The Ponti Chess Club Engine Rating List - February 2007 --------------------------------------------------------------------------------------------- Engines played at least 10 games. No versions! I think there's no sense to play _n_ versions of the same engine against older versions and then give a rating to them... that's why rating lists with that kind of approach are getting useless, in my opinion. Most of the games played with "blitz" and specially "bullet" time controls. Games are played with "ponder" ON. Hardware: Dual Athlon MPs 2600+, 1 GB RAM, ASUS A7M 266-D Motherboard OS: Windows 2000 Professional SP4 Engines play _most_ of the time using their own (the author's) opening books. Hash tables= 16 MB for each engine. Nalimov tablebases enabled (3,4 and most 5 pieces). Ratings calculated by ELOSTAT (Start ELO=2600) Chess GUIs used: UCI, Chessbase (Fritz), Winboard, ERT, Millenium Chess System, Chessmaster 9000, Arena. AUTO232 used when needed (e.g., CSTal). Ok, if you want another approach to calculate those ratings please take a look at http://www.geocities.com/Colosseum/Track/7733/mixed.htm --------------------------------------------------------------------------------------------- Program Elo + - Games Score Av.Op.
