Andreas If you "know" the other two; the three shared segments all overlap at least 7cM; and no pair are close relatives; I don't why it wouldn't be triangulation. 100% is hard to certify when using DNA; but the odds would be very high. So if the other person is Anon, I still don't see much value, other than stabilizing a TG.
