Why Opening Master chess 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. Now you can save even more.
What can I use Opening Master for?
The OTB players most often use the Opening Master database when preparing for an opponent. They look up games played by their future opponent in the database and prepare themselves for the opening. The database is also very well suited for preparing the rest of your repertoire – one can easily find out what variations are being played at what rate of success. There is an important difference between OTB and correspondence games, however: correspondence games usually feature openings that are completely different from practical chess. With Opening Master, you don’t have to rely on your memory and can freely enjoy all kinds of complicated moves – all of them are easily accessible via the database! The database is frequently used by correspondence players even during the game for looking up whether their position has already occurred in other games, how and by whom it was interpreted, and what are the statistics for it.
