SSDF Rating List January 17, 2009

The Swedish Chess Computer Association – Svenska schackdatorföreningen, SSDF – is an organization that tests computer chess software by playing chess programs against one another and producing a rating list. On September 26, 2008, the list was released with Deep Rybka 3 leading with an estimated Elo rating of 3238.

The SSDF list is one of the only statistically significant measures of chess engine strength, especially compared to tournaments, because it incorporates the results of thousands of games played on standard hardware at tournament time controls. The list reports not only absolute rating, but also error bars, winning percentages, and recorded moves of played games. After it came under criticism because of its use of sub-standard computers the SSDF started testing with an Intel Core 2 Quad 6600 2.4 GHz with 2 GB of RAM-memory and a 64-bit operating system.

For the first time SSDF has tested a chess program made by Alexandar Naumov. When we began to test Naum 3.1 on Q6600 2.4 GHz it was his latest program version. After 358 tournament games it´s rating is 3046, which makes it the fourth strongest program on the SSDF Rating List.

Frans Morschs Deep Fritz 11 running on Q6600 2.4 GHz takes the second place on the list with 3085! Compared to Fritz 11 on Athlon 1200 MHz, the rating increase is 166 points. Deep Rybka 3 has now also been tested on Athlon 1200 MHz, which resulted in a rating of 3066. As expected Vas Rajlich's program is strongest also on this slower single processor. On this hardware Deep Rybka 3 has 141 points more than Rybka 2.3.1 A1200, and 161 points less than on Q6600 2.4 GHz.

FRITZ 11 and Deep Fritz 11

A year ago Fritz became the first commercial chess program in history to defeat a reigning World Champion in a formal match. Hundreds of thousands of chess fans followed the event on the Internet. In its games against Vladimir Kramnik Fritz displayed an astonishing degree of strategic understanding, underscoring its reputation as one of the strongest and best-loved chess programs in the world.

The new Fritz 11 – now availabe in the ChessBase Shop – has been vastly improved, compared to the version that beat the world champion. Its playing strength has improved by 80 Elo points. But it is also the entire package of new features that will impress chess fans. The program helps you with practical play, training and analysis, and does so in an entertaining way that fosters learning and understanding.

The main Fritz database contains over one million games, ranging from the years 1625 to 2007 – from the early beginnings of chess history to the latest top-level tournaments. The revised and extended openings book is more diverse and better tuned to the strengths and preferences of Fritz. A complete new feature, the “magic eye”, visualizes the thought processes of the engine on the 3D chessboard. You can directly follow the ideas that are going through the “mind” of the program.

Here's an interesting article on the Advantages of Deep Fritz 11, written by one of it's programmers, Mathias Feist.

System requirements: Pentium III 1.4 GHz or higher, 256 MB RAM, Windows XP or Windows Vista, GeForce5 or compatible graphics card with 128 MB RAM or higher, 100% DirectX compatible sound card, Windows Media Player 9, DVD ROM drive.
