  "description": "A White repertoire built around the Bishop's Opening (1.e4 e5 2.Bc4). Covers the structures a student needs to actually understand the opening: the classical ...Nf6 treatment and its Italian-style Nbd2-f1-g3 regrouping plan, the symmetrical ...Bc5 (with the sharp, named Moller Attack as a sideline), the simple refutation of the Calabrese Countergambit (2...f5), and a Vienna-style f4 plan against 2...Nc6. Every line and sideline stays within White's first 10 moves.",
