Yes, the fact that it's archived is annoying.  I thought it was a
neat-enough idea to be worth doing cleanly, so I had a go:


The HTML is obviously generated by a program, and one can generate lots
of variations (even ones that will loose some games) but that can't be
done in HTML -- the complete, fixed, tree of accessible positions must
be there in the page before play starts.

(I know this is an old thread now, but Real Life got in the way of
programming as it so annoyingly does sometimes.)
