Hello Russell!

Here you see my testconditions:

First of all the 10 fixed openingpositions that I am using for my tests:

1. Queens Gambit: 1.d4, d5 2.c4
2. Kings Gambit: 1.e4, e5 2. f4
3. Stonewall: 1.d4, e6 2.c4, f5 3.Sc3, d5 4.Sf3, c6
4. Caro Kann: 1.e4, c6 2.d4, d5
5. English: 1.c4, c5 2.Sc3, Sc6
6. Russian: 1.e4, e5 2. Sf3, Sf6
7. King- or Grünfeldindian: 1.d4, Sf6 2.c4, g6 3.Sc3
8. Sicilian: 1.e4, c5 2.Sf3, d6 3.d4, cxd4
9. Queens indian: 1.d4, Sf6 2.c4, e6 3. Sf3, b6 4. g3, Lb7 5. Lg2, Le7
10. French: 1.e4, e6 2.d4, d5

Every engine has got to play each openingposition with both white and black
meaning that a match between 2 engines consists of 20 games. I find that the
chosen fixed openingpositions provide a fair mix of open, tactical and closed
positional openings. It's my aim to create a ratinglist of 25 top-engines.

I'm running my tests on this 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:

Windows XP Pro
Hiarcs 10 GUI
10 fixed openingpositions, all openingbooks for the engines are OFF
Thinkingtime for each engine: 6 min. for the whole game + 6 bonussec. pr. move
Hash Tables for each engine: 64 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

As you see Russell I'm not doing my tests on Blitzlevel. 6+6 means 12 minutes
per engine for an averagegame of 60 moves. Although I'm not testing on
blitzlevel I disagree with you regarding the strength of Toga on Blitz. Take a
look at the CEGT 40/4 ratinglist and you'll see that Toga II 1.1a is only 7
points behind Fruit 2.2.1 and 17 points behind Hiarcs 10 Hypermodern. It's very
close to my list in which Toga is 14 points behind Fruit and 16 points behind
Hiarcs 10. In other words, you are wrong when you claim that my ratinglist "is a
bit off".

Best regards
Per
