The alternative is 9. Qe2.
9...Ba5 10. Qe2

10...cxd4
In the game Sarthou, G. - Adams, M., Moscow 2001 Black played 10...a6 11. a4 b6 12. Rd1 Bb7 13. d5 exd5 14. Nxd5 Nxd5 15. Bxd5 Bxd5 16. Rxd5 Qc7 with equality.
11. exd4 Bxc3 12. bxc3 Qc7 13. Bd3 b6
If 13...Qxc3 then 14. Bd2 or 14. Bg5 and White has development advantage.
14. c4 Bb7 15. Re1 Rac8 16. Bg5 h6 17. Bd2 Rfd8 18. Rac1 Qd6 19. Bb4 Qf4 20. Qe3 Nh5 21. Nd2?!
Correct is 21. Be2 with more or less equal game.
21...Ndf6 22. Bc3

Thunderbolt! A great sacrifice leads to a big advantage in all variations.
