Threatening to win the Queen by 14. ... Q to K 2, and 15. ... B to Kt 2.

14.P to Q Kt 3...

To be able to play, in reply to 14. ... Q to K 2; 15 B to R 3. This avoids the immediate danger, but White has no tangible advantage.

An important modification of this is the Allgaier-Thorold, in which White at move 7 advances the Queen's pawn, instead of at once checking after the sacrifice of the Knight. The following is an example of this Gambit, and a probable continuation.
