not at all... crafty probes deep in the search, and can buzz a hard
drive
in positions where there are 12 or fewer pieces, as it finds lots of
ways
to trade down to 3-4-5 piece endings and probe the databases.  It slows
down, but it plays *way* smarter.  I can't count the times it has won a
drawn ending, and drawn a lost one because of this... :)
