Re: Lomonosov - what is the mate-distance...
Online Syzygy is a mess. It's crap.
Not the shortest way to mate.
In your pgn 11.Nb1? is -8# (11...g3 8#), best is 11.Kb2 -12# (6 men Nalimov),
your 12.Nd2 (-6#) lost another move, best: 12.Kb2 -7# (12...g2 7#)
13.Nb1? best is 13.Kb1
After 13.Nb1 is g1Q mate in 4, not your 13...h4 (mate in 7)
In your pgn after 15.Nb1 is h2 wrong, best g1Q+
After your h2 is 16.Nc3 best, not your Nd2
18.Nb1 wrong, best is 18.Kb2 Qc1+ 19.Ka2 Qxd2#
Therfore i asket to Lomonosov.

btw. 7...h5 is mate in 28 according to Houdini 6
so the syzygy line 16.Nb1 Qxb1# is a crap.
