In part 2 of the 1989 Dr Who serial The Curse of Fenric, at around the 14:40 mark. Commander Millington orders that all chess sets on the base are to be burnt.
Commander Millington also later wires a chessboard to explode.
The order to burn the chess sets is before the new inscription is translated, and Fenric is released.
While the exploding chessboard is after.
While Millington has a knowledge of Nordic mythology, he is not possessed by Fenric, and does not directly mention the specific purpose of the chess sets as a representation of the battle between the Doctor and Fenric.
Is any reason provided, either in or out of universe, on why Millington, specifically, wants the chess sets destroyed?
