A Knights Tour

Sorry for the delayed post. The last two days I have been swallowed up trying to get a head start on the letter squares. The pieces fit together in only 9-12 different ways, so the choices can be narrowed down. I don't think this is an anagram. My hunch is that I am going to have to follow moves from a particular game. Which game, you might ask. Right now there is only one known important game. Steinitz v. Bardeleben. I've tried following all moves, white only moves, black only moves, and knight only moves. There are hundreds of combinations and since there are so many missing squares, there isn't a definable way to tell if any of them are valid. Of course, some can be eliminated due to letter sequence, but others cannot. I posted some of my results to the forum for feedback. I need a rest.
