Q: How can I make software works under Windows Vista OS?

A: We have three standart ways for any problem under Windows Vista

1) Right clicked on the icon and chose Properties. Then chose Compatibility tab. Chose the Windows 2000 emulation option

Note: You should disable User Account control before installing our programs.

If it doesn't help - use patch 920 to change the program protection, this patch (920) works for CA 9 only.


Q: I follow the instructions but I can't link Rybka*.exe to Fritz, what's the matter?

A: If you have connected Nalimov Tablebases to Fritz then try to do the following:
1. Put the exact tablebase path in "Extras/Options" of the Fritz GUI,
when Fritz is the active engine.
2. Quit the Fritz program totally.
3. Start Fritz again. It will now have Fritz 9 as active engine.
Tablebases are working. (Try!)
4. Deactivate the path to the tablebases, for instance by changing
"Nalimtbs" to "Nalimtbs0". (So you don't have to seek the path
afterwards again.)
5. Load the Rybka engine. The will be no error, and Rybka will use the
tablebases now.
6. Before quitting the program, change again to Fritz 9 and rename the
tablebase path again correctly.
7. Next time start with 3.

1) Download the file
2) Unpack it. After unpacking the program the folder CT-ART 3.0 will be created.

Q: Why does Fritz (or another well-known strong program) calculate more variants in a second than Rybka (and sometimes much more than the latter)?

A: Rybka is a positional program. It calculates fewer variants, but does it more thoroughly. Moreover, the quantity of variants in a second is not the main index of program’s force.


Q: I installed Chess Assistant, but notation display incorrect symbols instead of chess fonts.

A: If some problems with chess notation occur, try to reinstall manually our CA Chess font from sub directory Fonts or reinstall the fonts from the following links: http://chessok.com/files/PRG55CHE.TTF

A: Rybka multi-processor version supports all processors. However the 8 processors are used with the most effect.


Q: How to adjust the program Rybka to make it play in the strongest way?

A: For default all settings of Rybka are the best. You may increase its strength by adding more RAM for Hash tables, adding Nalimov Tablebases, using more strong Opening Book or using more powerful computer.


How to reactivate CA9 or Rybka

A: If you bought version on CD/DVD, then you should reinstall it.

You can specify, whether you serial number is correct by writing to info@chessok.com


Q: I’m a 1400 rated player. What software would you suggest I get to improve my game?

Chess Tactics for Beginners allows a student to cope with the elementary tactical techniques, while Advanced Chess School contains extensive theoretical material on the basic chess methods (Opening, Middlegame and Endgame): as many as 450 study examples in total. There are also about 750 exercises intended for solving and playing.

After studying these two programs your rating is likely to go up to 1700 which means you can proceed to CT-ART 3.0, Strategy 2.0 and Encyclopedia of Opening Blunders.


Q: What is a chess engine?

A: A chess engine recommends moves and provides evaluation scores for chess positions. It should be used together with a chess graphical user interface (GUI), which will provide intuitive graphical interaction with the engine.

The major chess graphical user interfaces (in no particular order) are:
· Arena
· Chessbase/Fritz
· Chess Assistant
· Shredder
· Chess Partner

From this list, Arena is free and is easily the best free chess graphical user interface available. It can be downloaded from here
