try to take the king and move it where the rook is
Castling in 960

Thank you, that works.
Why isn't this easy to find in the help? (I've actually never understood why the only thing you get when you click on "Help" is a FAQ with little to no organization at all.)
When I searched for "960 castling" the page with the answer did not come up. I tried again searching for just "960" and the "How do I castle in a 960 game" came up and has the answer.
I am currently playing a game of 960 and don't understand how to castle. Please don't comment on strategy or whether or not castling is a good idea in this position as the game is ongoing.
In the final position white should be able to castle kingside. How do I input this move? Moving the king doesn't work because it is already on it's destination square. I've tried moving the rook, but that doesn't work either.
