Hello Bob,
You are right as usual.  You also know more about what is happening with Crafty
than anyone else so it's hard to argue with you about Crafty.  I have seen
examples of GM's/IM's playing against Fritz/Junior on ICC(Very few).  When these
"Draw-Kings" try to take a computer into a locked up position it's hard to
prevent it.  I'm sure Crafty is better at this than the commercials since you
have spent a lot of time working on these particular problems.
I'm not sure I believe you when you say you don't care where you are relative to
the commercials. :)  I'll bet you would love to be at the top of the SSDF list!
I do believe that it is not your primary goal.  I don't think the commercials
have a goal that is too far different from yours.  Their priorities may be
different because of sales goals but I'll bet both of you would love to be at
the top of the SSDF list and also be able to beat most any GM.  The second
appears harder than the first.  I don't believe you can achieve the goal of
beating most GM's without also being in the running for the top spot on the SSDF
list (At this time anyway).  Rebel seems to be mostly in the group that is more
interested in beating GM's than topping the SSDF list also.  I'm willing to bet
that Ed would also love to be at the top of the SSDF list too if it was
possible.  You seem to be playing a "game within a game" vs the top players on
ICC.  They look for "loopholes" in Crafty and you look for ways to fix them.
For this reason, Crafty may very well be better prepared to play GM's now than
Fritz but that's hard to prove without a lot of man/machine matches.  I do know
that the few GM's I've seen play Fritz/Junior at blitz on ICC didn't fare to
well.  I believe I did see GK destroy Hiarcs 7.32 at 2/1 on ICC but can't be
sure since he played as a guest.  But as you know GM's can prepare lines that
computers can't understand especially at 2/1 time controls so this is not as
great an accomplishment as some might think.
In my opinion, the progress you are making with Crafty is just as great as what
the commercials are doing.  It just looks to me like they had a head start in
the PC business and catching up is a difficult process.  This is especially true
since your innovations are public knowledge and the commercials are not bashfull
about grabbing your ideas.

Jim Walker
