Caro-Kann Defence:Bronstein-Larsen Variation 
Black has voluntarily opted for an inferior kingside pawn structure and a practical necessity of castling queenside, but also has some compensation in the form of the open g-file for the rook and unusually active play for the Caro-Kann. It is generally considered somewhat more unsound than 5...exf6, but former top-10 player Bent Larsen employed it with some success during the 1970s.
