Thank you for your excellent feedback.
How should black play for a win against 1. d4?

Maybe the Dutch Leningrader is something interesting if you want to have a double-edged position with a kingside attack from black.
Great players win all the time from the black side of all these "drawish" openings. How do they do it? They make a lot of good moves! Do that and you can play any opening for a win. Make poor moves and you can play any opening for a loss

It is definitely a way to go if Black is fine with defending an isolated Queen pawn.>>>
If you don't want to play with an isolated pawn structure then you shouldn't think you can play for a win with black.

I agree. I like the ideas behind having a pawn that tends to tie up minor piece like a Knight to stop it. There are some Tarrasch lines where Black plays an eventual d4 that are interesting but all in all, I like some of the positional aspects that come from d4 d5 openings. Now playing as White however, is a different story.

Openings that include a Fianchetto (either side) are very good if you want imbalanced positions with chances for either side. The Queen's Indian Defence is the most solid and sound of the openings, and is good if you want a nice imbalanced position without taking many risks. The King's Indian Defense is a good attacking line, and handy against lower rated opponents
Queens Gambit Accepted, Queens Gambit Declined, Slav, Semi-Slav, Nimzo-Indian, Queens Indian, Kings Indian, Grunfeld, Benoni, Dutch, these are some of the many openings you can confidently play fro a win as black

Everyone not considering the austrian attack and it's great
I'm very sure that you're in the wrong topic.

I think I'm going crazy but why is it that all the users from Spain are recommending the Austrian Attack? It's such a niche opening, and if it was just popular on chess.com then at least people would know that it's actually called the Austrian Defense not the Austrian Attack (I presume you mean 1.d4 d5 2.c4 c5). Do you just have multiple accounts? I'm not meaning this as an attack or insult in any way and I'm quite happy to admit I myself have had more than 1 account on this site. Just curious as every couple of months another user pops up recommending this.
(Also please don't take the above as racist in any way - I have nothing against you or other Spanish users and if people object I'm happy to delete my comments)

1.d4 nc6
if 2.d4, play 2.d5 or 2.e5
if 2.c4 play 2.e5 or 2.d5 (2.nf6 is playable too, but 2.e5 is the superior order)
if 2.nf3 , then play 2.d6 aiming for a pirc/kid structure or 2.d5 chigorin style.
if 2.d5, learn to play the Mikenas with ne5, or just play nb8 and pirc it.
you will never be bored as black again.

I have been playing the Modern Benoni for 20 years but people seem better prepared against it than they were and I've had some losses even against weaker players. I didn't want to play the QGA, which I consider difficult for black to win with so on Sunday in a county match I played the QGD for the first time for 20 years. I won in 32 moves although I had to play very slowly because I've forgotten what the basic positions look like from the black side. I'll be playing it again.

You're very wrong ... or why don't GMs play it? It should be a recognised opening if you were right. I think that in practice, between competent players of equal strength, white will win three out of four. The natural formation to go for is probably an Austrian Attack and white can sac a pawn in the centre.
one of the ways as Black that I am starting to adopt is to play the Tarrasch Variation of the Queen's Gambit Declined. Black can adopt this defense through a multiple set of openings by White. Play can go 1.d4 d5 2. c4 e6 3. Nc3 c5 and White can play either 4. cxd5 or 4. Nf3 as well as other replies. Black usually develops his Knights in alphabetical order and the dark squared Bishop to e7 and castles short. I read through a book by Eric Schiller titled A complete defense to Queen's pawn openings. It is definitely a way to go if Black is fine with defending an isolated Queen pawn.
IMO the tarrasch is a great choice for a lot of reasons. Educational (IQPs and hanging pawns), imbalanced (when you want it to be), very hard to crack (when you play it a la Kramnik, semi-tarrasch), and you initiate it early (on move 3) so there aren't a lot of ways for white to avoid it.
