Hello Howard,
At move 46 (second diagram) Fritz had a score of -2.50 meaning it was losing
badly.  The score slowly dropped with each move until 50. Nd4 (+0.88).
I honestly like the way Rebel plays most of the time.  It seems like
occasionally it is completely blind to what is happening.  Examples are the mate
in 6 posted here a few days ago.  Rebel could not find it after 18 plies of
search.  I have seen Rebel lose games which should have been easily drawn.  At
the same time it sometimes beats Fritz and Junior easily.  It's too early to
tell for sure if the auto232 is hurting Rebel because I only have 44 games.  But
my feeling is that it is hurting but I can't tell to what extent yet.  I can
only say that the manual results are already taking a lead vs the auto232
results so is it a coincidence or is it already showing up?  By the way, thanks
to Mogens, I found another game which I played with Fritz not using the
"Optimized" book settings which Rebel drew as white.  I replayed the game and
Rebel won so the score against Fritz in manual games ended at 11-9 favor Fritz
6.  The auto232 games are not affected by my errors since the optimum book
setting is set automatically.  It was 14-6 favor Fritz.   Also I changed to G/30
minutes to go faster and in the first 3 games vs Junior (manual) the score is
2.5-0.5 favor Rebel.  So it's easy to understand why I feel there is a definite
cause-effect working with auto232.  I have to sit and watch all the games played
manually and can't help but see how Rebel plays.
