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 at 39 EUR for one year (OM CORR). It is much cheaper than less quality commercial chess databases out there. If you do not wish to prolong the subscription, just cancel it, you may keep the databases for ever for your personal use but will not receive updates.

Have you heard that we prepared a list of the top 52 chess openings for you? They are completely free where and no credit card or sign-up is needed.

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