Defensive fortresses exist for any of the two minor pieces versus the queen. However, except in the case of two knights, the fortress usually cannot be reached against optimal play. (See fortress for more details about these endings.)

  • Queen versus bishop and knight: A queen normally wins against a bishop and knight, but there is one drawing fortress position forming a barrier against the enemy king's approach (Müller & Lamprecht 2001:339–41). Another position given by Ponziani in 1782 is more artificial: the queen's king is confined in a corner by the bishop and knight which are protected by their king (Hooper & Whyld 1992:46).
  • Queen versus two bishops: A queen has a theoretical forced win against two bishops in most positions, but the win may require up to seventy-one moves (a draw can be claimed after fifty moves under the rules of competition, see fifty-move rule); there is one drawing fortress position for the two bishops (Müller & Lamprecht 2001:339–41).
  • Queen versus two knights: Two knights can generally draw against a queen if the king is near its knights and they are in a reasonable position by setting up a fortress. (Müller & Lamprecht 2001:339–41).

Famous quotes containing the words queen, minor and/or pieces:

    Oh Sleep! it is a gentle thing,
    Beloved from pole to pole!
    To Mary Queen the praise be given!
    She sent the gentle sleep from Heaven,
    That slid into my soul.
    Samuel Taylor Coleridge (1772–1834)

    To minor authors is left the ornamentation of the commonplace: these do not bother about any reinventing of the world; they merely try to squeeze the best they can out of a given order of things, out of traditional patterns of fiction.
    Vladimir Nabokov (1899–1977)

    I never had the sense of myself as an accomplished artist, and I always had to work three times as hard as anyone else to make my pieces as good as they could be. I am never completely satisfied. There always seems to be something just beyond my reach.
    Toshiko Takaezu (b. 1922)
