King's Indian Attack: Yugoslav Variation

Lately, I have ran into a few players who blitz out the moves 1.Nf3 2.g3 3. Bg2 4.O-O and I feel that I should "prepare" my response in advance (as a repertoire choice). As of now I have no systematic response to this opening (when I am Black), but my "natural" moves usually end up in this position: 

1.Nf3 d5 2.g3 Nf6 3.Bg2 c6 4.O-O Bg4 (Reti) King's Indian Attack: Yugoslav Variation.

I usually play this, but I am not really attached to this opening; I then checked the opening explorer, and Black does not score too well. Opening statistics should not be taken blindly, but I was wondering if anyone has a better recommended response (or if this opening is all right for Black). I realize that there are many ways to play this setup and how much play could vary even after 4...Bg4 in the Yugoslav -

what might be better recommended against this King's Indian Attack setup? Should I adopt a different opening, or learn this setup better?

(This is the forum to be directed towards: feel free to post  )

it depends on your way to play against 1.d4.

For example if u play dutch, 1.Nf3 f5 can be your move.

If u play KID, Nf6-g6.

If u play QGD, then e6-d5.

If u like London system variation as white, then d5-Bf5 at some point.

Etc...

There are many good set up, but u have to be more precise about you.

IM poucin, 

thank you for your insight; this is precisely what I was curious about. Personally, against 1.d4 I play QGD or Slav lines usually, but will sometimes play the Indian games via 1...Nf6

Clearly, the Yugoslav Variation here might transpose (as d5 has been played where e6 may follow shortly after) - personally, do you feel that the Bishop move to g4 is even worth the trouble? I am considering dropping this potential pin (perhaps later on White's Queen from g4) altogether and just playing e6 and d5 as you recommended in your QGD idea.

I thought 1. Nf3 f5 2. d3 Nf6 3. e4 was considered to be so strong that 1. Nf3 f5 was practically extinct.

If you typically play the Orthodox against 1. d4, then why not play it against 1. Nf3?

1.Nf3 f5 has been rehabilitated, especially thanks to dutch GMs!

For a while, 1.Nf3 f5 2.e4 was considered a refutation, then 1.Nf3 f5 2.d3 followed by e4 (a refinement) with an impressive victory by a young norvegian named Carlsen against Dolmatov if i remember well.

But black is ok now.

There is many systems available to counter 1.Nf3-2.g3.

Almost everybody is ok if u develop well and if u know what u are doing.

d5-e6 => QGD position

d5-Bf5 => London system positions

d5-Bg4 => Torre attack position

The former two being similar to slav position, with same structure : usually we play c6 before moving the bishop c8.

There is nothing wrong with Bg4 : online databases are not trustworthy and stats in general are not enough to evaluate something.

Moreover, explorer on chess.com is a bad device.

For example, according my megadatabase 2017, after 1.Nf3 d5 2.g3 c6 3.Bg2, the move played the most, and having the best stats, is Bg4...

 The surprise for Black in the ...Bg4 or ...Bf5 lines are that he might not play against the KIA at the end.

White's after castle has the option to play d3 followed by c4 and transpose to Reti or even push d4 ( nowdays has become popular ). The flexibility in Whites approach makes this system difficult to prepare against. 

I think a universal system against 1.Nf3 is the one that prepares e5 with d5-Nc6-Bd6. If Black can play e5 before White consolidates his center then almost always is doing fine. 

Black has to avoid himself from the mind trick to become optimistic. That's the worst enemy against White's formation.

d5-Nc6 is fine if u play Chigorin defence against 1.d4...

Very insightful I might consider playing this

Thanks
