A super-GM repertoire

From my research the English opening (1.c4!) seems a good
first move in top level chess. Although the fundamental differences
between various opening moves are small (*), and a good GM
obviously also tries to look at what the opponent usually plays,
or knows (repertoire). Yet fundamentally, it also matters to know
how theory  develops, for example:

1.c4 e5 (1...c6 leads to Slav2. Nc3 Nf6 3. g3! Bb4! (3...Bc5
4.Nf3! e4 5.Nd4 0-0 6.Bg2 Bxc3 7.dxc3 d6 8.0-0 Re8 9.Nc2
and White maintains a slight advantage.

Otherwise, after 1. c4  Nf6  2. d4 e6 (2...g6 leads to Gruenfeld
or Kings-Indian) 3. Nc3    (g3 also is possible) Bb4!  4. Qc2!  0-0
(5. e4!?   d5   6. e5   Ne4  7. Bd3  c5 8. Nf3  cxd4  9. Nxd4 Nd7
10. Bf4   Ndc5 11. 0-0  Nxd3=) 5.Nf3! d5 (c5 6.dxc5 Na6 7.g3!
Nxc5 8,Bg2 b6 [...Nce4 9. 0-0 Nxc3 10. bxc3  Be7 11. e4  d6
12. e5  dxe5 13. Nxe5 Qc7 14. Qe2  Bd6 15. Re1 Bd7 16.Bg5!N]
9.0-0 Bxc3  10.Qxc3 Bb7 11.Rd1! Qe7 12.Qa3! +/=) 6.a3 Bxc3
7.Qxc3 dxc4
