Falkbeer Countergambit


The Falkbeer Countergambit is a chess opening that begins with the moves:
It is a common response to the King's Gambit. In this, Black rejects the pawn offered as a sacrifice, instead opening the to enable quick, aiming to exploit White's weakness on the. After the standard capture, 3.exd5, Black may reply with 3...exf4, transposing into the King's Gambit#King's [Gambit Accepted|King's Gambit Accepted], 3...e4, or the more modern 3...c6.
A well-known blunder in this opening is White's reply 3.fxe5, which after 3...Qh4+, loses a rook for nothing or a queen for a bishop.
The opening bears the name of Austrian master Ernst Falkbeer who played it in an 1851 game against Adolf Anderssen. The Encyclopaedia of [Chess Openings] codes for the Falkbeer Countergambit are C31 and C32.

Old Main Line: 3.exd5 e4

In this variation, Black's compensation for the sacrificed pawn primarily consists of his lead in, coupled with the exposure of White's king. A typical line may run: 4.d3 Nf6 5.dxe4 Nxe4 6.Nf3 Bc5, where Black aims for the weakness on f2. In Maehrisch-Ostrau 1923, a game between Rudolf Spielmann and Siegbert Tarrasch continued: 7.Qe2 Bf5 8.g4 8...0-0 9.gxf5 Re8 and Black has a tremendous position, as he is bound to regain material and White's positional deficiencies will remain.
This line fell out of favor after World War II, as new resources for White were discovered, with players eventually turning to the next idea, but the line still sees some play.
Common lines other than the main line include the Rubinstein Variation and the Nimzowitsch Variation. The line 4.d3 Nf6 5.Nc3 Bb4 6.Bd2 e3 is known as the Morphy Gambit.

Nimzowitsch-Marshall Countergambit: 3.exd5 c6

This has become the most commonly played move after 3.exd5, with its most notable advocate being John Nunn. It is usually attributed to Aron Nimzowitsch, who successfully played it in Spielmann–Nimzowitsch, Munich 1906. However, Frank Marshall actually introduced the move to master play, defeating Richard Teichmann in 34 moves at Ostend 1905. Annotating that game in his 1914 book Marshall's Chess "Swindles", Marshall described his 3...c6 as "An innovation."
Although Black won both of those games, 3...c6 languished in obscurity for many years thereafter. White can respond with 4.Qe2, despite the drastic defeat inflicted on the young Alexander Alekhine by Paul Johner at Carlsbad 1911, although 4.Nc3 exf4 is much more common. The resulting positions are analogous to the Modern Defense of the, in which White plans to attack using a 4–2 pawn, with Black relying on piece activity and the cramping pawn on f4 to play against White's king. Theory has not reached a definitive verdict, but the resulting positions are believed to offer Black more chances than 3...e4.
