Many chess players nowadays recommend the Rossolimo against c5-Nc6 Sicilian:
[fen ""] 1. e4 c5 2. Nf3 Nc6 3. Bb5
However, I find the open sicilian to be easier to play:
[fen ""] 1. e4 c5 2. Nf3 Nc6 3. d4 cxd4 4. Nxd4 Nf6 5. Nc3 e5 6. Ndb5 d6 7. Bg5 a6 8. Na3 b5 9. Nd5 Be7 10. Bxf6 Bxf6 11. c4 b4 12. Nc2 a5 13. g3 O-O 14. Bg2
One of the reasons of my preference is that I have control over the d5 square and black has a backward pawn on d6. Moreover, I can play moves like Qd3,a3, and play on the queenside with my rooks too.
My issue with the Rossolimo is that it gives up the bishop pair for no obvious outpost for the knight like the second position in the open sicilian that I shared above.
I would really appreciate it if you can tell me why the Rossolimo might offer better winning chances with White, and why top players are attracted to it, and why Black players try to avoid it in their repertoire. Also, if you can refer me to good thematic games with Rossolimo.
