Deep Preparation – Sicilian Four Knights with …Bc5 + PGN October 25, 2025

Beyond 6…Bc5: Dreev and Basso’s Ambitious Four Knights Blueprint

In 2019, two grandmasters quietly planted a theoretical seed that would reshape the Four Knights Sicilian landscape. GM Pier Luigi Basso became the first to demonstrate 12…Ne7—a paradoxical knight retreat that transforms a cramped position into dynamic counterplay, and GM Alexey Dreev soon followed. What began as an experiment in uncharted territory has now exploded in popularity, aided by modern engine analysis that validated their human intuition. This course reveals the full architecture of that breakthrough.

From Solid to Ambitious: The Evolution of Dreev’s Four Knights Repertoire

Dreev and Basso previously collaborated on Four Knights Sicilian for Black, recommending the solid 6…Bb4. That course delivered reliability—a solid weapon for Black. Deep Preparation – Sicilian Four Knights with …Bc5 marks a philosophical departure. Here, 6…Bc5 embraces ambition: Black plays for three results, accepting sharper positions in exchange for genuine winning chances. The critical position after 1.e4 c5 2.Nf3 e6 3.d4 cxd4 4.Nxd4 Nf6 5.Nc3 Nc6 6.Ndb5 Bc5 7.Bf4 O-O 8.Bc7 Qe7 9.Bd6 Bxd6 10.Qxd6 Qd8 11.O-O-O a6 12.Nd4 Ne7 demands precision from both sides. White’s space advantage collides with Black’s dynamic piece coordination—the kind of tension where deep preparation separates theory from understanding.
