This is really getting tiresome. I ran a series of games between Pro Deo S&D and
Ruffian 1.05 in Arena. Pro Deo is installed as a UCI engine which shouldn't be
an issue. Arena doesn't freeze or anything so that's not the problem. The
problem is that the analysis between Pro Deo running under Arena and Fritz,
using the exact same files (personality, etc) produces different results. As a
tie-breaker, I took a look at Chess Partner 5.3 and it produced different
analysis, not to mention different depths and times. To make things even harder
to udnerstand, at least for me, when I change the hash sizes, I not only get
different times to reach a certain depth (expected), I get different main lines
adn evaluations (not expected). Note in particular the analysis at ply depth
11-13.
BTW, don't think it may be using the Rebel.eng profile instead, since I checked
by renaming the default profile and made the Rebel.eng profile identical to my
personal settings. Just in case.

Here is an example in case. BTW, I disabled all learning, and the setting is to
now clear the hashtables.
