Default Dodging the Pterodactyl

Greetings.

As white, I open 1. c4 and I'm happy to play into a Marcozy Bind e.g.
1. c4 c5 2. Nf3 Nc6 3. d4 cd4 4. Nxd4 g6 5. e4 Bg7 6. Be3
and I also used to try to get into a Marcozy via
1. c4 c5 2. Nf3 g6 3. e4?! Bg7 4. d4 cd4?! 5. Nxd4 Nc6 6. Be3

But I'm now realising that if Black refrains from knight moves and
pawn captures, we reach what Keene called the Pterodactyl defence,
and that this seems to allow White no hope of any advantage:
1. c4 c5 2. Nf3 g6 3. e4?! Bg7 4. d4 Qa5+ 5. Nc3 d6 e.g.
6. Be2 Nc6 (or 6.. Bg4) 7. d5 Nd4 8. O-O Nxe2+ 9. Qxe2 Bg4
or 6. d5 Bxc3+ 7. bc3 Nf6 8. Nd2 Qxc3 9. Rb1 Nxe4

Nunn and Gallagher in "Beating the Sicilian 3" agree with this
when they say after 1. e4 c5 2. Nf3 g6: "The attempt to reach a
Marcozy Bind position by 3. c4 Bg7 4. d4 can be met by 4... Qa5+,
when it is not at all easy for White to maintain any advantage."

This leaves me with a gaping hole in my repertoire as White :-(
The critical position for me is 1. c4 c5 2. Nf3 g6 3. d4 Bg7 ...
Maybe 4. dc5!? Qa5+ 5. Bd2 Qxc5 6. Bc3 Nf6 7. e3
or 4. dc5!? Qc7 5. e4!? or 4. Nc3 d6 5. e3 ...
I don't know that these lines even have names, let alone books.
I'd like to avoid playing d5 and entering Benoni-land because
that's huge and I've never played it with either colour...

What's the best way to dodge a Pterodactyl ?

Regards, Peter Billam

In this position Khalifman recommends 6.Rb1!? (as played in Serper-Ruban,
Novosibirsk 1993, among others) as leading to an edge for White. See his
book "Opening for White according to Kramnik - 1.Nf3", part 3, chapter 7.
