  This format certainly provides a lot of data.  Much of this data is
unlikely to be useful for a specific program, but having all of it
means that multiple programs which use different criteria for picking
book moves could share a book db.
  I have some doubts about the usefulness of storing an expected move,
since the first move out of book is a surprise move almost by definition.
If you know what they will play, and the current position is at
all common, you should already have the counter to their next
move in book.
  Not being an SQL expert, I do have one other concern.  Can an SQL field
of type "char" store all values from 0 to 255?  That ability is needed
if you are storing a 64 bit hash into an 8 char field.
