Download Opening Master Database 2.03 for Free !!!

OPening master database
The history 
The chess database Opening Master has been on the market since 2004 when it was registered under the copyright protection. It was marketed mainly in Central Europe where its roots are coming from but it reached so much popularity then it is ready for entire chess population. Back then it was the pilot ''alpha'' project after about 3 years of research and development and had around 4.2 millions of non -commented games.
The first database was in dual format and could be used by two Chess Database Programs (readers of data)
1) ChessBase / CB   and   2) Chess Assistant / CA
The world leader among the chess programs which can read databases according to the statistics is currently the Chess Base. It was very difficult for authors to keep up with the two formants simultaneously therefore the decision was made to start using only the Chess Base software program for reading and analysing the Opening Master data. It was not until early 2010 when we introduced ''again'' the coversion for Chess Assitant realizing the market potential including the older ChessBase file CBF which can be used under EXACHESS environment (MacUsers). More than that, the PGN format is also very popular among users as we converted also to this environment.
The programs
CB is more 'user friendly' program but you pay for this user friendliness much more money plus get "real" updates roughly once a year.. The CA has on the other hand more advanced menu and operations are much faster there, It is more suitable for advanced chess players and for massive data handling. It can also handle de-duplication of commented games which after so many years CB is not able to bring it to the market. The CA updates online which is a great advantage.
But coming back from Database software to actual DATABASES. Why the Opening Master was born? One must say, that to buy every year the same product with only small updates and no big value-add is bit strange, and yet there are thousands of players who buy commercial products like this. It's all about marekting how great name you give or how great cover you produce. The DATA inside? Forget it, people won't notice. But guess what, some actually do. The one year period is also very long waiting time for a good chess players, there are so many things happining during this time, thus more frequent update might be necessary if not required. Both CB and CA are now updating their databases more frequently however the quality of the updates is questionable. (make comparison between 3 products and see)  For beginners 2 years time is ok, until they figure out that the old data is actually hurting them and then they will seek for an update.
Some practices of inserting data into the commercial databases are very disputable, consider games without bodies. Who needs such games? Just for the stake of increasing the number of the database? Thanks but, no thanks. And what about games prior 1900? Well, here we may say, they play chess at that time too? But our opinion and focus is mainly 20th century that changed the way of thinking and analysis over the chess board, thus you won't find any historical games prior 1900 in the Opening Master Database.
