If 1. c4, then is it best for Grünfeld players to continue into the Anti-Grünfeld line with 1. c4 Nf6 2. g3 g6 3. Nc3 d5 or play something else, and what else would it be? If Symmetrical, then what if White forces the Maróczy Bind?
The Symmetrical is obviously very strong and white cannot force the Maroczy:
E.g. 1. c4 c5 2. Nc3 Nc6 3. Nf3 and now
A) In 3...Nf6 4. d4 cxd4 5. Nxd4 black still has 5... e6 or Qb6
B) even 3... g6 4. d4 cxd4 5. Nxd4 Bg7 6. Nc2 can only end up being the Nc2 version of the Maroczy.
C) 3... Nd4 is not the Maroczy, although there could be a repetition of moves with a second chance to go into it...
D) 3... e5 totally avoids any Maroczy.
And 1. c4 c5 2. Nf3 Nc6 3. d4 cxd4 4. Nxd4 can be played with 4...Nf6 5. Nc3 e6 or 4...e6 or 4...Qb6.
Of course allowing the Maroczy transposition is an option for black (it's nice and solid, after all), although white will even often not go into it and instead play some purely English lines.
