The most recent games of the database are from the middle of November 2013. Mega
2014 also features a new edition of the playerbase (requires ChessBase 12!). As usual,
this is where most of the work was done. As the player index now contains already
more than 293,000 entries, it made sense to use an adapted playerbase which
includes about 350,000 names. Doing this, the photo database was extended as well
to contain 33,000 pictures now.
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.

needs to know which database it should use for reference purposes and will usually
suggest the largest one it finds in My databases.
If that is the right one simply click OK. If you want to make another database your
