The massive database online is Chesslive.de.
To study the above opening go to the site and enter the moves.
To properly use the site, study the games of the GMs.
Reject the garbage games, which are at the end:
Online games, postal games, European Children tournaments.
If the database shows 2000 games, and you want newer games go to
advanced settings and change the start and end year. (Such as 2001 to 2007).
To download games use your mouse. Next to the game(s) mark an asterik,
by clicking your mouse. DO NOT TRY TO DOWNLOAD a whole lot of games or you will get a crash. Do about 50 games at a time.

Another site: Chessgames.com. You can download entire collections, but you must be a paid up member. The cost is reasonable.
