Whenever you come out of book with negative score, you risk that the game will
end in a quick repetition, if the opponent wants to. I don't think it's possible
to guarantee a positive score for all book lines.
Putting a contempt factor solves this, but Junior doesn't know the opponent in
SSDF and plays without contempt. A possible solution is to always do contempt a
few moves out of book, but that's a bit risky.
Thanks for pointing it out.
