Which is the thing >the Nolot test is supposed to detect... The first 5 moves of PV are correct. The 6th ply move (3. ... g6) is supposedly refuted by 4. Kh2! I don't know that any program has ever done better than this, including DT. I don't have the DB results because those aren't public. Other programs have found this line, but I don't think that any program has proven that it wins. The original article mentioned that DT found the line after an overnight search, but there was no mention of the score returned. Mine has found this for several years, but it returns a slightly negative score. The line it currently produces is not very good. bruce
