Black has a few ambitious options though, including the} Nf6 8. 0-0-0 Ne5 9. Qg3 b5 10. f4 Neg4 11. Bg1 h5 $13 {of Karjakin,S-Caruana,F London 2017} )(7. Qd2 {is the only move I've annotated a game in before: see Radjabov-Rapport, Tata Steel 2019 for 7...b5, Carlsen-Matlakov, Tata Steel 2018 for 7..Nf6 8.f4, or Das-Adhiban, Reykjavik 2018 for 7...Nf6 8.0-0-0. Having looked at the line fairly extensively I think 7...b5 is very playable.} )(7. Bd3 Nf6 8. 0-0 {Now Black has a move which is both principled (exploiting the placement of White's light-squared bishop) and cynical (somewhat simplistic for a Sicilian.)} Nxd4 $5 {(There is also ...Ne5, as you would expect.)} 9.

Nxd5 cxd5 {We have now a position that does not inspire great confidence, but in fact to prevent Black's game from becoming freed White must swap both dark-squared bishops and queens, leading to a more or less equal endgame, as in the 3.Nc3 Nf6 4.e5 French.} )9.
