/f file regardless of starting position
This creates exactly 960 possible starting positions (hence the name), eliminating opening theory advantages and emphasizing creativity and skill from the very first move.
