3...d5 is TOO early and a big mistake.
Ceding around 15-20cps evaluation advantage at least.
Add to that the 15-30cps first move white advantage, and, with optimal play, the Gruenfeld is ON THE EDGE of losing for black.
Not quite, but almost.
Troll or not troll, 3...d5 is a bad move and one day, with much stronger engines and deeper analysis that will become evident.
Do people really think all openings could be equivalent?
Please behave yourself Lyudo. I am not a computer. I do not think or play chess like a computer. I am human. A 10-30 cps means nothing to me, absolutely nothing. Plans and conceptual ideas though I find very interesting. As I will not be playing much against computers because I already know I cannot beat them I would appreciate some human analysis.
The empirical evidence is that among humans its a perfectly fine and respectable opening leading to double edged positions which are very exciting.
I behave myself perfectly.
Conceptually:
3...d5, 4. cxd5 - trades semi-central c for central black d pawn, bad
4...Nxd5 5. e4 - gains tempo by kicking the black knight, bad
Black is playing black, bad.
3 small white advantages add up, bad.
Overall, a very neat conceptual framework.
I would abstain from playing the Gruenfeld, unless drunk.
?
Do you have a specific line in mind? I mean it's not like we're analyzing a tactical opening as heavily analyzed by engines as the Grunfeld, but at least - oh n/m we are...
Seriously though, what do you think is best path forward? I suppose I would favor the modern Be3 lines, but maybe you like the Classical. White has a big center - well yes, that is obvious. If Black can trade on c3, I don't consider this a tempo loss. Black has interesting dynamics in return for White's classical center. This opening is a headache for top players - well maybe you want to keep your secrets...
It's nice to see somebody actually interested in learning a new opening, instead of the demented obsession with the first ply which has become typical of this forum. Afraid can't help you much though because Grunfeld has never appealed to me much. Awhile back Rowson wrote a decent book which highlighted the different plans available, maybe something like that would interest you
Thank you for your kind sentiments its very much appreciated. Will check out the Rowson publication for sure. I actually really like the games and positions that results. I think its their double edged quality, one false move and someone is walking the plank into shark infested waters for sure.
Use Rowson's book to learn the opening, and Avrukh's book as your 'go-to-encyclopedia' after your games. My brother used to play the Grünfeld for many years and he spoke very highly of Rowson's book. Good luck with your new opening choice! Btw, I can only echo TwoMove's sentiment, don't worry too much about the engine.
