Chess960 position 480

The back rank is B B Q R N K N R. The king starts on f1, the rooks on d1 and h1, the bishops on a1 and b1, the queen on c1.

White has twenty legal first moves, the same as in ordinary chess.

Castling short, the king goes from f1 to g1 and the rook goes from h1 to f1.

Castling long, the king goes from f1 to c1 and the rook stays on d1.

One thing about castling here surprises people: the queenside rook already stands on d1, so castling long moves only the king.

The pawn on f2 is defended only by the king, which makes it the square both sides look at first.

The bishop on a1 sits on the long diagonal behind the b2 pawn. Move that pawn and the bishop looks the length of the board at g7.

A rook sits in the corner on h1, so bringing it into the game is usually a reason to castle early.

Every rule of chess applies here unchanged apart from castling, which the rules page explains in full. To play this exact arrangement against the computer, open position 480 on Play CPU. To train tactics on positions like it, use the Chess960 puzzle trainer.
