Chess960 position 469

The back rank is R N B B N K R Q. The king starts on f1, the rooks on a1 and g1, the bishops on c1 and d1, the queen on h1.

White has 21 legal first moves, more than the twenty of the standard array, because the knights reach a different number of squares from where they stand.

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

Castling long, the king goes from f1 to c1 and the rook goes from a1 to d1.

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

A rook sits in the corner on a1, 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 469 on Play CPU. To train tactics on positions like it, use the Chess960 puzzle trainer.
