I play with White 1.d4 2.c4 3.Nc3 against many openings for Black including QGD, KID, Grunfeld, NimzoIndian defense, and Averbach variation in the Modern defense, etc. Recently, I have been facing this line in the Modern defense

[FEN ""]
1.d4 g6 2.c4 Bg7 3.Nc3 c5 4.d5 Bxc3 5.bxc3 f5!

I tried to look at the database and couldn't find something that I can understand to play against this line. I also tried to look at 4.Nf3 and I didn't like what I saw. Let me know what line do you prefer to play against such a line and the ideas behind it please.

Edit: I found one line that goes like

[FEN ""]
1.d4 g6 2.c4 Bg7 3.Nc3 c5 4.d5 Bxc3 5.bxc3 f5 6.e4! fxe4 7.f3! e5 

It's a crazy line and I believe that Black would be much more prepared than White on average in these positions.

    This is known as the Dzindzi Indian by the way. Named after GM Roman Dzindzichashvili. That might help your searches. May 11 at 0:11

    This isn't an answer to your question, but against the modern, 2. e4 is definitely a better try than c4. It has the added benefit that 3. Nc3 c5 5. dxc5 is a significant improvement for white over the Dzindzi. In fact, the Pterodactyl is nearly refuted with correct play. May 11 at 0:13
  • but I'm a d4 player, and many times the position transposes to a KID or Averbach. Thanks for the suggestion anws.

    First of all, the fact that Black exchanges this important dark-squared bishop for such cheap positional achievement has to be dubious. If I were white, I would not go out of my way to punish this or find a brilliant forced variation to refute something. Simply continue to develop, be ready to sac one of your c pawns, and rest assured that the dark squares weakness (esp. around king) will haunt Black. Or try the following move order: 1.d4 2.Nf3. Transposes to usual Q pawn openings while avoiding/preventing some options for black. For example, 1.d4 g6 2.Nf3 Bg6 3.c4 c5 4.d5; there,s no Bxc3. May 11 at 9:08

    @benham- this is actually a very strong line for black. It scores 56.7% for black. You're dismissing it without understanding it. The line you gave will likely transpose to a Benoni but by playing nf3 you've allowed black to avoid the Taimanov which is whites best lines vs the Benoni.
