I tried too and it was sooooooooooooooooooo different too normal castling!
Castling in 960?

panabenja: Chess960 allows each player to castle once per game, moving both the king and a rook in a single move. After castling, the rook and king's final positions are exactly the same as they would be in standard chess.

After a-side castling (also called sometimes c-castling) the king is on c-file (c1 for White and c8 for Black) and the a-side Rook is on d-file (d1 for White and d8 for Black). This castling notated as O-O-O and known as queen-side castling in orthodox chess. After h-side castling (also called sometimes g-castling) the King is on g-file and the h-side Rook is on f-file.

Obviously castling in Chess 960 must look different than normal games. What are the rules the server uses? Does the king always move 2 spaces? Does the rook always move to the opposite side of the king? What if both rooks are on the same side of the king?
Hopefully answer a question or two.
- Normal castling rules apply
- The king and rook will always be in the same spots as they are in normal chess after castling
- To castle in normal chess, move the king his 2 squares over
- In 960, move the king on top of the rook (I think)

These castling rules are a suggested change to the normal Chess960 castling rules and result in the King always moving (unlike some castling moves in Chess960, where the King does not move at all.)
