Play the Open Sicilian – 1.e4 c5 2.Nf3 d6 3.d4 for White + PGN September 12, 2025

The Open Sicilian remains one of the most theoretically demanding openings in competitive chess. GM Kalyan’s latest course provides a structured approach to handling the main Sicilian systems that strong players encounter regularly: the Najdorf, Dragon, Scheveningen, and key sidelines.

“The Najdorf is probably the single most popular chess opening at all levels,” notes GM Kalyan in his introduction. “Moreover, players who play the Najdorf tend to be lifelong Najdorf players. The theory is constantly evolving, and Black has a lot of workload to keep themselves updated.”
