Hi Kurt,

comparing different ELO lists available I observed the following, when I compare
Fritz and Junior and this seems to be valid for different Fritz versions:

Blitz: Fritz mostly ahead of Junior
Active (Rapid) Chess: more or less at the same level
Tournament time control: Junior mainly better than Fritz (hard to find a lot of
tournaments here, so I refer to SSDF and your tournaments especially)

So my conclusion would be that Junior gains strength above average the more time
is given to the engine and engines like for example Fritz do not. Hiarcs for
example also is a very good blitz engine, but seems to have worse results
(disproportionate) with more time (SSDF).

Hard to say what could be the reasons for this phenomenon.

Opposite to you I am interested in all time controls, thinking on the other hand
that tournament chess is the "king´s category".

So let us hope that there will always be tournaments with long time control, no
matter how fast computers will be in the future.

Best Regards
Heinz
