Hi Kushal, could you please post your question re opening repertoire in the Pro Members' Chanel. That is where the CM-Teams replies. PS. I face this 2nd Nf3 quite often, too. I usually replay 2. ... d5 but this leads to positions quite different from the typical CM-lines.

Sorry, I thought you meant 2. Nc3 to prepare for 3rd e2-e4

Hi Kushal, 
A good way to play and reach chessmood openings would be 2.Nf3 g6. If W plays 3.c4 you can reply 3...c5, if 3.g3 c5, 4.c3 b6 and if 3.Bf4 Bg7, 4.e3 d6.
I used to play 2.Sf3 c5, which I also liked and I think GM Avetik likes that also as an alternative, if your rating is not too high (below 1800 or so)

if we play 2.g6 there is nbd2 or g3 many sidelines which we see often in our games . i dont say the lines are good but there is a need to be studied .  we get new pawn structures and ideas which we should be aware of and if 2.g6 there is bg5 which converts to kings indian side lines which i am not aware of.
2.c5 is good option i think because it removes huge part of unnecessary part which we have to learn if we 2.g6

Against 1. d4 Nf6 2. Nf3 I usually play 2. ... d5, as apart from the chessmood openings I play semi Tarrasch defence, but if you are unsure about theory, and do not have positional patience, play the same way against the London system with double fianchetto and opening up the centre after O-O.

After 1.d4 Nf6 2.Nf3 I like 2..c5. It also fits in the Benko-repertoire.

Here some illustrative variations:

(a) 3.d5. After this move you can play (1) 3..b5, or (2) 3..e6 with the idea 4.c4 b5 (Blumenfeld Gambit; note this can also arise after 1.d4 Nf6 2.c4 c5 3.d5 b5 4.Nf3 e6!?)

(b) 3.c4 (this can also arise after 1.d4 Nf6 2.c4 c5 3.Nf3) 3..cxd4 4.Nxd4 e5 5.Nb5 d5 6.cxd5 Bc5, a very interesting gambit

2...c5 has one minor risk, which is 3. Nc3, an attempt to transpose back into Avrukh 2B territory (Ch9~13). In contrast, 2...g6 is a more secure way to remain within CM repertoire. However, in my personal experience, this is a very successful choice in faster time controls when people neglect move order nuances.

3.Nc3? are you sure this is a good (even less, playable) move? I think we just play 3...cxd4 4. Nxd4 Nc6 and if 5.e4 then we play 5...g6 and we are in accelerated dragon, even dodging the critical Maroczy Bind.

My bad. I meant after 3. d5 e6 4. Nc3. Thanks for pointing it out on time.

I know of this 3.d5 e6 4.Nc3, and I understand that after 4..exd5 5.Nxd5 Nxd5 6.Qxd5 you may not like the hole on d5, but it does not seem to be too bad after for instance 6..Nc6 7.e4 Be7 8.Bc4 0-0 9.0-0 d6 10.Rd1 Be6 11.Qd3 Bxc4 12.Qxc4 Qb6. I know, this is not a forcing line, but just an example line.

Show me what line you are exactly afraid of, and I'll try to convince you otherwise. ;)

Side note: 4..b5!?/?! is also interesting (but maybe dubious). White can go wrong here in many ways. The best for White seems to be 5.dxe6 fxe6 6.Nxb5 d5. But it is Benko-like.
