King's Gambit Accepted: Allgaier

What Is The Allgaier?

4...g4 attacks the f3 knight, and 5.Ng5 refuses to retreat: the knight sits on g5 to land on f7 and drag the black king into the open. After ...h6 the knight has no square, so giving it up on f7 is the plan and not an accident. 5...Nf6 is a well prepared answer, because after 6.Nxf7 Kxf7 it already guards e4, d5 and h5, blunting the checks that give the Allgaier its bite.

White's payment for the piece is the centre, d4 and e4 together, the f-file after Bxf4, and a black king stuck on f7 with no shelter. Black wins by giving material back at the right moment and walking the king to g7. White wins by opening lines before that happens. Time, not material, settles it.

How Do You Beat The King's Gambit Accepted: Allgaier?

No data covers this position, so this is understanding rather than measurement. White has sacrificed a knight on g5 to drag your king to f7, which is the most speculative idea in the entire King's Gambit family.

A sacrifice that only wins if you cooperate is refuted by declining to cooperate, so return material rather than clinging to it. The defensive method is to give back a piece or the extra pawns at the moment it lets you finish development and get the king to safety. Grabbing everything and hoping to survive is how these games are lost. If the attack burns out, White is simply a piece down with nothing to show.
