1Nf3 can lead to many transpositions, a fact that may be challenging to both sides. I have been considering 1Nf3 from the Black side. My (current) repertoire is the Queen's Gambit Declined. Naturally, I considered QGD structures first. However, another approach is to be open to ECO D78-79 Gruenfeld-Slav positions.

After 1. Nf3 Nf6 2. g3 g6 3. Bg2 Bg7 4. O-O O-O, White can play 5d3. This can lead to reversed KID positions that I think are satisfactory for Black. Black may have other satisfactory approaches also.

White may do better with 5. d4 d5 6. c4 c6. This is a Gruenfeld/Slav. This position often arises from a KID or Gruenfeld, and is probably Black's most solid response to White's king side fianchetto in those openings.

Proceeding from a King's Indian move order, I've resisted this line as Black for psychological reasons. Sitting down and choosing the KID requires a fighting mindset. It is torally undermined by transposing to an exchange Slav.

However if one intends to play the QGD, the psychology is very different. The QGD is a solid line where Black obtains space and development, and enough imbalance to keep the game interesting. This description also applies to the D78-9 variations. I think the lines are doing well in theory and practice.

I agree this is a good mover order for Black, provided that he is set for 5d3 (... c5 6. Nbd2 Nc6 7. e4 O-O) which you mention.

It's been a while since I looked at the Nimzo-Larsen attack. It deserves a good look. I'll put it on my to-do list.

With this line the ancient game I readily think of is Portisch-Radulov 1978. (I think it was probably in Gligoric's "Game of the Month.") Last year Duda, against So, ran into the same thing Radulov did.

Good eye! 
1. Nf3 Nf6 2. c4 e6 3. g3 d5 4. Bg2 c5 5. O-O Nc6 6. d4 dc4 7. Qa4 Bd7 8. Qc4 cd4 9. Nd4 Rc8 10. Nc3 Nd4 11. Qd4 Bc5 12. Qh4 Bc6 13. Rd1 Qb6 14. Bc6 Rc6 15.Bh6
Radulov played 15...gxh6, while Duda played 15...Bf8, also to no avail.

I notice that So beat Duda 3 months earlier with colors reversed playing 8...b5.

My mistake. Not Krishnater, but Luis Rodi in The Modernized Queen's Gambit Decllined.

This has been advocated by Krishnater recently, and earlier by Kuljasevic. It looks very reasonable to me, but White scores well with the sharp 7Ne5 and 7Qa4, and the less interesting 7dxc.

The Tarrasch QGD is an option for Black. Instead he might choose a line in the Catalan. His choice depends on move order.

1. Nf3 d5 2. g3 e6 3. Bg2 Nf6 4. O-O Be7 5. c4 O-O 6. d4 dxc4 is a very main line in the Catalan.

This sequence allows the King's Indian Attack:  1. Nf3 d5 2. g3 e6 3. Bg2 Nf6 4. O-O Be7 5. d3 O-O 6. Nbd2 c5 7. e4 

Or

1. Nf3 d5 2. g3 c5 3. Bg2 Nc6 4. d4!? Nf6 5. O-O e6 6. c4 dc4

This has been advocated by Krishnater recently, and earlier by Kuljasevic. It looks very reasonable to me, but White scores well with the sharp 7Ne5 and 7Qa4, and the less interesting 7dxc.

With this move order, Black can aim for a reversed King's Indian:
1. Nf3 d5 2. g3 c5 3. Bg2 Nc6 4. O-O e5

"1.c4 e6 2.Nf3 d5 3.b3 Nf6 (being careful) 4.g3 Be7 5.Bg2 O-O 6.O-O c5 7.Bb2 Nc6 8.e3!? b6 9.Nc3 Bb7 ...  9...dxc4!"

There is also 8...d4 as presented in Dangerous Weapons:  Flank Openings. After 9. ed4 cd4 10. Re1, both 10...Re8 and 10...Ne8 have been played. I'm generally suspicious of reversed Benoni lines for Black as I respect the Benoni itself. However Black normally does not play ...b6 ...Bb7. So I wonder if the moves b3 Bb2 help Black even though he loses a tempo with ...e6 ...e5.

So against 1.e4 are you thinking French or Sicilian? 

If you don't mind a French then 1.Nf3 d5 2.g3 Nf6 3.Bg2 e6 4.O-O Be7 is a bullet-proof Reti move order. White might play 5.d3, then if you play like Uhlmann you will win, only if white plays like Fischer would you lose. Or white might play 5.c4 and/or 5.d4 when a Tarrasch is on the menu.

Against the English you have 1.c4 e6 next 2...d5 and white will have to commit something. 

For a Tarrasch player there are only two concerning move orders (from distant memory):

1.Nf3 d5 2.b3!? c5 (2...Nf6 is safer) 3.e3 Nc6 4.Bb2 Nf6 5.Bb5 something with c4, cxd5, d4 and black winds up a tempo down on some Normal Variation, but as you can tell I don't remember the details. That was in Keene (1977) Nimzo-Larsen Attack, from when he was still writing good books. I last looked at those notes 30 years ago, the theory was old then and probably hasn't changed much since.

1.c4 e6 2.Nf3 d5 3.b3 Nf6 (being careful) 4.g3 Be7 5.Bg2 O-O 6.O-O c5 7.Bb2 Nc6 8.e3!? b6 9.Nc3 as recommended in Soltis (1990) Winning with 1.c4. It's a little poisonous, after losing here once with 9...Bb7 I used Keene's Flank Openings to prepare the sharp 9...dxc4! as played by Spassky and Timman.

If you look at Kasparov's games against transpositional move orders he always developed the kingside first. Of course the most modern trend (e.g. Dubov) they can't do that, but for the main line Rubinstein it's still sounder.

I've been considering responses to the Reti. Slav type responses have been recommended and are ok. However, as I don't play the Slav, it's not my first choice. You mention several interesting possibilities, including that shown in the game Duda-Korchnoi.

1. Nf3 Nf6 2. g3 c5 3. Bg2 Nc6 4. O-O e5 5. d3 d5 6. e4 d4 7. Nbd2 Bg4 8. h3 Bh5 9. g4 Bg6 

* * * * * * * *
* * * * * * * *
* * * * * * * *
* * * * * * * *
* * * * * * * *
* * * * * * * *
* * * * * * * *
* * * * * * * *
*

In addition to 10. Nh4 Nd7 11. Nf5 h5 as played, there is 10. Nxe5 Nxe5 11. f4.

There are many move orders possible. The game could commence 1. Nf3 d5 2. g3 c5 3. Bg2 Nc6 4.0-0 e5, etc. However, White might play 4.d4 instead. This is a reversed Gruenfeld Indian defense if Black plays 4...cxd4, and I think that is hard for Black.

Instead, I would choose 4... Nf6 5. O-O e6 6. c4 Be7.

* * * * * * * *
* * * * * * * *
* * * * * * * *
* * * * * * * *
* * * * * * * *

This easily leads to the Tarrasch Defense of the Queen's Gambit Declined:  7. cd5 ed5 8. Nc3 O-O

* * * * * * * *

* * * * * * * *
* * * * * * * *
* * * * * * * *
* * * * * * * *
* * * * * * * *
* * * * * * * *
*

Either player can avoid the Tarrasch. For example, 7. dc5 Bc5 8. a3 O-O 9. b4 Bb6 10. Bb2 Qe7 11. Qc2 Rd8 12. e3 e5 13. Nbd2 reaches the following position from the game Schandorff-Aagaard 2011.

This is game 22 in Sam Collins' book The Tarrasch:  Move by Move.

Question re: reversed classical KID per Ganguly

I see that in a new Chessable course (Lifetime Repertoires: Sidelines and Flank Openings for Black), Surya Ganguly goes for a reversed Exchange: 1. Nf3 Nf6 2. g3 c5 3. Bg2 Nc6 4. 0-0 e5 5. d3 d5 6. e4 de4 7. de4 Qxd1 8. Rxd1 Bg4. He notes that he is eschewing the engine-preferred 6...d4 (as well as the second choice of 6...Be7), and comments about avoiding going into a main line a tempo down. This makes me curious as to what he advocates against 6. Nbd2. (Also, does he still go for some kind of reversed Exchange against 6. Na3?)

By the way, re 6...d4, an ancient bit of theory is comparable to an old main line of the Petrosian: 7. Nbd2 Bg4 8. h3 Bh5 9. g4 Bg6 10. Nh4 Nd7 11. Nf5 h5 (Doda-Korchnoi, Leningrad 1967), unclear according to Uhlmann.
