Ne7 in the actual game to avoid weakening the e6 pawn.

Master Strategy: Black questions the pinning bishop with 9... h6, forcing White to clarify diagonal intentions before committing to central action.

Black has eradicated White's spatial wedge, activated the dark-squared bishop, and eliminated all structural cramping. This proves why striking at the base of the pawn chain with ...c5 is the canonical master defense against an advanced pawn wedge, rather than the slow flank pawn pushes seen in the actual game.

Alternative Path Available — Consider: Resilient Defense: Bishop Retreat with 28... Be7!
