  "description": "A Black repertoire against 1.e4, built around the Caro-Kann Defence (1.e4 c6 2.d4 d5). Covers the structures a student needs to actually understand the opening from Black's side: escaping the light-squared bishop to f5 against the Advance Variation (and the common Bd3 trade), the famous Classical Main Line with the Bf5-g6-h7 retreat against 3.Nc3/3.Nd2, and how to meet the Exchange Variation and the sharper Panov-Botvinnik Attack (4.c4). Every line and sideline stays within White's first 10 moves. This is a new, standalone teaching pack, separate from the deeper personal repertoire already seeded in this app.",
