People often play:

  1. d4 Nf6 2. c4 e6 3. Nf3 b6 4. g3

And allow both the Queen's Indian Defense:

4... Ba6 OR 4... Bb7

And the Catalan:

4... d5 5. Bg2

Why not play:

  1. g3

and transpose into Catalan, instead of learning theory of both the Catalan and Queen's Indian Defense?

White can't force black to go for a setup with ...d5, so it's not a given that 3.g3 will end up in the Catalan.

In particular there is 3...c5, trying to transpose to a Benoni where the g3 variations aren't the ones with the most dangerous reputation.

The issue is in committing to 3.g3 a move earlier. Then if Black plays 3...d5, White must play the Catalan (with 3.Nf3, he still had the option to play a different line in the Queen's Gambit). Or take 3...c5 - against 3.Nf3, White has some edge in a few different lines. But against 3.g3 Black should be pretty close to equal, since as @RemcoGerlich mentioned, the Fianchetto variation isn't White's best try against the Benoni.

Of course, some people still play 3.g3 anyway, since they're fine playing with a fianchetto in all these lines. I think it's what Avrukh recommends in his books. It's just not everyone's cup of tea.

  • I am wondering this: Why do people play 4. g3 in Queen's Indian, when it can transpose to Catalan ??

    @Feliks_WR Black has committed to playing 3...b6 there. He may be able to push ...d5 and transpose to a Catalan at some point, but even still Black only has ...b6 Catalan setups at his disposal. There's also the fact that 3...b6 rules out the modern benoni option. Jun 15 at 10:42

  1. The QID isnt really anything to worry about. Most white players are more worried about the NID or the KID and are probably happy to see a QID. White scores 54% and SF gives .37 to white so white is able to maintain an advantage

  2. The Catalan doesn't really score better and is only .11 according to SF. I don't really see the point of learning an entire new opening if it doesn't give better results.

  3. Transpositions- I don't play these openings but I'm sure there are some tricky transpositions.

So, you're saying you should learn the queens gambit AND the Catalan and then learn all the transpositions and sidelines etc. What are you gaining by doing that? It just seems like a lot of extra work for no reason to me.

  • Ususally, engine analyses are taken with a grain of salt (given the absence of tactics).

  • Also, I play the black side, & I wondered why white played 4. g3 instead of 3. g3

  • I agree that engines can be weak in the opening but I'm trying to give something objective to back up what I say. Theres not any evidence to the contrary so....

  • Again, I dont play these lines but I think Nf3 is a waiting move. 3. g3 is more committal.
