Good use of, in my view, an unorthodox version of the opening. Zukertort vs Blackburne, 1883  (D05) Queen's Pawn Game, 41 moves, 1-0 Shows the way to destroy the unorthodox version. W N Potter vs Blackburne, 1876  (D05) Queen's Pawn Game, 71 moves, 0-1 Using a passed pawn and some great moves to win. C F Burille vs D G Baird, 1889   (D05) Queen's Pawn Game, 35 moves, 0-1 3 games
