Overview

Bishop's Opening: McDonnell Gambit, La Bourdonnais-Denker Gambit 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 Bc5 3. b4 Bxb4 4. c3, after 7 plies of opening development.
