I have a correspondence game when using database is allowed but using engines is not allowed.
I am using rybkaII.ctg because it is a database
and not an engine and I wonder if you can give me some games that include the database that rybkaII.ctg is based on them.

I read in rybkaII.ctg the following information:

16 move x 4 0 2739 1904
16.move y 0

It means that white always played move x against very strong players and always lost.

If I search in I can find only a single game from 2001 when move y was played when the game was drawn.

I wonder what is the reason for this and why rybka's book include games that I cannot find in that database or maybe I should search in a better database.

I also wonder if the games that rybkaII.ctg is based on them are public games or private games

A lot of those games are based on computer chess engine games on the Playchess server, so will not be seen in human play.

The main question is where I can find them.

I do not expect to get the exact collection of games that were included for the rybka book but the question is if I can find somewhere collection of games that include all the games that were used for the rybkaII.ctg book(rybkaII.ctg can include moves not from the games if the written frequency is 0).

AFAIK you won't find these games in public.

Hmm, not quite so, I have a link to some site, but the site was down for me now. Here it is anyway:

There may not be a complete overlap on the RybkaII games, but there are engine games out there to be collected that at least come close to the games used in the RybkII book (playchess games rather than human games).

just for caution, if you use a database made of computer-computer games, you may be accused for cheating, and actually the moderators wouldn't have any chance other than banning you. there's no way they can assume you're not using an engine. so, probably the site has also not allowed databases with computer games, make sure you read the rules carefully.

In RHP, AFAIK, it's not allowed.

What do u means ????????
Parent - By bedouin (**) Date 2007-07-22 12:42
What he means is that if Uri is playing in an event where database is allowed and engine disallowed then he could be in trouble for using a database/opening book from engines because it wll have an engine footprint and those games are not available in a human database.

Visit for a good selection of computer games and a selection of non-commercial opening books.

Its a very slow download (meaning start the download and go out to dinner or to bed) because of the limited bandwidth.

wow, very nice link, if the server would be faster....

Mr pakman you can give your files to be added to the games collection at the chessbase games site. Some people like Waesch with huge games have given their games which contribute to the opening books and databases available today.

Thanks for the suggestion.

I am on the chessbase site as Norm Pruitt.

Not much from me yet but the machine game collection has been started by ECO code.

Thank Again

There is a 240,000+ game correspondence database at

The database does not have the latest games, but may be an addition to your data.
