The Vienna variation of the Queen’s Gambit is notable for a line in which the pieces conduct an elaborate dance around respective captures on opposite sides of the board. The variation has come into prominence as a result of a game from the recently concluded Berlin Candidates tournament. On the whole, in spite of the tactical complexities, Black appears to be emerging with safety, as is explained in the new book Queen’s Gambit Declined: Vienna by Krzysztof Panczyk and Jacek Ilczuk (Everyman Chess).
