The exclusive annotated database.
A ChessBase Account is linked directly with ChessBase. Many functions of the web apps complement this intelligently and provide a maximum amount of chess information.
A novelty for all users of the web apps: all annotated games from the Mega database are now available online to every premium user. It will in the future be possible to load these annotated games directly both from CB 14 and from the web apps, e.g. the Live database.
Like that, Premium subscribers have direct access to the annotated games and are no longer obliged to access them only from their copy of Mega on their local computer. Therefore you can now look at, play through or analyse the annotated games wherever you may be with your smartphone, tablet or any computer with internet access!
Some noteworthy points about the Mega Database:
Carefully corrected gamescores
A large percentage of the games originally appeared in annotated form in ChessBase Magazine. In the process of annotating the games many errors in the game notation were discovered. They were also screened by other experts and went through numerous other quality controls before they were included in the Mega Database.
Unified spelling of players' and tournament names
Without standardized spelling of players' names a number of database functions would become less reliable or useless (player dossier, preparation for specific opponents). ChessBase invests a lot of effort into correctly identifying all the players in a tournament and making sure all spellings are standardized.
Careful editing of Elo ratings
All statistical analyses in a database rely on complete and accurate rating information. This is especially true of openings statistics, the success rates and evaluation of variations, repertoire suggestions, sorting of games and many other functions that use information on the relative strengths of different players. So ChessBase takes great pains to insure that Elo ratings are included correctly for every player in every game.
