Kieseritzky Gambit
In chess, the Kieseritzky Gambit is an opening line in the King's Gambit. It begins with the moves:
This is the main line of the Classical Variation (3...g5) and one of the main lines of the King's Gambit in general. After Black attempts to establish defense of the pawn on f4, White reacts by immediately undermining the pawn chain with 4.h4, where Black has little choice but to play 4...g4. The gambit's overall assessment is still unclear but approximately equal. Boris Spassky used it to defeat Bobby Fischer in 1960, leading Fischer to develop the Fischer Defense (3...d6).
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.
The opening now known as the Kieseritzky Gambit was first described by Polerio in the late 16th century. Greco also included a game with this opening in his 1620 collection. It was also analyzed by Salvio (1604) and Philidor (1749). In the first edition of the Handbuch in 1843, 5.Ne5 was considered under the heading of the Allgaier Gambit, but the editors noted that Kieseritzky had contributed significantly to the theory of 5.Ne5, which they advocated as superior to 5.Ng5 (an opinion shared by almost all subsequent analysts). The corresponding chapter in the second edition of the Handbuch in 1852 was headed "Allgaier and Kieseritzky's Gambit". Subsequently, the name Kieseritzky Gambit came into general use for 5.Ne5, Allgaier Gambit being used exclusively for 5.Ng5.
5...Nf6 is the most common reply, attacking White's weak pawn on e4 and exerting control over central squares.
White almost always responds with 6.Bc4, 6.Nxg4, or 6.d4. 6.Nxg4 is relatively drawish compared to the other options.
The line most often continues 6...d5 7.exd5 Bd6 8.d4 Nh5 which is also known as the Anderssen Defense and is considered the main line of the Kieseritzky Gambit itself. After 9.0-0 Qxh4 10.Qe1 Qxe1 11.Rxe1 the position is approximately equal. A relatively untested try is 9.Nc3!?, when one possible line is 9...Qe7 10.0-0 Bxe5 11.Nb5!. Dubbed the "Flude Line" by Shaw after the Australian correspondence player David Flude, it often leads to wild complications that are difficult for either side to navigate at the board.
The Rice Gambit, 6...d5 7.exd5 Bd6 8.0-0?!, has been discredited.
