HO HO HO. We are going final days of the Year 2022. Marry Christmas from Opening Master team. As every year we have prepared something special. Let's go back to the times where no cloud downloads were possible. Who remembers sending DVDs to our chess friends? We got something special for you now. 



Seems like ancient times. It was just 10 years ago when we started to use the cloud service and put our chess database online. We started with Dropbox and soon realized the fullwrite access was not good. Then we tried for few years Sugarsync but the downloads where too slow and chess players were complaining. (chess files in PGN extension are 8 GB large). Some years back we started to use cloud on and we are happy ever since.

Do you want to get super cool small gift for your special friends or family member? We have prepared a special USB KNIGHT KEY with the latest Opening Master Chess Databases as a Christmas Gift plus many more cool stuff inside. The offer is valid until December 24, 2022

You can re-use the coupon code as many times as you wish. We have no limitations. Share with many as you wish. 


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.
