I think that Ernst is saying that Fritz 6 is not a root processor.  It could
have been possible to figure this out from the node rates Fritz 6 was producing
at the WCCC in Paderborn.

A root processor notices that the only two pawns are a white on pawn on a2 and a
black pawn on b5, and figures out that the move axb5 or a5 will produce a passed
pawn, and sticks a large value into a table of potential moves.

The advantage is that in order to evaluate the move a5, you just look up a
number in a table.  The disadvantage is that the black pawn might move to b4, in
which case the move a4 should also get the bonus.

I've never seen any sort of paper about this.  There aren't a lot of good papers
about anything interesting.
