Who plays Grunfeld and why is it awesome?

Yeah, I have not much sex these days either.

That's what makes the Gruenfeld challenging. You never know what white plays. Among antiGruenfeld, Only the Tromposky is worth studying.

Lol, my Celtic cousin, Slainte to you for the New Year, for Mrs Pulp, all the kids and all the ones you love!

Same for you!

I began playing the Sicilian against e4 which evolved into an accelerated dragon Sicilian & Hyper - accelerated dragon which have the king side  as a fianchettoed castled position and another site that I played against the computer said I should play the KID and I have been playing it fairly successfully but I like what I've seen of the Grunfeld in this thread; to me, it's like the KID with a one, two punch with d5 and then c5, so I'm gonna give it a try.

I'd prefer to eat less chips and lose more weight.

Grunfeld is an excellent opening for all levels. At a higher level, deep memorization is key, but at a lower level, understanding of the dynamics is the cornerstone of success. Overall, if you play the Grunfeld, your chess skill in general will improve. Highly recommended. Some key players as black you should look out for are MVL, Peter Svidler and Kasparov

Thank you Fide Master it gives one confidence.

As I mentioned above, Svidler considers the Grunfeld to be a bad repertoire choice because of all the memorization required for Black. But perhaps there are short-cuts for lower rated tournament players.

I do agree that for players below a certain level, it’s all just chess and the strategies involved in the Grunfeld can be an excellent building block for future understanding.

Smyslovfan you bad ol puddy cat, how are you!

The grunfeld is a top level opening that is difficult for black to lose early and is difficult for white to maintain a lead. 

Svidler, Vachier-Lagrave, and AlphaZero play it.
Smyslov, Fischer, Kasparov used to play it.
It is awesome because black gets a queen's side pawn majority and thus a distant passed pawn b6 and thus black wins the endgame if he can defend against white's attack based on white's strong center d4-e4.
The Grünfeld is so strong, that some grandmasters like Korchnoi played the English opening to avoid the Grünfeld: 1 c4 Nf6 2 Nc3 g6 3 e4 Bg7 4 d4 and black is in the King's Indian Defence.
In the Yekaterinburg Candidates Tournament the Grünfeld was played 5 times: 5 draws.
Those 5 games are a good start to study the state of the art.
