Supi vs the Sicilian – Part 1 + PGN September 22, 2025

GM Supi Unleashes His Secret Weapon Against the Sicilian

Discover how Brazil’s creative genius transforms the most popular opening with one stunning setup

When GM Luis Paulo Supi commits to a new repertoire, one needs to pay attention. The Brazilian grandmaster, renowned for his deep positional understanding and creative approach, has just completed his most ambitious project yet: a comprehensive guide to dismantling the Sicilian Defense with moves your opponents have never seen.

The Problem Every 1.e4 Player Faces

The 2…d6 Sicilian complex presents White with an overwhelming choice. Do you prepare for the Najdorf? The Classical? The Dragon? Each system demands hundreds of hours of theoretical study, and even then, your opponents arrive armed with the latest computer analysis.

“So many things!” Supi exclaims in his introduction. “But here comes our first surprise: We don’t need to enter any of this anymore.”

The Revolutionary Approach: 4.Qxd4 and the Stunning 5.Qd3!

After the natural sequence 1.e4 c5 2.Nf3 d6 3.d4 cxd4 4.Qxd4 Nc6, most players expect the routine 5.Bb5 or the recently popular 5.Qe3. Instead, Supi delivers a theoretical thunderbolt: 5.Qd3!?

“BOOM! WOW! This is the thing. I just love this strange move,” Supi writes with characteristic enthusiasm. “I first saw it happening in front of me in a game of GM Richard Rapport, and then after analyzing it for quite some time, I start to understand that it is much more than just a surprise weapon.”
