Which is to say it is not using them in a way that will affect the outcome of
the game in a meaningful way.  At the root is a very poor way of using endgame
databases. What is the point of stumbling into a position and _then_ discovering
whether it is won or lost or drawn?  Doesn't it make more sense to use the
tablebases to _choose_ when to reduce to 5 or fewer pieces? If the authors of
programs probing only at the root would watch on ICC, they'd see just how many
times this helps crafty draw a lost ending or win a drawn ending.
