Since it appears that this part of Inge's patch is controversial,
I made a shortened version of it which omits the changes to
estimate_territorial_value and estimate_strategical_value,
and the function attacked_worm_value. This shortened patch
is posted as inge_1_12.2. I'm running the regressions on it now.

Do you have the results of the regressions on the version in CVS?
As I posted earlier, I only have these with the dfa enabled.
