Subject: Variability in "Fixed Depth" Search

Author: Pat King

I've implemented a pretty generic aspirated AB with check extension and
quiescent search. Of course, with the extensions come some variability in the
node count for a given fixed depth search. But I'm finding swings of a factor of
10 in nodes searched from move to move! Is this unusual? When I get my !@#^@#%$%
hash working, will the improved move ordering help this any?

All input appreciated!
