For openings research the Reference search is one of the most important tools in ChessBase.

 

When you investigate opening variations the program makes available with its access via optimised search routines informative displays for the evaluation of various continuations. Even in searches in the early stages of the game, where of course extremely large numbers of games are collected and evaluated, the search function very quickly produces meaningful displays of information.

In the example being displayed the user can see at once that the Advance Variation was frequently played towards the end of the 1890s.
