Hello Chesscomputerfriends!
As I wrote in this Forum February the 8th I'm making a new ratinglist. I am
still using fixed openingpositions in stead of the openingsbooks of each engine
(or a common book for all engines). Here are the 10 fixed openingpositions 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. I would like to thank Klaus Wlotzka (running the
CSS-Ratinglist) for support and advices in the whole process.
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
Lately I have been testing the new Spike 1.1 and here are the specific results:
Spike 1.1 - Fruit 2.2.1 9-11 (!)
Spike 1.1 - Hiarcs 10 8½-11½
Spike 1.1 - Toga II 1.1a 9-11
Spike 1.1 - Shredder 9 11½-8½
Spike 1.1 - Fritz 9 11½-8½ (!)
Spike 1.1 - SmarThink 1.00 11-9
Spike 1.1 - Ktulu 7.5 11½-8½
Spike 1.1 - Loop List 600 13-7
Spike 1.1 - Naum 1.91 12-8
Spike 1.1 - Glaurung 1.0.1 11½-8½
Spike 1.1 - Ruffian 2.1.0 12½-7½
Generally I find these results very impressing. A total score near 50% against
the 5 topengines is simply amazing. In the latest rating Spike 1.1 take up a
position as number 6 and not far away from Shredder 9 and Fritz 9:

11 Glaurung 1.0.1 : 2588 42 42 220 38.0 % 2673 20.5 %
12 Ruffian 2.1.0 : 2568 39 39 220 35.0 % 2675 31.8 %

All engines are playing with their default-settings with exception of Hiarcs 10
which is being tested with Hypermodern ON.
Congratulations for Schäfer and Böhm for making this excellent engine which at
that is a free-ware engine. Besides from Toga II 1.1a there is no doubt that
Spike 1.1 currently is the strongest free-ware engine.
As soon as Rybka 1.2 is available I will naturally test this extraordinary
engine but in the meantime I'll make other tests for my ratinglist. Next engine
to be tested: Gandalf 6.
Best regards
