Queen-side castling or long castling, a move in chess consisting of moving the king two squares toward the queen-side rook on the same rank and then moving said rook to the square the king passed over. The move cannot be performed if the player is in check, if the king or the rook in question has already moved. Queen-side castling is notated O-O-O.

Get the O/_\Omug. Symbol used in internet conversations to denote a mythological being called a Unicorn (aka Uni). It is often believed that Unicorns do not exist or that the acquisition of a Unicorn is impossible, however the reality of experience has shown contrary evidence. Should one be fortunate enough to come across a Unicorn it is important proceed with extreme caution because the path to Unicorn companionship is long and difficult.
