When Castling Is Illegal
Which of these does NOT prevent you from castling?
Choose the right answer
- Your king is currently in check

Show the answer
Your rook is currently attacked
An attacked rook may still castle! But you can never castle out of, through, or into check — and both pieces must be unmoved.
