Chess960 position 369

The back rank is B N R B K R N Q. The king starts on e1, the rooks on c1 and f1, the bishops on a1 and d1, the queen on h1.

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

Castling short, the king goes from e1 to g1 and the rook stays on f1.

Castling long, the king goes from e1 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 a2 starts with no defender at all.

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.

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