In 2268, the USS Enterprise used a chess-based code which mentioned the queen as a command authorization code. The sign for transporter clearance was "queen to queen's level 3," and the proper counter-sign was "queen to king's level 1." (TOS: "Whom Gods Destroy")
When the computer of the USS Enterprise-D was affected by nanites, it responded to an inquiry with "pawn to king three, knight to rook four, queen to bishop three". (TNG: "Evolution")
When Q set a challenge for the bridge crew of the USS Cerritos in 2380 by placing them on a large chess board (with elements of several other games and sports), he made Captain Carol Freeman into the queen. (LD: "Veritas")
