Hello all,
I wrote here about my testing some of the Nolot positions with special Pro Deo
settings a couple of days back,
http://www.talkchess.com/forums/1/message.html?426623 and at the time Nolot #3
seemed not "solvable" in a short amount of time by the special tactical
settings. I almost gave up on finding a solution with Pro Deo 1.1 - tactical
settings.
It seems however that in these settings like Pro Deo 1.1 Vulcan Q1, in which,
among other things, I simply put all material values at 90% so all the
positional values are enlarged in comparison, the use I made of [My Queen = 101]
is not entirely correct. I assumed that it would put the value of the own queen
at about 91, but for that this parameter probably cannot be used in this way.
However, I finally did manage to find a setting that in spite of this faulty use
solved Nolot #3 in about 25 minutes!

All the versions with [My Queen = 101] and [Queen Value = 90] etc. also did well
in other testpositions so that actually is a tad strange, I have not tested any
of these settings with [My Queen = 101] disabled or replaced. When I disable [My
Queen = 101] in Pro deo 1.1 Vulcan Q1d6f, Nolot #3 gets solved a lot quicker,
already within 3½ minutes! This was done about 40 versions later...
I'm not very sure about the lines at 17 and 18 ply, where Black gives back a
queen directly and even adds a Knight in the 17 ply PV...
