This was about recursive reductions as FHR. What happens is at a ply you decide
to reduce depth, but 2 ply later, the conditions are still met and you reduce
another ply etc.

I dumped them because they cost to much tactical strenght. Ed's nonrecursive way
seem to give me a 5% node reduction. Not bad for 2 minutes work.
