Read this about five or so years ago. It was in a short story collection and unfortunately I don't remember the name or publisher. The story was titled something like, "the spelling bee" or some thing close to that if I remember it correctly.
It started out with an old man competing in a "spelling bee" against a young upstart. You think, as you read, that the spelling bee was a traditional contest, but as it turns out, the two contestants are in fact wizards, and they are flinging spells at each other.
Anyone familiar with it or know the name (or the collection it was in)?
