I am referring to main lines where the pawn sacrifice is accepted.
Most reference books will give the main line as
1. e4 c5 2. d4 cxd4 3. c3 dxc3 4. Nxc3 Nc6 5.Bc4 e6 6.Nf3 d6 7.0-0 Nf6 8.Qe2 0-0 9.Rd1 e5
Followed by either 10.Be3, 10.h3, 10.Bg5, 10.a3 or even 10.b4.
They usually evaluate this 'main line' as a dynamic equality.
Repertoire books often offer other ideas for Black (with...g6, or ...Ne7, or ...Bb4, or ...a6 and ...b5, or 3..e5 or refusing the gambit right away).
