Things to avoid?

Mention Lucena to a chess player and it will probably
conjure up images of a certain rook ending. Yet it is
also the name of a town known in Moorish Spain for its
medical expertise; in particular, any male whose
chosen profession, voluntary or otherwise, involved
singing at the upper end of the vocal range would likely
have passed under its surgeons' knives.
Thus it doesn't matter whether I am attacking or
defending in a rook ending, it is always my opponent who
is hazarding the Lucena position.
