Read again my comment, and you may understand.
The Grunfeld has a shitload of sub-variations, most of the requiring deep memorization.
Memorization isn't the problem, having the understanding behind the moves is what's important.
"I think 1. ... d5 is good enough for quite some time."
It's too passive and/or symmtrical for some and 1...Nf6 is a great way to set up breaking the balance.

Thanks everyone. ..!!!
that was my main concern if I get book that explains purpose of each move den I don't need to memorize everything. ...
d4 v/s d5 symmetrical position leads to which opening variation. ...??

hmm....I was asking from Black prospective. ...being black if I play d5 which is more easy system 2 play....whether QGD or slav or tarrash??
The one that happens the most in my games would look something like that:
But I'm not any good with openings, to be honest. Just play the moves that follow opening principles and better devote your time to studying tactics and endgames.

Thanks again. ..I was wondering how did you paste above game....I mean where do we have dis option??

Based on what I know, the best book to start off with for the Grunfeld is Rowson's book. It is a bit outdated, but it shows you the purpose of the moves in each line.
After that, you should get the latest Grunfeld book from Everyman chess (or you can look through ChessVibes Openings or CBM) to get the latest lines that Grandmasters like to play.
The Grunfeld is a very powerful opening, but as pfren said, there are a lot of theoretical lines. One blunder, and you could be lost almost instantly. There are also some tricky move order issues that might force you into the KID.

Memorization isn't the problem, having the understanding behind the moves is what's important.

Disagree, for most openings you would be correct, understanding moves is what will permit you to play it well.
But it is not so for the grunfeld, like pfren said, the grunfeld has a ton of long computer analysed variations which are based on pure tactical resources rather than strategic principles. This makes memorising movesa must if you dont want to get miniatured.
By extension this makes the opening inappropriate for non pros, as an amatuer could use their time so much more wisely than learning all the variations in the Rb1 exchange.

Yes....having knowledge of how to play certain openings is always useful otherwise you will get kicked out very soon. ...I used to play earlier e4 but I found it difficult to play Sicilian defence with both colour hence switched from e4 to d4....but its quiet difficult to study all d possible replies available for Black b it d4 or e4.....since which system our opponent would play you never know. ...
Hello Guy's. ...
Could you please suggest me book on Grünfeld Defence from Black prospective....I m basically looking for d book which focuses more on explanation of what exactly Black wants to achieve with Grünfeld Defence and goals, idea because I m new to dis opening. ...want to learn more theoretical part.
Any book which actually explain move by move approach of Black behind playing certain continuation would be much helpful.....
I m not looking 4 book which gives long computer analysis with lesser explanation.
your reply is highly appreciated!!!
Thanks in advance. ...:)
