That makes no sense at all to me.
Currently you know how they are rated and I don't see how
a future SSDF listing Gambit 1 point up on Deep Fritz could
make for any re-evaluation of someones opinion.

You actually wrote;
"If gambittiger can top the ssdf then I may change my mind."
I questioned whether if Gambit topped the SSDF why that should
have any influence since they are already very close.

I don't even want to think about those two paragraphs.

Again that makes no sense that CB would handicap their engine while others
do not so as to make a quicker engine game.
