Sicilian Defense: Rossolimo Attack

Main Line

1. e4 c5 2. Nf3 Nc6 3. Bb5

Overview

One of the most popular anti-Sicilians at the elite level. With 3.Bb5, White pins the c6-knight and threatens Bxc6, doubling Black's pawns and steering the game into a positional middlegame on White's terms. Sidesteps the massive theory of Open Sicilians (Najdorf, Dragon, Sveshnikov) and reaches an early middlegame by move 8. Named after Nicolas Rossolimo, a Greek-French-American grandmaster who pioneered the line in the 1940s and 1950s. Now the highest-ROI Anti-Sicilian in 2026 — played at the elite level by Magnus Carlsen, Hikaru Nakamura, Vladimir Kramnik, and Wesley So as a regular weapon, not a surprise.
