Albin's Counter Gambit (1.d4 d5 2.c4 e5) has been, and still is, a rare guest at top level tournaments, and is hardly ever seen in the practice of the world champions. The variation is considered theoretically dubious and as an overly aggressive attempt to gain counterplay in the rather solid Queen's Gambit. However, the opening has found its way into literature - in the novel "Gambit" by American crime writer Rex Stout.
