The McDonnell Gambit is a chess opening gambit in the King's Gambit, Classical Variation that begins with the moves:[2]
1. e4 e5
2. f4 exf4
3. Nf3 g5
4. Bc4 g4
5. Nc3
or alternatively via the Quaade Gambit:[3] [4]
4. Nc3 g4
5. Bc4 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 (knight, bishop, and queen) for the sacrificed knight, followed by a 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.
After 5... gxf3 6. Qxf3 is usual, though the wild 6.0-0 is occasionally seen. Now 6...Bh6 (as in the McDonnell–La Bourdonnais game below) is regarded as inferior. Better options for Black are:
1. e4 e5 2. f4 exf4 3. Nf3 g5 4. Bc4 g4 5. Nc3 gxf3 6. Qxf3 Bh6 7. d4 Nc6 8. 0-0
Continuing his policy of development over .
8... Nxd4 9. Bxf7+!
A frequently seen move in the King's Gambit as it strips away a key defensive pawn.
9... Kxf7 10. Qh5+ Kg7 11. Bxf4 Bxf4 12. Rxf4 Nf6 13. Qg5+ Kf7 14. Raf1
McDonnell has built up a winning attack almost effortlessly.
14... Ke8 15. Rxf6 Qe7
Looking for some with his queen and at the same time freeing a square for his king.
16. Nd5! Qc5
One last try; if McDonnell is inattentive he could miss the 17...Nf3+! followed by 18...Nxg5 when suddenly he has a lost position.
17. Kh1! Ne6
18. Rxe6+! dxe6 19. Nf6+!White will win the queen next move, so La Bourdonnais resigned here.
