Very simple.  :)  When I _start_ the search, I probe the tables after every root
move and discover which moves are forced draws and which are forced losses (no
forced wins or we would not be doing this.).  I exclude all moves except those
that lead to draws, and search just them.  No way it can make a mistake, but it
will choose the drawing move that gives the opponent chances to blunder...
