Very impressive from Fruit! Is Fruit MR a betaversion or a special compile? In
the analysis from Pro Deo Vulcan, the reply 5..Na6 to 5.h3 only surfaces on
iteration 19. That is after a deep search of 8 hours! A branching factor of
about eight after iteration 18. Then 5.Bf4 is chosen again as the best reply but
only by a very small evaluation margin. Currently searching that move at ply 20.
Romanishin plays 5..c6 after 5.Bf4

Used version of Pro Deo settings:
Pro Deo 1.1 Vulcan {9k16h5} testversion has gone back to
[EVALUATION = NORMAL] as with [EVALUATION = SMART] I could not find any version
that found a good line quickly in Testposition 36 from Michael Gurevich. Maybe
some tactics are slower now but the main lines als appear not to vary as much.
Maybe that depends on better tuning. This time slightly higher queen values as
in some of the CM settings. I don't usually think that works but who knows.
