1.e4 c5 2.Nf3 Nc6 – Top-Level Repertoire for Black + PGN February 16, 2026

1.e4 c5 2.Nf3 Nc6 – Top-Level Repertoire for Black by GM Brandon Jacobson

The Elite Choice: When Flexibility Becomes a Weapon

Magnus Carlsen, Nihal Sarin, Hikaru Nakamura—when top players need a Sicilian that combines solidity with dynamic potential, they turn to 2…Nc6. This seemingly simple move order has quietly become one of the most sophisticated weapons in modern tournament practice, offering Black the strategic flexibility of the Sveshnikov. GM Brandon Jacobson’s new course builds a complete repertoire around this pragmatic yet ambitious approach, showing how 2…Nc6 serves as the gateway to dynamic play in both the Open Sicilian and the Rossolimo.

The brilliance of 2…Nc6 lies in what it avoids. By delaying …e6 or …d6, Black retains maximum flexibility while steering the game toward the Sveshnikov and Rossolimo structures—two systems that have proven their worth at the highest level. Jacobson constructs the repertoire around Sarin’s favorite continuation 3.Bb5 Nf6, a line that has also appeared regularly in Carlsen’s and Nakamura’s games. Against the Open Sicilian, the course advocates the continuation with 7…a6 8.Na3 b5, which deviates from the older 8…Be6 variation in favor of fresh practical solutions. Notably, after 7.Nd5 Nxd5 8.exd5 Ne7, the repertoire embraces the flexible 9.c4 Ng6, avoiding the theoretical labyrinth of 8…Nb8 while maintaining full dynamic compensation for the structural concessions.
