Big DataBase 2025: In search of a treasure trove

Among ChessBase products the Big DataBase stands in its own right. Unlike the MegaBase it has no annotations. This paves the way for independent study and preparation, and helps the player to hone skills on his own. The present edition offers 11 million games from 1475 to November 2024. In this vast collection there are games from world championships, famous tournaments, past and present, not to mention little-known events that deserve greater recognition. There are magnificent battles, brilliancies and unknown gems all waiting to be discovered. Our columnist here introduces a few rare gems.
