For each leaf node (I use this term, although I don't like the definition of Bob
too much ;) you could count how many q-nodes you produce, and store the
FEN-string of the position whenever you get a new max. Then look at the position
and see why qsearch behaves so strange there. (I assume there are some positions
where qsearch goes crazy because the _percentage_ is so high *shrug*)
