That part of my engine is very old (something like four or five years, I guess),
and I no longer clearly remember.  It is likely, however, that my book code
most closely resemble the code in Phalanx, because that was the open-source
engine which I was most familiar with at the time.

There are also a few other "Phalanxisms" in my code.  For instance, I use
exactly the same kind of piece lists (except that in Gothmog, the board
and the piece lists are stuffed into a single struct).
