Subject: BFF Rating List: 2 Thoughts

Take a look at the end-of-year Best-for-Fritz rating list, for engines running
in the Fritz GUI, at
http://www.beepworld.de/members39/computerschach2/bff-liste.htm

I have two "doubts" about the list:

1) At the bottom of the list is the Chessbase native engine Turing, with a
rating of 1572. This seems horribly inflated to me. My own "official" rating,
based on my league games, is 1430. I played a series of games against Turing and
won 8-0, no draws. My personal estimate for Turing is between 1000 and 1200. If
you can't trust the Elo values at the bottom of the list, how can you trust the
values at the top of the list? Maybe the arbitrary start value of 2600 was too
high. If a start value of 2400, or even 2200, had been used, a more meaningful
rating list would have been achieved.

2) In 21st place there is a native Chessbase engine called List 5.12. This is
neither a commercial engine, nor a free engine, so is it a secret engine that
somebody has slipped to CSS "under the hand"? Is it the engine that was
disqualified at the recent computer chess tournament in Graz? Based on the
replies to my previous question in this forum, nobody knows where it's come
from, so it doesn't deserve to be included in the rating list.
