Champion Bobby Fischer. The starting position
of the pieces on the back rank is randomized, with a few restrictions to ensure a balanced and interesting game. The idea
of Chess960 is to reduce the advantage of memorized opening theory and encourage creative and strategic play.

position is randomized. The term "Freestyle Chess" is referring to the creative and open nature of the
variant, while "Chess960" refers to the specific rules and restrictions set by Bobby Fischer. In practice, both terms
are used to describe the same variant of chess.

In Chess960, the rules for castling are the same as in standard chess. The king and rook position after castling are the same as in standard chess. Castling is only allowed
if the king and rook have not moved before, the squares between the king and rook are empty, and the king is not in check or
moving through check.
If you castle king-side (0-0), the king moves to the g-file and the rook to the f-file. If you castle queen-side, the king moves to the c-file and the rook to the d-file (0-0-0). King-side is always the side with the e-file, and queen-side is the side with the d-file.
