Task: Question Generation
Input (English): In friendly games, the checking player customarily says ``check'' when making a checking move. Announcing ``check'' is not required under the rules of chess and it is usually not done in formal games. Until the early 20th century a player was expected to announce ``check'', and some sources of rules even required it (Hooper & Whyld 1992:74).
Output (English): do you need to say check in chess?
