Opening Specialists

Who are the leading experts on openings such as Nimzo Indian, Slav defense, Semi-Slav defense, Sicilian-Taimanov, etc?  It would be nice to know as it would help me in my study of master games.

Look at who plays those opening frequently. If someone responds with the Slav in 80% of their games against 1. d4, and they're a GM, you can be sure they're a leading expert -- regardless of if they write on it or not.

Nimzo - Kramnik, Karpov's old games

Slav and Semi-Slav - Shirov, Anand

Sicilian Taimanov - Mamedyarov, Movsesian
