Chess960 changes the starting arrangement while retaining specific castling rules. Learn the official procedure instead of guessing from the starting rook’s location.
What to do
Use a verified rules example, identify the castling side and check the king’s path and required free squares. Confirm the final placement with the applicable rules reference.
A mistake to avoid
Do not assume castling always requires the same visible motion as standard chess. Some starting arrangements make the movement look unfamiliar.
A detail worth checking
Use the event’s intended Chess960 rules rather than a home approximation. Verify both legality and the physical procedure with an arbiter when competing, especially if the starting arrangement makes the move look unusual.
Try this practical check
Study several official examples with different rook positions. Explain the final king and rook squares before moving either piece.
