The Sicilian Rossolimo is used to avoid the big theory of the Open Sicilian but is itself quite a labyrinth of theory

Selected games

Rozentalis-Heinemann

SI Rossolimo 3.Bb5+ Nd7 4.Ba4

Bundesliga 2018-19 rd3

The 4.Ba4 approach is quite popular now. The structure after 11..d5 12.e5 gave Black problems. The Bg7 was passive and there was no good plan to get active play

After 21..Qc8(Diagram)

Black has a loose kingside and is overall quite passive. The kingside is devoid of defenders while White has a menacing buildup with a crisis brewing on g6 already

What do you recommend for White?
