The Roadmap of Variations

Jobava London (1.d4 d5 2.Nc3 Nf6 3.Bf4)

3…a6 → Pultinevicius
3…c5 → Fier & Gumularz (with different continuations)
3…Nh5 → Gavrilescu (surprising, played by top GMs like Carlsen & Caruana)
3…Bd7 → Kazakouski (rare but very tricky)
3…h6 → Dardha & Blohberger (a hot and practical approach)
3…b5 → also part of Pultinevicius’ repertoire

Classical London (1.d4 d5 2.Nf3 Nf6 3.Bf4)

3…c5 → Gumularz and others, going for active counterplay
3…Nh5 → Gavrilescu (inspired by his Jobava choice)
3…Bf5 → Blohberger & Kazakouski (solid but far from dull)
3…e6 followed by …Qb6 systems → Gumularz & Fier with different nuances
3…c5 followed by …Qb6 → Pultinevicius (principled continuation)
3…Nh5 at a later stage → Dardha’s ambitious solution

Every line is explained in depth by the respective grandmaster, focusing on practicality, ambition, and ease of learning.
