Chess960 position 586

The back rank is Q R N K B B R N. The king starts on d1, the rooks on b1 and g1, the bishops on e1 and f1, the queen on a1.

White has 19 legal first moves, fewer 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 d1 to g1 and the rook goes from g1 to f1.

Castling long, the king goes from d1 to c1 and the rook goes from b1 to d1.

The pawn on c2 is defended only by the king, which makes it the square both sides look at first.

The pawn on h2 starts with no defender at all.

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 586 on Play CPU. To train tactics on positions like it, use the Chess960 puzzle trainer.
