Uh huh :) Lots of debugging time before you! ;)

I think this article was discussed in ICC already, maybe 1-2 years ago. Wasn't
it a 14 year old who wrote it? I think the general opinion was, that while the
ideas the guys mentions maybe have some potential, he also missed to cover a lot
of issues which rotated bitboard solve cover. I think Bob's reaction was mainly
'let's wait and see...'.

Given the fact that there's no Hyperbola-chess-engine in sight after 2 years and
the fact that the original page doesn't exist anymore, it seems to me that the
writer found a real life (as opposed to whoever reads/writes this *smiles*) and
stopped working on chess engines. :)

HTH (ok, prolly it doesn't...)
