Queen’s Indian for Black — A Top-Level Repertoire by GM Jose Martinez Alcantara and GM Pier Luigi Basso

In 1931, Max Euwe and José Raúl Capablanca reached a position where Black had just sacrificed the exchange on a8. Capablanca, with the black pieces, stood better — and never realised it, repeating moves into a draw he should have been pressing to win.

Nearly a century later, that same position is the critical theoretical battleground of this repertoire. White’s most testing engine moves still lead straight back to it, and Black is still playing for three results. That is the spirit of the whole course: principled, fighting, and built on lines that reward the player who understands them.

A practical repertoire with a familiar DNA

GM Jose Martinez Alcantara (Jospem) and GM Pier Luigi Basso set out to give Black an ambitious answer to 1.d4 — one that fights for the full point without memorising endless forcing theory.

The recurring idea is the early 5…Bb4+, chosen over the mainstream 5…Be7, followed by the clean 6.Bd2 Bxd2+. No 6…Qe7, no 6…c5, no 6…a5: Black simply trades and heads for clear, fighting middlegames. Against the Petrosian set-up with 4.a3, the authors recommend the energetic 5…Ne4! rather than the routine 5…d5, again steering the game toward three results.

The emphasis throughout is on understanding the type of position rather than recalling concrete moves. In the 8.0-0 lines the battle reduces to a single positional question — can White ever achieve e4, and is Black in time for …Ne4? — and the authors explain those nuances in full instead of dumping variations.
