Does anyone know the specific rules of castleing in Chess960. I know the software will let you do it, but I am not sure what the official guidelines are for castleing in random arrangements are.
ok, silly me, I did a little research and this is what I found in wikipedia.
Chess960 Rules for Castleing
Fischer Random Chess allows each player to castle once per game, moving both the king and a rook in a single move. However, a few reinterpretations of standard chess rules are needed for castling, because the standard rules presume initial locations of the rook and king that often do not apply in Fischer Random Chess games.
After castling, the rook and king's final positions are exactly the same as they would be in standard chess. Thus, 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. This move notated as O-O and known as king-side castling in orthodox chess. It is recommended that a player state "I am about to castle" before castling, to eliminate potential misunderstanding.
However, castling may only occur under the following conditions. The first two are identical to the standard chess castling rules. The third is an extension of the standard chess rule, which requires only that the squares between the king and castling rook must be vacant.
If the initial position happens to be the standard chess initial position, these castling rules have exactly the same effect as the standard chess castling rules. In some starting positions, some squares can stay filled during castling that would have to be vacant in standard chess. For example, after a-side castling (O-O-O), it's possible to have a, b, and/or e still filled, and after h-side castling (O-O), it's possible to have e and/or h filled. In some starting positions, the king or rook (but not both) do not move during castling.
