 I also found out that Shredder Paderborn the upgrade of Shredder 6.0 can find
the correct moves order. But neither Hiarcs 8 nor any version of Fritz 8 can
find this logical move. Simply what most humans do under this kind of endgame is
to visualize the position after the Queens have been trade and black king trying
to get close to the base of white pawns formation and the White King can't
proctect the base and the g pawn at the same time.
