First, 'chessbase' doesn't impress me with their honesty.  Doesn't it seem just
a bit hard to swallow that they have a 'secret' autoplayer that works but which
doesn't get released on the 'for sale' version?  why would someone go to the
trouble to write something they don't sell, and something they don't use?  I
don't buy that for a minute.

Ed has reported before that he (at one time) had 8 machines busily playing 4
simultaneous matches against other commercial competition.  Chris Whittington
said something similar although I don't remember how many machines he says he
has.

I can't speak for the others, but I have seen this 'leap-frog' for several
years.  I only offered a reasonable explanation, regardless of who says they
don't use what.  I can _guarantee_ you that no one would write auto232 code if
they didn't use it, as it is a touchy piece of software.  Shredder is apparently
doing this as Steffen wrote the windows autoplayer stuff.  Again I doubt he did
it for the heck of it...

There's plenty of autoplaying going on whether everyone is willing to 'fess up'
or not, IMHO...  Or we have some really bright programmers wasting a lot of time
writing code they aren't using.  Speaking for myself, I don't do that...
