Well, it may is more than 50 points, but I prefer to stay lower as I do not have
to see things in an optimistic way just because I am part of the Shredder team.
I also believe with more games it should decrease a little in your table...

Well, we MUST make it more stronger now...we cannot stop...

Well, 7.04 at longer time controls is stronger than 7.0

Well, I guess this time too Uri will not criticize my "rating expectations"!:-)
And other people who made "sospicious" comments too...(I am not referring to
you)

I am amaze to see how much you love computer chess!
