New OM 1.24 goes universal
We are happy to announce a new milestone in Opening Master development. As the new technology goes forward, we are now able to migrate different databases from one format to another while still being fully functional. This was not possible few months / years ago. format2.pngThe new release of Opening Master 1.24 holds 5,762.539 human games with focus on zero duplicates and quality games. The sub-databases are as usual also part of the main deck. They are used by many players and for example OM 2500 holds now 184.550 games where both players have more than 2500 ELO!. Another powerful database OM 2300 holds more than 1 million games with players with more than 2300 ELO. (1,044.128 games)format2.png
This month for the first time we are introducing the BIG OM also in PGN format and CA format. From now on, you are able to upload your database to your favorite chess database program be it Chess Base, Chess Assistant or SCID environment. As always you may find different opening reports in our Opening Selection, screen shots, PDF reports etc... As generally the files are very large we use compression tool RAR to save some space.
