Thousands of chess players enjoy Chess-DB every day, for free. And we enjoy making the site even more unique and useful for you.
We generally would like to keep the site free for everybody, but we have some cost of running the website and those costs gets especially higher for some of the advanced functions that we provide. You can support our efforts by making a small donation, and enjoy several special and exclusive features as a result of this.

Chess-DB rare database
This is our database of rare chess games, i.e. such that are either hardly available elsewhere on the web, or are available exclusively only on Chess-DB.com. We use various sources to compile our exclusive database, for example: rare chess books and magazines, video-recorded chess games, scoresheets, personal databases and others.
Note: Chess-DB rare database is currently in early testing and only very little games are published in the chess-db rare database.
