A King's Gambit Accepted variation (1.e4 e5 2.f4 exf4 3.Nf3 d5) (ECO classification - C36). The name comes from a tournament, Abbazia 1912, in which all the games had to be a King's Gambit Accepted. The event was won by Rudolf Spielmann, Abbazia is now the city of Opatija in former Yugoslavia, now Croatia. This variation was played six times at Abbazia, Black winning four times. The opening is also known as the Polerio variation, Scandanavian Variation, or Modern Defense. In 1829, Hirsch Silberschmidt published a chess book containing analysis of this variation. It was probably first played between the Amsterdam Chess Club and the Antwerp Chess Club by correspondence in 1827.
