King’s Indian Defense – Repertoire for Black – Part 4 + PGN June 28, 2026

The King’s Indian Defense for Black – Part 4: The 7…Na6 System

“A knight on the rim is dim.” Few maxims are drilled into beginners more often — and few are refuted more elegantly than by 7…Na6 in the Classical King’s Indian. The knight steps to the edge not to linger there, but to spring into c5, where it pressures e4 while Black’s central counterplay gathers force.

That paradox runs through the whole of Part 4. Instead of the dense, move-for-move theory demanded by 7…Nc6 or 7…Nbd7, Black gets a repertoire organized around recurring ideas: the …Na6–c5 route, the flexible …Qe7, reinforcing e5 while keeping all options open, and the thematic …Ng4 and …f5 breaks. The same plans reappear against almost everything White tries, so understanding carries the load rather than memorization.

What makes this course different

The system is built for players who want to fight for the full point with Black. Every line keeps the position rich and double-edged, with clear plans for both wings rather than a forced march toward equality. Even the variations with the dullest reputation get rehabilitated here — Black scores excellently in the Exchange lines, and GM Baadur Jobava’s treatment of the 7.dxe5 Exchange Variation is likely to change how you view a structure most players reach for only to make a draw.

The authors and their reasoning

GM Andrea Stella supplies the theoretical foundation — the move-order subtleties, the critical 9.d5 main line, and the engine-approved resources behind each branch — while GM Baadur Jobava brings the creative, practical edge the King’s Indian has always rewarded. Their case for 7…Na6 is straightforward: it is sound, flexible, and low-maintenance, yet it has been trusted at the very top by players such as Firouzja and Grischuk. That blend of objective health and fighting character is exactly what a winning weapon for Black should offer.
