Chess960 position 780

The back rank is Q B R K N R B N. The king starts on d1, the rooks on c1 and f1, the bishops on b1 and g1, the queen on a1.

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

Castling short, the king goes from d1 to g1 and the rook stays on f1.

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

One thing about castling here surprises people: the kingside rook already stands on f1, so castling short moves only the king.

The pawn on d2, e2 is defended only by the king, which makes it the square both sides look at first.

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