I am probably not the right person to answer this question, because like
almost everybody else on this message board, my chessplaying abilities are
nowhere near those of the top chess programs.  However, my personal impression
of CSTal is that it is still not quite as strong as the top programs.  I
never play comp-comp games, so my observations are based only on my own games
against the programs.  I haven't made any detailed statistics, but I am
almost 100% sure my score against CSTal is clearly better than against the
other commercial progams (I estimate that I score around 20% against CSTal,
and less than 10% against Rebel or Hiarcs).  It should be mentioned, however,
that I only play fast games (30 minutes or less) against the programs and
that I run them on relaively slow hardware (a PPro 200MHz).  CSTal profits
more from more thinking time and faster processors than its competitors.

The style of play of CSTal, however, is much more enjoyable than that of
any other program.  To me, this is much more important than playing strength.
I quit playing serious chess about eight years ago, and now I only play
occasionally for my own enjoyment.  For this, CSTal is the best choice.  If
you are a serious chess player, it might be better to buy Fritz or Rebel.
For those of us who just want to have fun, CSTal is a better way to spend
our money.

In the near future, I will probably switch from my current PC to a Macintosh
Powerbook.  CSTal is probably the only PC program I will miss (in fact, it
is the main reason I still have a small Windows partition on my hard disk).
