Bishop's Opening: Calabrese Countergambit, Jaenisch Variation
Overview
Bishop's Opening: Calabrese Countergambit, Jaenisch Variation is a sacrificial opening line filed under ECO C23 in the Open Games group. The defining idea is the early concession of material to seize the initiative and unbalance the position.

Play reaches this position via 1. e4 e5 2. Bc4 f5 3. d3, after 5 plies of opening development.
