I've always liked CSTal, even though the released version on CD has a bug, and
the Paris version is not real strong against computers. I like the way it plays,
and I've always thought that it will improve with a faster processor more than
the tactical fast searchers. I think that the entire program, plus most of its
hash-tables could fit within the 2MB L2 cache of a Xeon, and thus operate at a
450-Mhz clip in virtually all operations. I don't know if the Win95 version will
be able to do this, as there is a lot of overhead in interfacing to an API which
is poorly written for space conservation. I'd love to see a CSTBlack (which I
don't have, so I can't speak for sure, but which is supposed to be better
against computers) running on a 450 Mhz 2MB of L2 cache Xeon in a tourney
against all the best of the rest, just to see. One of these guys here is bound
to have one soon. (Tom, can you convince Bill Bader that this would be a good
way to test the new Xeons?)
