The exclusive annotated database. Contains more than 4 millions games from 1560 to 2008 in the highest ChessBase quality standard. 62,000 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 2008. Mega 2009 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 220,000 entries, it made sense to use an adapted playerbase which includes about 248,000 names. Doing this, the photo database was extended as well to contain 31,000 pictures now.Return Information for Software & DVDsComputer Software and DVDs can only be returned or exchanged if the product is in its original,sealed packaging and has not been installed or used in any way.
