Upgrade Mega Database 2011 from Mega 2010

 The exclusive annotated database. Contains more than 4.8 millions games from 1560 to 2010 in the highest ChessBase quality standard. 65,000 games contain commentary from top players, with ChessBase opening classification with more than 100,000 key positions, direct access to players, tournaments, middlegame themes, endgames. The largest topclass annotated database in the world. The most recent games of the database are from the middle of November 2010. Mega 2011 also features a new edition of the playerbase. As usual, this is where most of the work was done. As the player index now contains already more than 257,000 entries, it made sense to use an adapted playerbase which includes about 270,000 names. Doing this, the photo database was extended as well to contain 32,000 pictures now. Incl. Online Mega-Update 2011: With ChessBase 10 or 11 you can download games for Mega 2011 for the whole year, a total of approximately 200,000! That means your Mega 2011 will remain up to date from January to December.
