French and King's Indian structures: where to strike
Nimzowitsch's rule: attack the base of the chain, not the tip. Knock the foundation out and the whole thing falls.
Hit the base of the chain with the c-pawn.
Sicilian. The proper response. Sharp.
3 more clean runs (at any point) to reach Recall.
French Advance. The chain runs d4 (base) to e5 (tip). Strike the base.
3 more clean runs (at any point) to reach Recall.
