In chess, the Kieseritzky Gambit is an opening line in the King's Gambit. It begins with the moves:
Following Black's attempt to hold the sacrificed pawn by 3...g5, White reacts by immediately undermining the pawn chain. It is one of the main lines of the King's Gambit after 3...g5, and its overall assessment is still unclear but approximately equal. The Encyclopaedia of Chess Openings classifies the Kieseritzky Gambit under code C39. C39 is also the code for the Allgaier Gambit, in which White plays 5.Ng5?!, sacrificing the knight for an attack after 5...h6 6.Nxf7 Kxf7. The Allgaier Gambit is considered dubious by modern theory.
