The Grünfeld Defense offers Black unparalleled counterplay and winning chances against 1.d4. Yet even experienced players hesitate to adopt it, intimidated by the theoretical jungle that surrounds this razor-sharp opening.
"The Grünfeld always fascinated me, but I was often scared by all the theory," admits GM Baadur Jobava. "Now things are easier with engines, so I asked two dynamic players, IM Dragos Ceres and GM Luca Moroni, to help me build something fresh, fun, and easy to use."

In the pursuit of opening advantage, most players chase computer evaluations and memorize endless theoretical lines. GM Swapnil Dhopade takes a different approach—one rooted in practical understanding and over-the-board pressure.
This course introduces a sophisticated hybrid system against the Queen's Gambit Declined that bypasses Black's most prepared defenses while maintaining genuine winning chances. Rather than entering well-trodden theoretical paths, Dhopade presents a refined move order: 4.Nc3 followed by 5.g3—a subtle Catalan transposition that avoids Black's sharpest resources.

We are thrilled to present Chigorin Defense According to Jobava – the latest addition to our Legendary Openings series. In this fascinating course, GM Baadur Jobava breathes new life into the once-dismissed Chigorin Defense, offering a full, aggressive repertoire for Black after 1.d4 d5 2.c4 Nc6.
For years, the Chigorin was viewed as an offbeat, borderline-dubious choice—an opening where Black voluntarily breaks traditional positional rules. But the times have changed. With the help of modern engines and creative minds like GM Jobava’s, old evaluations are being overturned.

This isn't about playing for equality—it's about reaching excellent positions through superior understanding rather than superior memory.
