Castling is indicated by the special notations 0-0 for kingside castling and 0-0-0 for queenside castling.
If one player castles kingside and the other queenside, it is called opposite (or opposite-side) castling.
In queenside castling, the king is placed closer to the center and the pawn on the a- file is undefended; the king is thus often moved to the b-file to defend the a-pawn and to move the king away from the center of the board.
In addition, queenside castling requires moving the queen; therefore, it may take slightly longer to achieve than kingside castling.
It is common for both players to castle kingside, and rare for both players to castle queenside.
On the other hand, queenside castling places the rook more efficiently – on the central d-file.
