The last time that he played against them he used only Fritz3 on p90.
Knowing that Deep thought is better than Fritz3(p90) does not mean knowing that
Deeper blue is better than Deep Fritz on good SMP machine.

I agree that Deeper blue was better than Deep thought but I do not know if it
was practically the same as being 100 times faster.
It is possible that it was practically only at the same level of being 10 times
faster than Deep thought because of bugs.

I also do not buy the claim that it has no chances because of the gap in nodes.

I am not sure if Deep Fritz with 2M nodes per second is going to lose in a match
against old programs like Fritz3 with 200M nodes per second at tournament time
control.

One reason is better search rules of Deep fritz and another reason is better
evaluation of Deep Fritz.

I believe that Deep Fritz has also better evaluation and better search rules
than Deeper blue.
