Ruy Lopez Chigorin
Black's complete repertoire in the Ruy Lopez Chigorin Variation (9...Na5 10.Bc2 c5 11.d4 Qc7). Ten drills cover the classical 12.Nbd2 cxd4, the old 13.d5 main line, the Karpov 12.d5 fianchetto plan, Yates' 12.a4, Smyslov's ...Bd7, Keres' ...Re8, Bondarevsky's 11...Nd7, the closed 12.d5 c4, Petrosian's ...Bb7 with ...Nc4, and the quiet 12.b3 setup.
The Chigorin Variation (9...Na5 10.Bc2 c5) is the historical mainline of the Closed Ruy Lopez — it dominated top-level play for over a century and remains the most principled answer to Bb3. The plan is direct: kick the bishop with ...Na5, strike the centre with ...c5, and prepare deep middlegame plans with ...Qc7. This pack drills every modern White try: the classical 12.Nbd2 cxd4 and the old 13.d5 Nd8 regroupings, Karpov's 12.d5 fianchetto plan, Yates' 12.a4 flank, Smyslov's flexible ...Bd7, Keres' patient ...Re8, Bondarevsky's 11...Nd7, the closed 12.d5 c4 clamp, Petrosian's ...Bb7 with the tactical ...Nc4 break, and the quiet 12.b3 setup. Forty exam positions sharpen the critical knight tours and pawn breaks so you reach a rich Chigorin middlegame fully prepared.
