Starting position of the Allgaier gambit after 5. Nf3 – g5

The Allgaier Gambit is an opening variant in chess . In the system of ECO codes , the Gambit is classified under the key C39. It is named after the chess master Johann Allgaier , who published an analysis of the gambit in 1819 .

The Allgaier Gambit results from the King Jumper Gambit after the moves:

1. e2 – e4 e7 – e5
2. f2-f4 e5xf4
3. Ng1-f3 g7-g5
4. h2-h4 g5-g4
5. Nf3 – g5 (as an alternative to 5. Nf3 – e5, the Kieseritzky gambit )

Now 5.… f7 – f6 would be a mistake that weakens the diagonal h5 – e8 (White wins after 6. Qd1xg4 f6xg5 7. Qg4 – h5 + Ke8 – e7 8. Qh5xg5 + Ng8 – f6 9. e4 – e5 the knight back, 8 .… Ke7 – e8 9. Qg5 – h5 + along with Qe5 + even improves quality ).

Carl Schlechter suggested 5.… Ng8 – f6.

5.… d5 was Ponziani's idea.

After 5.… h7 – h6 the piece sacrifice 6. Ng5xf7 Kg8xf7 is forced. White can then continue the attack with 7. Bf1 – c4 + d7 – d5 8. Bc4xd5 + Kf7 – g7 9. d2 – d4 (9. Bd5xb7 f4 – f3!) Or 7. d2 – d4.

Also possible is the train 7. Sb1-c3, after which the answer Nb8-c6 in the Hamppe-Allgaier gambit on forwards , which also from the Vienna Game arise (can 1. e2-e4 e7-e5 2. Sb1-c3 Nb8 –C6 3. f2 – f4 etc.) and goes back to Carl Hamppe . Glazkov recommends 7.… f4 – f3 8. d2 – d4 Bf8 – e7, 7.… Nf6 is even stronger.

The prevailing view is that the figure gambit is incorrect. In practice, however, White receives a strong attack on the king, which Black takes some effort to defend against.
