Good book or course on the Grunfeld

As a Petrov-player (always defending, never attacking) I wanted more fighting games and bought "Attacking French" by Simon Williams. It worked!

Against d4 I play QGA but think about returning to the Grunfeld to get more fighting games. Does anyone know a good Grunfeld book can anyone recommend another book to fight (aggressively) against d4?

The Grunfeld and the French don't really mesh well together.

More typical of French players is either the e6-Dutch lines, King's Indian, or Nimzo-Indian, all of which are aggressive lines.

Here is an example of a very aggressive line of the Dutch that beat an FM:

Thanks! I have a book on the Dutch "Winning with the Stonewall Dutch" by Johnsen and Bern.

If you like fighting chess dont play Grunfeld

I know one that can get you playing a grunfeld, BUT BRO IT HAS ONLY 12 TRAINABLE VARIATIONS HELL NAWWWW

I have that one too. Very well written. A little dated from the theory perspective, but will get you all the fundamentals to play it properly. I would still suggest reading it, but then follow up with Sedlak's book, Playing the Stonewall Dutch.

And being a French player, you can start with 1...e6 and avoid many of the Gambit lines and anti-Dutch lines like 2.Bg5.

Thanks for the 1. .. e6 advice!
