Talk of an extra bound by someone like Ed Schroder is not something to pass over
lightly!

Any clues as to what this extra bound is?  If you want to find a best move from
every ply then the only thing I can think of is to count the number of nodes
required to refute each move.  The move that has the highest refutation count
can be assumed to be reasonable, if not the best.  I believe Bob uses something
similar to re-order at the the root after an iteration.

Am I close?
