Chess960 position 788

The back rank is R B B Q K N R N. The king starts on e1, the rooks on a1 and g1, the bishops on b1 and c1, the queen on d1.

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 e1 to g1 and the rook goes from g1 to f1.

Castling long, the king goes from e1 to c1 and the rook goes from a1 to d1.

A rook sits in the corner on a1, so bringing it into the game is usually a reason to castle early.

The queen stands next to the king, so moves that open lines towards the king tend to hit the queen as well.

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