It didn't have a book.  It didn't ponder.  It was run behind a web server and
played multiple games simultaneously.  It was "stateless" and without game
history had no idea of repetitions or anything to do with "game history".  It
was greatly handicapped, using exactly one DB chess processor.  Searching for a
very limited time to provide reasonable web response.

Hsu reported all of that in the past.  Is your memory that short?  Or do you
simply like to make things up.

Never mind.  "asked and answered"...
