There is no opening giving black advantage on 1.d4...

Congratulations Kindaspongey for finding the OP an advantage against 1.d4

You must be very proud for your help.

Englund's Gambit (1...e5) allows for some fun queenplay early on, the main line is actiony and fun to practice/memorize, and people who play the London system blindly will be out of their comfort zone by move 2.

Indian defense 1...Nf6 is the most popular and certainly the best move to counter 1. d4.

I usually play d5

old benoni

Nimzo and Slav

Nowhere was such a claim made by me.

nimzo/slav/benoni

What a complete and utter joke!  I myself play 1...Nf6 against 1.d4, but there are two major flaws with your logic:

1) 1...Nf6 is NOT best.  If one can actually argue any move is "best", it would be 1...d5, but 1...d5 and 1...Nf6 as far as I'm concerned are equally strong.

2) 1...Nf6 does not equate to an Indian Defense.  More moves are required to determine that.  For example:

   1.d4 Nf6 2.c4 e6 3.Nc3 d5 is NOT an Indian Defense, it's the Queen's Gambit Declined

   1.d4 Nf6 2.Bg5 is NOT an Indian Defense, it's the Trompowsky Attack

   1.d4 Nf6 2.Nf3 d5 3.e3 e6 4.c4 dxc4 5.Bxc4 is NOT an Indian Defense, or the Colle System for that matter, it's a direct transposition to the Queen's Gambit Accepted (1.d4 d5 2.c4 dxc4 3.Nf3 Nf6 4.e3 e6 5.Bxc4)

1.d4 Nf6 2.c4 g6 3.Nc3 Bg7 is the King's INDIAN Defense

1.d4 Nf6 2.c4 e6 3.Nc3 Bb4 is the Nimzo-INDIAN Defense

1.d4 Nf6 2.c4 e6 3.Nf3 b6 is the Queen's INDIAN Defense

There are others of course.

im looking forward to trying some of these lines out , 1 d4 is a good thing to face ive found ,

I like the Slav and its cousin the Caro-Kann for Black against 1 d4, 1 c4, and 1 e4.  Andy Soltis has a good overview of both: it is the basis of his A Black Defensive System for the Rest of Your Chess Career.  The Lakdawala book on the Slav previously mentioned by kindaspongey as well as Lakdawala's book on the Caro-Kann are good move-by-move explanations of what's going on and why.  But note that you are likely to be out of the book by moves 2 through 8, so it's MUCH more important to understand the ideas behind the openings you play. Soltis is complete enough for that purpose at your level.

I usually play 1...c6 vs 1 d4 or c4 or e4 - hoping for a transposition to the Slav or Caro-Kann and getting a decent position in any case. 1 d4 c6 1 e4 d5 transposes into the Caro-Kann, my favorite of the two.

Both openings support a c6 and d5 pawn structure, allowing the Black Queen's Bishop to move to f5 or g4 -where this "Bad Bishop" can be traded off for a B or N at first chance- before Black plays e6 and blocks it in as occurs in the Q's Gambit Declined vs 1 d4 and French Defense vs 1 e4.  The black d5-Pawn is often traded off which often makes a great outpost for the Black f6-N. The Black QN is often posted at d7 (the QB isn't there to be blocked in!) which takes away potential White N-outposts on e5 or c5 and attacks any White pawns at those positions as well as supporting the Black f- and b- Pawns that attack them.  While castling Queenside is not often recommended, either opening is flexible enough to support a K-side or Q-side attack, usually beginning with Black's f- or b- pawns poking holes in White's typical advantage in space.

These openings can be wide open or very closed, usually determined by White playing an exchange variation (open) or advance variation with a pawn on d4 and another on c5 or e5 (closed): two of my Slav games back, my opponent and I only traded off a pair of N's in the first 20 moves (I won: https://www.chess.com/daily/game/161623416) and in the current Slav Defense I'm playing we each traded off a Q, B, N, and 2P's in the first 10 moves.

nimzo indian or queens indian.

1d4 knf6 c4 , does allow for modern benoni , i guess for me thriller fan 1 d4 d5 and i feel like thats saying ok to white do your stuff ,

im a benoni fan it asks a question of white (old benoni) straight away , i dont mind modern benoni either thats got flexibility ie it neednt go that way

1.d4 is simply + -. Black can try to defend but not more.

Another clown response.  Just like how there is no way to force an advantage for Black, there is equally no way to claim that White wins after 1.d4.

In essence, there are no less than 7 legit responses to 1.d4, and even some offbeat stuff may be ok as well, but you can't argue against the following 7 defenses:

1) QGD (1...d5 and 2...e6) - I can play it, but personally, don't like that Black has very few winning chances.  Often when I do execute this, it's because I need a draw.  Sure a win is great, but not necessary in such a case, but a loss may be catastrophic.  Often the case in late rounds.

2) QGA - Totally sound, but I don't play it.

3) Slav/Semi-Slav - I get good results in the Bishop Sac line, where you often end up with 7 pawns against White's 4 pawns and a minor piece for an endgame, but I hate facing the Dutch variation, so I tend not to play this.

4) Nimzo-Indian Defense - Coupled with either the QID, Bogo-Indian, or Benoni, this is fully sound, and considered my back-up defense.  I will usually play the QGD if 3.Nf3 is played because the lines where I feel Black has minimal winning chances are those where White exchanges and plays Nge2.

5) King's Indian Defense - My baby!  Give me this opening any time, any day, with either color, and I'm happy.  Same thing goes for the French Defense.

6) Grunfeld Defense - Sound, but I personally dispise it, especially the Black side.

7) Modern Benoni - Probably the most risky, and another that I can't stand as Black, and likely to play an Anti-Benoni these days with White when I do play 1.d4, even though right now, I'm mostly playing 1.e4 with an occasional shot at 1.c4 or 1.d4.

So no, 1.d4 is NOT "+-".  Try again.  NEXT?

i think i like the risk of benonis , white wants a positional game with 1 d4 , granted its got fireworks but its quieter to get going no?

with 1 c5 black goes no mate no slowwly slowly catchy monkey , and i guess thats why i like it

If white plays correctly black has no chance of winning against 1.d4. Of course weak players will make mistakes though. 1.d4 is simply better than 1.e4 you can face it or deny the truth it doesnt matter. Neither of the defences you listed above brings black equality, which is the point.
