CSTal is a great program, in the sense that it is a different program.  It plays
exciting chess and is a lot of fun for me.  I get to beat it more often than
other software but it is also more fun as it plays for a win with an almost
"human" wish to attack. Against humans, I would guesstimate its strength to be
about 2400 ELO.

However, when compared with other programs, in this case Shredder, it stands no
chance in an extended match.  I think that, had Shredder been assigned the
superior HW in this particular case, CSTal would have been lucky to score more
than a point or two out of twenty.  Against computers, its strength could not be
more than 2350 ELO.

All this said, I have to reiterate:  I love CSTal.  It stands for that great
romantic paradigm in chess and no program is even close.  (Except for perhaps
the Super Constellation in the old days...)
