Both programs are identical, but the first one is using Fritz7.ctg (pro book)
and the second one is using Shredder6.ctg (random book).

I played 3'+2" on an Athlon XP 1800, 128M hash per engine.

The difference is on the order of 20 points, so certainly nothing significant
(may just be random noise, even).

My impression was that the one using Fritz7.ctg came out of the opening better
(with white) or equal (with black), but the engines made enough mistakes that
this was 'washed out' most of the time.

I will run another test tonight but this time using Fritz 7. It would be best to
also run a test at SSDF timecontrols IMHO, but I cannot miss my computer for
that long. Any volunteers?
