Elephant Gambit

The Elephant Gambit (also called the Queen's Pawn Countergambit, Englund Counterattack or Turkish Gambit) is a rarely played chess opening beginning with the moves: The Elephant Gambit is generally considered unsound, with black typically unable to gain compensation for the sacrificed pawn.

White is able to capture either of Black's center pawns with the advantage, either by 3.exd5 or 3.Nxe5.

Black's responses to 3.exd5 include 3...e4 and 3...Bd6 (the Elephant Gambit proper).

3...Qxd5 saves the pawn, but leaves White with a big lead in development after 4.Nc3.

After 3...Bd6 4.d4 e4 5.Ne5 Nf6 6.Nc3 0-0 7.Bc4, according to de Firmian, White enjoys a distinct superiority but no immediate attack.
