ICOfY Base

The ICOfY Base is a free chess games collection and can be downloaded by anyone. It can be used with most free and commercial chess programs, which support the PGN file format. Periodically more chess games will be added, existing entries will be revised and duplicated games will be removed.

The ICOfY Base chess games collection want to be an alternative not a replacement of the commercial products of Convekta or Chessbase. It just want to offer the chess players of all levels a free possibility to prepare for a specific opponent or an opening system. For this reason, the ICOfY Base chess games collection does not contain any short games with less than ten moves and does not include tournaments, places, or rounds.

How an update of ICOfY Base occurs

Most of the time I spend with collecting the chess games from several sources. After that a semi-automatic process starts. First I change some information with a RegEx-Tool. Then I import the chess games into SCID and run several things (e.g. board search, strip PGN tags, add ELO ratings, add ECO codes, make player name corrections, and so on)

Now, I can export all games from the SCID database into one PGN file, which I import into a Chess Assistant database. There I can run the standard correction script over the database. After that Chess Assistant can find and destroy double games. The result dataset will be imported to the reference database (the last release with all following updates) and a final double games check runs.

That result dataset will be exported to PGN, I create the 7z archive, load it up to a mirror server, change the website und you can download the latest update file with only one click. Do you really want to do my work for yourself?

Frequently Asked Questions

I have downloaded a file. What I have to do now?

First, you need a decompression tool, which support the 7z-archive format (e.g. 7-Zip). Then you can decompress the file. After this step you have one (or more) file(s), which you can open within your chess software.
