Crafty has two goals working here. (1) with an outside passed pawn, it wants
to trade material. This is all about getting queens off + as much else as it
can. (2) advancing the passed pawn. It likes Rf1 until the 8 minute mark
(this takes about 4 minutes on my notebook, 1:30 on my quad xeon) where it
decides that advancing the pawn accomplishes _both_ (it sees queens coming
off).
