King's Gambit, McDonnell Gambit
Chess opening
The McDonnell Gambit is a chess opening gambit in the King's Gambit, Classical Variation that begins with the moves:[2]
or alternatively via the Quaade Gambit:[3][4]
The opening is named after Alexander McDonnell, a 19th-century Irish chess master, who successfully introduced it in his third match with Louis-Charles Mahé de La Bourdonnais. The aim is to gain a significant lead in development (knight, bishop, and queen) for the sacrificed knight, followed by a kingside attack.
The McDonnell Gambit has always been much less popular for White than the similarly motivated Muzio Gambit (4.Bc4 g4 5.0-0). Although considered obsolete by MCO,[5] it has not been thoroughly tested.[2]
