The Polish Defense is the name commonly given to one of several sequences of chess opening moves characterized by an early ...b5 by Black. The name "Polish Defense" is given by analogy to the Polish Opening, 1.b4. The original line was
as played by Alexander Wagner, a Polish player and openings analyst, against Kuhn in the 1913 Swiss Correspondence Championship. Wagner published an analysis of the opening in Deutsches Wochenschach in 1914, when he was living in Stanislau, Galicia, Austria-Hungary (now Ivano-Frankivsk, Ukraine).
Later the name was also applied to
and other lines in which Black plays an early ...b7-b5, which are sometimes called the Polish Defense Deferred.
