You shouldn't worry. Crafty and Hiarcs only use the "swindle mode" if they are
already inside the TB, AFAIK. That is, if you have KRKNNP and Crafty/Hiarcs sees
that taking one of the knights draws, then it will play that move.
It will only enter the swindle mode if it gets a perfect score from the
tablebase at the root.
So analysis outside the TB's should return the correct value, not a swindled
one.
