Hello Chesscomputerfriends!

As I described in this Forum on the 29th of November I'm making a new Ratinglist
based on 15 openingpositions. 10 of these are known from the CSS-Ranglist (for
further information check this website www.computerschach.de), here are the 5
new openingpositions:

C30 = Kings Gambit (1.e4,e5 2.f4)

E17 = Queenindian (1.d4,Sf6 2.c4,e6 3.Sf3,b6 4.g3,Lb7 5.Lg2,Le7)

B02 = Scandinavian (1.e4,d5 2.exd5)

D35 = Orthodox Queens Gambit (1.d4,d5 2.c4,e6 3.Sc3,Sf6)

A57 = Modern Ben Oni (1.d4,Sf6 2.c4,c5 3.d5)

It's my intention to create an élite Ratinglist of 16 engines so that each
engine has played 450 games (30 x 15) when the list is full. I'm testing on the
following Hardware:

Asus A8V Motherboard, Socket 939, FSB 1.000 MHz
AMD Athlon 64 4000+, 2.4 GHz, 1 MB Level 2 Cache, 90 nm San Diego Core
2 x 512 MB Corsair PC 3200XLPT RAM (CAS Latency 2-2-2-5)

And here are the specific testconditions:

Shredder 9 GUI
Thinkingtime for each engine: 40 moves in 14 minutes repeatedly
Hash Tables for each engine: 128 MB PC 3200 Ram (CAS Latency 2-2-2-5)
8 MB Cache for TB's
TB's: Nalimov - 3 und 4-pieces
Pondern OFF

I have already started the new testing and the first result were as follows:

Fritz 9 - Fruit 2.2.1 19-11
Shredder 9 - Fritz 9 18-12
Shredder 9 - Fruit 2.2.1 11½-18½

A couple of hours ago the test of Toga II 1.1 ended. I was very excited to see
if this Fruit-based engine would go all the way and conquer the topposition of
my ranking. As the results show it didn't quite make it:

Toga II 1.1 - Fritz 9 14-16
Toga II 1.1 - Fruit 2.2.1 10-20 (!)
Toga II 1.1 - Shredder 9 16-14

The results against Fritz and Shredder are probably quite expected but that Toga
suffered such a big defeat to Fruit was a surprise to me. Also the Drawfrequency
was a bit of a surprise: in the 90 games Toga played 38 draws = 42%! Thanks to
the huge victory Fruit 2.2.1 has replaced Fritz 9 in top of the ranking:

1. Fruit 2.2.1 49½
2. Fritz 9 47
3. Shredder 43½
4. Toga II 1.1 40

I have already started the next test and this time Loop List has to prove its
qualities. In app. 100 hours I'll have the result (one game lasts in average
50-55 minutes) and I'll post it here in CCC-Forum.

Best regards
Per
