There is a total of 10826 games with an average rating of at least 2570 (except games with annotations and those of Grünfeld experts Vachier Lagrave, Svidler and Ftacnik).
A double click on the database loads the games overview. A further double click loads the relevant game. The tab Players lets you sort the games according to frequency (with the tab Total). At the top there is Lubomir Ftacnik with 447 games. It is also worth studying the games of Maxime Vachier Lagrave and Peter Svidler, who have played almost all their 409 or 437 games with the black pieces. Furthermore, it is interesting to click on Title; (for that you should have an up-to-date player encyclopaedia) you can see that almost all the world champions had or still have the Grünfeld Defence in their repertoire.
The games can be played through or further investigated with an engine or a Powerbook.
