Robert,

it's a good question. There is no "perfect" test setup.

When I want to test engine changes (which is what you are doing), I use one of
the following two setups:

1) Pre-determined positions. I have my own testsuite of 220 positions, also some
public ones like Silver, Noomen, etc are good.
2) Junior 9 book for both engine, with maximum randomization and no learning.
(Ie. in Fritz GUI, top slider all the way to the right, bottom two sliders all
the way to the left, "tournament book" unclicked). Both engines get white and
black from each position.

The main thing is to play lots of games.
