Fischer random chess known as Chess960, is a variation of the game of chess invented by former world chess champion Bobby Fischer. Fischer announced this new game variation on June 1996, in La Plata, Argentina. Fischer random chess employs the same board and pieces as standard chess, but the starting position of the pieces on the players' home ranks is randomized, following certain rules; the random setup makes gaining an advantage through the memorization of openings impracticable. Randomizing the main pieces had long been known as shuffle chess; the result is 960 unique possible starting positions. In 2008, FIDE added Chess960 to an appendix of the Laws of Chess; the first world championship sanctioned by FIDE, the FIDE World Fischer Random Chess Championship 2019, was held in 2019, bringing more prominence to the variant. Before the game, a starting position is randomly determined and set up, subject to certain requirements. White's pieces are placed randomly on the first rank, following two rules: The bishops must be placed on opposite-color squares.
The king must be placed on a square between the rooks. Black's pieces are placed equal-and-opposite to White's pieces. Pawns are placed on the players' second ranks as in standard chess. After setup, the game is played the same as standard chess in all respects, with the exception of castling from the different possible starting positions for king and rooks. There are: 4 possible squares for the light-squared bishop. After castling, the final positions of king and rook are the same as in standard chess, namely: After a-side castling, the king finishes on the c-file and the a-side rook finishes on the d-file; the move is notated 0-0-0 as in standard chess. After h-side castling, the king finishes on the h-side rook finishes on the f-file; the move is notated 0-0 as in standard chess. Castling prerequisites are the same as in standard chess, namely: The king and the castling rook must not have moved. No square from the king's initial square to its final square may be under attack by an enemy piece.
All the squares between the king's initial and final squares, all the squares between the castling rook's initial and final squares, must be vacant except for the king and castling rook. A recommended way to castle, always unambiguous is to first move the king outside the playing area next to its final square move the rook to its final square move the king to its final square, it may be useful for the player to state "I am about to castle" before castling. In some starting positions, squares can remain occupied during castling that would be required to be vacant under standard rules. Castling a-side could still be possible despite the home rank a-, b-, or e-file squares being occupied, for the e- and h-files for h-side castling. In other positions, it can happen that the king or rook does not move during the castling maneuver since it occupies its destination square – e.g. an h-side rook that starts on the f-file. No initial position would allow a castling where neither piece moves, as the king must start between the rooks.
Another unusual possibility is for castling to be available as the first move of the game, as happened in the 11th game of the tournament match between Hikaru Nakamura and Magnus Carlsen, Fischer Random Blitz 2018. The starting position had kings at f1/f8 and h-side rooks at g1/g8. Both players took the opportunity to castle on the first move; the study of openings in Fischer random chess is in its infancy, but fundamental opening principles still apply, including: protect the king, control the central squares, develop starting with the less valuable pieces. Unprotected pawns may need to be dealt with quickly; the majority of starting positions have unprotected pawns, some starting positions have up to two that can be attacked on the first move. The Stockfish program rates the Fischer random chess opening positions between 0.1 and 0.5 pawns advantage for White, while the mean value for the same in standard chess is 0.2. It has been argued that two games should be played from each starting position, with players alternating colors, since the advantage offered to White by some initial positions may be greater than in standard chess.
For example, in some Fischer random chess starting positions White can attack an unprotected black pawn on the first move, whereas in standard chess it takes two moves for White to attack, there are no unprotected pawns. Fischer random chess is a variant of shuffle chess, which had been
