This is the largest and most clean chess database found on the Internet. And the price remains the same as last year for 59 EUR. Within this price, you get approx 3-4 updates per year. Since the last period, we added more than 200K games. Hurry up and read our article on how to save 50% during the holiday XMAS season.

The OM CORR is for correspondence chess players who usually play on ICCF or similar Correspondance portals. The complete collection of almost 2 million games includes all tournaments, world series, and local games of ICCF players. The latest release includes 1,964,806 chess games.

As announced previously for enthusiastic collectors we published the best ever ultimate collection on the Internet between 1800 and 1987. We say, there is no other game that is not in this database.

How is Opening Master different from free databases?

Despite getting our games from different sources, we dedicate a lot of time to eliminate duplicates. We also normalize the names of the players, which amounts to dozens or even hundreds of corrections a month. The free databases are often very low-quality and cluttered with lots of duplicates. There is no such thing as free lunch. We ask for a fair price starting 39 EUR for one year. It is much cheaper than less quality commercial chess databases out there. Try it now. Until December 24, 2020, we offer a 50% discount on all our products just by typing the #XMAS2020 coupon at the checkout.

So what about the Chess Openings for free where can I download them to try?

Oh.. here is the download link. We almost forgot.
