There are 2 systems on ICC where games by top players are stored.
1. The SEARCH database contains games played by the top players ON the ICC. It has over SEVEN MILLION games and is growing daily! We currently add any game in which one of the players is an IM, GM or WGM. Bullet games are not added. We also add any game in which both players are rated 2300 or higher and the time control is longer than 3 0.
Example: Type on the command bar under your Main Console 'search Dlugy eco=A56' This lists games in which Dlugy was a participant and the ECO code was A56. You can click on a game in the list to open it.
Please read "help search" for more information.
2. ICC has LIBRARIES which contain games of major chess events, from the past and current, from all over the world. Read "help Cool-Libs" for a list of libraries.
